Recent progress in high pressure X-ray absorption spectroscopy studies at the ODE beamline. Issue 1 (2nd January 2020) - Nataf, Lucie
ABSTRACT: High pressure energy-dispersive X-ray absorption spectroscopy is a valuable structural technique, especially, when combined with a nano-polycrystalline diamond anvil cell. Here we present recent results obtained using the dispersive setup of the ODE beamline at SOLEIL synchrotron. The effect of pressure and temperature on the X-ray induced photoreduction is discussed on the example of nanocrystalline CuO. The possibility to follow local environment changes during pressure-induced phase transitions is demonstrated for α -MoO 3 based on the reverse Monte Carlo simulations.
