Studies on pressed and roll-compacted alkaline iron-electrodes for nickel-iron secondary cells
It is concluded that various sulfide additives employed in this study retard passivation of the iron electrode during discharge and suppress the rate of the HER during charging. The electrodes doped with Bi?S? show minimum ... -
Synthesis, structure and properties of inorganic-organic hybrid compounds
Synthesis, structure, photodimerization, structural transformation and photocatalytic studies have been carried out on a family of cadmium thiosulfate compounds with varying dimensionalities. The observation of unique Cd?S? ... -
Electron spectroscopic investigations of nitrogen adsorbed on transition metal surfaces and of oxide superconductors.
1.4 Conclusions The core and valence level binding energies and vibrational stretching frequencies of nitrogen adsorbed on clean as well as modified transition?metal surfaces are summarized in Tables I.1–I.3. From Table ... -
Nanocrystals and nanocrystalline films of metal oxides and related materials
Certain observations and conclusions regarding the investigations presented in Chapters 5 to 9 are described here. The analysis is in relation to the ‘SCOPE OF THE WORK’ indicated in Chapter 1. The present work is mainly ... -
X-ray spectroscopic and magnetic....systems
The thesis is primarily based on detailed studies of transition metal oxide systems employing X?ray absorption spectroscopy, X?ray photoelectron spectroscopy and magnetic susceptibility measurements. Chapter I deals with ... -
The fate of phase transitions in VO2 on doping
Ever since its discovery more than six decades ago, thermally-induced insulator-metal transition (IMT) in vanadium dioxide (VO2) has attracted much attention, not only because of its near-room temperature IMT at ~340 K, ... -
Understanding RNA-Metal Ion Interactions: RNA Folding Pathways and Ion Selectivity
Ribonucleic acid (RNA) plays diverse and critical roles in cellular function. For most biological functions, RNA must fold into specific three-dimensional structures, and physiologically abundant monovalent (Na+ and K+) ... -
Computational studies of the effect of confinement in Zeolitic cavities on the diffusion of monatomic Sorbates and the melting characteristics of Argon Clusters
The present chapter has attempted to study the temperature dependence of the levitation effect. It has been shown that this effect is most pronounced at lower temperatures and decreases in intensity at higher temperatures. ... -
Theortical studies of polar solvation dynamics, ionic mobility, solute diffusion and activated barrier crossing dynamicsin dense liquids
There are several features of this chapter that are new. The self-motion of the probe solute has been incorporated here for the first time and studied systematically. The theoretical approach captures quite successfully ... -
Computer simulation studies of orientational relaxation in strongly correlated dipolar systems
In the preceding three chapters of this thesis, computer simulation and theoretical studies of orientational relaxation in dipolar liquids and solids have been presented. The primary objective has been to understand the ... -

Theoretical studies of barrierless and very low barrier chemical reactions in solution
The above review of experimental investigations on the photophysics of stilbene and related compounds and the torsional dynamics of TPM in dyes in condensed phase clearly indicate a strong influence of viscosity and polarity ... -
Novel layered & three-dimensional oxides of perovskite & related structures: synthesis & investigation of ion-exchange & intercalation
In this chapter, we have described the synthesis of a new series of protonated layered perovskites of the formula, HCa???La?Nb???Ti?O??, from the corresponding potassium compounds by ion-exchange. The protonated compounds ...
