Anomalous Translational And Reorientational Dynamics Of Single File Water
(2010-04-12)
This thesis deals with several aspects of translational and reorientational dynamics of water molecules confined inside narrow carbon nanotubes. Water molecules confined in a non-polar, nanoscopic pore exhibit extremely ...
Effects Of Spin Polarization And Spatial Confinement On Optical Properties Of Bulk Semiconductors And Doped Quantum Wells
(2010-04-06)
We correlated experimental results with theoretical estimations of the dielectric function ε(ω) in two contexts: the effect of an electric field in quantum wells and that of the spin polarization of an interacting electron-hole ...
Understanding The Solar Magnetic Fields :Their Generation, Evolution And Variability
(2010-03-24)
The Sun, by the virtue of its proximity to Earth, serves as an excellent astrophysical laboratory for testing our theoretical ideas. The Sun displays a plethora of visually awe-inspiring phenomena including flares, ...
X-Ray Crystallographic Studies Of Designed Peptides : Characterization Of Novel Secondary Structures Of Peptides Containing Conformationally Constrained α-, β- And γ-Amino Acids And Polymorphic Peptide Helices
(2010-10-21)
Structural studies of peptides are of great importance in developing novel and effective biomaterials ranging from drugs and vaccines to nano materials with industrial applications. In addition, they provide model systems ...
X-ray Crystallographic Characterization Of Designed Peptides Containing Heterochiral And Homochiral Diproline Segments And Database Analysis
(2010-12-30)
Understanding the relation between amino acid sequences and protein structures is one of the most important problems in modern molecular biology. However, due to the complexities in the protein structure, this task is ...
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, ...
Phase Transitions And Relaxation Processes In Water And Glycerol-Water Binary Liquid Mixtures : Spin Probe ESR Sudies
(2010-11-18)
A liquid Cooled below its normal freezing temperature is known as a supercooled liquid. On further cooling, supercooled liquids crystallize to thermodynamically stable, ordered structures. Alternatively, if the cooling ...
Critical Behavior On Approaching A Double Critical Point In A Complex Mixture
(2010-08-25)
This thesis reports the results of light-scattering measurements and visual investigations of critical phenomena in the complex mixture 1-propanol (1P) + water (W) + potassium chloride (KCl) which has a special critical ...
Gravitational Waves From Inspiralling Compact Binaries : 3PN Polarisations, Angular Momentum Flux And Applications To Astrophysics And Cosmology
(2010-09-03)
Binary systems comprising of compact objects like neutron stars (NS) and/or black holes (BH) lose their energy and angular momentum via gravitational waves (GW). Radiation reaction due to the emission of GW results in a ...
An Investigation Of The Ferromagnetic Insulating State Of Manganites
(2010-09-22)
Electrical conductance in the ferromagnetic insulating (FMI) phase of manganites has been experimentally investigated. The investigations were performed on single crystals of compositions La0.82Ca0.18MnO3 and Nd0.7Pb0.3MnO3. ...
