Impact of chemical structure on the dynamics of mass transfer of water in conjugated microporous polymers: A neutron spectroscopy study
Anne A. Y. Guilbert, Yang Bai, Catherine M. Aitchison +2
Hydrogen fuel can contribute as a masterpiece in conceiving a robust carbon-free economic puzzle if cleaner methods to produce hydrogen become technically efficient and economicall…
Spin-Phonon Coupling, High Pressure Phase Transitions and Thermal Expansion of Multiferroic GaFeO3: A Combined First Principles and Inelastic Neutron Scattering Study
M. K. Gupta, R. Mittal, M. Zbiri +4
We have carried out an extensive phonon study on multiferroic GaFeO3 to elucidate its dynamical behavior. Inelastic neutron scattering measurements are performed over a wide temper…
Phonon Dynamics and Inelastic Neutron Scattering of Sodium Niobate
S. K. Mishra, M. K. Gupta, R. Mittal +4
Sodium niobate (NaNbO3) exhibits most complex sequence of structural phase transitions in perovskite family and therefore provides as excellent model system for understanding the m…
Phase Stability of Multiferroic GaFeO3 up to 1368 K from In situ Neutron Diffraction
S. K. Mishra, R. Mittal, R. Singh +3
We report a detailed high-temperature powder neutron diffraction investigation of the structural behavior of the multiferroic GaFeO3 between 296 and 1368 K. Temperature dependent n…
High-Temperature Phonon Spectra of Multiferroic BiFeO3 from Inelastic Neutron Spectroscopy
M. Zbiri, H. Schober, N. Choudhury +5
We report inelastic neutron scattering measurements of the phonon spectra in a pure powder sample of the multiferroic material BiFeO3. A high-temperature range was covered to unrav…
Relationship Between Phonons and Thermal Expansion in Zn(CN)2 and Ni(CN)2 from Inelastic Neutron Scattering and Ab-Initio Calculations
R Mittal, M. Zbiri, H. Schober +4
Zn(CN)2 and Ni(CN)2 are known for exhibiting anomalous thermal expansion over a wide temperature range. The volume thermal expansion coefficient for the cubic, three dimensionally…
