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 ... -
Dissimilar Hetero-Interfaces with Group III-A Nitrides : Material And Device Perspectives
(2017-10-31)Group III-A nitrides (GaN, AlN, InN and alloys) are materials of considerable contemporary interest and currently enable a wide variety of optoelectronic and high-power, high-frequency electronic applications. All of these ... -
Dissipative Mechanisms in Organic Light-emitting Diodes: Role of Intramolecular Charge Transfer and Delayed Fluorescence
Organic light-emitting diodes (OLEDs) are emerging to replace conventional lighting technology due to their flexible device structures, multicolour emission, and ease of fabrication. However, one of the key challenges in ... -

The present thesis consists of four parts. They deal with the synthesis of the disulphonamides of diphenylamine, phenylbenzylamine, dibenzylamine, diphenylhydrazine and dibenzylhydrazine and their starting materials. Part ... -
Diverse Applications of Luminescent Metallocholate Hydrogels
Supramolecular gels are soft materials consisting of a solid three-dimensional network with noncovalent interactions such as hydrophobic interactions, hydrogen bonding, cation-п, and п- п interactions. Due to their soft, ... -
Diversity and Structure-Property Correlation in Disordered Multicomponent Organic Crystal Forms
The search for new multifunctional materials continues unabated, and with the realization that in solids, the material property can be tailored using the variability provided by molecular and submolecular forces. Harnessing ... -
Doping And photophysical Properties Of II-VI Semiconductor Nanocrystals
(2010-06-03)Semiconductor nanocrystals with sizes comparable to the corresponding bulk excitonic diameter exhibit unique size-dependent electronic and optical properties resulting from quantum confinement effect. Such nanocrystals not ... -
A Dynamical Approach to Plastic Deformation of Nano-Scale Materials : Nano and Micro-Indentation
(2017-11-22)Recent studies demonstrate that mechanical deformation of small volume systems can be significantly different from those of the bulk. One such interesting length scale dependent property is the increase in the yield stress ... -
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, ...
