Origin Of The Extragalactic Gamma-Ray Background
(2013-10-01)
It is evident that the origin of EGRB is not well established. In this thesis I examine the unresolved discrete origin of EGRB. The contribution from normal galaxies, starburst galaxies and AGNs to the EGRB is examined. ...
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 ...
Studies Of Diffuse Ultraviolet Radiation
(2013-10-07)
Ever since the first observations of diffuse ultraviolet radiation by Hayakawa et al. (1969) and Lillie & Witt (1976), there has been an effort to understand its distribution and its origin. Unfortunately, because of the ...
Crystal Structure Of Mycobacterium Tuberculosis Histone Like Protein HU And Structure Based Design Of Molecules To Inhibit MtbHU-DNA Interaction : Leads For A New Target. Structure Aided Computational Analysis Of Metal Coordinated Complexes Containing Amino Acids And Organic Moieties Designed For Photo Induced DNA Cleavage
(2015-08-17)
In bacteria, nucleoid associated proteins (NAPs) represent a prominent group of global regulators that perform the tasks of genome compaction, establishing chromosomal architecture and regulation of various DNA transactions ...
Pulsed Laser Ablated Dilute Magnetic Semiconductors and Metalic Spin Valves
(2018-04-02)
Spintronics (spin based electronics) is a relatively new topic of research which is important both from the fundamental and technological point of view. In conventional electronics charge of the electron is manipulated and ...
Modelling, Fabrication and Characterization of HgCdTe Infrared Detectors for High Operating Temperatures
(2018-02-23)
In this work, we have designed, simulated, fabricated and characterized homojunction Hg1-xCdxTe detector for high operating temperature in the MWIR region. The IR photon detectors need cryogenic cooling to suppress thermal ...
Role of Excess Fe in Pristine and Substituted Fe Chalcogenide Superconductors
(2018-03-02)
Fe chalcogenides : The discovery of superconductivity in Fe based compounds trig-
gered an intense research activity in this field with significant importance given to
material synthesis. As a result, numerous materials ...
Investigations of Phase Change Memory Properties of Selenium Doped GeTe and Ge2Sb2Te5
(2018-04-05)
GeTe and Ge2Sb2Te5 alloys are potential candidates for non-volatile phase change
random access memories (PCRAM). For electrical data storage applications the materials should have stable amorphous and crystalline phases, ...
Development of a Spin-Polarized Low Energy Electron Diffraction System and Investigation on Spin-Orbit and Exchange Interactions on Ir(100) and Ultrathin Fe(100) Grown on Ir(100)
(2018-02-28)
Spin-polarized electron beam has not yet been produced from an unpolarized electron beam using Stern-Gerlach type spin filter, because of the Lorentz force and Heisenberg uncertainty principle. At present, electron spin ...
The Many Facets of Variabilities in X-ray Binaries
(2018-02-28)
More than half a decade of X-ray astronomy with various balloon borne and space orbiting X-ray instruments, have led to discoveries and detailed studies of X-ray binaries. An important property of X-ray binaries is intensity ...
