Development of a Flexible Actuator and Motion Planning for Endoscopic Robots
Endoscopy is a procedure by which a long flexible device called the `endoscope' is inserted into a patient's gastro-intestinal(GI) tract primarily for diagnosis. An endoscope is typically equipped with a camera, ... -
Regulation of auxin response by UBIQUITIN-SPECIFIC PROTEASE14/ TARANI in Arabidopsis thaliana
The genetic pathway regulating auxin response in Arabidopsis is well established and provides us a framework to assess whether TNI belongs to this pathway. The total number of lateral roots is taken as a read-out of auxin ... -
Carbon-Carbon and Carbon Heteroatom Bond Forming Reactions: From Organocatalysts to Quantum Dots
Butenolides containing stereogenic centers on the ring, are commonly encountered structural motifs, found in many natural products. Consequently, there has been considerable interest in efficient and stereoselective ... -
Observational Constraints on Global 21-cm Signal from the Epoch of Reionization
One of the most promising probes of Cosmic Dawn (CD) and Epoch of Reionization (EoR) is the rest-frame global 21-cm signal of neutral hydrogen (HI) produced by the intergalactic medium (IGM) prior to the end of the EoR ... -
Quantum transport in Graphene Moire Superlattice and p-n junction
The discovery of graphene has revolutionized the field of mesoscopic condensed matter physics. It has started a new field of van-der Waals heterostructure in which different two-dimensional materials including graphene can ... -
Influence of Tgf-B on Mechanobiology of Human Breast Cancer Cells
Breast cancers are characterized by extensive modifications to mechanical properties of the tissue via increased ECM production and vascularization. TGF-B is a multi-functional cytokine that is implicated in cancer invasion ... -
Studies on Multilevel Twenty-Four Sided Polygonal Voltage Space Vector Structure Generation With a Single DC Link for Variable Speed Drive Applications
Multilevel voltage source inverters have become a widely accepted and cost-effective power converter technology for applications requiring high-power medium-voltage control. The demand of power level requirement has ... -
Analytical Mellin-Barnes techniques with applications to two-loop SU(3) chiral perturbation theory and QED at higher loops
The present era is one of precision in particle physics. To account for the lacunae in the otherwise successful Standard Model, observables are calculated to high precision in various theoretical models, which are then ... -
Droplet Interface Oscillations using Electrowetting-on-Dielectric (EWOD) for Open-Chip Microfluidic Applications
Droplet manipulation on microfluidic platform has gained significant importance due to its applicability to various healthcare technologies, where larger equipment can be reduced to portable handheld systems based on ... -
Electronic transport in low dimensional LaAlO3/SrTiO3 heterointerface
The large variety of phenomena exhibited by the interface between two band-insulators LaAlO3 and SrTiO3 has attracted intense research activity in recent years.The interplay of different symmetries, viz. point group ... -
Influence of local structure and network connectivity on the electrical switching of some Te-based chalcogenide glasses
Chalcogenide glass (ChG) materials have gained wide attention because of their applications in phase change non-volatile memories (PC-RAM), optical rewritable disks (CD-RW and DVD-RW), infrared detection and thermal imaging. ... -
Understanding the Role of SIRT2 in Cardiac Hypertrophy, Cell Death and Glucose Homeostasis
Over the last century the major causes of human deaths and ailments has shifted from acute infectious diseases to chronic aging related disorders like cancer and type-2 diabetes. The aging process is a universal property ... -
Tuning crystal structures with weak interactions: From solid solutions to stoichiometric cocrystals
This thesis shows that when two organic compounds A and B are cocrystallized and the A∙∙∙B interactions are neither completely isotropic nor anisotropic enough to cause the formation of a stoichiometric cocrystal AxBy, ... -
Self-assembly of Luminescent Metal Nanoclusters, Supramolecular Bile salt based Gels and their Soft Nanocomposites
The thesis is based on the study of the self-assembly of multicolor luminescent nanoclusters, bile salt derived supramolecular gels and soft hybrid gel-nano composites -
Studying bubbles in liquid He4 containing single and many electrons
Helium is an inert element with fully occupied orbitals and is a super fluid at low temperatures. An electron close to the surface of liquid Helium faces a long range attraction due to the finite polarizability of the ... -
Mechanistic Studies of Transfer Hydrogenation Catalyzed by Ru(ll)-Half-Sandwich and Group 6 NHC complexes
The thesis explores the mechanistic aspects of transfer hydrogenation of ketones and hydrosilylation of imines; two commonly used organic transformations catalyzed by ruthenium half-sandwich complexes of 2-oxazolidinethiones, ... -
Dissecting the role of Ataxin 2 Binding Protein 1 in sarcomeric protein stoichiometry and generation of muscle diversity in Drosophila melanogaster
Drosophila muscles are an excellent model to study muscle development, diversity and function. Drosophila muscles consist of two major types –1. Indirect Flight Muscles (IFM), that are fibrillar; as opposed to other tubular ... -
Engineering topological surface states through structural control, electrostatic gating and superconducting proximity effects
Three dimensional topological insulators are materials characterized by a gapped insulating bulk and gapless metallic states on the sample surface. This unique be- havior arises out of the non-trivial topology of the ... -
Structure property correlation studies on Ca-modified Ba(Ti, Zr/Sn)O3 piezoceramics
In this thesis we have investigated the structure, property correlation of the lead-free piezoelectric ceramic of (Ba,Ca) (Ti,Zr/Sn)O3 system. A self-consistent set of experimental techniques such as X-ray powder diffraction, ... -
