Theory of electrochemical phase formation
In underpotential deposition (UPD), as in other examples of ECPF, many basic questions are yet unresolved. One such question is: Does UPD involve adsorption or phase transition Despite varied experimental observations, ... -
Studies on perovskite type rare earth transition metal oxides as oxidation catalysts
The introductory chapter begins with a classification of the thermal decomposition of solids, followed by a brief account of the decomposition of simple and complex oxalates as well as complex nitrites. The salient features ... -
Reactivity of metastable solids to heat
The thesis embodies investigations on the thermal decomposition of barium azide and the thermal decomposition and sublimation of ammonium perchlorate (AP). A lot of work has been done on the thermal decomposition of these ... -
Studies in phase rule
A brief introduction to the subject of heterogeneous salt systems has been given in Chapter I of the thesis, with particular reference to those involving two salts possessing a common ion, in and without the presence of ... -
Studies in solid state chemistry : Polymorphictransformations of titanium dioxide
The kinetics and energetics of the transformation of pure anatase (tetragonal) to rutile (tetragonal) have been studied. The rate data fit a first-order rate equation, and the activation energy is approximately 90 kcal·mol?¹. ... -
Potentiometric and spectrometric investigations of cobalt (II) - Ethanolamine
Nature of Mononuclear Complexes in Cobalt–Ethanolamine Systems The work presented in this thesis indicates that cobalt forms both pure and mixed hydroxy complexes. The formation constants of complexes such as CoM²?, CoM?²?, ... -
Low-temperature preparatioin and characterization of the perovskite lanthanide chromites and related oxides
Conclusions The thermal decomposition of lanthanum biscitrato chromate(III) dihydrate was investigated in both static air and flowing argon atmospheres. The complex decomposes in four distinct steps, forming oxycarbonate ... -
Basic studies on electromechanical power sources
The extended shelf life of high-energy primary batteries based on lithium, magnesium, and aluminum is primarily attributed to the presence of a protective passive film on the surface of the reactive metal anode. Evaluating ... -
Electrochemical studies of sealed lead-acid battery electrode reactions
From these investigations, it can be concluded that the addition of H?PO? (phosphoric acid) at a concentration of approximately 20 g/L to the H?SO? electrolyte of a sealed lead-acid battery-featuring a low-antimonial lead ... -
Microscopic modelling of absorption of dipoles in electrical double layer
(i) A spin-1 model allowing for induced dipole moment effects is formulated. The analysis, within the mean-field approximation, is deduced and the identity with the earlier approach shown. (ii) A spin-1 model is analysed ... -
Metal-silicate fractionalism in the primitive solar nebula: a computational study of the role of f(O2), P, T and changed species
This thesis embodies the results of computational studies of the physico-chemical conditions associated with the condensation of high-temperature phases within the primitive solar nebula. The focus of these studies is on ... -
Dynamics of bond-formation in some diatomics
An understanding of molecular formation from the separated atoms is one of the important goals in quantum chemistry. Earlier interpretations of the bond formation are based on the spatial characteristics of the charge ... -
Exploring Single-Chain Collapse Transition in Periodically Grafted Amphiphilic Polymers
Synthetic polymers that emulate the complexity and responsiveness of biological macromolecules are at the forefront of modern materials research. One challenge in this field is to design polymer systems that can fold or ... -
Synthesis and Self-Assembly Studies of Carbohydrate-Conjugated Oligo-p-Phenylenes
The structural diversity of carbohydrate derivatives is amplified further by their strong tendency to self-assemble in aq. solutions, provided the molecular constitution and environmental conditions favor. Glycostructures ... -
Studies on the Lewis Acidity of Redox-Active Telluranes and the Catalytic Applications of a Low-Valent Iron Complex
Recent advances in catalysis have expanded the landscape of both main group and transition metal catalysts, moving beyond traditional boron- and aluminum-based main group systems and 2nd -3rd row transition metal systems ... -
Theoretical Investigations of Excited State Proton Transfer in Selected Molecular Systems
Excited state proton transfer (ESPT) plays a key role in various chemical and biological systems, including DNA where it plays a role in the deactivation mechanism. Compared to the ground state, molecules typically have ...
