Recentely we have measured (RB 1620263) pressure dependence of phonon modes in both the protonated (H2O) and deuterated ice (D2O) (Fig. 2) at ambient, 0.3 kbar, 1.0 kbar and 1.6...

The reported structural phase transition in YMnO3 from P63cm to P63/mmc space group occurs at 1258 ±14 K. For low temperature phase (space group P63cm) the phonon modes are...

We propose to measure phonon density of states in LixFePO4 (x = 0.3, 0.6 and 1.0; three sample) from 300 to 1000 K to understand the role of lithium disorder with change in x...

We would measure vibrational spectra for Li2Si2O5 and Na2Si2O5, as well as quasielastic neutron scattering (QENS) spectra for Na2SiO5. The measurement of phonon spectra over...

The high ionic conducting delta-phase of Bi2O3 can be stabilized at ambient temperature in a range of compositions, viz., (Bi1-xYx)2O3 (x=0.1 -0.5). We would measure inelastic...

We would measure vibrational spectra as well as quasielastic neutron scattering (QENS) spectra for beta- alumina (11Al2O3-Na2O) and Na2Ti3O7. The measurement of phonon spectra...

Among the all known crystalline ice phases, ice (Ih phase) exhibits anomalous thermal expansion behavior. We propose to measure phonon density of state of protonated ice (H2O)...

The reported structural phase transition in YMnO3 from P63cm to P63/mmc space group occurs at 1258 ±14 K. For low temperature phase (space group P63cm) the phonon modes are...

We propose to measure the quasielastic neutron scattering (QENS) spectra to study the diffusion dynamics in beta- alumina (11Al2O3-Na2O) and Na2Ti3O7. The measurement of QENS...
