New nanoparticle source generates high-frequency light

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see.

Manipulating hypersound in mesoporous materials

The rapidly advancing field of nanophononics focuses on the study of hypersound, which are acoustic waves in the gigahertz to terahertz range, at the nanoscale. These high-frequency acoustic vibrations, also known as acoustic ...

A new type of photonic time crystal gives light a boost

Researchers have developed a way to create photonic time crystals, and they have shown that these bizarre, artificial materials amplify the light that shines on them. These findings, described in a paper in Science Advances, ...
