The second phase of a major upgrade project is now online at SLAC’S Linac Coherent Light Source (LCLS). On Saturday, scientists ushered an electron beam through a new undulator to produce “soft” X-rays (left). This follows the upgraded facility’s first...
An illustration shows polarons – fleeting distortions in a material’s atomic lattice ––in a promising next-generation energy material, lead hybrid perovskite.
As this animation shows, polaronic distortions start very small and rapidly expand outward in all directions to a diameter of about 5 billionths of a meter, which is about a 50-fold increase. This nudges about 10 layers of atoms slightly...
A battery's liquid electrolyte clings to small holes in a cryo-EM sample holder. The electrolyte will be fast-frozen into a glassy state to preserve its contents for study with the cryo-EM electron beam.
