Search for Northern Hemisphere Rapidly Oscillating Ap stars
(Indian Institute of Science, 2005-04-20)
Rapidly oscillating Ap (roAp) stars are cool, magnetic, chemically peculiar A-F type stars which exhibit high frequency oscillations similar to that of the famous five minute oscillations of Sun. These oscillations are ...

(2009-08-19)
This thesis deals with the studies of magnetization and electrical transport properties of iron nanoparticles embedded in the carbon matrix. The synthesis and characteristics of the nanoparticle systems studied, are also ...
Light Scattering Investigations Near The Critical Point In Some Solvophobic Systems And The Design And Analysis Of A Microkelvin Thermostat For Critical Phenomena Studies
(Indian Institute of Science, 2007-05-21)
This thesis reports light-scattering experiments and visual investigations close to the critical point, in the solvophobic systems, 3-methylpyridine (3MP) + heavy water (D2O) + sodium bromide (NaBr) and methyl ethyl ketone ...
A Radio Study Of Gas Loss Processes In Nearby Galaxies
(2008-10-17)
The work in this thesis involves detailed multi-frequency radio continuum
(from 325 MHz to 15 GHz) and Hi spectroscopic studies of a few represent
tative nearby galaxies which are experiencing gas-loss from their disks ...
Quantum Information Processing By NMR : Relaxation Of Pseudo Pure States, Geometric Phases And Algorithms
(2009-04-13)
This thesis focuses on two aspects of Quantum Information Processing (QIP) and contains experimental implementation by Nuclear Magnetic Resonance (NMR) spectroscopy. The two aspects are: (i) development of novel methodologies ...
X-ray Crystallographic Studies Of Designed Peptides, Self Assembling Pseudopeptides And Molecular Modeling
(2009-03-04)
Structural studies of peptides has relevance for various applications, like, in de novo design of proteins, in designing better catalysts for organic synthesis, in structure based drug design, in the design and construction ...
Soft Matter : Routes To Rheochaos, Anomalous Diffusion And Mesh Phases
(2008-10-06)
Soft condensed matter (SCM) systems are ubiquitous in nature. SCM systems contain mesoscopic structures in the size range 10 nm to 1 am that are held together by weak entropic forces. These materials are therefore easily ...
Theoretical Investigations Of Core-Level Spectroscopies In Strongly Correlated Systems
(2009-03-11)
Ever since the discovery of exotic phenomena like high temperature (Tc) superconductivity
in the cuprates and colossal magnetoresistance in the manganites, strongly correlated electron systems have become the center of ...
Theoretical Investigation Of Relativistic Effects In Heavy Atoms And Polar Molecules
(2009-03-20)
Extensive theoretical studies on the ground and excited state properties of systems containing heavy atoms have shown that accurate prediction of transition energies and related properties requires the incorporation of ...
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 ...
