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 ...

Thermal radiation: Usually it depens only on the temperature (coal on the left), But with topological tricks, it is possible to make a surface emit thermal radiation only at certain points, so that a ...

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 ...

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 ...

Passive thermal control relies on design features and materials like insulation layers, reflective coatings, and thermal barriers. Because passive solutions have no moving parts, they require less ...

In the 1930s, primitive devices were invented to capture heat and make all heated objects visible in the dark. Almost 100 years later, these devices became modern thermal imagers, which have become ...
