Carbon nanotube-based film achieves record-low thermal conductivity at extreme temperatures, offering ultralight, scalable ...

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 ...

Thermal cameras can cost well into the five-figure range if you’re buying high-resolution models with good feature sets. New models can be so advanced that their export and use is heavily con… ...

Electromagnetic radiation with a wavelength longer than about 700 nanometers won’t activate rhodopsin, and IR generated from body heat is around 9,300 nm. In fact, no known protein is activated by ...

A research team at Penn State has reported a significant violation of Kirchhoff’s law of thermal radiation, a principle that has been a foundation of thermal physics for 165 years.

(Image: Adam Overvig) Thermal radiation — a form of electromagnetic waves generated by heat-driven random fluctuations in matter— is inherently broadband in nature, consisting of many colors. A good ...

All objects that have temperature release thermal radiation, which is electromagnetic radiation. The solar radiation spectrum is the most representative type of thermal radiation since it enters the ...

Heat-seeking missiles are designed to follow intense heat signatures, yet they don't always hit. Here's what happens when one ...

Thermal radiation — a form of electromagnetic waves generated by heat-driven random fluctuations in matter— is inherently broadband in nature, consisting of many colors.

Normally, thermal radiation is a product of randomness, described by the laws of statistical physics. TU Wien and the University of Manchester show that it can also be controlled.
