A polycrystalline diamond micro-detector for X-ray absorption fine-structure measurements [PDF]

Journal of Synchrotron Radiation, 2022
The microminiaturization of detectors used to record the intensity of X-ray beams is very favorable for combined X-ray experimental techniques. In this paper, chemical-vapor-deposited (CVD) polycrystalline diamond film was used to fabricate a micro ...

Extended X-ray absorption fine structure of dynamically-compressed copper up to 1 terapascal [PDF]

Nature Communications, 2023
Large laser facilities have recently enabled material characterization at the pressures of Earth and Super-Earth cores. However, the temperature of the compressed materials has been largely unknown, or solely relied on models and simulations, due to lack

Extended X-ray absorption fine structure of bimetallic nanoparticles [PDF]

Beilstein Journal of Nanotechnology, 2011
Electronic and magnetic properties strongly depend on the structure of the material, especially on the crystal symmetry and chemical environment. In nanoparticles, the break of symmetry at the surface may yield different physical properties with respect ...
