Carbon aerogel supported first-row transition metal catalysts for methanolyis of ammonia borane
Ni-Ni3B, Co-B, and Co-Ni-B nanocomposites decorated on carbon aerogel were successfully synthesized by adopting the solution impregnation method. The nanocomposites were characterized by powder XRD, transmission electron ... -
Carbon Dots for Next-generation Artificial Lighting Devices
Energy conservation has become a major concern globally in today’s world and artificial lighting (AL) accounts to ~50% of total energy consumption. With increase in population accompanied by modern civilization there is a ... -
Carbon nanomaterials for energy and environmental applications
Environmental pollution and energy storage are two important issues in the modern day society. In this regard, Carbon nanomaterials have attained immense importance, due to their high surface area and electrical conductivity ... -
Carbon Starvation Genes Mediate the Cross-talk Between Metabolism and Pathogenesis of Salmonella Typhimurium
Carbon starvation genes mediate the cross-talk between metabolism and pathogenesis of Salmonella Typhimurium Salmonella enterica serovar Typhimurium (S. Typhimurium) can infect a wide range of host animals to cause diseases ... -
Carbon, oxygen- and nitrogen (six membered ring) annulations
The thesis entitled "Carbon-, Oxygen- and Nitrogen- (Six Membered Ring) Annulations by Vilsmeier Reaction" consists of six chapters. Chapter 1 describes the results of investigations of the Vilsmeier reaction on known ... -
Carbon-Carbon and Carbon Heteroatom Bond Forming Reactions: From Organocatalysts to Quantum Dots
Butenolides containing stereogenic centers on the ring, are commonly encountered structural motifs, found in many natural products. Consequently, there has been considerable interest in efficient and stereoselective ... -
Carrier Mobility And High Field Transport in Modulation Doped p-Type Ge/Si1-xGex And n-Type Si/Si1-xGex Heterostructures
(Indian Institute of Science, 2007-06-26)Modulation doped heterostructures have revolutionized the operation of field effect devices by increasing the speed of operation. One of the factors that affects the speed of operation of these devices is the mobility of ... -
A Case for Protecting Huge Pages from the Kernel
(2018-01-01)Modern architectures support multiple size pages to facilitate applications that use large chunks of contiguous memory either for buffer allocation, application specific memory management, in-memory caching or garbage ... -
Casing boundary layer decelopment in axial impellers with TIP clearence
Casing wall boundary layers are heavily skewed under the action of secondary and tip clearance flows, relative wall motion and the transverse forces associated with the blade rows. The growth of the casing boundary layers ... -
Casing boundary layers in a multistage axial compressor
The casing boundary layers strongly influence the performance of axial?flow compressors. Computational theories exist for calculating casing?wall boundary?layer growth, and although they are relatively successful in helping ... -
Catalysis through molecular association
The thesis entitled "Catalysis through Molecular Association" is divided into four chapters. The objective of the work described here was to develop a new method of ortho-carbonation of phenol in water, at room temperature ... -
Catalytic Asymmetric Direct and Vinylogous Aldol, Michael and Alkylation Reactions
Pyrazoles and pyrazolones are a highly explored and privileged class of aza-heterocycles with a wide range of applications, thereby rendering a recurring interest in their synthesis and functionalization. Majority of the ... -
Catalytic Degradation of Polymers
The effect of various catalysts such as TiO?, cobalt Fischer–Tropsch catalyst, and AlCl? was studied on the thermal degradation of various polymers including poly(vinyl chloride) (PVC), polystyrene, and polybutadiene, both ... -
Catalytic Enantioselective Allylic Alkylative Desymmetrization, Carbon-Carbon and Carbon-Heteroatom Bond Forming Reactions
In summary, we have developed a catalytic enantioselective desymmetrization of prochiral 1,3-dinitropropanes, which proceeds via enantiogroup differentiating allylic alkylation reaction. Functionalized allylic carbonates ... -
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 ... -
Causes and Consequences of Hetrospecific Foraging Associations in Terrestrial Bird Communities
(2018-04-12)The question of group-living in animals has attracted a lot of research attention. Today, we have a nuanced understanding of ultimate explanations and proximate mechanisms for group-living, as well as the genetic basis for ... -
Cavitation and cavitation damage
This thesis deals with the study of certain aspects of cavitation damage. In the first part of the thesis, a critical survey of the existing literature has been made, and various theories of cavitation damage have been ... -
A cavity electromechanical device for superconducting vortex charge sensing
The penetration of magnetic fields in the form of quantized vortices in type-II superconductors is well known. However, it is not well known that such vortices can be electrically charged. The effect is quite subtle and ... -
CcdB : Stability, folding and application to design novel antibacterials
The primary amino acid sequence typically dictates the ultimate conformation of the protein. Mutations in the sequence demonstrate neutral, positive or negative effects on the structure-function relationship of the protein. ...
