Graphene Softer if You Bend

Authors: George Rajna
Comments: 78 Pages.

To make the bent graphene, Yu fabricated individual atomic layers of hexagonal boron nitride, another 2-D material, into atomic-scale steps, then stamped the graphene over the top. [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] 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.

Cooper Pair Metal

Authors: George Rajna
Comments: 77 Pages.

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. [50] In a recent study, researchers at the NASA Ames Research Center have demonstrated that nanoscale vacuum channel transistors can be fabricated on silicon carbide wafers. [49] Titanium oxide (TiO2) nanofibers can have various applications, such as in catalyzers and filters. [48] Today, scientists report progress in making versions of these nanoparticles that could someday give built-in night vision to humans. [47] A new piece of a difficult puzzle-the nature of memory-fell into place this week with a hint at how brain cells change structure when they learn something. [46] Researchers at the University of Alberta have found an important protein in the cells of a deadly infectious parasite, opening the door to less harmful treatment for millions of people suffering from diseases like sleeping sickness in Africa and Chagas disease in South America. [45] The remarkable ability of a small Australian sea snail to produce a colourful purple compound to protect its eggs is proving even more remarkable for its potential in a new anti-cancer pharmaceutical. [44] Gene editing technology is a technology that eliminates the underlying causes of and treats diseases by removing specific genesor editing genes to restore their normal function. In particular, CRISPR gene editing technology is now commonly used for immunotherapy by correcting the genes of immune cells to induce them to attack cancer cells selectively. [43] Bioengineers and biophysicists from the have discovered that the toxicity of nanoparticles depends more on their size and the extent to which their surface area is charged than on their chemical composition.

Ultrafast Laser Pulses Produces

Authors: George Rajna
Comments: 40 Pages.

But in new experiments by physicists at MIT and elsewhere, the opposite happens: When a pattern called a charge density wave in a certain material is hit with a fast laser pulse, a whole new charge density wave is created—a highly ordered state, instead of the expected disorder. [27] Scientists from Universität Hamburg have united the two research fields and succeeded in observing the emergence of ions in ultracold atoms. [26] Researchers at the Kirchhoff Institute for Physics of Heidelberg University recently succeeded in verifying so-called non-local quantum correlations between ultracold clouds of rubidium atoms.

Metamaterials Reprogram Themselves

Authors: George Rajna
Comments: 25 Pages.

Materials scientists aim to engineer intelligence into the fabric of materials or metamaterials for programmable functions. [15] Researchers at Aalto University have developed new metasurfaces for the arbitrary manipulation of reflected waves, essentially breaking the law to engineer the reflection of a surface at will. [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]

Magnetic Anisotropy of Electric Polarization

Authors: George Rajna
Comments: 56 Pages.

Researchers at Kanazawa University controlled the magnetic properties of a metal layer through the electrical polarization of a neighboring metal oxide layer. [34] It is commonplace to be under pressure at the U.S. Department of Energy's Ames Laboratory— that is, if you happen to be a sample of material undergoing investigation by the lab's condensed matter physicists. [33] Associate Professor Justin Ye, head of the Device Physics of Complex Materials group at the University of Groningen, studied superconductivity in a double layer of molybdenum disulfide and discovered new superconducting states.

Comments: 30 Pages.

A group of scientists led by Artem Oganov of Skoltech and the Moscow Institute of Physics and Technology, and Ivan Troyan of the Institute of Crystallography of RAS has succeeded in synthesizing thorium decahydride (ThH10), a new superconducting material with the very high critical temperature of 161 kelvins. [20] Scientists at the U.S. Department of Energy's Ames Laboratory have developed a method to accurately measure the "exact edge" or onset at which a magnetic field enters a superconducting material.

Accelerating Nano-Engineering

Authors: George Rajna
Comments: 51 Pages.

Researchers from SMART, MIT's research enterprise in Singapore, have made a groundbreaking discovery that allows scientists to "look" at the surface density of dispersed nanoparticles. [31] KAIST researchers have reported the detection of a picosecond electron motion in a silicon transistor. [30] In quantum physics, some of the most interesting effects are the result of interferences. [29] When Nebraska's Herman Batelaan and colleagues recently submitted a research paper that makes the case for the existence of a non-Newtonian, quantum force, the journal asked that they place "force" firmly within quotes.

Connecting LEDs with transparent conductive circuits has made it possible to turn glass windows, walls and building exteriors into see-through displays that inform or entertain viewers with videos and images. [38] The new technology can successfully measure heart rate and oxygen saturation. It also has the potential to measure blood pressure and cardiac output, whilst maintaining its flexible and transparent form. [37] Electrical engineers at Duke University have devised a fully print-in-place technique for electronics that is gentle enough to work on delicate surfaces including paper and human skin. [36]
