Tuning Electrical and Thermoelectric Properties of Molecular Junctions by External Stimuli: From Monolayers of Molecules to Amorphous Polymer Thin Films
Molecular electronics explores electronic functionality at the sub-nanometer scale by utilizing individual molecules as active components. The molecules provide unique advantages such as extreme miniaturization, chemical ... -
Transition in flexible tubes and channels
A combination of experiments, flow simulations and linear stability analysis is used to develop a fundamental understanding of the instability and transition in flows through flexible tubes and channels. The present study ... -
Dehydration of alcohols
Catalytic vapor phase dehydration of i-propanol, n-butanol, i-butanol, s-butanol and t-butanol is studied in a fixed bed flow reactor under isothermal conditions over various catalysts to understand the influence of catalyst ... -
Estimation of thermophysical properties of organic liquids: diffusion coefficients and excess volumes.
The objective of this work is to experimentally determine the thermophysical properties such as diffusion coefficients and excess volumes of mixing of some organic liquids, specifically of binary systems involving the ... -
Oxidation of Alcohols
Oxidation of ethanol and methanol are known to be feasible reactions. Equilibrium constants calculated show that these reactions are highly irreversible. Theoretically ethanol and methanol oxidations to their respective ... -
Modeling of Coalescence Cascades in Liquid-Liquid dispersions
Agitated dispersions of one liquid in another immiscible liquid invert at a critical value of dispersed phase fraction, nearly catastrophically. The dispersed phase becomes continuous and vice versa. This phenomenon has ... -
Studies in gas-solid reactions
Non-catalytic gas-solid reactions are of great industrial importance and have therefore attracted considerable research effort. As a result, a number of models have been proposed in literature. Among the early models, the ... -
Polysterene-based compatibilizers for polymer blending : main chain epoxidation of high molecular weight polystyrene
Polystyrene has often been functionalized for its use in various commercial applications, but most often the reactive functional groups have been substituted on its benzene ring. In the present work, epoxy functional groups ... -
Bay of Bengal freshwater in the tropical Indian Ocean
The annual total continental runoff into the Bay of Bengal (BoB) is more than half the runoff into the entire tropical Indian Ocean. The net freshwater (FW) content in the Bay of Bengal mixed layer increases from a minimum ... -
Predictability of tropical coupled ocean-atmosphere model and its dependence on initial conditions
El Niño and Southern Oscillation (ENSO) is the dominant interannual signal in the tropics. This aperiodic phenomenon arises out of strong interactions between the tropical ocean and the atmosphere. Investigations with ... -
Andaman sea circulation in a high-resolution OGCM
The objective of this study is to understand the circulation of the Andaman Sea, which is unique by geography and oceanography, using a high-resolution Ocean General Circulation Model (ROMS) in tandem with altimeter and ... -
Investigation on the linkage between mystery of excess atmospheric absorption and state of mixing of aerosols
In order to understand the response of the Earth–atmosphere system to anthropogenic aerosol forcing, it’s essential to know the relative impact of the various aerosol species on the radiation budget. Most of the models ... -
Physico-chemical studies on hen's egg yolk lipovitellins and very low density lipoprotiens
The work described in this thesis can be broadly classified into two major sections namely, (1) Chemical studies, which describes the preparation of lipovitellins, fractionation of their protein components and comparison ... -
Studies on chemical modifications of enzymes with O-Benzoquinone. A new reaction of the Quinone with Methionine
The thesis deals mainly with studies on a new reaction of o-benzoquinone with methionine. o-Benzoquinone is a highly reactive compound which takes part in many complex reactions with proteins. Some of the functional groups ... -
Studies on the metabolism of riboflavin nucleotide coenzymes in plants
A survey of literature indicates that although the occurrence of B-vitamins in higher plants is well known and also that several plant enzymes require the presence of these for their action, very little work has been carried ... -
Studies on vitamin carrier proteins: physicochemical and functional aspects
STUDIES ON VITAMIN CARRIER PROTEINS: PHYSICOCHEMICAL AND FUNCTIONAL ASPECTS submitted by P.B. SESHAGIRI for the award of Ph.D. degree of the Indian Institute of Science, Bangalore, India. Investigations detailed in this ... -
Studies on vitamin carrier protiens hormonal induction and modulation of ribflavin carrier protien and retinol
STUDIES ON VITAMIN CARRIER PROTEINS: HORMONAL INDUCTION AND MODULATION OF RIBOFLAVIN CARRIER PROTEIN AND RETINOL BINDING PROTEIN IN IMMATURE CHICKS submitted by B. Durga Kumari for the award of the degree of Doctor of ... -
Bacterial transformation of nitroaromatic compounds and its implicatins in detoxification
Nitroaromatic compounds form a major group of environmental pollutants because of their high toxicity, widespread use, and recalcitrance to microbial degradation. The studies incorporated in this thesis aimed at understanding ...
