Pressure-Induced Irreversible Disorder in $β^{\prime}$-Mn(PO): A High-Pressure X-ray Diffraction and Density-Functional Theory Study
Ana Melissa P. Brito, Neha Bura, Pablo Botella +7
The high-pressure structural behavior of $β^\prime$-Mn(PO) was investigated using synchrotron X-ray diffraction up to 20 GPa combined with density-functional theory ca…
High-Pressure Structural Evolution of Na2ZrSi2O7 and Na2ZrSi2O7.H2O: Topology-Driven Compression Behaviors, Phase Stability, and Electronic Transitions
Peijie Zhang, Pablo Botella, Neha Bura +6
Silicate frameworks exhibit diverse structural responses under extreme conditions, which are strongly influenced by hydration. Here, we present a comparative high-pressure synchrot…
Comparative high-pressure study on rare-earth entropy fluorite-type oxides
Pablo Botellaa, David Vie, Leda Kolarek +6
We report a comparative high-pressure study of two fluorite-type rare-earth oxides with increasing configurational entropy, (CePr)O and (CePrLa)O. Synchrotron-bas…
High-Pressure X-Ray Diffraction Study of Scheelite-type Perrhenates
Neha Bura, Pablo Botella, Catalin Popescu +7
The effects of pressure on the crystal structure of scheelite-type perrhenates were studied using synchrotron powder X-ray diffraction and density-functional theory. At ambient con…
