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 ...

The ability to detect infrared radiation is the basis of any infrared thermal imaging technology. All objects emit infrared radiation as a function of their temperature; the detection of such ...

Invisible light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and optical sensing. Ultraviolet and near-infrared wavelengths are routinely ...

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 ...

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 ...

Terahertz radiation, occupying a spectral region between microwave and infrared frequencies, is increasingly recognised for its potential in applications ranging from biomedical imaging and security ...

(Nanowerk News) An international team of researchers, led by Drexel University, has found that a thin coating of MXene — a type of two-dimensional nanomaterial discovered and studied at Drexel for ...
