Silicon's Conductivity

Authors: George Rajna
Comments: 78 Pages.

"When we use the two-photon method on thicker samples we may produce even lower carrier densities that we can then probe with the THz pulses," Heilweil said. [48] Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications. [47] Physicists at the University of Alberta in Canada have developed a new way to build quantum memories, a method for storing delicate quantum information encoded into pulses of light. [45] Now, an Australian research team has experimentally realised a crucial combination of these capabilities on a silicon chip, bringing the dream of a universal quantum computer closer to reality. [44] A theoretical concept to realize quantum information processing has been developed by Professor Guido Burkard and his team of physicists at the University of Konstanz. [43] As the number of hacks and security breaches rapidly climbs, scientists say there may be a way to make a truly unhackable network by using the laws of quantum physics. [42] This world-first nanophotonic device, just unveiled in Nature Communications, encodes more data and processes it much faster than conventional fiber optics by using a special form of 'twisted' HYPERLINK "https://phys.org/tags/light/" light. [41] Purdue University researchers created a new technique that would increase the secret bit rate 100-fold, to over 35 million photons per second. [40] Physicists at The City College of New York have used atomically thin two-dimensional materials to realize an array of quantum emitters operating at room temperature that can be integrated into next generation quantum communication systems.

Helical Quantum Hall Phase in Graphene

Authors: George Rajna
Comments: 39 Pages.

In a new report now on Science, Louis Veyrat and a research team in materials science, quantum optics and optoelectronics in France, China and Japan tuned the ground state of the graphene zeroth Landau level i.e. orbitals occupied by charged particles with discrete energy values. [23] Combining our nano-SQUID on tip with scanning gate measurements in the quantum Hall phase of graphene we were able to measure and identify work and heat dissipation processes separately. [22] Probing the properties of a Mott insulator, a team of researchers from Boston College, MIT, and U.C. Santa Barbara has revealed an elusive atomic-scale magnetic signal in the unique material as it transitions from insulator to a metal, the team reported recently in the journal Nature Physics. [21] UC Santa Barbara engineer Galan Moody, an assistant professor of electrical and computer engineering, has proposed a solution to overcome the poor efficiency and performance of existing quantum computing prototypes that use light to encode and process information. [20] JILA physicists and collaborators have demonstrated the first next-generation "time scale"-a system that incorporates data from multiple atomic clocks to produce a single highly accurate timekeeping signal for distribution. [19] Researchers have succeeded in creating an efficient quantum-mechanical light-matter interface using a microscopic cavity. [18] Our researchers were the first to produce these knots as part of a collaboration between Aalto University and Amherst College, U.S., and they have now studied how the knots behave over time. [17] The groundbreaking result sheds light on an elusive phenomenon whose existence, a natural outcome of the hundred-year-old theory of superconductivity, has long been speculated, but never actually observed. [16] Now a team of researchers from the University of Maryland (UMD) Department of Physics together with collaborators has seen exotic superconductivity that relies on highly unusual electron interactions.

New State of Matter

Authors: George Rajna
Comments: 48 Pages.

Now, physicists at Northeastern have discovered a new way to manipulate electric charge. And the changes to the future of our technology could be monumental. [31] A team of scientists has discovered the first robust example of a new type of magnet-one that holds promise for enhancing the performance of data storage technologies. [30] Single-molecule magnets (SMMs) have been attracting a lot of attention recently. This is because of the increased demand for faster, longer-lasting and lower-energy IT systems, and the need for higher data storage capacity. [29] Researchers have discovered that using an easily made combination of materials might be the way to offer a more stable environment for smaller and safer data storage, ultimately leading to miniature computers. [28] demonstrated an original layout of a prototype of multiresonator broadband quantum-memory interface. [27] New nanoparticle-based films that are more than 80 times thinner than a human hair may help to fill this need by providing materials that can holographically archive more than 1000 times more data than a DVD in a 10-by-10-centimeter piece of film. [26] Researches of scientists from South Ural State University are implemented within this area. [25] Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times faster through terahertz microchips. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23]

Magnetic Nano Tornadoes

Authors: George Rajna
Comments: 48 Pages.

"We've only really been able to observe these behaviours in thin films, which are essentially two dimensional, and which therefore don't give us a complete picture." [32] The Cracow-based analyses also suggest that the magnetic phenomena occurring in magnonic crystals are more complex than previously predicted. [31] McHenry's group, in collaboration with the National Energy Technology Laboratory (NETL), NASA Glenn Research Center, and North Carolina State University, are designing a two and half kilowatt motor that weighs less than two and half kilograms. [30] Single-molecule magnets (SMMs) have been attracting a lot of attention recently. This is because of the increased demand for faster, longer-lasting and lower-energy IT systems, and the need for higher data storage capacity.

[23] An exotic state of matter that is dazzling scientists with its electrical properties, can also exhibit unusual optical properties, as shown in a theoretical study by researchers at A*STAR. [22]

Control Spin of Atom-like Impurities

Authors: George Rajna
Comments: 43 Pages.

A team of international scientists investigating how to control the spin of atom-like impurities in 2-D materials have observed the dependence of the atom's energy on an external magnetic field for the first time. [26] The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. [25] A research team from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has found the first evidence that a shaking motion in the structure of an atomically thin (2-D) material possesses a naturally occurring circular rotation. [24] Topological effects, such as those found in crystals whose surfaces conduct electricity while their bulk does not, have been an exciting topic of physics research in recent years and were the subject of the 2016 Nobel Prize in physics. [23] A new technique developed by MIT researchers reveals the inner details of photonic crystals, synthetic materials whose exotic optical properties are the subject of widespread research. [22] In experiments at SLAC, intense laser light (red) shining through a magnesium oxide crystal excited the outermost "valence" electrons of oxygen atoms deep inside it. [21] LCLS works like an extraordinary strobe light: Its ultrabright X-rays take snapshots of materials with atomic resolution and capture motions as fast as a few femtoseconds, or millionths of a billionth of a second. For comparison, one femtosecond is to a second what seven minutes is to the age of the universe. [20] A 'nonlinear' effect that seemingly turns materials transparent is seen for the first time in X-rays at SLAC's LCLS. [19] Leiden physicists have manipulated light with large artificial atoms, so-called quantum dots. Before, this has only been accomplished with actual atoms. It is an important step toward light-based quantum technology. [18] In a tiny quantum prison, electrons behave quite differently as compared to their counterparts in free space. They can only occupy discrete energy levels, much like the electrons in an atom-for this reason, such electron prisons are often called "artificial atoms". [17] When two atoms are placed in a small chamber enclosed by mirrors, they can simultaneously absorb a single photon. [16]

Electron-Hole in Perovskites

Authors: George Rajna
Comments: 46 Pages.

A research team led by Prof. Zhao Jin from Department of Physics, University of Science and Technology of China (USTC) of the Chinese Academy of Sciences found low-frequency lattice phonons in halide perovskites resulting in high defect tolerance toward electron-hole recombination with their independently-developed software, Hefei-NAMD. [30] In the perspective, Gabor and Song collect early examples in electron metamaterials and distil emerging design strategies for electronic control from them. [29] Lawrence Livermore National Laboratory (LLNL) researchers are working to make better electronic devices by delving into the way nanocrystals are arranged inside of them. [28]

Portable and Non-invasive Blood Glucose Monitoring over a Prolonged Period using Whispering Gallery Modes at 2.4 GHz

Authors: Louis WY Liu, Son Nguyen Thanh, Khanh Nguyen Tuan
Comments: 14 Pages.

Invasive measurement of blood glucose is not appropriate for everyone, particularly the patients with leukemia. Here, we demonstrate how the blood glucose can be non-invasively monitored over a prolonged period in the absence of any expensive equipment. Method: A portable and non-invasive glucose sensor capable of monitoring blood glucose in real-time has been successfully constructed and tested in the absence of any vector network analyzer. Using vacuum suction, the sensor head of the proposed non-invasive glucose sensor forms a whispering gallery resonator out of a skin tissue on an arm during the measurement process. The architecture of the proposed glucose sensor is equipped with standard components, including a WIFI transmitter, an RSSI sensor and a microcontroller based computer display. Results: Using the proposed glucose sensor, a healthy volunteer has been his blood glucose levels monitored over 72 minutes after consuming a loaf of bread and a cup of cow milk. The measured blood glucose rose shortly after the meal until it peaked at 40 minutes and finally fell to the initial value at around 72 minutes. Conclusion: The overall results were in general consistent with the expected results. The proposed glucose sensor is expected to be instrumental for the individuals who dislike the traditional lancets.

Liquid Light in Organic Materials

Authors: George Rajna
Comments: 96 Pages.

A team of scientists from the Hybrid Photonics Laboratory at the Skolkovo Institute of Science and Technology (Skoltech) and the University of Sheffield (UK) made a breakthrough in understanding nonlinear physics of the strong interaction of organic molecules with light. [55] In a new method, materials scientists Boliang Jia and colleagues at the departments of mechanical engineering and robotics presented a printable biocompatible superlens placed directly on objects of interest to observe subdiffraction-limited features (resolution beyond the diffraction limit). [54] Physicists have also devised photonic topological insulators, synthetic materials that impart light waves with distinct topological features, allowing light (rather than electric currents) to flow via topological surface states. [53] "This research highlights the cutting-edge research being done at WVU, and we are very excited to see their work appear in the very high-profile journal Nature Communications." [52] By constructing a hybrid device made from two different types of qubit-the fundamental computing element of quantum computers-they have created a device that can be quickly initialized and read out, and that simultaneously maintains high control fidelity. [51] Researchers have demonstrated that an amoeba-a single-celled organism consisting mostly of gelatinous protoplasm-has unique computing abilities that may one day offer a competitive alternative to the methods used by conventional computers. [50] For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew. [49] Physical systems with discrete energy levels are ubiquitous in nature and form fundamental building blocks of quantum technology. [48] In a similar vein, scientists are working to create twisting helical electromagnetic waves whose curvature allows more accurate imaging of the magnetic properties of different materials at the atomic level and could possibly lead to the development of future devices.

High-Capacity EV Battery Materials

Authors: George Rajna
Comments: 66 Pages.

The batteries currently installed in mass-produced electric vehicles use graphite anode materials, but their low capacity contributes to electric vehicles' having a shorter driving range than vehicles with internal combustion engines. [41] Now a team of Australian scientists has discovered diamond can be bent and deformed, at the nanoscale at least. [40] Researchers at the Okinawa Institute of Science and Technology Graduate University (OIST) have fabricated a novel glass and synthetic diamond foundation that can be used to create miniscule micro-and nanostructures. [39] Osaka University-led researchers demonstrated that the perturbation of laser imprinting on a capsule for nuclear fusion fuel made from stiff and heavy materials was mitigated. [38] Scientists found that relatively slow electrons are produced when intense lasers interact with small clusters of atoms, upturning current theories. [37] Lasers that emit ultrashort pulses of light are critical components of technologies, including communications and industrial processing, and have been central to fundamental Nobel Prize-winning research in physics. [36] A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. [35] The unique platform, which is referred as a 4-D microscope, combines the sensitivity and high time-resolution of phase imaging with the specificity and high spatial resolution of fluorescence microscopy. [34] The experiment relied on a soliton frequency comb generated in a chip-based optical microresonator made from silicon nitride. [33] This scientific achievement toward more precise control and monitoring of light is highly interesting for miniaturizing optical devices for sensing and signal processing. [32]

Comments: 69 Pages.

The researchers found that clusters of oxygen vacancies along the nanowire surface activate adsorbed water molecules during the photocatalytic generation of hydroxyl radicals-an important intermediate in the production of chemical fuels, including hydrogen gas and methanol, from sunlight.

Custom Light Using 2-D Materials

Authors: George Rajna
Comments: 97 Pages.

Today, researchers from the University of Geneva (UNIGE), Switzerland, in collaboration with the University of Manchester, have discovered an entire class of two-dimensional materials that are the thickness of one or a few atoms. [56] A team of scientists from the Hybrid Photonics Laboratory at the Skolkovo Institute of Science and Technology (Skoltech) and the University of Sheffield (UK) made a breakthrough in understanding nonlinear physics of the strong interaction of organic molecules with light. [55] In a new method, materials scientists Boliang Jia and colleagues at the departments of mechanical engineering and robotics presented a printable biocompatible superlens placed directly on objects of interest to observe subdiffraction-limited features (resolution beyond the diffraction limit).

Carbon-Nanotube-Based Fibers

Authors: George Rajna
Comments: 67 Pages.

The Lyding Group recently developed a technique that can be used to build carbon-nanotube-based fibers by creating chemical crosslinks. [46] Swansea University scientists have reported a new approach to measuring the conductivity between identical carbon nanotubes which could be used to help improve the efficiency of electrical power cables in the future. [45] By using nanocapsules, scientists and industrial partners are developing innovative garments and skin products that provide thermal comfort, and anti-aging and antimicrobial properties. [44] In a new study, researchers at the University of Illinois and the Missouri University of Science and Technology modeled a method to manipulate nanoparticles as an alternative mode of propulsion for tiny spacecraft that require very small levels of thrust. [43] As if they were bubbles expanding in a just-opened bottle of champagne, tiny circular regions of magnetism can be rapidly enlarged to provide a precise method of measuring the magnetic properties of nanoparticles. [42] Antennas made of carbon nanotube films are just as efficient as copper for wireless applications, according to researchers at Rice University's Brown School of Engineering. [41] The device is a high-efficiency round-trip light tunnel that squeezes visible light to the very tip of the condenser to interact with molecules locally and send back information that can decipher and visualize the elusive nanoworld. [40] "Smart glass," an energy-efficiency product found in newer windows of cars, buildings and airplanes, slowly changes between transparent and tinted at the flip of a switch. [39] With international collaboration, researchers at Aalto University have now developed a nanosized amplifier to help light signals propagate through microchips. [38] Physicists at the Kastler Brossel Laboratory in Paris have reached a milestone in the combination of cold atoms and nanophotonics. [37] The universal laws governing the dynamics of interacting quantum particles are yet to be fully revealed to the scientific community. [36] Now NIST scientists have designed a vacuum gauge that is small enough to deploy in commonly used vacuum chambers. [35]

Isolate Atomic Sheets for New Materials

Authors: George Rajna
Comments: 53 Pages.

Columbia University researchers report today in Science that they have invented a new method-using ultraflat gold films-to disassemble vdW single crystals layer by layer into monolayers with near-unity yield and with dimensions limited only by bulk crystal sizes. [36] Heterostructures with magnetism and topology (geometry) are promising materials to realize exotic topological quantum states. [35] Topological materials have become a hot topic in quantum materials research, as they have potential applications for quantum information and spintronics. [34] The team utilized analytical and ab-initio theories to establish a link between this spin engine concept and room-temperature experiments on a solid-state spintronic device called a magnetic tunnel junction (MTJ). [33] Scientists at Tokyo Institute of Technology proposed new quasi-1-D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons. [32] They do this by using "excitons," electrically neutral quasiparticles that exist in insulators, semiconductors and in some liquids. [31] Researchers at ETH Zurich have now developed a method that makes it possible to couple such a spin qubit strongly to microwave photons. [30] Quantum dots that emit entangled photon pairs on demand could be used in quantum communication networks. [29] Researchers successfully integrated the systems-donor atoms and quantum dots. [28] A team of researchers including U of A engineering and physics faculty has developed a new method of detecting single photons, or light particles, using quantum dots. [27] Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms. [26] Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. [25] The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing. [24]

Graphene-Based Phase Control of Light

Authors: George Rajna
Comments: 78 Pages.

Researchers described a new strategy of designing metamolecules that incorporates two independently controllable subwavelength meta-atoms. [49] Researchers at the University of Manchester have uncovered interesting phenomena when multiple two-dimensional materials are combined into van der Waals heterostructures (layered "sandwiches" of different materials). [48] "The junctions were reproducible over several devices and operated from 20 Kelvin up to room temperature. Our approach represents a simple but powerful strategy for the future integration of molecule-based functions into stable and controllable nanoelectronic devices." [47] The team has turned graphene oxide (GO) into a soft, moldable and kneadable play dough that can be shaped and reshaped into free-standing, three-dimensional structures. [46]

Van der Waals Magnets Semiconductors

Authors: George Rajna
Comments: 53 Pages.

In 2017, 2-D van der Waals materials that show magnetic properties were discovered, stimulating research projects and studies all around the world. [33] The researchers expect the work principle to manipulate 2-D magnetism by engineering unique spatially dependent spin textures for a variety of applications with vDW materials. [32] Researchers at Cardiff University have shown tiny light-emitting nanolasers less than a tenth of the size of the width of a human hair can be integrated into silicon chip design. [31] Large-scale plasmonic metasurfaces could find use in flat panel displays and other devices that can change colour thanks to recent work by researchers at the University of Cambridge in the UK. [30] Particles in solution can grow, transport, collide, interact, and aggregate into complex shapes and structures. [29] Lawrence Livermore National Laboratory (LLNL) researchers are working to make better electronic devices by delving into the way nanocrystals are arranged inside of them. [28] Self-assembly and crystallisation of nanoparticles (NPs) is generally a complex process, based on the evaporation or precipitation of NP-building blocks. [27] New nanoparticle-based films that are more than 80 times thinner than a human hair may help to fill this need by providing materials that can holographically archive more than 1000 times more data than a DVD in a 10-by-10-centimeter piece of film. [26] Researches of scientists from South Ural State University are implemented within this area. [25] Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times faster through terahertz microchips. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23]

Fast Light Detector

Authors: George Rajna
Comments: 71 Pages.

Two research groups at ETH Zurich have joined forces to develop a novel light detector. It consists of two-dimensional layers of different materials that are coupled to a silicon optical waveguide. [42] To enable negative refraction and related optical illusions, metamaterials are artificially engineered with unique properties that result from their internal physical structures, rather than their chemical composition. [41] Femtosecond X-ray experiments in combination with a new theoretical approach establish a direct connection between electric properties in the macroscopic world and electron motions on the time and length scale of atoms. [40] Novel insight comes now from experiments and simulations performed by a team led by ETH physicists who have studied electronic transport properties in a one-dimensional quantum wire containing a mesoscopic lattice. [39] Femtosecond lasers are capable of processing any solid material with high quality and high precision using their ultrafast and ultra-intense characteristics. [38] To create the flying microlaser, the researchers launched laser light into a water-filled hollow core fiber to optically trap the microparticle. Like the materials used to make traditional lasers, the microparticle incorporates a gain medium. [37] Lasers that emit ultrashort pulses of light are critical components of technologies, including communications and industrial processing, and have been central to fundamental Nobel Prize-winning research in physics.

Scientists at Rice University, the University of Tennessee, Knoxville (UT Knoxville) and Oak Ridge National Laboratory (ORNL) are using a very small visible beam to burn the foamy form of carbon into microscopic patterns. [39] Femtosecond lasers are capable of processing any solid material with high quality and high precision using their ultrafast and ultra-intense characteristics. [38] To create the flying microlaser, the researchers launched laser light into a water-filled hollow core fiber to optically trap the microparticle. Like the materials used to make traditional lasers, the microparticle incorporates a gain medium. [37]

Comments: 64 Pages.

Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory have developed a new technique that could potentially help make these increasingly small but complex devices. [39] Quantum wells of the highest quality are typically fabricated by molecular beam epitaxy (sequential growth of crystalline layers), which is a well-established technique. [38] Scientists found that relatively slow electrons are produced when intense lasers interact with small clusters of atoms, upturning current theories. [37]

Authors: George Rajna
Comments: 59 Pages.

Quasiparticle Semiconductors Physicists from Switzerland and Germany have unveiled fingerprints of the long-sought particle known as the Mahan exciton in the room temperature optical response of the popular methylammonium lead halide perovskites. [36] These exotic particles can, for example, emerge as quasi-particles in topological superconductors and represent ideal building blocks for topological quantum computers. [35] This event is considered as a striking proof of the existence of Majorana particles, and it represents a crucial step towards their use as building blocks for the development of quantum computers. [34] In the latest experiment of its kind, researchers have captured the most compelling evidence to date that unusual particles lurk inside a special kind of superconductor. [33] With their insensitivity to decoherence, Majorana particles could become stable building blocks of quantum computers. [32] A team of researchers at the University of Maryland has found a new way to route photons at the micrometer scale without scattering by building a topological quantum optics interface. [31] Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information. [30] Theoretical physicists propose to use negative interference to control heat flow in quantum devices. [29] Particle physicists are studying ways to harness the power of the quantum realm to further their research. [28]

For Leslie Schoop's lab, one recent such investigation has uncovered a layered compound with a trio of properties not previously known to exist in one material. [31] McHenry's group, in collaboration with the National Energy Technology Laboratory (NETL), NASA Glenn Research Center, and North Carolina State University, are designing a two and half kilowatt motor that weighs less than two and half kilograms. [30] Single-molecule magnets (SMMs) have been attracting a lot of attention recently. This is because of the increased demand for faster, longer-lasting and lower-energy IT systems, and the need for higher data storage capacity. [29] Researchers have discovered that using an easily made combination of materials might be the way to offer a more stable environment for smaller and safer data storage, ultimately leading to miniature computers.

Comments: 51 Pages.

A method to observe a new class of topological materials, called Weyl semimetals, was developed by researchers at Penn State, MIT, Tohoku University, Japan and the Indonesian Institute of Sciences. [32] Solar energy is clean and abundant. But when the sun isn't shining, you must store the energy in batteries or through a process called photocatalysis-in which solar energy is used to make fuels. [31] An international team of scientists, including NUST MISIS's Professor Gotthard Seifert, has made an important step toward the control of excitonic effects in two-dimensional van der Waals heterostructures. [30] Carbon nanotubes-cylindrical formations of carbon atoms with incredible strength and electrical conductivity-hold great promise for creating new micron-scale low-power electronic devices. [29] An electrically conductive hydrogel that takes stretchability, self-healing and strain sensitivity to new limits has been developed at KAUST. [28] UCLA scientists and engineers have developed a new process for assembling semiconductor devices. [27] A new experiment that tests the limit of how large an object can be before it ceases to behave quantum mechanically has been proposed by physicists in the UK and India. [26] Phonons are discrete units of vibrational energy predicted by quantum mechanics that correspond to collective oscillations of atoms inside a molecule or a crystal. [25] This achievement is considered as an important landmark for the realization of practical application of photon upconversion technology. [24] Considerable interest in new single-photon detector technologies has been scaling in this past decade. [23] Engineers develop key mathematical formula for driving quantum experiments. [22]

Atom-Scale Materials the Next Tech

Authors: George Rajna
Comments: 67 Pages.

"Atomaterials" is short for "atomic materials," so called because their properties depend on the precise configuration of their atoms. It is a new but rapidly developing field. [42] Using straightforward chemistry and a mix-and-match, modular strategy, researchers have developed a simple approach that could produce over 65,000 different types of complex nanoparticles, each containing up to six different materials and eight segments, with interfaces that could be exploited in electrical or optical applications. [41] MIT engineers have shown that they can enhance the performance of drug-delivery nanoparticles by controlling a trait of chemical structures known as chirality-the "handedness" of the structure. [40] The process, developed by Nagoya University researchers in Japan, could be upscaled for manufacturing purified batches of single-wall carbon nanotubes that can be used in high-performance electronic devices. [39] Scientists at Texas Heart Institute (THI) and Rice University have used biocompatible fibres made of carbon nanotubes (CNTs) as electrical bridges to restore conductivity to damaged hearts. [38] A team of researchers from China, the U.S. and Japan has developed a way to strengthen graphene-based membranes intended for use in desalination projects-by fortifying them with nanotubes. [37] The team arrived at their results by imaging gold nanoparticles, with diameters ranging from 2 to 5 nanometres, via aberration corrected scanning transmission electron microscope. [36] Nanoparticles of less than 100 nanometres in size are used to engineer new materials and nanotechnologies across a variety of sectors. [35] For years, researchers have been trying to find ways to grow an optimal nanowire, using crystals with perfectly aligned layers all along the wire. [34] Ferroelectric materials have a spontaneous dipole moment which can point up or down. [33] Researchers have successfully demonstrated that hypothetical particles that were proposed by Franz Preisach in 1935 actually exist. [32]

Atomic Dance of 2-D Materials

Authors: George Rajna
Comments: 63 Pages.

A team of Northwestern University materials science researchers have developed a new method to view the dynamic motion of atoms in atomically thin 2-D materials. [39] Researchers led by MIT Department of Physics Professor Pablo Jarillo-Herrero last year showed that rotating layers of hexagonally structured graphene at a particular "magic angle" could change the material's electronic properties from an insulating state to a superconducting state. [38] Scientists at the University of Hong Kong and Hunan Normal University showed that, in homobilayer transition metal dichalcogenides, the real-space Berry phase from moiré patterns manifests as a periodic magnetic field. [37] In a paper published today in Nature's NPJ Quantum Information, Omar Magaña-Loaiza, assistant professor in the Louisiana State University (LSU) Department of Physics & Astronomy, and his team of researchers describe a noteworthy step forward in the quantum manipulation and control of light, which has far-reaching quantum technology applications in imaging, simulation, metrology, computation, communication, and cryptography, among other areas.

Researchers at the University of Antwerp report how higher-order periodic modulations called supermoiré caused by the encapsulation of graphene between hexagonal boron nitride affect the electronic and structural properties of graphene, as revealed in three recent independent experiments. [45] Graphene-based computer components that can deal in terahertz "could be used, not in a normal Macintosh or PC, but perhaps in very advanced computers with high processing rates," Ozaki says. This 2-D material could also be used to make extremely high-speed nanodevices, he adds. [44] Printed electronics use standard printing techniques to manufacture electronic devices on different substrates like glass, plastic films, and paper. [43]

[52] The findings describe an entirely new state of matter, the researchers say, that will require a new theoretical explanation. [51] This area of research aims to greatly accelerate the study of spintronics with organic molecules.

Gold-Based Electrocatalysts

Comments: 41 Pages.

A RUDN chemist has synthesized an electrocatalyst based on gold nanoparticles with organic ligands that can trigger both hydrogen production reactions and oxygen reduction reactions in fuel cells. [31] Freestanding clusters of 20 gold atoms take the shape of a pyramid, researchers have discovered. [30] The multimodal nanoscience approach to studying quantum physics phenomena is, they say, a "technological leap for how scientists can explore quantum materials to unearth new phenomena and guide future functional engineering of these materials for real-world applications." [29] Researchers have developed a three-dimensional dynamic model of an interaction between light and nanoparticles. [28] Scientists from ITMO University have developed effective nanoscale light sources based on halide perovskite. [27] Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. [26] Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. [25] The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing. [24] In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin (TU) and the University of Rostock have managed for the first time to image free nanoparticles in a laboratory experiment using a highintensity laser source. [23] For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature. [22] A team of engineers at Caltech has discovered how to use computer-chip manufacturing technologies to create the kind of reflective materials that make safety vests, running shoes, and road signs appear shiny in the dark.

Metal Clusters Nanotechnology

Authors: George Rajna
Comments: 57 Pages.

When metal atoms form small clusters of a particular size, they show interesting and potentially useful electromagnetic characteristics, which are different from those of the actual bulk metal. [39] An international research team around physicist Wolfgang Lang at the University of Vienna has succeeded in producing the world's densest complex nano arrays for anchoring flux quanta, the fluxons. [38] Optical properties of materials are based on their chemistry and the inherent subwavelength architecture, although the latter remains to be characterized in depth. [37] More than 100 years ago, Albert Einstein and Wander Johannes de Haas discovered that when they used a magnetic field to flip the magnetic state of an iron bar dangling from a thread, the bar began to rotate. [36] Researchers at the Max Born Institute have now generated directed currents at terahertz (THz) frequencies, much higher than the clock rates of current electronics. [35] Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed a simple yet accurate method for finding defects in the latest generation of silicon carbide transistors. [34] In 2017, University of Utah physicist Valy Vardeny called perovskite a "miracle material" for an emerging field of next-generation electronics, called spintronics, and he's standing by that assertion. [33] Scientists at Tokyo Institute of Technology proposed new quasi-1-D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons. [32] They do this by using "excitons," electrically neutral quasiparticles that exist in insulators, semiconductors and in some liquids. [31] Researchers at ETH Zurich have now developed a method that makes it possible to couple such a spin qubit strongly to microwave photons. [30] Quantum dots that emit entangled photon pairs on demand could be used in quantum communication networks. [29] Researchers successfully integrated the systems-donor atoms and quantum dots. [28]

The researchers say this is the first ultralightweight polymer-based SSE that is fireproof. In fact, a battery they made from this SSE continued to function well even when it was exposed to flames. [30] The nano research team led by professors Helge Weman and Bjørn-Ove Fimland at the Norwegian University of Science and Technology's (NTNU) Department of Electronic Systems has succeeded in creating light-emitting diodes, or LEDs, from a nanomaterial that emits ultraviolet light. [29] Researchers at Tokyo Tech have developed a nanosized container bearing photoswitches that takes up hydrophobic compounds of various size and shape in water and subsequently releases them quantitatively by non-invasive light stimulus. [28] By studying how electrons in two-dimensional graphene can literally act like a liquid, researchers have paved the way for further research into a material that has the potential to enable future electronic computing devices that outpace silicon transistors. [27] This research is a therefore a step towards basic and technological research into 3-D analogues of QSH insulators, and may ultimately lead to new electronic and spintronic technologies. [26] Topological insulators (TIs) host exotic physics that could shed new light on the fundamental laws of nature. [25] A new study by scientists from the University of Bristol brings us a significant step closer to unleashing the revolutionary potential of quantum computing by harnessing silicon fabrication technology to build complex on-chip quantum optical circuits. [24] Two teams of scientists from the Technion-Israel Institute of Technology have collaborated to conduct groundbreaking research leading to the development of a new and innovative scientific field: Quantum Metamaterials.

New research from the School of Engineering and Applied Science shows how simple, microscopic robots, remotely driven by magnetic fields, can use capillary forces to manipulate objects floating at an oil-water interface. [31] McHenry's group, in collaboration with the National Energy Technology Laboratory (NETL), NASA Glenn Research Center, and North Carolina State University, are designing a two and half kilowatt motor that weighs less than two and half kilograms. [30] Single-molecule magnets (SMMs) have been attracting a lot of attention recently. This is because of the increased demand for faster, longer-lasting and lower-energy IT systems, and the need for higher data storage capacity.

[28] demonstrated an original layout of a prototype of multiresonator broadband quantum-memory interface. [27] New nanoparticle-based films that are more than 80 times thinner than a human hair may help to fill this need by providing materials that can holographically archive more than 1000 times more data than a DVD in a 10-by-10-centimeter piece of film. [26] Researches of scientists from South Ural State University are implemented within this area. [25] Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times faster through terahertz microchips. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23] An exotic state of matter that is dazzling scientists with its electrical properties, can also exhibit unusual optical properties, as shown in a theoretical study by researchers at A*STAR. [22]

[43] A nanoscale gold butterfly provides a more precise route for growing/synthesizing nanosized semiconductors that can be used in nano-lasers and other applications. [42] Magnetic vortices are nanoscale whirls that gyrate like spinning tops, tracing out paths in a clockwise or counterclockwise manner in nanometer-thick materials.

In a recent study, University of Arkansas physics researchers found evidence of an inverse transition in ferroelectric ultrathin films, which could lead to advances in development of data storage, microelectronics and sensors. [30] A UNSW study published today in Nature Communications presents an exciting step towards domain-wall nanoelectronics: a novel form of future electronics based on nano-scale conduction paths, and which could allow for extremely dense memory storage. [29] Two research groups from ETH Zurich have developed a method that can simulate nanoelectronics devices and their properties realistically, quickly and efficiently. [28] Dispersible electrodes based on gold-coated magnetic nanoparticles modified with DNA can detect microRNA in unprocessed blood samples at extremely low concentrations and over a broad range-a first for sensors of this kind. [27] Engineers at the University of California San Diego have developed neutrophil "nanosponges" that can safely absorb and neutralize a variety of proteins that play a role in the progression of rheumatoid arthritis. [26] An international team of researchers has determined the function of a new family of proteins associated with cancer and autism. [25] In 2016, when we inaugurated our new IBM Research lab in Johannesburg, we took on this challenge and are reporting our first promising results at Health Day at the KDD Data Science Conference in London this month. [24] The research group took advantage of a system at SLAC's Stanford Synchrotron Radiation Lightsource (SSRL) that combines machine learning-a form of artificial intelligence where computer algorithms glean knowledge from enormous amounts of data-with experiments that quickly make and screen hundreds of sample materials at a time. [23] Researchers at the UCLA Samueli School of Engineering have demonstrated that deep learning, a powerful form of artificial intelligence, can discern and enhance microscopic details in photos taken by smartphones.

Information Metasurfaces

Authors: George Rajna
Comments: 59 Pages.

In recent years, rapid developments of digital and information metasurfaces have stimulated many information processing applications, such as computational imaging, wireless communications, and performing mathematical operations. [34] The current work demonstrates how to distinguish between trivial and topological insulators at an ultra-fast rate, in other words, to "read out" the topological information of the system using laser spectroscopy. [33] Rice University physicist Qimiao Si began mapping quantum criticality more than a decade ago, and he's finally found a traveler that can traverse the final frontier. [32] Physicists studying the strange behavior of metal alloys called heavy fermions have made a surprising discovery that could be useful in safeguarding the information stored in quantum bits, or qubits, the basic units of encoded information in quantum computers. [31] Properties of complex materials are often determined by the interplay of several electron properties. TU Wien (Vienna) has now succeeded in disentangling this mess. [30] Physicists have found "electron pairing," a hallmark feature of superconductivity, at temperatures and energies well above the critical threshold where superconductivity happens. [29] It was a three-hour nighttime road trip that capped off a journey begun seven years ago. [28] Discovered more than 100 years ago, superconductivity continues to captivate scientists who seek to develop components for highly efficient energy transmission, ultrafast electronics or quantum bits for next-generation computation. [27] One of the greatest mysteries in condensed matter physics is the exact relationship between charge order and superconductivity in cuprate superconductors. [26] Cuprates hold the record high superconducting temperature at ambient pressure so far, but understanding their superconducting mechanism remains one of the great challenges of physical sciences listed as one of 125 quests announced by Science. [25] Now, scientists at Tokyo Institute of Technology (Tokyo Tech), the University of Tokyo and Tohoku University report curious multi-state transitions of these superconductors in which they change from superconductor to special metal and then to insulator.

Nanoscale Magnetic Vortex Chaos

Authors: George Rajna
Comments: 67 Pages.

Magnetic vortices are nanoscale whirls that gyrate like spinning tops, tracing out paths in a clockwise or counterclockwise manner in nanometer-thick materials. [41] Now a team of Australian scientists has discovered diamond can be bent and deformed, at the nanoscale at least. [40] Researchers at the Okinawa Institute of Science and Technology Graduate University (OIST) have fabricated a novel glass and synthetic diamond foundation that can be used to create miniscule micro-and nanostructures. [39] Osaka University-led researchers demonstrated that the perturbation of laser imprinting on a capsule for nuclear fusion fuel made from stiff and heavy materials was mitigated. [38] Scientists found that relatively slow electrons are produced when intense lasers interact with small clusters of atoms, upturning current theories. [37] Lasers that emit ultrashort pulses of light are critical components of technologies, including communications and industrial processing, and have been central to fundamental Nobel Prize-winning research in physics. [36] A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. [35] The unique platform, which is referred as a 4-D microscope, combines the sensitivity and high time-resolution of phase imaging with the specificity and high spatial resolution of fluorescence microscopy. [34] The experiment relied on a soliton frequency comb generated in a chip-based optical microresonator made from silicon nitride. [33] This scientific achievement toward more precise control and monitoring of light is highly interesting for miniaturizing optical devices for sensing and signal processing. [32] It may seem like such optical behavior would require bending the rules of physics, but in fact, scientists at MIT, Harvard University, and elsewhere have now demonstrated that photons can indeed be made to interact-an accomplishment that could open a path toward using photons in quantum computing, if not in light sabers.

Vibrations on a Chip

Authors: George Rajna
Comments: 25 Pages.

AMOLF physicists have made mechanical vibrations on a chip behave as if they were electrical currents flowing in a magnetic field. [35] The measurement confirmed that only the spin current injection of appropriate spin orientation can excite the vibration of the cantilever. [34] Manipulating the flow of energy through superconductors could radically transform technology, perhaps leading to applications such as ultra-fast, highly efficient quantum computers. [33] University of Wisconsin-Madison engineers have added a new dimension to our understanding of why straining a particular group of materials, called Ruddlesden-Popper oxides, tampers with their superconducting properties. [32] Nuclear techniques have played an important role in determining the crystal structure of a rare type of intermetallic alloy that exhibits superconductivity. [31] A potential new state of matter is being reported in the journal Nature, with research showing that among superconducting materials in high magnetic fields, the phenomenon of electronic symmetry breaking is common. [30] Researchers from the University of Geneva (UNIGE) in Switzerland and the Technical University Munich in Germany have lifted the veil on the electronic characteristics of high-temperature superconductors. Their research, published in Nature Communications, shows that the electronic densities measured in these superconductors are a combination of two separate effects. As a result, they propose a new model that suggests the existence of two coexisting states rather than competing ones postulated for the past thirty years, a small revolution in the world of superconductivity. [29] A team led by scientists at the Department of Energy's SLAC National Accelerator Laboratory combined powerful magnetic pulses with some of the brightest X-rays on the planet to discover a surprising 3-D arrangement of a material's electrons that appears closely linked to a mysterious phenomenon known as high-temperature superconductivity. [28] Advanced x-ray technique reveals surprising quantum excitations that persist through materials with or without superconductivity. [27] This paper explains the magnetic effect of the superconductive current from the observed effects of the accelerating electrons, causing naturally the experienced changes of the electric field potential along the electric wire. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the wave particle duality and the electron's spin also, building the bridge between the Classical and Quantum Theories. The changing acceleration of the electrons explains the created negative electric field of the magnetic induction, the Higgs Field, the changing Relativistic Mass and the Gravitational Force, giving a Unified Theory of the physical forces. Taking into account the Planck Distribution Law of the electromagnetic oscillators also, we can explain the electron/proton mass rate and the Weak and Strong Interactions. Since the superconductivity is basically a quantum mechanical phenomenon and some entangled particles give this opportunity to specific matters, like Cooper Pairs or other entanglements, as strongly correlated materials and Exciton-mediated electron pairing, we can say that the secret of superconductivity is the quantum entanglement.

Authors: George Rajna
Comments: 80 Pages.

A new 3D camera made from a stack of transparent graphene photodetectors can capture and focus on objects that are different distances away from the camera lens. [49] Researchers have created a unique device which will unlock the elusive terahertz wavelengths and make revolutionary new technologies possible. [48] A research team from the University of Göttingen, together with the Chemnitz University of Technology and the Physikalisch-Technische Bundesanstalt Braunschweig, has investigated the influence of the underlying crystal on the electrical resistance of graphene. [47] The team has turned graphene oxide (GO) into a soft, moldable and kneadable play dough that can be shaped and reshaped into free-standing, three-dimensional structures. [46]

Weyl Semimetals Twist to Spintronics

Authors: George Rajna
Comments: 54 Pages.

A team led by Prof LOH Kian Ping, Department of Chemistry and Centre for Advanced 2-D Materials, NUS, has identified one such promising candidate in the form of few-layer thin semimetal molybdenum ditelluride (MoTe2). [34] A particular kind of elementary particle, the Weyl fermions, were first discovered a few years ago. [33] Researchers have successfully demonstrated that hypothetical particles that were proposed by Franz Preisach in 1935 actually exist. [32] Scientists from the Department of Energy's SLAC National Accelerator Laboratory and the Massachusetts Institute of Technology have demonstrated a surprisingly simple way of flipping a material from one state into another, and then back again, with single flashes of laser light. [31] Materials scientists at Duke University computationally predicted the electrical and optical properties of semiconductors made from extended organic molecules sandwiched by inorganic structures. [30] KU Leuven researchers from the Roeffaers Lab and the Hofkens Group have now put forward a very promising direct X-ray detector design, based on a rapidly emerging halide perovskite semiconductor, with chemical formula Cs2AgBiBr6. [29] Physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have proven that incoming light causes the electrons in warm perovskites to rotate, thus influencing the direction of the flow of electrical current. [28] Self-assembly and crystallisation of nanoparticles (NPs) is generally a complex process, based on the evaporation or precipitation of NP-building blocks. [27] New nanoparticle-based films that are more than 80 times thinner than a human hair may help to fill this need by providing materials that can holographically archive more than 1000 times more data than a DVD in a 10-by-10-centimeter piece of film. [26] Researches of scientists from South Ural State University are implemented within this area. [25]

[46] A team of researchers based at The University of Manchester have found a low cost method for producing graphene printed electronics, which significantly speeds up and reduces the cost of conductive graphene inks. [45] Graphene-based computer components that can deal in terahertz "could be used, not in a normal Macintosh or PC, but perhaps in very advanced computers with high processing rates," Ozaki says. This 2-D material could also be used to make extremely high-speed nanodevices, he adds. [44] Printed electronics use standard printing techniques to manufacture electronic devices on different substrates like glass, plastic films, and paper. [43] A tiny laser comprising an array of nanoscale semiconductor cylinders (see image) has been made by an all-A*STAR team. [42] A new instrument lets researchers use multiple laser beams and a microscope to trap and move cells and then analyze them in real-time with a sensitive analysis technique known as Raman spectroscopy.

Nanoscale Lattice of Palladium and Yttrium

Authors: George Rajna
Comments: 55 Pages.

A group of materials scientists at Tokyo Institute of Technology has shown that a palladium-based intermetallic electride, Y3Pd2, can improve the efficiency of carbon-carbon cross-coupling reactions. Their findings point the way to a more sustainable world through catalysis. [36] Ashwin Shahani, an assistant professor of materials science and engineering at the University of Michigan, is working to solve the mystery of eutectic solidification, and his research has revealed an intricate and beautiful universe of nanoscale rods, sheets and spirals that form spontaneously in cooling metal alloys. [35] The lab of Cheryl Kerfeld at Michigan State University has created a synthetic nano-sized factory, based on natural ones found in bacteria. [34] Among these different testing systems, there is the Mimotope Variation Analysis (MVA) developed and patented by the Estonian biotechnology company Protobios which has never been used in the framework of biomaterial assessment before. [33] Medical physicist Dr. Aswin Hoffmann and his team from the Institute of Radiooncology-OncoRay at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have combined magnetic resonance imaging (MRI) with a proton beam, thus demonstrating for the first time that in principle, this commonly used imaging method can work with particle beam cancer treatments. [32] Washington State University researchers for the first time have shown that they can use electrical fields to gain valuable information about the tiny, floating vesicles that move around in animals and plants and are critically important to many biological functions. [31] Finding a fast and inexpensive way to detect specific strains of bacteria and viruses is critical to food safety, water quality, environmental protection and human health. [30] In the perspective, Gabor and Song collect early examples in electron metamaterials and distil emerging design strategies for electronic control from them. [29]

University of Groningen physicists have visualized hydrogen at the titanium/titanium hydride interface using a transmission electron microscope. [28] Metal oxide frameworks, or MOFs, are solid materials which can behave like ultra-fine sponges. The cavities in the sponge are of nanosize—about the size of individual molecules. [27] Now researchers in France reckon they have finally found convincing evidence for the transformation, having built new devices for pressurizing and observing tiny samples of hydrogen. [26]

An international team of researchers has found a new way to create 1-D heterostructures—by nesting nanotubes. [47] In a recently published paper in Science Advances, Feng Ding of the Center for Multidimensional Carbon Materials and colleagues have achieved the creation of a specific type of carbon nanotubes (CNTs) with a selectivity of 90 percent, and expanded the current theory that explains the synthesis of these promising nanocylinders. [46] An international team of scientists led by researchers from the Laboratory of Nanomaterials at the Skoltech Center for Photonics and Quantum Materials (CPQM) has shown that the nonlinear optical response of carbon nanotubes can be controlled by electrochemical gating.
