Normally, a material absorbs and emits heat in a linked way: A surface that absorbs heat well at a certain wavelength and ...

A newly developed material can control and "program" heat, allowing it to direct thermal radiation, switch modes, and ...

A reconfigurable device breaks the usual link between heat absorption and emission, enabling direction-controlled thermal ...

Thermal radiation is electromagnetic radiation emitted by all objects with temperature and most representatively, there is the solar radiation spectrum that enters the Earth and causes the greenhouse ...

Researchers with the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have experimentally demonstrated that metasurfaces (two-dimensional materials structured at the nanoscale) ...

Researchers have broken a centuries-old law of physics, putting us on a path towards making better energy-harvesting devices, such as solar cells. Atoms at temperatures beyond absolute zero may be a ...

NASA engineer Robert Siegel helped revolutionize heat transfer research through pioneering studies in thermal radiation, zero ...

A team of engineers and material scientists in the Paul M. Rady Department of Mechanical Engineering at CU Boulder has developed a new technology to turn thermal radiation into electricity in a way ...

This diagram illustrates the effects of applying LBSO thermal emitter to TPV technology. In the case of a typical blackbody, when it absorbs heat, it emits radiant energy over a very broad wavelength ...
