Measurement Of Dissociation Constant (Ka) And Partition Coefficient (KP) Of Weak Organic Acids From Their First Hyperpolarizabilities
(2012-05-30)Weak organic acids and their salts are slowly becoming recognized as an important class of materials for second-order nonlinear optics (NLO) due to their high second harmonic generation (SHG). The main advantages in using ... -
Mechanism of electroreduction of nitrobenzene in alkaline media
Nitrobenzene is shown to give a stepwise reduction in certain media. With a view to examine the factors which influence the scheme of reduction, the effect of different solvents and ionic strengths are examined using tast ... -
Mechanistic Insights Into Small Molecule (Amine-Boranes, Hydrogen, Methane, Formic Acid Carbon dioxide) Activation Using Electrophilic Ru(II)-Complexes
(2017-11-09)Current fossil fuels (Coal and Petroleum) based economy is not sustainable in the long run because of its dwindling resources, and increasing concerns of climate change due to excessive carbon dioxide (CO2) emission. To ... -
Mechanistic Investigation and Engineering of a Membrane-Bound Hydrocarbon-Producing Metalloenzyme
The pursuit of sustainable and environmentally friendly fuels, such as biofuels, is gaining attention as an alternative to diminishing fossil fuel resources. Consequently, there is a significant focus on the sustainable ... -
Mechanistic Investigation of Metal Promoted Nucleophilic Additions
(2017-11-30)Nucleophilic additions are an important class of reactions in the preparation of several organic compounds. Metals facilitate nucleophilic additions in many cases. The present work Mechanistic Investigation of Metal Promoted ... -
Mechanistic Studies of Transfer Hydrogenation Catalyzed by Ru(ll)-Half-Sandwich and Group 6 NHC complexes
The thesis explores the mechanistic aspects of transfer hydrogenation of ketones and hydrosilylation of imines; two commonly used organic transformations catalyzed by ruthenium half-sandwich complexes of 2-oxazolidinethiones, ... -
Metal cxhelates in vinyl polymerisation
A general kinetic scheme for the polymerization of vinyl monomers, initiated by dipivaloyl methane chelates of ferric and cupric, was postulated in Chapter III. The results of the spectral investigation complementary to ... -
Metal-silicate fractionation in the primitive solar nebula: a computational study of the role of f(O2), P, T and charged species
This thesis embodies the results of computational studies of the physico-chemical conditions associated with the condensation of high-temperature phases within the primitive solar nebula. The focus of these studies is on ... -
Metallo-β-Lactamase, Phosphotriesterase And Their Functional Mimics
(2011-01-11)Metallohydrolases with dinuclear-zinc active sites perform many important biological hydrolytic reactions on a variety of substrates. In this regard, metallo-β-lactamases (mβ1, class B) represent a unique subset of zine ... -
Methyl Methacrylate Styrene
Polymeric peroxides are mainly a class of 1:1 copolymers of vinyl monomers and oxygen. The study of the formation of these polymers has been instrumental in explaining the inhibitory role of oxygen in vinyl polymerization. ... -
Micro-spectroscopic studies on Mycobacteria & Cancer cells
Evasion of the immune system is a key hallmark of cancer progression. Developing strategies that diagnose early the immune-cancer synapse may lead to long term cures from these aggressive cancers. We aimed to develop optical ... -
Microscopic modelling of absorption of dipoles in electrical double layer
(i) A three-state model allowing two orientational states for the solvent and one for the organic adsorbate is analysed to obtain the adsorption isotherm. The approximations under which pseudo Frumkin isotherm can arise ... -
