Twin domains in La2−xSrxCuO4 under uniaxial pressure

Using bulk-sensitive X-ray microdiffraction in Laue geometry, the distribution of twin domains in La2−xSrxCuO4 under uniaxial pressure is imaged.  It is observed that the twin domain with a shorter lattice parameter along the direction of pressure is unstable under compression and disappears completely only under moderate pressure.

Accumulation of persistent tungsten in bone

Tungstate accumulates in bone and can be resistant to chelation therapies typically used to remove heavy metals in vivo. Here, tungstate is shown to accumulate in mouse bone tissue in a persistent, insoluble form proposed to be condensed polytungstate.

Formation of conductive phase in LFP during carbon coating

A conductive phase is observed during the carbon coating process of lithium iron phosphate and the phase content is size, temperature, and annealing atmosphere dependent. The formation of this phase is related to the reducing capability of the carbon coating process.

Very sensitive Elemental and Structural Probe Employing Radiation from a Synchrotron


VESPERS is a hard X-ray microprobe beamline capable of providing a high level of complementary structural and analytical information. The techniques of X-ray diffraction and X-ray fluorescence spectroscopy are employed to analyze a microscopic volume in the sample, as well as X-ray absorption spectroscopy. Multi-bandpass and pink beam capability are built in to meet various requirements. A mm-sized beam is also available for the experiments.
