Combined Measure Nanostructure

Authors: George Rajna
Comments: 50 Pages.

Researchers at Leiden University and TU Delft have combined two techniques that are used to measure the structure of biomolecules, creating a method that is 10 times more sensitive. [33] The researchers hope that these predictions will now also be tested experimentally and lead to the development of new nanostructures. Such systems can make important contributions to the further miniaturisation of electronics. [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]

Dynamic Organic Plasmonics

Authors: George Rajna
Comments: 53 Pages.

Researchers in the Organic Photonics and Nano-optics goup at the Laboratory of Organic Electronics have developed optical nanoantennas made from a conducting polymer. [33] The first detection of quantum dots using this approach has been outstanding. [32] Researchers from Empa and ETH Zurich, together with colleagues from IBM Research Zurich, have recently been able to create this effect with long-range ordered nanocrystal superlattices. [31] The optical tweezer is revealing new capabilities while helping scientists understand HYPERLINK "https://phys.org/tags/quantum+mechanics/" quantum mechanics, the theory that explains nature in terms of subatomic particles. [30] In the perspective, Gabor and Song collect early examples in electron metamaterials and distil emerging design strategies for electronic control from them.

Induce Magnetism in Graphene

Authors: George Rajna
Comments: 34 Pages.

For the first time, the researchers have now succeeded in producing such a structure in practice, and showed that the theory does correspond to reality. [21] University of Groningen physicists in collaboration with a theoretical physics group from Universität Regensburg have built an optimized bilayer graphene device that displays both long spin lifetimes and electrically controllable spin-lifetime anisotropy. [20] Researchers working at coupled graphene, a monolayer form of carbon, with thin layers of magnetic materials like cobalt and nickel to produce exotic behavior in electrons that could be useful for next-generation computing applications. [19] Particles can exchange their spin, and in this way spin currents can be formed in a material. [18] Researchers have shown that certain superconductors-materials that carry electrical current with zero resistance at very low temperatures-can also carry currents of 'spin'. [17] The first known superconductor in which spin-3/2 quasiparticles form Cooper pairs has been created by physicists in the US and New Zealand. [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. [15] A group of researchers from institutions in Korea and the United States has determined how to employ a type of electron microscopy to cause regions within an iron-based superconductor to flip between superconducting and non-superconducting states. [14] In new research, scientists at the University of Minnesota used a first-of-its-kind device to demonstrate a way to control the direction of the photocurrent without deploying an electric voltage. [13] Brown University researchers have demonstrated for the first time a method of substantially changing the spatial coherence of light. [12] Researchers at the University of Central Florida have generated what is being deemed the fastest light pulse ever developed. [11]

Authors: George Rajna
Comments: 35 Pages.

Researchers of the Center for Multidimensional Carbon Materials (CMCM) within the Institute for Basic Science (IBS, South Korea) have reported in Nature Nanotechnology the first experimental observation of a chemically induced conversion of large-area bilayer graphene to the thinnest possible diamond-like material, under moderate pressure and temperature conditions. [22] For the first time, the researchers have now succeeded in producing such a structure in practice, and showed that the theory does correspond to reality. [21]

Molecular Graphenoids Spin Centers

Authors: George Rajna
Comments: 81 Pages.

This is the finding of researchers in the UK and Germany who made the dots, or “graphenoids”, using a bottom-up chemical process rather than the top-down methods usually employed to create such nanostructures. [49] The Graphene Flagship brought together top European researchers and companies to discuss the most disruptive ways graphene could enhance composites used in the aerospace, automotive and energy industries. [48] Contrary to what is believed, monolayer graphene (a sheet of carbon just one atomic layer thick) has 3D mechanical properties and they can now be properly measured and meaningfully described thanks to high-pressure Raman spectra measurements on the material.

Switches Conducting and Insulating States

Authors: George Rajna
Comments: 78 Pages.

Northwestern Engineering researchers have developed a novel design strategy to identify new materials exhibiting a metal-insulator transition (MIT), a rare class of materials categorized by their ability to reversibly switch between electrically conducting and insulating states. [44] Physicists at University of California, Riverside, have designed an experiment to explain the concept of magnetic resonance. The project was carried out by undergraduate students in collaboration with local high school teachers. [43] Magnetic reconnection, a process in which magnetic field lines tear and come back together, releasing large amounts of kinetic energy, occurs throughout the universe. [42] Plasma particle accelerators more powerful than existing machines could help probe some of the outstanding mysteries of our universe, as well as make leaps forward in cancer treatment and security scanning-all in a package that's around a thousandth of the size of current accelerators. [41] The Department of Energy's SLAC National Accelerator Laboratory has started to assemble a new facility for revolutionary accelerator technologies that could make future accelerators 100 to 1,000 times smaller and boost their capabilities. [40] The authors designed a mechanism based on the deployment of a transport barrier to confine the particles and prevent them from moving from one region of the accelerator to another. "There is strong experimental evidence that there is indeed some new physics lurking in the lepton sector," Dev said. [38] Now, in a new result unveiled today at the Neutrino 2018 conference in Heidelberg, Germany, the collaboration has announced its first results using antineutrinos, and has seen strong evidence of muon antineutrinos oscillating into electron antineutrinos over long distances, a phenomenon that has never been unambiguously observed.

High-Performance Triboelectric Materials

Authors: George Rajna
Comments: 79 Pages.

Triboelectric generation is an energy harvesting technique that generates electricity through induction of triboelectric effects using discarded physical energy.

[27] Using X-ray laser technology, a team led by researchers of the Paul Scherrer Institute PSI has recorded one of the fastest processes in biology. [26] A Virginia Commonwealth University researcher has developed a procedure for identifying the source of cells present in a forensic biological sample that could change how cell types are identified in samples across numerous industries.
