(PhysOrg.com) -- By replacing catalysts made of expensive noble metals like platinum with cheaper, earth-abundant materials, researchers have taken a step toward enabling the large-scale production of hydrogen from sunlight ...
Caltech scientists, inspired by a chemical process found in leaves, have developed an electrically conductive film that could help pave the way for devices capable of harnessing sunlight to split water into hydrogen fuel.

It all comes down to one tiny spot on a diamond-cut, highly pure copper plate. That's where every X-ray laser pulse at SLAC's Linac Coherent Light Source gets its start. That tiny spot must be close to perfect or it can impair ...
