So we know why we want to detect hydrogen.

Being able to detect hydrogen would be a handy backup to placing temperature sensors on at-risk pieces of zircaloy-clad equipment.

Semiconductor sensors are commonly used to detect hydrogen, oxygen, alcohol, and harmful gases such as carbon monoxide.

This allows radio astronomers to detect hydrogen, the most abundant element of the Universe.

Researchers noted that the $65 million spacecraft's instruments actually detected hydrogen, the element that combines with oxygen to make water.

The Air Force has begun detecting corrosion with a $25.9 million system that bombards a plane with neutrons to detect hydrogen, a byproduct of corrosion.

The measurements can detect hydrogen only about a yard below the surface.

Initial failure to detect hydrogen or helium led to SN 1994I being classified as a Type Ic.

The extreme ultraviolet power was only a few watts, but it was adequate to detect molecular hydrogen.

Other scientists have recently reported methods of detecting hydrogen and methane in extraterrestrial atmospheres.
