Brillouin Scattering Investigation of Solvation Dynamics in Succinonitrile-Lithium Salt Plastic Crystalline Electrolytes

Das, Supti; Bhadram, Venkata Srinu; Narayana, Chandrabhas; Bhattacharyya, Aninda J (American Chemical Society, 2011-11-03)

Temperature dependent Brillouin scattering studies have been performed to ascertain the influence of solvent dynamics on ion-transport in succinonitrile-lithium salt plastic crystalline electrolytes. Though very rarely ...
Effect of pressure on octahedral distortions in RCrO3 (R=Lu, Tb, Gd, Eu, Sm): the role of R-ion size and its implications

Bhadram, Venkata Srinu; Swain, Diptikanta; Dhanya, R.; Polentarutti, Maurizio; Sundaresan, A.; Narayana, Chandrabhas (IoP Publishing Ltd, 2014)

The effect of rare-earth ion size on the octahedral distortions in rare-earth chromites (RCrO3, R = Lu, Tb, Gd, Eu, Sm) crystallizing in the orthorhombic structure has been studied using Raman scattering and synchrotron ...
Octahedral distortion induced magnetic anomalies in LaMn0.5Co0.5O3 single crystals

Manna, Kaustuv; Bhadram, Venkata Srinu; Elizabeth, Suja; Narayana, Chandrabhas; Kumar, P. S. Anil (American Institute of Physics, 2014)

Single crystals of LaMn0.5Co0.5O3 belonging to the ferromagnetic-insulator and distorted perovskite class were grown using a four-mirror optical float zone furnace. The as-grown crystal crystallizes into an orthorhombic ...
Spin-Reorientation, Ferroelectricity, and Magnetodielectric Effect in YFe(1-x)Mn(x)O(3)(0.1 <= x <= 0.40)

Mandal, P; Bhadram, Venkata Srinu; Sundarayya, Y; Narayana, Chandrabhas; Sundaresan, A; Rao, C N R (American Physical Society, 2011-09-19)

We report the observation of magnetoelectric and magnetodielectric effects at different temperatures in Mn-substituted yttrium orthoferrite, YFe(1-x)Mn(x)O(3)(0.1 <= x <= 0.40). Substitution of Mn in antiferromagnetic ...
Stress states in individual Si particles of a cast Al-Si alloy: Micro-Raman analysis and microstructure based modeling

Joseph, Sudha; Kumar, S.; Bhadram, Venkata Srinu; Narayana, Chandrabhas (Elsevier Science Sa, 2015)

The stress states in Si particles of cast Al-Si based alloys depend on its morphology and the heat treatment given to the alloy. The Si particles fracture less on modification and fracture more in the heat treated condition. ...
Understanding guest and pressure-induced porosity through structural transition in flexible interpenetrated MOF by Raman spectroscopy

Kumari, Gayatri; Patil, N. R.; Bhadram, Venkata Srinu; Haldar, Ritesh; Bonakala, Satyanarayana; Maji, Tapas Kumar; Narayana, Chandrabhas (Wiley-Blackwell, 2016)

Interpenetrating metal organic frameworks are interesting functional materials exhibiting exceptional framework properties. Uptake or exclusion of guest molecules can induce sliding in the framework making it porous or ...
