Aspects of the chemistry of copper(II) complexes having different nuclearity
Synopsis of the thesis entitled “Aspects of the chemistry of copper(II) complexes having different nuclearity” to be submitted by Mrs. K. Geetha under the supervision of Prof. A. R. Chakravarty of the Department of Inorganic ... -
Binding of 9-N-butyladenine with carboxylic acids : Studies on the watson-crick vs. Hoogsteen selectivity
It’s been shown that if the carboxylic group of the acid is in resonance with the adjacent R group, a net preference for the HG site is observed. If the resonance is disrupted in case of aromatic acids by tilting the plane ... -
Dynamical Approach To The Protevin-Le Chatelier Effect
(Indian Institute of Science, 2006-06-07)Materials when subjected to deformation exhibit unstable plastic flow beyond the elastic limit. In certain range of temperature and strain rates many solid state solutions, both interstitial as well as substitutional, ... -
Electronic structure and Photophysical study of semiconducting nanocrystallites
Sizable photocurrent was observed from the CdS-4.5 and CdS-2.2 nanocrystalline films, although the EL efficiency was weak. The I-V characteristic of CdS-4.5 and CdS-2.2 has a typical diode behavior with the onset voltage ... -
In-Situ Synthesis Of A12O3_ZrO2_SiCw Ceramic Matrix Composites By Carbothermal Reduction Of Natural Silicates
(Indian Institute of Science, 2006-06-14)This thesis outlines the work done on in-situ synthesis of Al2O3-ZrO2-SiCw ceramic composites and their property evaluation. The introductory chapter deals with the literature survey on ceramic matrix composites, properties ... -
Semiconductor Photocatalysts For The Detoxification Of Water Pollutants
(Indian Institute of Science, 2006-06-15)Water pollution is a major concern in vast countries such as India and other developing nations. Several methods of water purification have been practiced since many decades, Semiconductor photocatalysis is a promising ... -
Study Of Pulsed Laser Ablated Barium Strontium Titanate Thin Flims For Dynamic Random Access Memory Applications
(Indian Institute of Science, 2006-04-18)The present study describes the growth and characterization of pulsed laser ablated Bao.sSro.sTiOs (BST) thin films. Emphasis has been laid on the study of a plausible correlation between structure and property in order ... -
Supramolecular assemblies of bile acid derivatives
In the early literature, self-associative behaviors of bile acids and bile acid salts were known. Owing to their amphiphilic nature, bile acids can form supramolecular self-assemblies in the form of micelles, helical ... -
Synthesis And Investigation Of Transition Metal Oxides Towards Realization Of Novel Materials Properties
(Indian Institute of Science, 2007-03-23)Transition metal compounds, especially the oxides, containing dn (0 ≤ n ≤ 10) electronic configuration, constitute the backbone of solid state/materials chemistry aimed at realization of novel materials properties of ... -
Synthetic approaches towards 1,24-dihydroxyvitamin D3 and analogues
A formal total synthesis of 1?,24(S)- and 1?,24(R)-dihydroxyvitamin D? (14 and 13) starting from the abundantly available cholic acid (71) is described in this chapter. Cholic acid (71) was first converted into methyl ... -
Thin Films And Sub-Micron Powders Of Complex Metal Oxides Prepared By Nebulized Spray Pyrolysis And Brillouin Scattering Investigations Of Phase Transitions In Solids
(Indian Institute of Science, 2006-06-22)The thesis consists of two parts. Part 1 deals with the preparation of thin films and sub-micron powders of complex metal oxides by nebulized spray pyrolysis (NSP) and Part 2 consists of Brillouin scattering studies of ...
