This Study Is to Investigate the Crystallization, Chemistry and Structure Arising From Complex Interfaces of Quantum Mixtures (QM: Mixtures of H2, He and Other Light Molecules Such as C, N2, O2, CO2, and H2O) Under High Pressure-temperature (PT) Conditions and Gain Fundamental Insights Into Novel Pressure-regulated Crystallization of QM, Unusual Chemical Reaction in Inert QM, and Novel Conducting States and Phase Behaviors of Quantum Fluids Mixtures (QFM). the Emphasis of the Proposed Research Will Be on Probing Time-evolution of Chemical Bonding and Metastable Structures of Highly Diffusive Quantum Interfaces, Utilizing State of the Art Dynamic-diamond Anvil Cell (d-dac) and Dynamic Precompression Experiments, Coupled With Time-resolved Raman Spectroscopy, High-speed Microscopy, and Time-resolved X-ray Diffraction at Advanced 3RD and 4TH Generation Light Sources. the Present Work Will Also Develop High PT Technologies Needed for Fundamental Research in Nnsa’s SSP, Generate Fundamental Data and Knowledge That Will Benefit Nnsa’s Psaap, and Provide Exceptional Education and Training Opportunities for Graduate Students for Future Workforce at the Nnsa Laboratories.
