Protein Folding, Function and Aggregation Role of Co-solvents and Topological Frustration
Proteins are biological macromolecules formed by sequentially joining natural amino acids through peptide bonds. The sequence of amino acids in a protein chain determines its three dimensional structure under physiological ... -
Disruptive Approaches to Address Performance & Reliability Challenges in 2-Dimentional (2D) Material Based Transistors & Memories
In 2020, Apple introduced its most advanced laptop that has the A14 Bionic processor. The very first processor, Intel’s 4004, was launched in 1971 and had a transistor (the basic building block of a processor) density of ... -
The Effect of Gamma Radiation on Protein Structure and Dynamics
Gamma radiation being the most energetic form of electromagnetic radiation has applications in number of different fields such as in medicine for treating cancer, food sterilization and in astronomy for studying phenomenon ... -
Effects of Steroid Hormones on Insulin Sensitivity and Lipogenesis: An Insight into the Involvement of the Wnt Signaling Pathway
The shift in maternal energy metabolism characteristic of pregnancy is thought to be driven by various hormonal changes, especially of ovarian and placental steroids. In this context, the effect of estradiol (E2), progesterone ... -
Interpretation of 2-Dimensional NMR spectra of small molecules
Nuclear Magnetic Resonance (NMR) spectroscopy has had an enormous effect in numerous areas of chemistry, biology, and medicine. Nuclear Magnetic Resonance (NMR) Spectroscopy is a unique analytical technique that permits ... -
Resistive Switching and Electron Transport In Perovskite Oxide Thin Films
This work deals with the Resistive Switching (RS) properties of various perovskite oxides probed in a simple Metal - Insulator - Metal (M-I-M) configuration. The metals comprise of platinum which served as the bottom ... -
Graphene and Graphyne based three dimensional porous architectures
The main objective of the thesis is to introduce porous structure into graphene/graphene oxide materials and study their effects on various physics/chemistry related applications. Introduction of porosity may be achieved ... -
Advanced Instrumentation for Detection of Defects and Diseases in Sericulture
Sericulture is the art of rearing silkworms for silk production. The matured silkworms will be spinning cocoons as a protective shield before they undergo metamorphosis. These cocoons are immersed in boiling water to soften, ... -
Towards Logic Circuit Applications Using Solution Processed CNTs
With Silicon transistor technology reaching its practical limits, e orts to replace Si with new materials with better electronic transport properties have gained considerable at- tention. Single-walled carbon nanotubes ... -
Oxidation of CO Catalysed by Nanometric Mono and Bi-Noble Metals on Various Oxide Supports
Air pollution results mainly from the injurious smoke emitted by cars, buses, trucks, factories etc. This smoke contains carbon monoxide, unburned hydrocarbons and oxides of nitrogen and sulphur. In case of cars, catalytic ... -
Mechanistic insights into the replication of Sesbania mosaic virus
The present thesis deals with the mechanism of replication of Sesbania mosaic virus (SeMV), which belongs to the genus sobemoviruses. Sobemoviruses are single stranded positive sense RNA viruses which infect both mono and ... -
Optimisation of Coating Protocols for Etched Fibre Bragg Grating Sensors and Applications in Sensing
Fibre Bragg grating sensors, characterised by high sensitivity, flexibility, and immunity to electromagnetic interference, have found applications in commercial-grade temperature and strain sensors. Removing the clad, ... -
