Scientists discover why silver clusters emit light

Clusters of silver atoms captured in zeolites, a porous material with small channels and voids, have remarkable light-emitting properties. They can be used for more efficient lighting applications as a substitute for LED ...

High efficient solar water heating achieved with nanoparticles

A research team in Japan discovered through numerical calculations that nanoparticles of transition metal nitrides and carbides absorb sunlight very efficiently, and confirmed experimentally that nitride nanoparticles, when ...

How does order emerge?

German scientists from the MPQ, LMU, and the FUB analyze how fast order can appear in a quantum-mechanical system.

Green photon beams more agile than optical tweezers

Romanian scientists have discovered a novel approach for the optical manipulation of macromolecules and biological cells. Their findings, published in the European Physical Journal B, stem from challenging the idea that visible ...

Supercomputer boosted with graphic processors

With "Piz Daint" the Swiss National Supercomputing Centre (CSCS) is putting a new supercomputer system in operation that will provide the necessary compute performance and consume less power. This is made possible by a novel ...

Study may lead to less expensive consumer lasers and LEDs

(Phys.org) -- A recent theoretical study by a University of Waterloo doctoral candidate in nanotechnology engineering suggests that manufacturers may one day make lasers and LEDs out of silicon, with the potential to significantly ...

Study on swirls to optimize contacts between fluids

Physicists who have studied the mixing between two incompatible fluids have found that it is possible to control the undercurrents of one circulating fluid to optimise its exposure to the other. This work, which is about ...
