Seeing light emerge from a nanoscale experiment didn’t come as a big surprise to Rice University physicists. But it got their attention when that light was 10,000 times brighter than they expected. Condensed matter physicist Doug Natelson and his colleagues at Rice and the University of Colorado Boulder discovered this massive emission from a nanoscale […] More
A University of Wollongong team has published an extensive review of spin-gapless semiconductors (SGSs) . Spin gapless semiconductors (SGSs) are a new class of zero gap materials which have fully spin polarised electrons and holes. The study tightens the search for materials that would allow for ultra-fast, ultra-low energy ‘spintronic’ electronics with no wasted dissipation […] More
The brain analyses spoken language by recognising syllables. Scientists from the University of Geneva (UNIGE) and the Evolving Language National Centre for Competence in Research (NCCR) have designed a computational model that reproduces the complex mechanism employed by the central nervous system to perform this operation. The model, which brings together two independent theoretical frameworks, […] More
Indium nitride is a promising material for use in electronics, but difficult to manufacture. Scientists at Linköping University, Sweden, have developed a new molecule that can be used to create high-quality indium nitride, making it possible to use it in, for example, high-frequency electronics. The results have been published in Chemistry of Materials. The bandwidth […] More
As high school students see in experiments with water waves, and we observe and use with light waves in many optical devices, interference is a fundamental property associated with wave-like behavior. Indeed, Davisson and Germer’s famous observation of interference in experiments with dilute beams of electrons, nearly a century ago, gave key experimental support to […] More
A new study shows that the central bank tool known as quantitative easing helped consumers substantially during the last big economic downturn — a finding with clear relevance for today’s pandemic-hit economy. More specifically, the study finds that one particular form of quantitative easing — in which the U.S. Federal Reserve purchased massive amounts of […] More
The discovery of carbon nanostructures like two-dimensional graphene and soccer ball-shaped buckyballs helped to launch a nanotechnology revolution. In recent years, researchers from Brown University and elsewhere have shown that boron, carbon’s neighbor on the periodic table, can make interesting nanostructures too, including two-dimensional borophene and a buckyball-like hollow cage structure called borospherene. Now, researchers […] More
Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for example in the automotive industry, because a laser operates with virtually no wear, is very fast and offers high precision. But until now, the quality of a weld seam could only be documented […] More
