Thermal and Femtosecond Laser-Induced CO2-Surface Chemistry on Supported Iron-Oxide Based Nanoparticle Surfaces under UHV
The thesis has been presented in two parts. The 1st part of the thesis focuses on the fundamental understanding of room temperature CO2 adsorption on iron-oxide based NP surfaces. The 2nd part describes the understanding ... -
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 ... -
Vibrational Spectroscopic studies of Dynamics of BSA unfolding, Lysozyme-Ethanol interaction and Tissue Imaging
Vibrational spectroscopy has served as a powerful tool for understanding various structural properties of the molecules since decades. In the recent years, it has also emerged as an invaluable tool in understanding various ... -
Nonequilibrium dynamics and thermodynamics of some single-particle activity-induced diffusive systems
In the mesoscopic world, diffusion is a ubiquitous process and it is usually explained by the Einstein’s theory of Brownian motion (BM). However, in the biological systems, some peculiar dynamical behaviors are observed ... -
Carbon aerogel supported first-row transition metal catalysts for methanolyis of ammonia borane
Ni-Ni3B, Co-B, and Co-Ni-B nanocomposites decorated on carbon aerogel were successfully synthesized by adopting the solution impregnation method. The nanocomposites were characterized by powder XRD, transmission electron ... -
Design, Synthesis and Optical Characterization of Thiophene Based Luminophore
We successfully designed and synthesized a series of thiophene based luminophores. We were able to modulate the optical band gap of these luminophores by systematically fine-tuning the chemical structure of these compounds. ... -
Rotational Spectroscopic and Computational Studies on Inter/Intramolecular Bonding
The importance of non-covalent interactions cannot be undermined, as it permeates nearly every sphere of chemistry. The hydrogen bond is the most well-known and ubiquitous non-covalent interaction. In recent times similar ... -

Catalytic Studies with Ru and Ir Half-sandwich Complexes Bearing NHC Ligands
The thesis describes the study of arene-tethered and untethered Ru half-sandwich complexes as catalysts in the addition of hydroelements (E‒H, E = H, B, Si) across unsaturated C-C, C-N and C-O bonds and transfer hydrogenation ... -
Reversible Redox Switching of First Hyperpolarizability (Β) of Metallorganic Complexes
The concept of molecular switches has garnered enormous interest because of the vital role of these switches as components in molecular electronic/photonic devices, signal transmission and optical communication. Compounds ... -
Structure-Activity Correlation and Mechanistic Investigations of Glutathione Peroxidase-Like Catalytic Activity of Diaryl Diselenides
Hydroperoxides are very harmful and they can oxidize several biomolecules, causing different disease states. Glutathione peroxidase (GPx) is a mammalian selenoenzyme which protects human body from oxidative damage by ... -
Syntheses and Structure Elucidations of Co-crystal with Nicotinamide Co-former
Abstract : Co-crystals consist of two or more components that form a unique crystalline structure having unique properties. The components interact via non-covalent, ionic interaction, van der Waals interactions and π-π ... -
Organic Transformations in the Confined Cavity of Self-Assembled Pd(II) Molecular Containers
Biological systems utilize its extraordinary ability to develop complex and functional molecular assemblies employing reversible non-covalent interactions. These natural aesthetic examples motivated synthetic chemists ... -
