Sustainable Strategies for E-Waste Management: Bio- Derived Substrates and Heavy metal Remediation Techniques
Monitoring pollution levels and extent is crucial for preserving our environment's sustainability. Advances in the technology sector, facilitated by new materials and methods, have significantly improved. Nonetheless, these ... -
Computational Studies of the Electronic Structures and Ring Contraction Reactions of Pn (n=4-6) Ring in Double and Triple Decker Complexes, and an Orbital Engineering Approach to Stabilise Borozene (B6H6)
The well established chemistry of ferrocene1-3 and different sandwich scaffolds4,5 with organic rings prompted us to explore the electronic structures and reactivity of sandwich complexes involving inorganic rings, i.e., ... -
Aerobreakup of a Polymeric Droplet
Aerobreakup of a liquid droplet refers to the process of breaking the droplet into smaller fragments by subjecting it to a sufficiently high-speed stream of gas (generally air). This process lies at the core of various ... -
Effect of Microstructural Evolution on the Electrochemical Degradation Behaviour of Electrodeposited Tin-Based Coatings
The electrodeposited/electroplated Sn has been used as a protective coating to enhance corrosion resistance, anode material for rechargeable Li-ion battery as an alternative to graphite, decorative finishes, and electronic ... -
ESD Design for Advanced CMOS and Analog nodes
The study of Electrostatic Discharge (ESD) reliability within Integrated Circuits (IC) is crucial due to its direct influence on electronic device performance, longevity, and functionality. As semiconductor technology ... -
Additive Manufacturing of Titanium Alloys for Orthopaedic applications: Processing-Microstructure-Property-Function Relationship
Metallic materials are used for osteosynthesis, and outcomes are expected to be complete healing. The latter part generally becomes unachievable when human subjects need complicated surgery. This situation generally requires ... -
Poleward propagating Tropical Intraseasonal Oscillations over the Indian Ocean
The mechanisms of poleward propagation of tropical intraseasonal oscillations (ISOs) are not well-understood. In this thesis, we investigate this issue for two such tropical ISOs over the Indian Ocean, namely, the Boreal ... -
Role of equatorial convection and moisture in the structure and propagation of Boreal Summer Intraseasonal Oscillations
Boreal Summer Intraseasonal Oscillation (BSISO) is the dominant mode of tropical variability during Boreal summers. BSISO is manifested by northward propagation of the Maximum Cloud Zone (MCZ) from the warm equatorial ... -
Unlocking the Potential of Metal Ions in the Formation of Diverse Self-assembled Structures, Room Temperature Phosphorescence, and Sensing
Metal ions play indispensable roles across diverse processes, both biological and abiological, but their significance in the formation of complex self-assembled structures is only beginning to be understood. Sodium cholate, ... -
A geochemical and Ca-Sr-Nd isotopic study of glacial diamictites, loess and saprolites to understand crustal growth and silicate weathering
Earth is the only rocky planet in the Solar System with a compositionally evolved (felsic) continental crust. This incompatible element enriched layer is dominantly formed by extraction of melt from the upper mantle leading ... -
Symmetric real-closed subsets of affine Kac-Moody Lie Algebras
In this thesis, we study some important classification problems related to affine Kac--Moody Lie algebras. First, we address the combinatorial problem of classifying symmetric real-closed subsets of affine root systems ... -
Simulations and modeling of multiphase gas in the circumgalactic medium
The circumgalactic medium (CGM) plays a critical role in galactic evolution, serving as a complex gaseous environment that hosts most of a galaxy's baryonic matter and mediates intricate gas flows. This thesis presents ... -
Deciphering canonical and non-canonical role of splicing factor Prp16 in pathogenic yeast C. neoformans
RNA splicing is a ubiquitous process during eukaryotic gene expression, where non-coding introns are removed from primary transcripts to form functional mRNA. This vital process is carried out by the spliceosome, a large ... -
Multiscale Modeling of Molecular Sieve Membranes
Gases permeating through nanopores experience selective adsorption with sub-diffusive dynamics. In this work we investigate how the physicochemical properties of nanoporous membranes influence adsorption dynamics of gases, ... -
Effect of Interface Roughness on Mechanical Strength of Adhesively Bonded CFRP Joints- Experimental and Numerical Studies
Composite materials are well known for their superior properties such as specific strength, specific modulus, tailor-ability in different directions, fatigue resistance, durability, low weight, and low thermal expansion. ... -
Delivery Strategies for Dynamic Contents in Edge Caching Systems
In today's digital age, multimedia consumption is pervasive, driven by video-on-demand platforms, online social networks, and sensor networks. Whether it is the latest blockbuster movie on a streaming service or real-time ... -
Examining Climatic Response, Vulnerability and Adaptation in Rural Indian Dwellings to Climate Change: Case studies in three climatic zones
Buildings have evolved traditionally based on local resources and skills. They predominantly relied on passive climate-response mechanisms to provide indoor comfort. However, contemporary buildings, made primarily of bricks, ... -
