The online magazine Physics World has awarded the research team of Pablo Jarillo-Herrero, a researcher of the MIT, for making a discovery that led to the development of “twistronics”. This promising technique can adjust the electronic properties of graphene by rotation of its adjacent layers. Their first achievement was the creation of magic-angle graphene, which behaves like a high temperature semiconductor.

High-entropy alloys (HEAs), which are formed by combining nearly equal parts of several – usually five or more – primary metals, are an emerging class of advanced materials that hold great potential for creating materials with superior mechanical, thermal, and catalytic properties. Another attraction of HEAs is that they can create effective alternatives to materials that are scarce, hazardous, expensive, or subject to international restrictions or conflict.Lire la suite
Biosensors integrated into smartphones, smart watches, and other gadgets are about to become a reality. In a paper featured on the cover of the January issue of Sensors (« Vertically Coupled Plasmonic Racetrack Ring Resonator for Biosensor Applications »), researchers from the Moscow Institute of Physics and Technology describe a way to increase the sensitivity of biological detectors to the point where they can be used in mobile and wearable devices. The study was supported by the Russian Science Foundation.Lire la suite
