Neutron-Irradiation Induced Magnetization and Persistent Defects at High Temperatures in Graphite
Ranjan Mittal, Mayanak K. Gupta, Sanjay K. Mishra +8
Structural as well as magnetization studies have been carried out on graphite samples irradiated by neutrons over 50 years in the CIRUS research reactor at Trombay. Neutron diffrac…
Defect topology and annihilation by cooperative cascading movement of atoms in highly neutron irradiated graphite
Ranjan Mittal, Mayanak K. Gupta, Sanjay K. Mishra +10
Graphite has been used as neutron moderator or reflector in many nuclear reactors. The irradiation of graphite in a nuclear reactor results in a complex population of defects. Heat…
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…
Phonons and Anomalous Lattice Behaviour in KMnAg3(CN)6 and KNiAu3(CN)6: Inelastic Neutron Scattering and First-Principles Calculations
Baltej Singh, Mayanak K. Gupta, Ranjan Mittal +4
Cyanide based framework compounds are known to show large negative thermal expansion behaviour. Here we report the phonon and anomalous lattice behavior of two metal cyanide framew…
Anomalous Thermal Expansion, Negative Linear Compressibility and High-Pressure Phase Transition in ZnAu2(CN)4: Neutron Inelastic Scattering and Lattice Dynamics Studies
Mayanak K. Gupta, Baltej Singh, Ranjan Mittal +5
We present temperature dependent inelastic neutron scattering measurments, accompanied byab-initio calculations of phonon spectra and elastic properties as a function of pressure t…
