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…
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…
Enhanced radiation tolerance of YSZ at high temperature against swift heavy ions: key role of interplay between material microstructure and irradiation temperature
Parswajit Kalita, Santanu Ghosh, Udai B. Singh +6
Yttria stabilized Zirconia (YSZ) pellets with different crystallite sizes were irradiated with 80 MeV Ag ions at room temperature and 1000 K to understand the role of crysta…
Pressure impact on the stability and distortion of the crystal structure of CeScO3
Daniel Errandonea, David Santamaria-Perez, Domingo Martinez-Garcia +5
The effects of high pressure on the crystal structure of orthorhombic (Pnma) perovskite type cerium scandate have been studied in situ under high pressure by means of synchrotron x…
