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 ...
Synthesis, Optical And Photoelectrical Investigations On PbS nano-,micro-structures
(2010-10-21)
The thesis describes the synthesis of PbS nano-, micro-structures by colloidal and hydrothermal techniques. Size and morphology dependent luminescence studies were carried out in detail. Application oriented studies like ...
Generalizations Of The Quantum Search Algorithm
(2010-12-03)
Quantum computation has attracted a great deal of attention from the scientific community in recent years. By using the quantum mechanical phenomena of superposition and entanglement, a quantum computer can solve certain ...
Understanding the Behavior of the Sun's Large Scale Magnetic Field and Its Relation with the Meridional Flow
(2018-07-05)
Our Sun is a variable star. The magnetic fields in the Sun play an important role for the existence of a wide variety of phenomena on the Sun. Among those, sunspots are the slowly evolving features of the Sun but solar ...
Understanding DNA-Based Nanostructures using Molecular Simulation
(2018-05-14)
Deoxyribonucleic acid (DNA) is arguably the most studied and most important biological molecule. Recently, it has also been established as a potential candidate for nanoconstruction. Self-assembly of DNA molecules has ...
Establishing Super- and Sub-Chandrasekar Limiting Mass White Dwarfs to Explain Peculiar Type La Supernovae
(2018-06-23)
A white dwarf is most likely the end stage of a low mass star like our Sun, which results when the parent star consumes all the hydrogen in its core, thus bringing fusion to a halt. It is a dense and compact object, where ...
Growth, Structural And Physical Properties Of Certain Antimony Based III-V Diluted Magnetic Semiconductors
(2010-07-20)
Semiconductor devices are the building blocks of electronics and communication technology in the modern world. The charge, mass and spin of charge carriers in the semiconductor devices lay the foundations of the technology ...
Charge Transport In Transparent Single-Wall Carbon Nanotube Networks And Devices
(2010-06-02)
Carbon nanotubes show a wide range of transport behavior that varies from ballistic to hopping regime, depending on the nature of disorder in the system. Minute variations in disorder can lead from weak to strong localization, ...
Magnetization, Magnetotransport And Electron Magnetic Resonance Studies Of Certain Nanoscale Manganites
(2010-06-15)
Perovskite rare-earth manganites of the form R1-xAxMnO3 (R – rare earth ion or Bi, A – Ca,Sr) have drawn an overwhelming research interest during the last few years owing to their extraordinary physical properties. Some ...
