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 ... -
Molecular Construction Using Carbene and Diboron Systems: Catalytic Transformation of C-C and C-Hetero Atom Bonds
The thesis presents an unconventional approach for the molecular construction using carbenes as the carbon source, and water as the hydrogen source. A gold-catalyst has been used to transfer the carbenes to effect ... -
Molecular Dynamics Studies of Diffusion in Confined Regions
Diffusion of guest molecules under confinement of zeolites shows many interesting properties due to guest-host interactions. This thesis explores some of these interesting behaviours relating to the diffusion of guest ... -
