The thermodynamic stability of uranium hydrides is of broad interest and fundamental importance for understanding the hydriding corrosion of uranium, and the storage and isotope separation of hydrogen. Based on the first-principles calculations, we reveal the initial decomposition mechanism, interpret the experimental pyrolysis results, and discuss the inverse effects of temperature and hydrogen pressure () on the thermodynamic stability of β-UH. The decomposition mechanism of β-UH is found to be closely related to the changes of U-H bonding properties in UH cages.

- * The study focuses on europium (Eu) and uses advanced techniques to examine its valence and structural transitions under high pressure, specifically up to 160 GPa.
- * Findings reveal a significant valence transition around 80 GPa that coincides with a structural change, which is important for understanding the properties of Eu, including its magnetism and potential for superconductivity under extreme conditions.
Equations of state and transport properties of warm dense beryllium: a quantum molecular dynamics study.
Phys Rev E Stat Nonlin Soft Matter Phys
April 2013
We have calculated the equations of state, the viscosity and self-diffusion coefficients, and electronic transport coefficients of beryllium in the warm dense regime for densities from 4.0 to 6.0 g/cm(3) and temperatures from 1.
