X-ray Diffraction and Electrical Transport Imaging of Superconducting Superhydride (La,Y)H10
Abdul Haseeb Manayil Marathamkottil, Kui Wang, Nilesh P. Salke +9
We report the synthesis and characterization of (La0.9Y0.1)H10 superhydrides exhibiting coexisting cubic Fm-3m and hexagonal P63/mmc clathrate phases observed over the pressure ran…
Enhancement of hydrogen absorption and hypervalent metal hydride formation in lanthanum using cryogenic ball milling
Sakun Duwal, Vitalie Stavila, Catalin Spataru +11
Rare earth superhydrides exhibit high temperature superconductivity but are difficult to characterize and use in applications due to their high formation and stability pressures, w…
Grain growth phenomenon during pressure-induced phase transformations at room temperature
Valery I. Levitas, Raghunandan Pratoori, Dmitry Popov +2
Significant grain growth is observed during the high-pressure phase transformations (PTs) at room temperature within an hour for various materials. However, no existing theory expl…
Quantitative kinetic rules for plastic strain-induced - phase transformation in Zr under high pressure
Achyut Dhar, Valery I. Levitas, K. K. Pandey +3
Plastic strain-induced phase transformations (PTs) and chemical reactions under high pressure are broadly spread in modern technologies, friction and wear, geophysics, and astrogeo…
