High-Pressure Diamond Anvil Creates a New Solid from Xenon and Hydrogen

The useful noble gas may provide a breakthrough way to store hydrogen for fuel

Hydrogen Storage: Store me some hydrogen  Nature Chemistry/H-Racer
Science under pressure can produce marvelous results, such as an entirely new way to store hydrogen fuel. Researchers combined the noble gas xenon with molecular hydrogen (H2) to make a never-before-seen solid that opens the doors to an entire new family of materials for hydrogen storage.

Searching For Dark Matter In the World's Deepest Underground Lab

Will scientists find dark matter 4,850 feet below the surface of the earth? If not, maybe at 8,000 feet

Scientists at Case Western Reserve University, Brown University, and several other collaborators are building an underground science lab where, in a 300-kilogram tank filled with liquid xenon, they hope to find dark matter -- the material that scientists believe was instrumental in helping to form the universe.

The Next Space Thruster

Rockets burn for mere minutes. This engine runs for years, sending probes to Neptune at 10,000 miles an hour

NASA's Ion Engine

1. Charge the Fuel
Xenon is an inert gas, seemingly useless for rocketry. Before it´s used as fuel, the engine must convert it into an electrically charged gas, also called a plasma. An electron emitter fires electrons at the xenon gas. When an electron hits a xenon atom, it strips off an additional electron from the atom´s shell to create a positively charged xenon ion.
