Interaction of PbTe with and its alloys at diffusion bonded interfaces: Temperature dependent evolution of phases and microstructure
The past years have seen an increasing interest in high-efficient thermoelectric materials because of their promising application to harvest the widely distributed waste heat. Realizing high-efficient TE materials into ... -
Theoretical investigation of H atom tunneling in Catecholate Monoanion: A combined time-independent and time-dependent quantum mechanical study
This thesis presents a combined time-independent and time-dependent quantum mechanical study of a system, Catecholate Monoanion (CM) for the study of H atom tunneling. It has an intramolecular H bond leading to a symmetric ... -
The dual-targeting of Saccharomyces cerevisiae Pso2 into the nucleus and mitochondria is regulated by post-translational modifications: Implications for organelle-specific DNA repair
The repair of DNA interstrand crosslinks (ICLs) involves the concerted action of multiple DNA repair pathways. In eukaryotes, ICLs are sensed and repaired by replication-coupled or replication-independent mechanisms in ... -
Optimizing the Interval-centric Distributed Computing Model for Temporal Graph Algorithms
Graphs with temporal characteristics are increasingly becoming prominent. Their vertices, edges and attributes are annotated with a lifespan, allowing one to add or remove vertices and edges. Such graphs can grow to millions ... -
Variational Bayes Algorithms for mmWave and Massive MIMO-OFDM Systems with Low Resolution ADCs
In this thesis, we develop novel low-complexity algorithms for massive multiple-input multiple-output (MIMO) systems under practical non-idealities and theoretically analyze their performance. The first problem we consider ... -
Nonlocal continuum models for plasticity and damage
Nonlocal interactions of material points play a vital role in modelling certain important aspects of inelastic phenomena such as plasticity and damage in solids. For plasticity problems, nonlocal interactions allow ... -
Modeling of Permittivity Variations in Stochastic Computational Electromagnetics
With the evolution of 5G systems offering high data rates, major changes are required in the design approach of the components of communication systems. Furthermore, building complex electromagnetic systems at the terahertz ... -
Structural and Biophysical studies to evaluate the influence of oligomerization on biomolecular function
Oligomeric proteins are more common than monomers. This aspect of molecular evolution substantially contributes to functional diversity and the acquisition of features such as cooperativity and regulatory mechanisms. Not ... -
Addressing the Performance and Reliability Bottlenecks in 2D Transition Metal Dichalcogenide (TMD) Based Transistor Technology
In this thesis, we presented different contributions towards the development of 2D material technology. Firstly the realization of desired dimensions over singlecrystal high-quality MoS2 material through dry etching ... -
Inkjet-Printed Ag Nanomaterials based Strain Sensors for Wearable Sensing Applications
Of late, the demand of wearable sensors has exponentially risen. For example, strain sensors that can be worn and are skin mountable play a significant role in the areas of human motion detection, healthcare, soft robotics, ... -
Paper microfluidic tools to improve the sensitivity and dynamic range of point-of-care immunoassays
Over the past decade, developing affordable home-based tests to diagnose infectious diseases has become a pressing need. The lateral flow immunoassay (LFIA) is the most successfully commercialized point-of-care immunoassay. ... -
Reinforcing Visualization Design Using Graphical Primitives of Visual Objects
Data visualization has been established as a powerful tool to help humans understand and communicate information concisely and effectively. It exploits visual perception to extract facts and meanings from data. The ... -
Theoretical Studies of Polymer Dynamics in Confined Spaces
The growing use of micro- and nano-fabricated devices to study complex biological processes has made it increasingly important to understand the effects of confinement on macromolecular behaviour. In this thesis, I will ... -
Investigating Membrane Dynamics And Oligomerization Of Pore-forming Toxins Using Single-molecule Fluorescence Techniques
The biological membrane is a thin fluidic matrix composed of a lipid bilayer that forms the primary cellular barrier against the extracellular environment. The high-density of embedded proteins and glycosylated molecules ... -
Dynamics of river plumes in the Bay of Bengal
The Bay of Bengal (BoB) receives a large amount of freshwater through runoff from sev- eral rivers along its border. This large freshwater gain has severe implications on the dynamics and thermodynamics of the BoB as ... -
Algorithms for Fair Clustering
Many decisions today are taken by various machine learning algorithms, hence it is crucial to accommodate fairness in such algorithms to remove/reduce any kind of bias in the decision. We incorporate fairness in the ... -
Electrical transport study of Graphene/WSe2 Heterostructure
Spintronics has emerged as a novel platform to build information storage and logic devices in the last few decades. Graphene promises a long spin propagation length even at room temperature due to its low spin-orbit ... -
Phenomenological Explorations in Dark Matter
The previous decade has seen an explosive increase in explorations into the nature of dark matter (DM) encompassing astrophysical, particle and cosmological probes. We face today a large body of gravitational evidences ... -
Investigations on Product Purchase Behaviour of Domestic Air Travellers
The Indian civil aviation industry has emerged as one of the fastest-growing industries in the country. Compared to 99 airports in March 2018, nearly 200 operational airports are expected in India by 2040. However, the ... -
Excitons in monolayer transition metal dichalcogenides
Excitons are quasiparticles formed due to electrostatic attraction between the electrons and the holes in a semiconductor. This Coulomb attraction is very strong in the mono- layers of Transition Metal Dichalcogenides ...
