Solid Oxide Based Electrodes for CO2 Reduction
The conversion of CO2 to fuels can be instrumental in reducing future dependence on fossil fuels. High temperature (800oC) electrochemical reduction of CO2 to CO using a solid oxide electrolysis cell (SOEC) provides an ... -
Integrating Computational Tools and Models to Study Positive-sense RNA Virus Lifecycle
Positive-sense single-stranded RNA ((+)RNA) viruses pose significant challenges to public health. Notable families such as Enteroviridae, Flaviviridae, and Coronaviridae have caused epidemics (Dengue, Poliomyelitis, Zika) ... -
Topological Structures and Operators for Bivariate Data Visualization
Understanding complex phenomena in diverse scientific and engineering disciplines often relies on decoding the interplay among real-valued or scalar fields that are measured or computed over a spatial domain. This thesis ... -
Planar tunneling in twisted moire heterostructures
Quantum tunneling is a phenomenon that has excited physicists for many decades. With the ability to exfoliate two-dimensional (2D) materials from the bulk, including graphene, hexagonal boron nitride (hBN), and transition ... -
Single molecule based Super-Resolution Microscopy for disease biology
Advances in single-molecule imaging and super-resolution microscopy have revolutionized the field of cell biology, offering unprecedented insights into complex biological processes at the nanoscale. In this thesis, we ... -
Study of the Effect of Ag-Addition and Double Substitution (Te/Gd and Se) on the Thermoelectric Properties of Cu12Sb4S13 Tetrahedrite
Non-renewable energy sources, such as natural gas, coal, and oil, supply over 80% of the world’s energy demands. The earth’s atmosphere is heavily polluted with CO2 generated from fossil fuels and natural gases, raising ... -
Integrated Photonic Devices in Near-IR to Mid-IR for Agricultural and Environmental Sensing Applications
Near to mid infrared (NIR-MIR) chemical sensing is a remarkably influential analytical technique that capitalizes on the interaction between matter and infrared radiation within a specific wavelength range. Predominantly ... -
Astroglial development as the basis for the effects of early life stress on adult depressive-like behavior
This thesis investigates the enduring effects of early-life stress, specifically maternal separation, on astroglial population and the subsequent behavioral outcomes in adult mice. While the persistent impact of early-life ... -
Morphological Perspectives of Sand Liquefaction and its Mitigation
Liquefaction of soils under seismic conditions has profound implications for infrastructure resilience in earthquake-prone regions. Saturated loose cohesionless granular soils have the tendency to readily lose grain contacts ... -
Single Molecule Based Spatio-temporal Super-resolution Microscopy for Visualizing Single Molecule Dynamics in Cellular System
Over the last decade, single-molecule localization microscopy (SMLM) has developed into a set of powerful techniques that have improved spatial resolution over diffraction-limited microscopy and demonstrated the ability ... -
Reduced Electrolytic Capacitor Based Single-Phase Converters: Topologies, Control, and Stability
Single-phase converters (SPC) find wide applications in different domestic and industrial appliances, ranging from a few hundred Watts to a few Megawatts. Second-harmonic ripple filtering is a critical issue in SPCs, for ... -
Investigating and Modelling the Microscopic Pedestrian Behavioral Dynamics in Mass Religious Gatherings
Pedestrian models that can realistically reproduce observed pedestrian movement dynamics are crucial in facility planning and pre-event planning of crowded situations. Despite the elaborate arrangements, crowd disasters ... -
Insights into Structure-Property Relationships via First Principles and Machine Learning Approaches
The increasing concerns about a sustainable future demand accelerated design and development of new materials with enhanced properties. The process of material development immensely depends on the structure-to-property ... -
Exploration of Design Thinking in School Education
This thesis comprehensively investigates the integration of design thinking into education, focusing on its application in K-12 settings in India. The broad aims of the research work are: 1. To investigate the need to ... -
Geometry of normed linear spaces in light of Birkhoff-James orthogonality
In this thesis, we have tried to understand the geometry of normed spaces in the light of Birkhoff-James orthogonality. Using the first two chapters to give introductory notes and to establish relevant notations and ... -
Micromechanics of Wedge and Cone Indentation of Metallic Specimens with Subsurface Voids
Near-surface voids and pores occur in metal parts manufactured by processes as diverse as casting, powder metallurgy, and additive manufacturing. These pores range in size from a few microns to a few mm, depending on the ... -
Platinum overlayers characterization and fabrication via self-terminating electrodeposition
Hydrogen is considered a promising alternative fuel for the future. However, despite its perception as a “zero-carbon” energy carrier, fossil fuels remain the primary feedstocks for hydrogen production, involving significant ... -
Some investigations into algebraic and geometric properties of Feynman integrals and related topics
We describe our investigations into various formal properties of Feynman integrals and of scattering amplitudes obtained from studying algebraic structures. There are variety of ways to study these properties. Out of which, ... -
The Cahn-Hilliard-Navier-Stokes Framework for Multiphase Fluid Flows: Laminar, Turbulent, and Active
The Cahn-Hilliard-Navier-Stokes (CHNS) framework has found extensive applications, across diverse length and time scales, for multi-phase flows. In this thesis, we demonstrate that this framework offers a robust theoretical ... -
Studies of Pyridoneimine in Site-Selective Functionalization of Carbohydrates and in Multivalent Phenomenon
Carbohydrates are functionally rich biomolecules with multiple hydroxy functionalities. As a result, the most often practiced chemical route is to install protecting groups that permit selective functionalization at the ...
