Catalytic Organic Transformations with nanostructured metals, alloys and metal Oxides, mesoporous MCM-41 supported metal oxide and Organic-inorganic hybrid materials
Chapter 1 Chapter 1 presents a general introduction to porous materials and, in particular, mesoporous materials. The mechanism of formation of MCM 41 involves supramolecular self assembly of surfactants (e.g., CTAB). ... -
Catalytic Studies with Ru and Ir Half-sandwich Complexes Bearing NHC Ligands
The thesis describes the study of arene-tethered and untethered Ru half-sandwich complexes as catalysts in the addition of hydroelements (E‒H, E = H, B, Si) across unsaturated C-C, C-N and C-O bonds and transfer hydrogenation ... -

Chain dynamics and reactivity studies on polysulfide polymers
Two new classes of polysulfide polymers, viz., PPMEPs and PPEPs, were synthesized and structurally well?characterized using spectroscopic techniques. The presence of unsaturated end groups in PPMEPs was confirmed by NMR, ... -
Charge and Heat Transport in Low-dimensional Quantum Systems
Transport of electrons through low-dimensional quantum conductors like nano-junctions has been actively pursued research area for the last few decades. Experimental studies on nano-junctions are nowadays routinely carried ... -
Charge-Transfer Associated Photoluminescence Of Rare-Earths Doped Oxide Phosphors
(2007-12-29)Luminescent materials can be found in a broad range of everyday applications. While in the seventies and eighties, the field of luminescent materials seemed to be fairly well covered, research in nineties has been revitalized ... -
Chemical Characterisation Of The Surfaces And Interfaces Of Barium Titanate And Related Electronic Ceramics
(2007-10-25)This thesis deals with the investigations on the atomic composition, chemical surface states and microstructural features of barium titanate and other electronic ceramics namely barium polytitantes, calcium manganites and ... -
Chemical investigation of vegetable oils
In this thesis are presented the author’s contributions towards the systematic analysis of some Indian vegetable oils and also the medicinal applications of some of them. These have been separated by combined fractionation ... -
Chemical models for penicillin allergenesis
The thesis entitled “Chemical Models in Penicillin Allergenesis” is divided into three chapters. Chapter I – Introduction and Background The first chapter deals with a résumé of the problem and enumerates the present status ... -
Chemical Modulation of Ferroptosis in Mammalian Cells by Synthetic Organoselenium and Gold-based Small Molecules
Oxidative stress induced by reactive oxygen species (ROS) plays a crucial role in triggering various forms of cell death, including apoptosis, autophagy, and necrosis. In recent years, a distinct and regulated form of cell ... -
Chemical petrology of ultramafites and the origin of magnesite deposites of Musorre District, Karnataka
Any attempt to classify the ultramafites of the Sindhuvalli–Talur area should take into consideration the field features, petrography, and the chemistry of the whole rock as well as the individual mineral phases. Field ... -
Chemistry of bimetallic, chalcogenide and highly reactive metal nanoparticles
The remarkable modifications in the characteristics of materials on a nanoscale, caused by surface effects, quantum confinement, and dependence on shape, leads to diverse applications of nanomaterials, such as in catalysis, ... -
Chemistry of carbonized metallic nanomaterials
Magnetic nanomaterials have received significant attention because of their remarkable properties enabling applications in various fields such as catalysis, as contrast agents for magnetic resonance imaging, in sensing ... -
Chemistry of dihydrogen complexes of ruthenium bearing only phosphorus ligands
Combustion of solid composite propellant is characterised by its rapidity and the highly complex nature of the various physico chemical phenomena taking place both in the flame zone and in the solid phase of the combustion ...
