About 60 years ago, scientists discovered that a certain rare earth metal-hydrogen mixture, yttrium, could be the ideal moderator to go inside small, gas-cooled nuclear reactors. But there wasn't a ...

Separating gases such as hydrogen from larger compounds in the air is an important part of manufacturing and energy production. But it's also an expensive process, requiring large amounts of energy ...

Metal hydrides are considered a cutting-edge storage material for hydrogen. These hydrides function even better, if the micrometer-sized hydride particles are coated with a thin polymer film. Using a ...
