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 ...
Spiral-Wave Dynamics in Ionically Realistic Mathematical Models for Human Ventricular Tissue
(2018-04-18)
There is a growing consensus that life-threatening cardiac arrhythmias like ven- tricular tachycardia (VT) or ventricular fibrillation (VF) arise because of the formation of spiral waves of electrical activation in cardiac ...
Tomographic Studies of Pulsar Radio Emission Cones and Searches for Radio Counterparts of Gamma-Ray Pulsars
(2018-04-18)
Radio emission from pulsars is believed to originate from charged particles streaming along the open magnetic field lines, radiating within a narrow cone at each of the two magnetic poles. In each rotation of the star, the ...
High Magnetic Field Neutron Stars : Cyclotron Lines and Polarization
(2018-04-16)
This thesis concerns with the study of X-ray binaries which are gravitationally bound systems consisting of a compact object (either a neutron star or a black hole) and usually a non degenerate companion star, both rotating ...
Evolution of the Magnetic Ground States with Lattice Distortion and Chemical Inhomogeneity in Doped Perovskite Oxides
(2018-04-18)
The physics of doped transition metal perovskite has been an area of intense research in the last few decades due to their interesting magnetic and transport properties. Various exciting phenomena such as, colossal magneto ...
Magnetic and Magnetotransport Studies in Transition Metal Oxides : Role of Competing Interactions
(2018-04-12)
There was a fame time for silicon in condensed matter physics, then the graphene era came and now topological insulators are gaining lot of attention, but magnetism in condensed matter physics has remained always fascinating ...
