When cooled to its superconducting state, niobium blocks the radiative flow of heat 20 times better than when in its metallic state, according to a study led by a University of Michigan Engineering ...

A Penn State team has shattered Kirchhoff’s 165-year-old law of thermal radiation. Their engineered metamaterial emits more ...

A thermal metasurface is made of a single layer of nanostructured silicon (gray) on top of glass (blue) and a metal mirror (gold). The nanostructured surface is specifically tailored so that it ...

The study of nonreciprocal thermal radiation in Weyl semimetals has emerged as a captivating field that challenges conventional understandings of thermal emission obeying Kirchhoff’s law. In these ...

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 ...

HOUSTON – (Dec. 10, 2024) – A team of Rice University scientists has solved a long-standing problem in thermal imaging, making it possible to capture clear images of objects through hot windows.

A new method to measure the continuous spectrum of light is set to improve thermal imaging and infrared thermography. A new method to measure the continuous spectrum of light, developed in the lab of ...
