Erasable semiconductor is programmed with light

Researchers at Princeton Engineering have created a semiconductor with unique properties: It is just a few molecules thick and can repeatedly change its properties in response to light. This is a step toward building more ...

New flow sensor can measure hydrogen in pipes of any size

Until now, it has been almost impossible to measure the energy density of hydrogen precisely, but a new sensor can register every single molecule. This could lay the foundation for correct accounting in the hydrogen economy.

Nonmetallic metasurfaces offer a new way to block radiant heat

Researchers at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) and Honeywell Aerospace have developed a new way to reduce the transfer of radiant heat between closely spaced bodies by using thin, ...

Like a bird, this drone uses touch to grip branches and rest

Drones often hover in the air, noisy and whining. They can already be used for many tasks, but not when you need some quiet. Their batteries would also last longer if they could take a "rest" from time to time. But when a ...
