Nanocrystalline Titania Based Dye Sensitized Solar Cells - Effect Of Electrodes And Electrolyte On The Performance
(2015-07-22)Dye-sensitized solar cells (DSC) have attracted considerable scientific and industrial interest during the past decade as an economically feasible alternative to conventional photovoltaic devices. DSCs have the potential ... -
Nanodevices of Graphene, Carbon Nanotubes and Flow Behaviour of Graphene Oxide Gel
(2018-05-09)In the last three decades carbon nanomaterials such as fullerenes, carbon nanotubes and graphene have attracted significant attention from the scientific community due to their unique electronic, optical, thermal, mechanical ... -
Nanoscale spatial and temporal response of lipid membranes interacting with biomolecules and nanoparticles
The cell membrane is the first point of interaction whenever any external biomolecule or nanoparticle encounters a cell. Thus the nature of interactions between the cell membrane and various proteins, nanoparticles, and ... -
Nature Of Criticality, Structuring, And Phase Behavior Of Complex Fluids
(2009-03-04)This thesis is mainly concerned with some important properties of complex fluids, and how these properties are influenced by structures in the nano/mesoscopic scale. Short-range assembly of the constituent molecules results ... -
Near Optimal Non-malleable Codes and Leakage Resilient Secret Sharing Schemes
A well-studied class of attacks on cryptosystems called "side-channel attacks", stems from the additional access that an adversary can get due to the susceptibility of the hardware on which the cryptosystem (e.g., digital ... -
Neuronal Correlations And Real-Time Implementation Of Spatio-Temporal Patterns Of Cultured Hippocampal Neural Networks in vitro
(2011-01-19)The study of cultured neuronal networks has opened up avenues for understanding the ion channels, receptor molecules, and synaptic plasticity that may form the basis of learning and memory. The hippocampal neurons prepared ... -
A New Method To Determine Optimal Time-Delays Between Switching Of Digital VLSI Circuits To Minimize Power Supply Noise
(2010-06-01)Power supply noise, which is the variation in the supply voltage across the on-die supply terminals of VLSI circuits, is a serious performance degrader in digital circuits and mixed analog-digital circuits. In digital VLSI ... -
New tools to constrain EFTs and CFTs
In this thesis, we develop new methods for the S matrix bootstrap in the context of 2-2 scattering amplitudes and four-point correlators in conformal field theories (CFTs). For 2-2 scattering in quantum field theories, ... -
NMR Investigations Of Oriented Systems : Novel Techniques And Applications
(2011-02-22)This thesis presents results of novel methodologies applied to oriented systems. Both pure liquid crystalline materials as well as molecules oriented in liquid crystalline matrices have been studied. In particular this ... -
NMR Methods For The Study Of Partially Ordered Systems
(2016-11-16)The work presented in this thesis has two parts. The first part deals with methodological developments in the area of solid-state NMR, relevant to the study of partially ordered systems. Liquid crystals are best examples ... -
NMR Relaxation And Charge Transport In Conducting Polymers
(2010-10-14)Conducting and semiconducting polymers, consisting of delocalized π-electrons, have been studied for the past three decades. These materials have shown novel physical properties with interesting applications in batteries, ... -
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 ... -
Non-equilibrium phases, criticality and information scrambling in low-dimensional quantum systems
This thesis contains research works encompassing different areas of quantum condensed matter physics in low dimensions ranging from non-equilibrium phases of matter, quantum criticality in equilibrium systems and quantum ... -
Non-Equilibrium Phenomena in Sheared Soft Matter and Active Granular System
In this thesis, we have studied non-equilibrium phenomena in sheared soft matter systems and in granular active matter. The surfactant systems are driven out of thermal equilibrium by applying external forcing at the ... -
Non-ergodicity in Interacting Quasiperiodic Systems and Disordered Fock Lattice Models
In this thesis, we study different aspects of many body localization in closed quantum systems. Many body localized systems are isolated interacting quantum systems that fail to thermalize on their own (non-ergodic) and ... -
Non-invasive Elastic Property Recovery of Tissue and Tissue-Like Objects from Ultrasound Excited Resonant Modes
This thesis is on non-invasive elastic property measurement of tissue or tissue-mimicking materials through vibro-acoustography and ultrasound assisted diffusing wave spectroscopy (UA-DWS). Towards this, a known force is ... -
Nonequilibrium Fluctuations In Sedimenting And Self-Propelled Systems
(2013-06-10)Equilibrium statistical mechanics has a remarkable property: the steady state probability distribution can be calculated by a procedure independent of the detailed dynamics of the system under consideration. The partition ...
