Infrared (IR) light is invisible to humans. However, some animals, such as rattlesnakes or bloodsucking bats, can perceive IR radiation and use it to find food. But even for humans, the ability to see ...

infrared light but our television sets can as we happily surf through reality shows, sitcoms and sports. Infrared has forged a distinct niche in our lifestyle. It’s as much a tool as X-rays in the ...

As great as cameras that operate in the visual light spectrum are, they omit a lot of the information that can be gleaned from other wavelengths. There is also the minor issue that visibility is often ...

Materials scientists are often inspired by nature and therefore use biological compounds as cues to design advanced materials. It is possible to mimic the molecular structure and functional motifs in ...

Peking University, December 3rd, 2024: Prof Zhang Zhiyong’s team developed a heterojunction-gated field-effect transistor (HGFET) that achieves high sensitivity in short-wave infrared detection, with ...

Original equipment manufacturers (OEMs) in the industrial heating and lighting sectors frequently encounter a frustrating operational challenge: quartz heating envelopes that degrade prematurely.

"The most realistic applications are noncontact diagnostics and advanced thermal imaging," the team noted. "Different tissues ...

New ultrafast method for controlling magnetic materials might enable next-generation information processing technologies. This illustration shows that a pair of intense THz laser pulses drives spin ...
