Spectrally selective tandem absorbers for photothermal conversion in high temperature solar thermal systems
Solar energy is the inexhaustible and abundant energy resources on the earth which can be a best substitute for the fossil fuels. Over the past couple of decades, all the solar technologies are rising very steadily in two ... -
Synthesis and development of multifunctional carbonaceous nanostructures for magnetic, optical and catalytic applications
Owing to the ease of functionalization, low synthesis-cost and polymorphism, carbonaceous nanostructures such as carbon globules, nanotubes (CNTs) and graphene sheets emerged technologically as one of the most important ... -
Blast Mitigation Strategies for Marine Sandwich Structures
Blast mitigation is being researched from the time of world war II. There were full field blast tests and analytical studies on the performance of monolithic structures to mitigate blast load. Sandwich structures were also ... -
Bubble and conical forms of vortex breakdown in swirling jets
The present study focusses on vortex breakdown (VB), which occurs in axially convected swirling flows and is characterized by the development of an internal stagnation point and regions of reverse flow. VB has been ... -
Mass Transport in Cu-Interlayer-Si Systems under Various Thermo-Electro-Mechanical Excursions
This work falls in general area of the electro-thermo-mechanical driven mass transport in Cu-Si systems, which often finds relevance while accessing reliability issues pertaining to thin film interconnects in microelectronic ... -
An Exploratory Study on Financial Resources, Scaling, and Performance of Social Enterprises in India
The limitations of the government and current economic system deprived socio-economic opportunities to certain sections of the communities. The non-profit sector, expected to fill this gap, has been afflicted with fiscal ... -
Dispersal Patterns and Processes in Littorinid Snails along the Indian Coastline
Dispersal has important ecological and evolutionary consequences for a species. Marine dispersal is unique because of facilitation by ocean currents, where oceanography interacts with species traits and environmental ... -
An Approach Towards Inactivation of Susceptible and Antibiotic Resistant Bacterial Contamination using Novel Photo–(electro)-catalysts
Water in most rivers in India does not meet the standards for drinking and even for bathing purposes due to the high concentration of coliforms, organic and inorganic contaminants. Overuse, uncontrolled release and careless ... -
Study of Phase Equilibria and Interfacial Properties of Systems Containing Clathrate Hydrates Using Molecular Simulations
Gas hydrates, also known as clathrate hydrates are nonstoichiometric and crystalline solids composed of water and gas molecules. If the gas molecules are natural gas components, such as methane, ethane, propane, etc., ... -
Methodologies for Risk Assessment of Landslides Induced by Rainfall and Earthquake
Landslide is one of the greatest natural catastrophes and poses a major threat to lives and property worldwide. As development expands into unstable hill areas under the pressure of increasing population and urbanisation, ... -
Spatio-temporal Memories: Theory and Algorithms
This thesis is primarily focused on building a systematic theory for spatio-temporal memories based on unsupervised learning and exploring its applications. Also, contributions are made in the area of supervised learning ... -
The Crystal Form Diversity From Cocrystals To Eutectics: Design, Synthesis, Production And Property Evaluation
This thesis aims to design and synthesize organic molecules to generate properties like SHG, ferroelectric and dielectric. In continuation, we have done cocrystallization studies to study the trend in between the two ... -
Novel Therapeutic Targets for Alzheimer’s Disease
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by impaired memory and other cognitive deficits. Even though the genes associated with familial AD were discovered more than three decades ... -
Analysis of Printed Periodic Structures and Their Applications in Antennas and Absorbers
To meet the demand of continuously growing RF and microwave technologies, scientists and engineers have developed innovative materials consisting of conducting and dielectric materials that overcome limitations in the ... -
Studies on Flow Dynamics and Spray Swirl Interactions in Gas Turbine Combustor
Coupling of spray with the coherent structures of a highly turbulent flow has been a long-standing problem especially in the context of liquid fuel delivery systems in gas turbine combustors. The atomizer in a gas turbine ... -
Atom-to-circuit Modeling Strategy for 2d Transistors
Two-dimensional materials are now being considered as viable options for CMOS (complementary metal-oxide-semiconductor) technology extension due to their diverse electronic and opto-electronic properties. However, introduction ... -
Development of the Combined Methodology to Understand Designers’ Experimentation and GO-NO-GO Decision-Making during New Product Design and Development
New Product Development (NPD) is the most important activity, which is recognized as the growth engine for product centric organizations to sustain, prosper, and accumulate stakes in the market. Development of new products ... -
Photo-responsive Self-assembled Coordination Architectures and Their Applications
Development of nanomaterials that mimic enzyme-like catalytic activities (nanozymes) has drawn special attention in recent time. Nanozymes possess exclusive advantages over natural enzymes like high stability, large-scale ... -
Light and magnetic field induced coherence effects in atoms
In this thesis, we have studied the coherence effects in atoms induced by light and a magnetic field. After giving an introduction to the contents of the thesis, details about the theory and the experimental setup used are ... -
Studies on Layered Ternary Metal Chalcogenides: Electronic devices, Sensors and Electrocatalysis
