A new metasurface design greatly improves light emission in atomically thin materials, offering a path to low-power, flexible, high-brightness display technologies. But there’s a problem: even though ...

A decade-long journey from laboratory discovery to clinical-ready technology has reached a significant milestone with the ...

van der Waals materials (vdWMs) have garnered increasing attention from both academia and industry due to their atomic-scale thickness, mechanical flexibility, and superior electrical and ...

FIG. 1 (a) Functional diagram and (b) Structure diagram of the device. Vortex beams with helical phase wavefronts can carry orbital angular momentum (OAM) and have promising applications in ...

Researchers invent nano-clouds that can change colour, temperature and outwit heat sensors. (Nanowerk News) How does a cloud stay cool under direct sunlight –– or seem to vanish in infrared? In nature ...
