Daniel DePonte, a pioneer in finding ways to serve up a steady and precise supply of crystals, viruses and other precious samples for laser experiments, is the newly hired sample-delivery group leader for SLAC’s Linac Coherent Light Source X-ray laser.

The way electrons move within and between molecules, transferring energy as they go, plays an important role in many chemical and biological processes, such as the conversion of sunlight to energy in photosynthesis and solar cells

'Self-seeding' promises to speed discoveries, add new scientific capabilities

A surprising atomic-scale wiggle underlies the way a special class of materials reacts to light, according to research that may lead to new devices for harvesting solar energy.

Scientists have found a way to distort the atomic arrangement and change the magnetic properties of an important class of electronic materials with ultra-short pulses of terahertz (mid-infrared) laser light without heating the material up.
