These inexpensive photosensitizers could make solar power and chemical manufacturing more efficient. Experiments at SLAC offer insight into how they work.
Scientists have engineered a cheap, abundant alternative to the expensive platinum catalyst and coupled it with a light-absorbing electrode to make hydrogen fuel from sunlight and water.
The results, which show that ultrafast atomic motions are the first step in forming a magnetic state, could lead to faster and more efficient data storage devices.
Scientists use a series of magnets to transform an electron bunch into a narrow current spike which then produces a very intense attosecond X-ray flash.
Light-driven reactions are at the heart of human vision, photosynthesis and solar power generation. Seeing the very first step opens the door to observing chemical bonds forming and breaking.
An LCLS imaging technique reveals how a mosquito-borne bacterium deploys a toxin to kill mosquito larvae. Scientists hope to harness it to fight disease.
