Electromechanical properties of PbTiO3 based piezoelectric ceramics and energy harvesting application of their flexible polymer composites
Ferroelectric and piezoelectric polycrystalline ceramics exhibiting large electromechanical response are sought after in electronic devices such as actuators, transducers in sonar, sensors, accelerators, aerospace, ... -
Macroscopic crowd flow and risk modelling in mass religious gathering
Understanding the principles and applications of crowd dynamics in mass gatherings is very important, specifically with respect to crowd risk analysis and crowd safety. Historical trends from India and other countries ... -
Exploring carrier dynamics in van-der-Waals heterostructures with shot noise spectroscopy, thermoelectricity and opto-electronic study
In the last two decades, there has been tremendous progress in two-dimensional (2D) - material research. It is mainly due to the availability of a large selection of 2D-materials and their van-der-Waals heterostructures. ... -
Allylic Halogenation Route to Latent-Active Trans-Glycosylation of Allyl Glycoside Donors
Allylic halogenation of allyl glycosides as a new route to allyl glycoside donors in glycosylations is investigated in this thesis. Allyl functionality is one of the commonly adopted protecting groups to hydroxyl groups ... -
Aqueous Binary Mixtures: A Study Using NMR Measurements and ab initio Molecular Dynamics Simulations
Binary mixtures having a combination of hydrophobic and hydrophilic groups, such as waterdimethyl sulfoxide (DMSO), water-methanol, water-ethanol, water-tertiary butyl alcohol (TBA), water dioxane, and water-glycerol, ... -
Experimental and Numerical Studies on Chemically Active Flame Inhibitors
Fire hazards pose an increasingly potent threat to modern societies. Early identification and mitigation of fire hazards are crucial to avoid the loss of human lives and property. Recent research suggests that finely-atomized ... -
Tailoring optical and electrical characteristics of layered materials through van der Waals heterojunctions
The feasibility of isolation of layered materials and arbitrary stacking of different materials provide plenty of opportunities to realize van der Waals heterostructures (vdWhs) with desired characteristics. In this thesis, ... -
Design and Development of Fiber Bragg Grating Tactile Sensing Devices for Novel Applications in Engineering and Biomedical Fields
Among the five human basic senses, touch is thought to be the sense that makes the world 'real' to us. Tactile sensors are a category of artificial sensors that acquire information through physical touch. Tactile sensors ... -
Low Power Machine Learning Systems for Energy Efficient Edge Devices
Energy-efficient devices are essential in the world of edge computing and the tiny Machine Learning (tinyML) paradigm. Edge devices are often constrained by the available compu- tational power and hardware resource. To ... -
Development of Graphene Palladium Nanocomposite based Flexible Sensors for Strain and Temperature Measurement
In recent years, device manufacturing technology has been shifted from bulk and thin-film materials to nanomaterials, which are emerged as a unique class of materials. Among all the two-dimensional (2D) nanomaterials, ... -
Large Time Behaviour and Metastability in Mean-Field Interacting Particle Systems
This thesis studies the large time behaviour and metastability in weakly interacting Markov processes with jumps. Our motivation is to quantify the large time behaviour of various networked systems that arise in practice. The ... -
Theoretical Studies on Excited-State Photodynamics: N-H Dissociation in Aniline and Intermolecular H atom Transfer in the 2-Amino Pyridine Dimer
DNA is composed of light-absorbing molecular units like adenine, guanine, thymine, cytosine, etc. It is well-known that DNA as a whole is photostable upon exposure to sunlight. The photostability of biomolecules suggests ... -
A study on Expatriate's adjustment stressors and coping strategies
Adjustment to the cross-cultural environment is inherently taxing for expatriates. Researchers have investigated the implications of cultural stress on occupational stress. However, gaps remain, as follows: (i) There are ... -
PLGA Based Drug Carriers for Treatment of Osteoarthritis
Osteoarthritis (OA) has affected nearly 22-39% of the Indian population and remains one of the most common musculoskeletal disorders that affects articular joints. Post-traumatic osteoarthritis, which develops following ... -
Design and Development of Force Sensor for measurement of Tactile Friction
The sense of touch, along with the other senses, decides the perception of world around us. We touch, grip, and wear various products in our day-to-day life, be it the constant interaction we have with our mobile phones, ... -
Exploration of Ti-based Anodes for Rechargeable Alkali-ion Batteries And Hybrid-ion Capacitors
From 600 B.C. till 1700 A.D., electricity remained the least understood form of energy and was considered "Magical." In the 18th century A.D., the electricity that mysteriously struck Franklin as he arduously flew a kite ... -
Mechanical and curing behavior of tetra-functional epoxy reinforced with nano-fillers
Synopsis Tetra-functional epoxy resins are used as a matrix for aerospace composites owing to their excellent mechanical, adhesive, corrosion resistance and thermal properties. Although epoxy is a high-performance ... -
Analysis of Fracture Processes in Steel Fibre Reinforced Cementitious Composites using Acoustic Emission Testing
Plain concrete has low tensile strength. Steel fibre reinforced concrete (SFRC) is an alternative to plain concrete. One of the major reasons of using the SFRC is due to its high tensile strength. The fracture process ... -
Electronic structure of two-dimensional materials: Effect of point defects and moiré patterns
In the last two decades, research on two-dimensional (2D) materials has gained momentum due to their capability to host a wide range of novel phases of matter. These materials have also found applications in electronic, ... -
Modeling and verification of database-accessing applications
Databases are central to the functioning of most IT-enabled processes and services. In many domains, databases are accessed and updated via applications written in general-purpose lan- guages, as such applications need ...
