Solvent-free, catalyst-free way to produce alkali metal hydrides

Researchers at the U.S. Department of Energy's Ames Laboratory have found a way to create alkali metal hydrides without the use of solvents or catalysts.  The process, using room temperature mechanical ball milling, provides ...

Detecting caesium with naked eyes

Radioactive caesium 137 has a half-life of 30.17 years, and its accumulation in organisms in exposed regions, such as around the Fukushima Daiichi nuclear plant, amplifies the hazard it poses. A new material reported by researchers ...

Researchers tune the speed of chirality switching

Chiral molecules can have dramatically different functional properties while sharing identical chemical formulae and almost identical structures. The molecular structure of two types of a chiral molecule—so-called enantiomers—are ...

Innovative catalysts examined in expert review

Green hydrogen is an important component in a climate-neutral energy system. It is produced by electrolytically splitting water with wind or solar power and stores this energy in chemical form. But currently, the production ...

Fluorescent label sheds light on radioactive contamination

Researchers in Japan have developed a way to detect caesium contamination on a scale of millimetres enabling the detection of small areas of radioactive contamination. The research is published in Science and Technology of ...

Unleashing perovskites' potential for solar cells

Perovskites—a broad category of compounds that share a certain crystal structure—have attracted a great deal of attention as potential new solar-cell materials because of their low cost, flexibility, and relatively easy ...
