SLAC study of tiny nanocrystals provides new insight on the design and function of nanomaterials
Image - In this illustration, intense X-rays produced at SLAC's Linac Coherent Light Source strike nanowires to study an ultrafast "breathing" response in the crystals induced quadrillionths of a second earlier by pulses of optical laser light.

Developed at SLAC’s LCLS, it could also yield new information from hard-to-study samples in materials science, chemistry and other fields.
Image - These charts show (a) the energy profile of two electron bunches that are separated by about 6 picoseconds, which are later stimulated to emit (b) two X-ray pulses separated by femtoseconds.

An experiment at SLAC provided the first fleeting glimpse of the atomic structure of a material as it entered a state resembling room-temperature superconductivity – a long-sought phenomenon in which materials might conduct electricity with 100 percent efficiency under everyday conditions.
Image - In a high-temperature superconducting material known as YBCO, light from a laser causes oxygen atoms to vibrate between layers of copper oxide in a way that favors superconductivity.
