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
In a critical step toward creating a global quantum communications network, researchers have generated and detected quantum entanglement onboard a CubeSat nanosatellite weighing less than 2.6 kilograms and orbiting the Earth. “In the future, our system could be part of a global quantum network transmitting quantum signals to receivers on Earth or on other spacecraft,” […] More
