A precious metal used everywhere from car exhaust systems to fuel cells, platinum is an incredibly efficient catalyst—but it's costly and carbon-intensive. Now, a serendipitous collaboration between ...

The discovery itself is simple and fundamental, but the applications stretch far and wide into astrophysics and quantum ...

The multicell converter topology is said to possess a natural voltage balancing property. This paper is the first of a two-part series in which multicell converters are modelled for the general case ...

The theory and implementation of a new family of monopole antennas loaded with composite right/left handed (CRLH) unit cells are presented. The proposed antennas have a number of narrow bands that is ...

Herein, for the first time a unique method, antigalvanic reduction (AGR), is introduced to synthesize atomically monodisperse Au 25 Ag 2 (SC 2 H 4 Ph) 18 in high yield (89%) within 2 min.

From there, it's transported to an HPU2 unit, the next generation of GeoPura's technology. The setup is about the size of a storage container. It uses fuel cells, not combustion, to make electricity.

In some cases, the angle criterion was met, but the cell shape did not match the expected cell shape of the polymorph III phase but was, e.g., much more elongated than the cell of the reference ...

Mr. Castillo, 36, said that the four holding cells — two for men, two for women — were so packed that some of the nearly 100 migrants in his cell resorted to sleeping on the bathroom floors.

Chinese scientists hit 24.6% efficiency with a two-terminal perovskite-CIGS tandem cell by adding D-homoserine lactone hydrochloride (D-HLH) to the perovskite precursor, marking one of the highest ...
