By crossing two counter-rotating ultrafast laser beams in a gas target, scientists controlled the direction and polarization of laser-like beams in the extreme ultraviolet and soft x-ray portions of the spectrum. This represents a new ability to manipulate x-ray light using visible light, and obviates the need for inefficient and expensive optics that other approaches…
New Microwave Synthesis Technique Produces More-Affordable Hydrogen
Storing energy from sunlight or wind inside the bonds of a hydrogen (H2) molecule would let intermittent renewable energy power fuel cells, providing electricity on demand. The scalable production of H2, created by splitting apart water (H2O), depends on how well the catalysts drive the reaction. Thus far, platinum catalysts are the best, but the…
