Spherical Indentation Response of Bulk and Thin Film Shape Memory Alloys
Shape memory alloys (SMAs) have the ability to recover large strains upon undergoing a thermomechanical cycle. In addition to being used as structural elements, they can be patterned as thin films which can be employed in ... -
Enabling Spectral Diversity in Fiber Laser Systems: Architectures and Applications
Nonlinear effects occur due to the modification of optical properties of a material medium by the presence of high intensity light such as lasers, resulting in the generation of new frequency components. The availability ... -
Biofilm Reactors for Greywater Treatment
Greywater (GW) is the fraction of wastewater discharged in houses that has not been contaminated with faeces. The average volumes of greywater generated in the households of Bengaluru varies between 40-70 litres/cap/day ... -
Surface Adsorption of Dendrimers: Structure, Interactions at Graphene/Water Interface and Applications in Supercapacitors
The study of structure and dynamics of geometrically con ned polymers has been an interesting topic of research. In this thesis we speci cally studied the adsorption behavior of a hyper-branched polymer called poly(amidoamine) ... -
An advection velocity correction scheme for interface tracking using the level-set method
An advection velocity correction (AVC) scheme for interface tracking using the level-set method is presented in this thesis. The key idea is to apply a correction to the interface advection velocity at points adjacent ... -
IO Pattern Aware Methods to Improve the Performance and Lifetime of NAND SSD
Modern SSDs can store multiple bits per transistor which enables it to have higher storage capacities. Low cost per bit of such SSDs has made it a commercial success. As of 2018, cells with an ability to store three bits ... -
Preliminary Investigation into the Cold Plasma Powered Water Gas Shift Reaction – Experiments And Analysis
Water gas shift reaction (CO + H2O ↔ H2 + CO2) is a CO oxidation reaction in the presence of steam resulting in the formation of H2 and CO2. Traditionally, water gas shift (WGS) reaction is achieved using multiple catalytic ... -
Metal Sulphide Based Semiconductors for Solar Photon Energy Harvesting
Sun light is a relatively infinite source of energy available on the earth compared to all other renewable and non-renewable energy sources put together. Harvesting solar photons in an effective and efficient manner can ... -
Multi-faceted modular interactions in proteins
All living systems are composed of plethora of biomolecules. There are various types of biomolecules such as proteins, DNA, RNA, carbohydrates and metabolites. All the reactions in a biological system involve interactions ... -
Functional characterization of Salmonella Typhimurium encoded Cold Shock Protein E during stress responses, biofilm formation and virulence
Overall, this study reports novel functional roles of S. Typhimurium encoded CspE during bile resistance, biofilm formation and in vivo virulence. It also establishes importance of an uncharacterised protein YciF, implicating ... -
Structure-Property Correlation in Binary Immiscible Polymer Blends Compatibilized by Mutually Miscible Homopolymer and Carbonaceous Nanoparticles
The thesis systematically studies the various morphology, mechanical properties, crystallization kinetics and compatibilization effects of homopolymers, carbonaceous nanoparticles such as multiwall carbon nanotubes (MWNTs), ... -
