Comparative study of the high-pressure behavior of ZnV2O6, Zn2V2O7, and Zn3V2O8
D. Diaz-Anichtchenko, D. Santamaria-Perez, T. Marqueno +7
We report a study of the high-pressure structural behavior of ZnV2O6, Zn2V2O7, and Zn3V2O8, which has been explored by means of synchrotron powder x-ray diffraction. We found that…
Soft Anharmonic Coupled Vibrations of Li and SiO4 Enable Li-ion Diffusion in Amorphous Li2Si2O5
Sajan Kumar, Mayanak K. Gupta, Prabhatasree Goel +7
We present the investigations on atomic dynamics and Li+ diffusion in crystalline and amorphous Li2Si2O5 using quasielastic (QENS) and inelastic neutron scattering (INS) studies su…
Sodium Diffusion and Dynamics in Na2Ti3O7: Neutron Scattering and Ab-initio Simulations
Ranjan Mittal, Sajan Kumar, Mayanak K. Gupta +7
We have performed quasielastic and inelastic neutron scattering (QENS and INS) measurements from 300 K to 1173 K to investigate the Na-diffusion and underlying host dynamics in Na2…
Stoichiometric Tuning of Lattice Flexibility and Na Diffusion in NaAlSiO4: Quasielastic Neutron Scattering Experiment and Ab-initio Molecular Dynamics Simulations
Mayanak K. Gupta, Ranjan Mittal, Sajan Kumar +7
We have performed quasielastic neutron scattering (QENS) experiments up to 1243 K and ab-initio molecular dynamics (AIMD) simulations to investigate the Na diffusion in various pha…
Phonons and Lithium diffusion in LiAlO
Mayanak K. Gupta, Ranjan Mittal, Baltej Singh +5
We report on investigations of phonons and lithium diffusion in LiAlO based on inelastic neutron scattering (INS) measurements of the phonon density of states (DOS) in γ-LiAlO$…
Dynamics of Na Ion in the Amorphous Na2Si2O5 Using Quasielastic Neutron Scattering and Molecular Dynamics Simulations
Mayanak K. Gupta, Sanjay K. Mishra, Ranjan Mittal +7
We have investigated the dynamics of Na ions in amorphous Na2Si2O5, a potential solid electrolyte material for Na-battery. We have employed quasielastic neutron scattering (QENS) t…
