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

Near-field radiative heat transfer The ability to precisely control how heat flows could lead to new cooling strategies for ...

Scientists have created a programmable material that gives engineers unprecedented control over heat, with potential ...

Researchers have developed a new technology that uses meta-optical devices to perform thermal imaging. The approach provides richer information about imaged objects, which could broaden the use of ...

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) ...

For more than 160 years, engineers building anything that generates or manages heat have worked under a rule so reliable it might as well have been gravity: whatever surface absorbs infrared radiation ...

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

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 ...

Two researchers stand and talk in a laboratory, the person on the left is holding a white fabric square. The University of Chicago’s Chenxi Sui (left) and Po-Chun Hsu have developed radiative cooling ...

Original equipment manufacturers (OEMs) in the industrial heating and lighting sectors frequently encounter a frustrating operational challenge: quartz heating envelopes that degrade prematurely.
