Studies on the polymerisation of acrylonitrile
The thesis contains the results of the investigations on the kinetics and mechanism of polymerization of acrylonitrile. It is divided into two parts: the first part deals with the initiation of polymerization by ferric ... -
Adsorption of cyclohexanone and its effect on the polarographic reduction of different ions
As a contribution towards the effect of adsorption on electrode kinetics, the adsorption of cyclohexanone and its effect on the polarographic reduction of different ions have been investigated. In Chapter 1 of the thesis, ... -
Theoretical study on intermolecular interactions in the formation of aromatic hydrocarbon dimers
The interaction between two closely lying and parallel aromatic hydrocarbon molecules, one of which is in its singlet excited state and the other in its ground state, leading to the formation of singlet excimers, is now ... -
Asymmetric Catalysis: From Atroposelective Organocatalysis to Iridium-Catalyzed Generation of Central Chirality
Thesis Abstract: This thesis, entitled as “Asymmetric Catalysis: From Atroposelective Organocatalysis to Iridium-Catalyzed Generation of Central Chirality” is divided into three chapters. Chapter 1, highlights the ... -
Exploring the Redox Processes and the Associated Chemical Reactions in Next Generation Rechargeable Li-O2 Batteries
The exceptionally high specific energy of Li-O2 rechargeable batteries makes them promising as a next-generation energy storage technology, beyond the conventional intercalation battery systems such as the lithium-ion ... -
Design Strategies for Janus and Core–Shell Structures and Single- Ion Conducting Membranes Based on Hyperbranched Polymers
Hyperbranched polymers (HBPs) are a class of highly branched macromolecules characterized by their low melt viscosity, high solubility, and numerous terminal functional groups amenable to chemical modification.1 Janus ... -
Molecular design strategy for high EQE and low efficiency roll-off TADF organic light emitting diodes
Purely organic thermally activated delayed fluorescence (TADF) emitters are cost-effective alternatives to the rare-earth-metal-based phosphorescent emitters, offering high exciton utilization for advanced optoelectronic ... -
Mixed Metal Oxide Electrodes for Oxygen Evolution Reaction
This thesis explores transition metal oxide catalysts for the oxygen evolution reaction with a specific focus on cobalt and copper oxides. CoOx is well recognized for it’s OER activity, while CuOx received less attention. ... -
Theoretical and computational studies of solvent and vibrational dynamic effects on electron transfer reactions and overtone vibrational dephasing in liquids
This thesis consists of two parts. In the first part, a detailed theoretical study of the effects of ultrafast polar solvent modes and the intramolecular vibrational modes on electron transfer reaction (E T R ) is ... -
Asymmetric Catalysis, Transition metal catalysis, Allylation, Propargylic alkylation, Cooperative catalysis and nonadjacent stereocenter
Transition metal catalysis has transformed asymmetric synthesis by enabling precise control of stereocenters, essential for bioactive molecules. This thesis outlines a systematic investigation of stereochemical complexity ... -
