Short Wave New discoveries, everyday mysteries, and the science behind the headlines — in just under 15 minutes. It's science for everyone, using a lot of creativity and a little humor.

Short-wave infrared radiation (SWIR) is roughly the part of the electromagnetic spectrum between 1.4 μm – 3 μm, or 100 THz – 214 THz. This places it between visible light and microwaves ...

To him it means Liberty and Truth. This autumn, amid the happy local noise of a new U.S. radio season, the man at the other end of U.S. short-wave transmission was much on the minds of U.S ...

S. toyed with the notion of setting up a Federal short-wave station, abandoned the idea when private broadcasters, led by NBC, clamored for a chance to take Latin America by the ears. Since then ...

Current laser technologies for the extended short-wave infrared (SWIR) spectral range rely on expensive and complex materials, limiting their scalability and affordability. To address these challenges ...

The researchers used PbS (lead sulfide) quantum dots, the first semiconductor material to produce laser light over such a ...

Researchers have developed a new laser technology using large colloidal quantum dots of lead sulfide to emit coherent light in the extended short-wave infrared range. This innovation promises cheaper, ...
