Pushing gold exploration to the nanoscale, scientists used SLAC's Linac Coherent Light Source X-ray laser to produce a series of 3-D images that detail a ringing effect in tiny gold crystals. The technique provides a unique window for studying why smaller is better for some specialized materials, including those used in chemical reactions and electronic components, for example.
Menlo Park, Calif. — Researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life battery that could enable solar and wind energy to become major suppliers to the electrical grid.
Stephanie Mack, 20, read and reread the email in disbelief. After spending time during the past two summers in a science internship program at SLAC National Accelerator Laboratory, she was heading back.
This time she would be at the helm of the world's most powerful X-ray laser, leading an international collaboration as the principal investigator in an experiment exploring how to precisely control the motion of electrons in specially prepared samples of a mineral called manganite.
Using laser light to read and write magnetic data by quickly flipping tiny magnetic domains could help keep pace with the demand for faster computing devices.
Now experiments with SLAC's Linac Coherent Light Source (LCLS) X-ray laser have given scientists their first detailed look at how light controls the first trillionth of a second of this process, known as all-optical magnetic switching.
A material that could enable faster memory chips and more efficient batteries can switch between high and low ionic conductivity states much faster than previously thought, SLAC and Stanford researchers have determined. The key is to use extremely small chunks of it.
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. But the fastest steps in this energy transfer have eluded detection.
Menlo Park, Calif. — Researchers using the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory have found a way to strip most of the electrons from xenon atoms, creating a “supercharged,” strongly positive state at energies previously thought too low.
