Like turning a snowball back into fluffy snow, a new technique turns high-density materials into a lower-density one by applying the chemical equivalent of ‘negative pressure.’
The liquid sheets – less than 100 water molecules thick – will let researchers probe chemical, physical and biological processes, and even the nature of water itself, in a way they could never do before.
The foils, each made from a single chemical element, are used to calibrate X-ray equipment at SLAC’s SSRL synchrotron, and were donated by long-time user, Farrel Lytle.
The new technology could allow next-generation instruments to explore the atomic world in ever more detail.
When it comes to making molecular movies, producing the world’s fastest X-ray pulses is only half the battle. A new technique reveals details about the timing and energy of pulses that are less than a millionth of a billionth of a second long, which can be used to probe nature’s processes at this amazingly fast attosecond timescale.
The DOE’s top official met with SLAC staff and toured the Linac Coherent Light Source X-ray laser, where a superconducting upgrade is underway.
The professor at University of California, Davis, describes his innovative work at SLAC’s synchrotron to search for simple, selective catalysts.
With X-ray imaging at SLAC’s synchrotron, scientists uncovered a 6th century translation of a book by the Greek-Roman doctor Galen. The words had been scraped off the parchment manuscript and written over with hymns in the 11th century.
Using SLAC’s X-ray laser, researchers have made detailed 3-D images of nanoscale biology, with future applications in the study of air pollution, combustion and catalytic processes.
Streamlining their journey through the electrolyte could help lithium-ion batteries charge faster.
