A comparative study of the high-pressure structural stability of zirconolite materials for nuclear waste immobilisation
Daniel Errandonea, Robin Turnbull, Josu Sanchez-Martin +8
We present a comparative study of the high-pressure behaviours of the nuclear waste immobilisation materials zirconolite-2M, -4M, -3O, and -3T. The materials are studied under high…
Pressure-Induced Decomposition of beta-SnWO4
Sergio Ferrari, Daniel Diaz-Anichtchenko, Pablo Botella +6
This study reports the decomposition of beta-SnWO4 into Sn, SnO2, and WO3 induced by static compression. We performed high-pressure synchrotron powder angle-dispersive X-ray diffra…
Identification of the high-pressure phases of alpha-SnWO4 combining x-ray diffraction and crystal structure prediction
Daniel Diaz-Anichtchenko, Jordi Ibáñez, Pablo Botella +7
We have characterized the high-pressure behavior of alpha-SnWO4. The compound has been studied up to 30 GPa using a diamond-anvil cell and synchrotron powder X-ray diffraction. We…
Femtosecond temperature measurements of laser-shocked copper deduced from the intensity of the x-ray thermal diffuse scattering
J. S. Wark, D. J. Peake, T. Stevens +122
We present 50-fs, single-shot measurements of the x-ray thermal diffuse scattering (TDS) from copper foils that have been shocked via nanosecond laser-ablation up to pressures abov…
