Thermalization and its Relation to Localization, Conservation Laws and Integrability in Quantum Systems
(2018-07-26)
In this thesis, we have explored the commonalities and connections between different classes of quantum systems that do not thermalize. Specifically, we have (1) shown that localized systems possess conservation laws like ...
Raman Spectroscopy Of Graphene And Graphene Analogue MoS2 Transistors
(2016-06-18)
The thesis presents experimental studies of device characteristics and vibrational properties of atomic layer thin graphene and molybdenum disulphide (MoS2). We carried out Raman spectroscopic studies on field effect ...
On the Nature Of Propagating MHD Waves In The Solar Atmosphere
(2014-10-15)
One of the most persistent problem in solar physics is the identification of the mechanism that heats the solar corona and accelerates the fast solar wind. Magneto-hydrodynamic (MHD)waves play a crucial role in heating of ...
Observational Aspects Of Core Collapse Supernovae
(2013-10-17)
The discovery of several bright supernovae (SNe) in recent years has evoked a great deal of interest in these objects. The study of these objects are of importance not only as probes to the end stages of stellar evolution, ...
Physics Of Conductivity Noise In Graphene
(2014-05-27)
This thesis describes the conductivity fluctuations or noise measurements in graphenebased field effect transistors. The main motivation was to study the effect of disorder on the electronic transport in graphene.
In ...
Experimental And Theoretical Studies Towards The Development Of A Direct 3-D Diffuse Optical Tomographic Imaging System
(2014-06-02)
Diffuse Optical Tomography is a diagnostic imaging modality where optical parameters such as absorption coefficient, scattering coefficient and refractive index distributions are recovered to form the internal tissue ...
Charge Transport In Conducting Polymers, Polymer-Carbon Nanotube Composites And Devices
(2014-02-26)
The Thesis reports charge transport studies on conducting polymers, polymer carbon nanotube composites and organic semiconductor devices. Conducting and semiconducting polymers consisting of π-conjugated chains have ...
Charge Transport And Magnetic Properties Of Iron-embedded Multiwall Carbon Nanotubes
(2014-06-12)
Studies on charge transport properties in carbon nanotubes (CNTs) have been a subject of great interest for a long time not only as an important topic in fundamental science, but also as a basic requirement for the application ...
Crystal Structures of Sortase A from Streptococcus Penumoniae : Insights into Domain-Swapped Dimerization. Crystal Structures of Designed Peptides : Inhibitors of Human Islet Amyloid Polypeptide (hIAPP) Fibrillization Implicated in Type 2 Diabetes And Those Forming Self-Assembled Nanotubes
(2017-09-27)
Sortases are cell-membrane associated cysteine transpeptidases that are essential for the assembly and covalent anchoring of certain surface proteins to the cell wall in Gram-positive bacteria. Thus, they play critical ...
