Crystal Structure Analysis of a (B/a)8-TIM Barrel Enzyme and Its Mutants : Insights into the Role of Interactions Between Termini in Influencing Protein Stability. Experimental and Computational Study of Protein-Surface-Pockets Occluded by Tryptophan Side-Chains
Xylanases (EC 3.2.1.8) are glycosyl hydrolases that catalyze the hydrolysis of internal β-1,4 glycosidic bonds of xylan backbones, and have potential economical and environment friendly applications in the paper pulp, food, ... -
Driven Granular and Soft-matter : Fluctuation Relations, Flocking and Oscillatory Sedimentation
(2018-06-11)Active matter refers to systems driven out of thermal equilibrium by the uptake and dissipation of energy directly at the level of the individual constituents, which then undergo systematic movement in a direction decided ... -
Dynamics of Glass-Forming Liquids and Shear-Induced Grain Growth in Dense Colloidal Suspensions
(2018-06-19)The work presented in this doctoral thesis employs colloidal suspensions to explore key open problems in condensed matter physics. Colloidal suspensions, along with gels, polymers, emulsions and liquid crystals belong to ... -
Electrical Spin Injection and Detection Using Oxide Magnetic Material Fe3O4
Since the proposal of Datta-Das transistor, area of spin injection and detection is in the spotlight for the last decade. Intense research in this field has successfully tackled many issues like conductivity mismatch. Use ... -
Electrical Transport in Si:P and Ge:P δ-doped Systems
(2018-07-30)Doped semiconductor systems have for decades provided an excellent platform to study novel concepts in solid state physics such as quantum hall effect, metal-to-insulator transition (MIT), weak localization and many body ... -
Electron Paramagnetic Resonance and Magnetic Studies of Certain Doped Rare Earth Manganites
Doped rare-earth manganites with the general formula T1xDxMnO3 where `T' is a trivalent rare earth ion, e.g. La3+;Nd3+; Pr3+ etc. and `D' is a divalent alkaline earth ion, e.g Ca2+; Sr2+;Ba2+ etc. display various ... -
Establishing Super- and Sub-Chandrasekar Limiting Mass White Dwarfs to Explain Peculiar Type La Supernovae
(2018-06-23)A white dwarf is most likely the end stage of a low mass star like our Sun, which results when the parent star consumes all the hydrogen in its core, thus bringing fusion to a halt. It is a dense and compact object, where ... -
Flocks, Flow and Fluctuations in Inanimate Matter : Simulations and Theory
In this thesis we study a novel soft-matter system that imitates motility. Our system consists of a few asymmetrically tapered brass rods and aluminium beads which are confined between two vertically shaking plates. The ... -
Growth and Studies of Phase Transitions in Multifunctional Perovskite Materials
(2018-06-11)Crystal growth and characterization of few multifunctional materials with perovskite (ABX3) structure are discussed in this thesis. Efforts were made to modify the magnetic and electric behaviour of these materials by ... -
Planar Hall Effect : Detection of Ultra Low Magnetic Fields and a Study of Stochasticity in Magnetization Reversal
(2018-08-09)In the present thesis, we have explored multiple aspects concerning the stochasticity of magnetic domain wall motion during magnetization reversal, all of which originated from our initial study of magnetic field sensing ... -
Shear Induced Transitions In Mixed Surfactant Systems And Anisotropic Colloids
(2017-06-12)This thesis deals with the non-equilibrium phenomena under shear observed mainly in bilayer forming liquid crystalline phases of mixed surfactant systems, anisotropic colloidal dispersions as well as Langmuir monolayers ... -
Solid State NMR- Development of Methods and Applications to the Study of Materials
In this chapter the application of solid state NMR techniques for the investigation of biodegradable polymers which have wide range of applications in various fields have been presented. Among many polymer systems poly ... -
Study of Evolved Stellar Populations in the Magellanic Clouds
(2018-06-05)The Magellanic Clouds (MCs) consist of a pair of galaxies, the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC), which are located at a distance of 50 kpc and 60 kpc, with stellar masses of 1010 M and 109 ... -
Thermalization and its Relation to Localization, Conservation Laws and Integrability in Quantum Systems
(2018-07-26)In this thesis, we have explored the commonalities and connections between different classes of quantum systems that do not thermalize. Specifically, we have (1) shown that localized systems possess conservation laws like ... -
Thin Film Instabilities Mediated Self-Assembly of Polymer Grafted Nanoparticles
(2018-07-18)After the advent of nanotechnology, self-assembly has become an active area of research, as it being one of the few efficient methods to generate ensembles of nanostructures. In this thesis, we present studies on two ...
