Band-matched transport layers and intrinsically stable perovskite solar cells for application to perovskite Si tandem cells
Hybrid perovskite/silicon tandem solar cells offer low-cost alternatives to the commercially established silicon solar cells. In this thesis, we present the material and device optimizations of the subcells that can be ... -
Nodal sets of random functions
This thesis is devoted to the study of nodal sets of random functions. The random functions and the specific aspect of their nodalset that we study fall into two broad categories: nodal component count of Gaussian Laplace ... -
Asymptotic Analysis of Multi-scale, Multi-loop Feynman Diagrams
It is very challenging to solve multi-scale, multi-loop Feynman diagrams analytically. The presence of different kinematic scales makes the computation of Feynman diagrams very difficult, sometimes impossible to get the ... -
Design and Development of Proteasome Activity Modulators: A Novel Strategy for the Treatment of Diabetes Mellitus
Design and Development of Proteasome Activity Modulators: A Novel Strategy for the Treatment of Diabetes Mellitus Abstract The ubiquitin-proteasome system (UPS) is the major pathway for degradation of the intracellular ... -
Role of Lysyl oxidase in TGF-beta-induced Fibroblast Activation and Cancer-Associated Fibroblast-mediated Breast Cancer Progression
Cancer-associated Fibroblasts (CAFs) are a dominant cell type of the breast cancer microenvironment and are proposed to be involved in metastatic progression. TGF-β has been reported to influence fibroblast to myofibroblast ... -
Multiscale Simulation of Nucleic Acid Nanostructures
Nucleic acids, namely DNA and RNA, are arguably the most studied biological molecules. Utilizing the key properties of nucleic acids, such as their persistence lengths and Watson-Crick base-pairing complementarity, ... -
Use of Human Induced Pluripotent Stem Cells as a Model to Study Primary Microcephaly
The aim of this study was to use human induced pluripotent stem cells (hiPSC) to understand key steps of neuronal differentiation and to model the human brain developmental disorder, primary microcephaly (MCPH). MCPH is a ... -
Eutectic microstructures: Role of interfacial energy anisotropy and diffusivities
Eutectic alloys find a wide application in industrial cast alloys, solder alloys, and in the emerging field of functional materials. Apart from technological applications, multiphase eutectic alloys have also received keen ... -
Understanding the regulation of translation and replication of Coxsackievirus B3 RNA by host RNA binding proteins
Coxsackievirus B3 (CVB3) is an enterovirus, with a positive-sense single-stranded RNA genome. The genome contains a single open reading frame (ORF) flanked by untranslated regions (UTR) at the 5’ and 3’ ends. The viral ... -
Versatile sensing platform using silicon photonic microring resonators
Measurement of refractive indices of liquids and thin films can play an important role for chemical analysis in the fields of healthcare and biomedical research. There is a requirement of miniaturized refractive index ... -
Time Domain Spectral Finite Element Simulation of Ultrasonic Wave Propagation in Composite with Defects
Ultrasonic guided wave-based detection of structural defects or damages is one of the promising methods for structural health monitoring (SHM). A significant proportion of structural elements in an aircraft structure and ... -
An Empirical Study of Transformative Learning Resulting Due to Profession Change
A career choice may emerge or be adopted due to personal interest or to balance a range of factors like familial influences, educational qualifications and economic considerations. Once a choice has been made, some follow ... -
Support Recovery from Linear Measurements: Tradeoffs in the Measurement-Constrained Regime
In this thesis, we study problems under the theme of discovering joint sparsity structure in a set of high-dimensional data samples from linear measurements. Our primary focus is on the regime where the number of samples ... -
Estimation of Glacier Mass Balance at Basin Scale in the Himalaya for Recent Decades and Future
The Himalayan glaciers are a major source of perennial river systems which support the livelihood of millions of people in south Asia. Therefore, it is important to understand changes in water resources due to changes in ... -
Fabrication and Characterization of Nanostructured Antibacterial Surfaces
Bacterial antibiotic resistance is becoming wide spread due to the excessive and unregulated use of antibiotics in healthcare and agriculture. At the same time the development of new antibiotics has become slow. Adding ... -
Role of gamma oscillations in processing of natural stimuli
Gamma oscillations (~30-80 Hz) are a prominent signature of electrophysiological signals recorded from the brain with proposed roles in various cognitive functions such as attention and visual perception. Although gamma ... -
Zeolitic Imidazolate Framework (ZIF-8) Supported Nanoparticles: Synthesis and Applications
Nanoparticles have gained great interest in various fundamental and applied areas of science and technology due to their tunable size dependent properties which is not achievable by their bulk counterparts. Nanoparticles ... -
Influence of Surface Topography and Roughness on Lubrication, Friction and Scuffing in High Hardness Steels
In tribology engineering, friction control is a significant challenge. The interacting surfaces of mechanical components are typically designed for best efficiency during tribological operations and are primarily achieved ... -
Understanding the dynamics and evolution of cratons
The earth is the only rocky planet in the solar system that exhibits plate tectonics. One of the basic tenets of plate-tectonics is that it recycles the lithosphere within a few hundred million years. No oceanic lithosphere, ... -
Mechanistic insights into the effects and applications of shockwaves in prokaryotic and eukaryotic organisms
Shock waves are non-linear waves propagating at speeds greater than the speed of sound, with a unique characteristic of instantaneously increasing the pressure, temperature and density of the medium through which they ...
