Behavior of actinide dioxides under pressure: U O 2 and Th O 2
TL;DR: In this paper, the structural high-pressure properties of thorium and uranium dioxides have been studied in diamond-anvil cells up to maximum pressures of 80 and 69 GPa, respectively.

TL;DR: In this paper, the high-pressure structural behavior of lanthanum monochalcogenides is investigated by theory and experiment, which comprises density-functional calculations of LaS, LaSe, and LaTe with the general gradient approximation for exchange and correlation effects, as implemented within the fullpotential linear muffin-tin orbital method.

Pressure-induced changes in protactinium metal: Importance to actinide-metal bonding concepts
TL;DR: In this article, it was shown that the tetragonal structure of protactinium (space group $I4/mm) converts to an orthorhombic, alpha-uranium structure (Space group Cmcm) at 77(5) GPa, where the atomic volume has been reduced by 30%.

High-pressure x-ray diffraction study of UxLa1−xS solid solution
TL;DR: X-ray diffraction measurements under pressure have been performed on seven different compositions in the UxLa1−xS system (x = 0, 0.08,0.40, 0.,50, 0, 60, 80, 90 GPa) and in the transition pressure (~30 GPa for low-uranium-content compounds and from 45 to 80 GPa with high concentrations as mentioned in this paper.

High-pressure crystal structures of actinide elements to 100 GPa
TL;DR: In this article, the structural properties of actinide metals with pressure were studied using diamond-anvil cells and the high-brilliance and angle-dispersive techniques available at the ID30 beamline of the European Synchrotron Radiation Facility.
