Reductive And Metathetic Coupling Reactions Mediated By Group (IV) Metal Alkoxides
(2010-10-19)Several organic transformations are mediated by group(IV) metal alkoxides. The reactivity is based on the basic nature of alkoxide group, Lewis acidic nature of the group(IV) metals, insertion of unsaturated molecules into ... -
Antioxidant Activity Of The Anti-Inflammatory Compound Ebselen And Its Analogues : Role Of Nonbonded Interactions
(2010-10-05)Although considered as a poison for long time, the importance of selenium as an essential trace element is now well recognized. In proteins, the redox active selenium moiety is incorportated as selenocysteine (Sec), the ... -
Statistical Mechanical Models Of Some Condensed Phase Rate Processes
(2010-09-13)In the thesis work we investigate four problems connected with dynamical processes in condensed medium, using different techniques of equilibrium and non-equilibrium statistical mechanics. Biology is rich in dynamical ... -
Theoretical And Spectroscopic Studies On Weakly Bound Complexes And Acetylene
(2010-09-03)Atoms construct the molecules and molecules construct the material substances (with the exceptions as well, e.g.., metals, where atoms directly construct the material substances). Intermolecular interactions play an important ... -
Modelling Stochasticity In Selected Biological Processes
(2010-08-16)Biological processes at the cellular level take place in heterogeneous environments, and usually involve only a small number of molecules. They tend to exhibit strong time dependent fluctuations, as a result, and are, ... -
Theoretical Investigations Of Structure, Energy And Properties Of A Few Inorganic Compounds
(2010-08-11)This thesis reports the theoretical investigations aimed at understanding the structure, stability and properties of a few inorganic compounds. The first chapter presents an introductory overview of the theories used to ... -
Probing The Origin Of Second Harmonic Generation From Copper Nanoparticles In Solution By Hyper-Rayleigh Scattering
(2010-08-09)In recent years, coinage metal nanoparticles have emerged as materials with largest quadratic optical nonlinearity. Their first hyperpolarizabilities (β) are very high (105-106 x 10-30 esu) but such large values were quite ... -
Chiral Bisphosphinites For Asymmetric Catalysis
(2010-07-21)Chiral bisphosphinites are well-documented alternatives for chiral bisphosphines as ligands that can be exploited in various asymmpetric syntheses. Particularly, vicinal biarylphophinite ligands give a seven membered chelate ... -
Mapping The Reaction Coordinate For The Oxidative Addition Of Molecular Hydrogen To A Metal Center
(2010-07-15)The binding of molecular hydrogen to a metal center leads to the elongation of the H−H bond and subsequently to its cleavage along the reaction coordinate for the oxidative addition of H2. There has been considerable ... -
Quadratic Optical Nonlinearity And Geometry Of 1:1 Electron Donor Acceptor Complexes In Solution
(2010-06-04)The knowledge of geometry of molecular complexes formed via molecular association in solution through weak interactions is always important to understand the origin of stability and function of an array of molecules, ... -
Functional Hyperbranched Polyethers Via Melt-Transetherification Polymerization
(2010-04-12)Dendrimers are highly branched macromolecules which are prepared by a stepwise procedure. The presence of a well-defined core, discrete generations and a large number of terminal groups in dendrimers make them structurally ... -
Electrochemical Studies Of Polyaniline And Some Of Its Applications
(2010-03-03)The studies reported in the thesis deal with surface modification of non-platinum metals by coating with electronically conducting polymers, namely, polyanilne (PANI) and polypyrrole (PPY). The oxidation of Г/I2, ... -
