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 ...
Black holes are often described as cosmic traps from which nothing can escape, yet modern physics says they are not perfectly black. At their edges, quantum effects make them glow with a faint thermal ...
For centuries, mankind's greatest technological leaps have begun with a simple act: observing nature. Our desire to fly high was inspired by birds' ability to soar the skies. Our fascination with ...
