Synthesis and liquid crystalline properties of Rufigallol based discotic materials
In 1977 Chandrashekar et al. discovered the discotic liquid crystalline phase. A typical discotic molecule has an aromatic core to which are attached via ester or ether links six to eight alkyl chains, for example benzene ... -
Nucleophilic Boron Chemistry: Catalytic approaches to C-X (X= Br, Cl, O, N) Bond Activation in Metal/Metal-free Conditions
The boron-carbon bond occupies a central position in organic synthesis, functioning as a versatile “universal connector” to a broad range of functional groups. As a result, organoboranes have become indispensable synthetic ... -
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 ... -
The Reactions of Coordinated ligands - A STU D Y O F THE REACTIVITY OF CO O R D IN ATED β-Diketones, β-Ketoimines, and Thio-β-Diketones
Reactions of some Schiff-base complexes of diacetoxy boron with phenylisocyanate and nitrosating reagents have been investigated. Phenylisocyanation produces phenylamido-substituted derivatives by electrophilic attack by ... -
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, ... -
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 structural chemistry - Dipole moments in relation to molecular structure
The dipole moments of p-chlorophenyldichlorophosphine (2.28 D) and p-bromophenyldichlorophosphine (2.04 D) have been determined in benzene at 35 °C. Applying the method of Smith et al., the formal charge distribution in ... -
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 ... -
Potentiometric and spectrometric investigations of cobalt (II) - Ethanolamine (mono, di and tri) complexes
A detailed potentiometric and spectrophotometric investigation of cobalt-ethanolamine (mono-, di- and tri-) complexes has been made. Potentiometric investigations have been carried out at various metal ion concentrations ... -
Oxidation reduction studies in non-aqeous media
This thesis embodies the results of the investigations on the oxidation-reduction behaviour of two typical redox couples in non~aqueous media. The redox systems chosen for the studies are (i) Copper(II) - Copper(l) ... -
Studies in solid state chemistry : Polymorphic transformations 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. ... -
Electrochemical studies of sealed lead-acid battery electrode reactions
Sealed lead-acid battery (SLA), also called valve-regulated lead-acid battery (VRLA), is the subject of considerable research efforts at the present time. There are, however, a few outstanding problems to be solved to ... -
Molecular conformation and electronic structure of compounds related to amides & thioamides - a study by ab initio & semiemperical molecular orbital methods
The molecular conformation of amide derivatives is of paramount importance in understanding the factors which govern the conformations of peptides and proteins. A study of the barriers to internal rotation aids in ... -
Basic studies on electromechanical power sources - Voltage transients, alternating current impedance and steady state discharge characteristics of magnesium-manganese dioxide dry cells and supplementary investigation on titanium-substrate cobalt oxide and magnetite anode development for electrosynthesis
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 ... -
Low-temperature preparatioin and characterization of the perovskite lanthanide chromites and related oxides
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 and ... -
Metal-silicate fractionation in the primitive solar nebula: a computational study of the role of f(O2), P, T and charged 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 ... -
Microscopic modelling of absorption of dipoles in electrical double layer
(i) A three-state model allowing two orientational states for the solvent and one for the organic adsorbate is analysed to obtain the adsorption isotherm. The approximations under which pseudo Frumkin isotherm can arise ... -
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 ... -
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 ...
