Metal Sulphide Based Semiconductors for Solar Photon Energy Harvesting
Sun light is a relatively infinite source of energy available on the earth compared to all other renewable and non-renewable energy sources put together. Harvesting solar photons in an effective and efficient manner can ... -
Metal-Organic Framework (MOF) Compounds : Synthesis, Structure, Sensing and Catalytic Studies
(2018-06-29)The metal-organic framework (MOF) compounds have witnessed rapid growth in the past decade and currently emerged as a highly unique area in the field of chemistry, materials science, and multiple branches of engineering. ... -
Metallo-β-Lactamase, Phosphotriesterase And Their Functional Mimics
(2011-01-11)Metallohydrolases with dinuclear-zinc active sites perform many important biological hydrolytic reactions on a variety of substrates. In this regard, metallo-β-lactamases (mβ1, class B) represent a unique subset of zine ... -
Methodological Developments in NMR for Chiral Analysis using Selective Excitation
The NMR spectroscopy as usually practiced in isotropic achiral solvents is unable to differentiate enantiomers, unless the intermolecular diastereomeric interactions are imposed with an enantiomerically pure reagent. Chiral ... -
Methylammonium Lead Iodide thin lms grown by Pulsed Laser Deposition for Photodetector Applications
This thesis studies the fabrication and characterization of Methylammonium Lead Iodide perovskite thin films for photodetector applications. Unlike, any other perovskite halide material, Methylammonium Lead Iodide perovskite ... -
Micro-spectroscopic studies on Mycobacteria & Cancer cells
Evasion of the immune system is a key hallmark of cancer progression. Developing strategies that diagnose early the immune-cancer synapse may lead to long term cures from these aggressive cancers. We aimed to develop optical ... -
Microscopic Investigations of Dynamics of Linear Diatomics and Ions in Water and Aqueous Binary Mixtures
This thesis explores the structural and dynamical aspects of small, charged and neutral, solute molecules in both pure water and in aqueous binary mixtures, with emphasis on water-ethanol binary mixture. We employ both ... -
