Doping And photophysical Properties Of II-VI Semiconductor Nanocrystals
(2010-06-03)
Semiconductor nanocrystals with sizes comparable to the corresponding bulk excitonic diameter exhibit unique size-dependent electronic and optical properties resulting from quantum confinement effect. Such nanocrystals not ...
Gas Phase And Electrocatalytic Reaction Over Pt, Pd Ions Substituted CeO2, TiO2 Catalysts and Electronic Interaction Between Noble Metal Ions And The Reducible Oxide
(2010-06-02)
Among the various heterogeneous catalytic reactions three way catalysis (TWC), catalytic combustion of hydrogen, water gas shift reaction (WGS) and preferential oxidation of CO (PROX) in the hydrogen rich stream are some ...
Synthesis, Characterization, Properties And Growth Of Inorganic Nanomaterials
(2010-06-03)
The thesis consists of eight chapters of which the first chapter presents a brief overview of inorganic nanostructures. Synthesis and magnetic properties of MnO and NiO nanocrystals are described in Chapter 2, with emphasis ...
Structure And Dynamics Of Constrained Water : Microscopic Study Of Macromolecular Hydration Using Computer Simulations
(2010-06-04)
The thesis, which contains nine chapters, reports extensive large scale atomistic molecular dynamics (MD) simulation studies of water structure and dynamics at the surface of an anionic micelle, hydration layer of two ...
Spectral Simplification In Scalar And Dipolar Coupled Spins Using Multiple Quantum NMR : Developments Of Novel Methodologies
(2010-07-28)
Spin selective MQ-SQ correlation has been demonstrated by either selective pulses in homo-nuclear spin systems in isotropic and weakly orienting chiral media or by nonselective pulses in hetero-nuclear spin systems in ...
Investigation Of Electronic Structure Of Transition Metal Oxides Exhibiting Metal-insulator Transitions And Related Phenomena
(2010-07-26)
Transition metal oxides have proven to be a fertile research area for condensed matter physicists due to the fascinating array of superconducting, magnetic and electronic properties they exhibit. A particular resurgence ...
Investigations On Size Dependence Of Diffusivity In Condensed Media
(2010-08-24)

Synthesis, Structure And Redox Catalytic Properties Of Pt And Pd Ion Substituted Ce1-xMxO2(M= Ti, Zr & Hf) Oxygen Storage Capacity Nano-materials
(2010-09-28)
Three-way catalysis (TWC) involves simultaneous removal of the three pollutants (i.e., CO, NOx, and HCs) which led to the branch of auto-exhaust catalysis. CeO2 has become the main component of TWC catalyst because of its ...
Theoretical Approaches For Modelling Molecular Magnetism
(2010-10-05)
In this thesis we have developed electronic and spin model Hamiltonians to understand magnetism in molecule based magnets like photomagnets, high-nuclearity transition metal complexes and single molecule magnets.
In ...
