One of the central ideas in modern physics is the phase transition—a sudden transformation of the state of a material. We ...

EPFL physicists propose a new path to detect infrared radiation with outstanding sensitivity, allowing detection of signals as low as that of a single quantum of light. When using our webcam or cell ...

Infrared radiation (IR), sometimes referred to simply as infrared, is a region of the electromagnetic radiation spectrum where wavelengths range from about 700 nanometers (nm) to 1 millimeter (mm).

Most people can perceive different colours in the visible range of the electromagnetic spectrum – at wavelengths between about 400 and 700 nm. However, our eyes cannot see infrared radiation, let ...

An international team of researchers, led by Drexel University, has found that a thin coating of MXene — a type of two-dimensional nanomaterial discovered and studied at Drexel for more than a decade ...

A new infrared portrait from the James Webb Space Telescope has captured a Sun-like star in the throes of its long, ...
