A team of researchers from Russia, Great Britain, Japan, and Italy has created a graphene-based terahertz detector. The study was published in Nature Communications. Any system for wireless data transfer relies on electromagnetic wave sources and detectors, but they are not available for every kind of waves. The existing sources of terahertz radiation, which occupies a…
X-Ray Pulsars Fade as Propeller Effect Sets In
An international team of astrophysicists including Russian scientists from the Space Research Institute of the Russian Academy of Sciences (RAS), MIPT, and Pulkovo Observatory of RAS has detected an abrupt decrease of pulsar luminosity following giant outbursts. The phenomenon is associated with the so-called “propeller effect,” which was predicted more than 40 years ago. However,…
Diamond-based Resonators Might Become Highly Sensitive Detectors
Physicists from the Technological Institute for Superhard and Novel Carbon Materials, the Moscow Institute of Physics and Technology, and the Siberian Federal University have mathematically modelled diamond-based microstructures for producing compact high sensitivity sensors. The researchers’ study investigates the problem of selecting a useful acoustic signal taking into account the excitation of Lamb waves in…
