Extreme conditions in semiconductors

Researchers from the Universities of Konstanz and Paderborn have successfully demonstrated Wannier-Stark localization in a high-purity gallium arsenide crystal. This state results in drastic changes to the electronic structure of the crystal, leading to extreme optical nonlinearity and potential chemical reactivity.

Thermal camouflage disguises hot and cold

A new thermal camouflage system has been developed by researchers, allowing it to rapidly adapt to different temperatures and become indistinguishable from its surroundings. The system, which contains layers of graphene and an ionic liquid, can be applied to a variety of surfaces and is thin, light, and flexible.

Scientists create continuously emitting microlasers with nanoparticle-coated beads

Researchers have found a way to convert nanoparticle-coated microscopic beads into lasers smaller than red blood cells. These microlasers can constantly and stably emit light for hours at a time, even when submerged in biological fluids. The innovation opens up the possibility for imaging or controlling biological activity with infrare...

Discovery in the sky with nanodiamonds

A team of researchers at Cardiff University has discovered that tiny crystals of carbon, nanodiamonds, are likely the source of a mysterious microwave glow emanating from star systems in the Milky Way. The discovery was made by studying infrared light from protoplanetary disks surrounding newly formed stars.
