At first glance, these findings appear to violate Kirchhoff's law of thermal radiation, which states that—under specific conditions—an object will absorb infrared light (absorptivity) in one direction ...

A faint flash of infrared light in the Andromeda galaxy was emitted at the birth of a stellar-mass black hole – according to a team of astronomers in the US. Kishalay De at Columbia University and the ...

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 ...

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 ...

Scientists have discovered a potentially promising infrared LED and infrared detector component. This compound -- composed of calcium, silicon and oxygen -- is cheap to produce and non-toxic. Many of ...

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 ...
