Normally, an object in thermal equilibrium with its environment emits and absorbs thermal radiation at the same rate (left). But researchers have developed a multilayer material (right) that, when ...

A new adaptive metaskin hides objects from thermal cameras in both hot and cold environments, automatically adjusting its ...

For how long can the Earth support complex life before entering an irreversible zone from an environmental perspective?

With the rapid development of nanophotonics, spectrally selective infrared stealth technology has achieved great success through the design of metamaterials. However, as the background environment is ...

Prof Zhang Zhiyong's team at Peking University developed a heterojunction-gated field-effect transistor (HGFET) that achieves high sensitivity in short-wave infrared detection, with a recorded ...

An international team of researchers has found that a thin coating of MXene -- a type of two-dimensional nanomaterial -- could enhance a material's ability to trap or shed heat. The discovery, which ...

The observations are of fundamental importance for electrodynamics and will provide researchers with an entirely new method of absorbing the energy of electromagnetic waves MOSCOW, December 17. /TASS/ ...

With today's data rates of only a few hundred megabytes per second, access to digital information remains relatively slow. Initial experiments have already shown a promising new strategy: Magnetic ...

An incandescent lighting device that reuses some of the infrared light it emits could be as efficient as an LED light but contribute less to carbon emissions. Lighting accounts for about 20 per cent ...
