Investigation of Optical and Electro-optical Effects at Material Interfaces
The key questions addressed in this thesis are related to light-matter interactions at the material interfaces and are related to both plasmonic as well as Pockels effects. Plasmonics enables the design of compact photonic ... -
Investigation Of Phase Separation In Bulk Heterojunction Solar Cells Via Self-assembly Approach And Role Of Organic Fluorine In Design Of n-type Molecular Semiconductors
(2014-05-01)The present thesis is focused on rational design and synthesis of π-conjugated donoracceptor-donor (D-A-D) type oligomers and D-A type copolymers. Thesis is organized in seven chapters, apart from introduction remaining ... -
Investigation of Plug Nozzle Flow Field
(2018-03-21)Plug nozzle, a passive altitude adaptive nozzle, for futuristic SSTO applications, exhibits greater efficiency as compared to conventional nozzles over a wide range of altitudes. The plug nozzle comprises of a primary nozzle ... -
Investigation of Psychrophilic SUMO Proteases: Towards a More Efficient SUMO Protease at Lower Temperature
Covalent attachment of the fusion protein, Small Ubiquitin-like modifier (SUMO), to recalcitrant target proteins (especially transmembrane proteins) make purification of the target protein much easier by enhancing its ... -
Investigation of quantum interference and quantum oscillations in 3D topological insulators
The investigations on the topological phase of the matter first started with the experimental discovery of the quantum Hall effect (QHE) back in 1980. The experimental discovery of the quantum spin Hall effect (QSHE) was ... -
Investigation of RAG1 in lymphoid and brain cells: Understanding mechanism and regulation
In summary, we show that RAG1 expression is regulated through a novel miRNA (miR- 29c) mediated mechanism and establish that as an additional mode of RAG1 regulation. Studies described in the thesis reveal that among the ... -
Investigation Of Ramp/Cowl Shock Interaction Processes Near A Generic Scramjet Inlet At Hypersonic Mach Number
(2010-08-05)One of the major technological innovations that are necessary for faster and cheaper access-to-space will be the commercial realization of supersonic combustion jet engines (SCRAMJET). The establishment of the flow through ... -
Investigation of strongly correlated paramagnetic state at sub-Kelvin regime for S ≥ 1/2 systems: Role of disorder and dimensionality
A magnetic system usually orders ferro- or anti-ferromagnetically at temperatures comparable to interaction strength between the spins. Moreover, an interacting spin system tends to order with the increase of dimensionality ... -
Investigation of Structural and Electronic Aspects of Ultrathin Metal Nanowires
(2018-02-11)The constant trend of device miniaturization along with ever-growing list of unusual behaviour of nanoscale materials has fuelled the recent research in fabrication and applications of ultrathin (~2 nm diameter) nanowires. ... -
Investigation of Structural relaxation in IV - V -VI Chalcogenide glasses for Infrared applications
Chalcogenide glasses are well known for their application in infrared transmission and sensing. These glasses are usually prepared by quenching the melt. The arrangement of atoms in the liquid state gets arrested into ... -
