Contributions to the understanding of a few concepts in glass science
Lithium Germanophosphate Glasses (xLi O - yGeO - zP O ): Corrected Spelling and Format Lithium germanophosphate glasses (xLi O - yGeO - zP O ) have been synthesised over a wide range of compositions, and their thermal and ... -
Colossal magnetoresistance and related properties of mixed-valent manganites : Studies on polycrystalline solids, thin films and superlattices
A new series La Cd MnO (x = 0.15 and 0.33) has been synthesized by the ceramic method, and their electrical, magnetic, and magnetoresistance properties were studied. Epitaxial thin films of La . Cd . MnO were fabricated ... -
Experimental and modelling studies of glass structure
Elastic properties of alkali phosphomolybdate and phosphotungstate glasses are discussed in terms of their structure. Elastic moduli, Poisson’s ratio and Debye temperature are sensitive to ring structures in the network, ... -
Investigation of AgI-based fastion conductingglasses and composites
In this chapter, the preparation and characterization of a number of AgIbased FICs with the general formula AgI-AgO-MO is presented. Efforts have been made to understand the variation of molar volumes, glasstransition ... -
Polymer dynamics in rate processes
Barrier Crossing and Reaction Dynamics of Polymers: A Kramers Problem Approach Abstract and Synopsis Introduction The Kramers problem for a particle trapped in a metastable well has been studied extensively (P. Hänggi, ... -
synthesis, spectroscopic studies and biological activity of stereochemically constrained enkephalin analogs containing alpha- aminoisbutyric acid
The discovery of endogenous opioids has stimulated considerable interest in the development of structure-activity correlations for enkephalins (Tyr-Gly-Gly-Phe-Met/Leu). However, the flexibility introduced by the Gly-Gly ... -
Investigation of Arsenic Selenium Glasses
This thesis is based on detailed investigations of a variety of physical properties of As-Se glasses. Variation of composition in As-Se glasses results in non-isovalent substitution of the elements. Studies reported in ... -
Microwave synthesis and consolidation of advanced ceramics and ceramic composites
Advanced ceramics constitute an important class of materials. There exists today a wide spectrum of electrical, optical, magnetic and structural applications for advanced ceramics. Structural ceramics are employed in ... -
Isolation and functional charecteristics of xylanases and cellulases of thermoascus aurantiacus
Highly-dispersed platinized-carbon hydrogen anodes are developed for utilization in alkaline and acidic media hydrogen/air fuel cells by tailor-making both their macro and microstructures. The present hydrogen anodes are ... -
Novel electronic structures in transition metal oxides

Metal-insulator transitions in transition metal chalcogenides and oxides investigated by electron spectroscopies
In conclusion, we have investigated the electronic structure of hexagonal and millerite phases of NiS, using various electron spectroscopic techniques to elucidate the underlying electronic structure. Using high-resolution ... -
Investigation of structural phase transitions in inorganic ferroic systems
The thesis entitled "Investigation of Structural Phase Transitions in Inorganic Ferroic Systems" consists of six chapters. Structural changes exhibited by ferroelectric and ferroelastic materials are studied as a function ... -
Investigations On Size Dependence Of Diffusivity In Condensed Media
In summary, the present work reports results for diatomic species AB in zeolite NaY. The results show that when A = B, there is a maximum in the self-diffusivity of the diatomic molecule at large bond lengths c_lab. This ... -
On the role of vibrational-electronic couplings in dictating the ultrafast photophysics of molecular dyads
Ultrafast energy and charge transfer driven by coupled vibrational–electronic (“vibronic”) motions is a central topic in much of photochemistry and photophysics. Accurately describing the quantum dynamics requires an exact ... -
Engineering Photon Emission Statistics of Single Nanocrystals: From Quantum to Classical
The development of stable and bright colloidal nanocrystals has long held promise for quantum photonics, optoelectronics, and bioimaging. Although isolated colloidal nanoparticle can be used for single-photon emission,these ... -
Theoretical studies on collective orientational relaxation, solvation dynamics and electron transfer reactions in dense dipolar liquids
In this thesis, a microscopic study of the collective orientational relaxation and its role in the dynamics of solvation and electron transfer reactions in dense dipolar liquids is presented. The origin of collective ... -
