Development Of Two Dimensional Correlation And Resolved Methodologies For NMR Spectroscopic Discrimination Of Enantiomers
(2013-01-22)The research work reported in this thesis deals with the development of novel NMR experimental techniques for the spectroscopic discrimination of enantiomers dissolved in a chiral liquid crystalline medium. The information ... -
Developmental Strategies to Address Prosthetic Infection and Magneto-Responsive Biomaterials for Orthopaedic Applications
(2018-05-16)The issue of prosthetic infection leading to implant failure due to the formation of bacterial biofilms on biomaterial surfaces has been widely recognized as a major issue, often leading to revision surgery. The growing ... -
Dharwar stratigraphy and gold mineralisation in Kolar supracrustal belt Karnataka craton India.
The Karnataka Craton is composed of four chief crustal components, viz., the Peninsular Gneiss Complex (PGC), the Sargur Supercrustals, the Dharwar Supercrustals, and the younger granites. The craton is roughly divided ... -

Diffusion In Porous Solids : Void Disorder, Orientation And Rotation, Reaction And Separation, And Levitation Effect
(Indian Institute of Science, 2006-12-12)Diffusion in bulk has been well studied and our understanding may be said to be adequate if not complete. Similarly, surface diffusion has been investigated by a number of workers and a fair understanding of it has emerged. ... -
Diffusion Of Hydrocarbons In Zeolites And Ions In Water
(2013-02-13)Diffusion is a fundamental process which occurs in a wide variety of phases. It plays an important role in chemistry, physics, biology, materials science etc. In recent times, diffusion in confined systems has been widely ... -
Dihydrobenzenes in organicsynthesis
The thesis entitled “Dihydrobenzenes in Organic Synthesis” consists of three chapters. Chapter I Chapter I deals with a brief introduction to the addition of electrons to unsaturated systems, in particular monobenzenoid ... -
Dilute solution on properties of Methyl Methacrylate-Acrylonitrile random Copolymers
The large values of a, the M.H. exponent, suggest that these molecules are highly extended in the solvents studied. Application of S.F. and other existing theories like I.P. to calculate the unperturbed dimensions lead to ... -
Directing cellular differentiation using biophysical cues on multifunctional biomaterial platforms for neural and osteochondral applications
World health organization (WHO) has recognized multiple degenerative diseases as the leading causes of mortality, globally. The drugs-based clinical treatment of chronic degenerative diseases such as multiple sclerosis, ... -
Disorder, Polymorphism And Co-Crystal Formation In Molecular Crystals : An In-Depth Study In Terms Of Weak Intra- And Intermolecular Interactions
(2011-09-21)Three distinct aspects, disorder, polymorphism and co-crystal formation have been addressed in molecular crystals in terms of intra- and intermolecular interactions involving halogens, weak hydrogen bonds and van der Waals ... -
