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 ...

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 ...

Space is tough on materials. Radiation, UV light, atomic oxygen and sharp temperature swings can degrade metals, polymers and coatings over time. This article looks at the current ways researchers are ...

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 ...

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

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 ...

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 ...
