Role Of Surface And Inter-particle Spacing On Optical Properties Of Single And Hybrid Nanoparticle Assemblies
(2013-07-03)
Optical properties of nanoscopic materials have been intensively perused over last couple of decades due to their tunable optical properties. Recent interests in this field have been mainly focused on the preparation of ...
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 ...
Probing Magnetic And Structural Properties Of Metallic Nanowires Using Resistivity Noise
(2013-07-19)
The main focus of this thesis work has been the study of domain wall (DW) dynamics in disordered cylindrical nanomagnets. The study attempts to accurately quantify the stochasticity associated with driven (temperature/magnetic ...
Conformation And Charge Transpsort In Conducting Polymers, Carbon Nanotubes And Their Nanocomposites
(2013-05-02)
The main motivation in this thesis is to compare the conformation and charge transport in conducting polymers and carbon nanotubes (CNTs) and to investigate those physical properties in their combined form of nanocomposites. ...
Magnetic And Transport Studies On Nanosystems Of Doped Rare Earth Manganites And VPP PEDOT
(2013-06-10)
The study of novel properties of materials in nanometer length scales has been
an extensive area of research in the recent past. The field of nanosciece and
nanotechnology deals with such studies and has gained tremendous ...
Photo And Thermal Induced Studies On Sb/As2S3 Multilayered And (As2S3)1-xSbx Thin Films
(2013-05-31)
Chalcogenide glasses have attracted considerable attention due to their infrared
transparency, low phonon energy, and high non linear optical properties. They have been
explored as promising candidate for optical memories, ...
Investigating Systematics In The Cosmological Data And Possible Departures From Cosmological Principle
(2013-06-11)
This thesis contributes to the field of dark energy and observational cosmology. We have investigated possible direction dependent systematic signal and non-Gaussian features in the supernovae (SNe) Type Ia data. To detect ...
Stability of Accretion Flows And Radiative-Hydrodynamics Around Rotating Black Holes
(2013-06-24)
In the case of cold accretion disk, coupling between charge neutral gas and magnetic field is too weak such that the magneto-rotational instability will be less effective or even stop working. In such a situation it is of ...
Numerical Study Of The Complex Dynamics Of Sheared Nematogenic Fluids
(2013-07-17)
In this thesis, we have tried to explain the regular and irregular(chaotic) dynamics of worm like micellar solutions on applying shear, through a detailed study of the equation of motion of a nematic order parameter tensor ...
