Microcrystal electron diffractometer brings hidden hydrogen into focus

Hydrogen—the lightest atom—does the heavy lifting when it comes to important chemical reactions. It can be stored and released as clean fuel, and its movements help catalysts build medicines, fertilizers and materials. One way hydrogen is available for use is through a hydride—a hydrogen (H) atom bound to a metal. Yet with standard tools, this metal-bound atom can be hard to find in the structure.
