The present thesis deals with different aspects of the chemistry of iron complexes, their interaction with DNA and photo-induced cleavage of double-stranded DNA. Chapter I presents a general introduction on metal-based ...

Biological processes at the cellular level take place in heterogeneous environments, and usually involve only a small number of molecules. They tend to exhibit strong time dependent fluctuations, as a result, and are, ...

Several organic transformations are mediated by group(IV) metal alkoxides. The reactivity is based on the basic nature of alkoxide group, Lewis acidic nature of the group(IV) metals, insertion of unsaturated molecules into ...

Although considered as a poison for long time, the importance of selenium as an essential trace element is now well recognized. In proteins, the redox active selenium moiety is incorportated as selenocysteine (Sec), the ...

The knowledge of geometry of molecular complexes formed via molecular association in solution through weak interactions is always important to understand the origin of stability and function of an array of molecules, ...

Atoms construct the molecules and molecules construct the material substances (with the exceptions as well, e.g.., metals, where atoms directly construct the material substances). Intermolecular interactions play an important ...

Electrical double-layer formed at the interface between an electrode and an electrolyte has been a topic of innumerable studies. The electrical interface plays a crucial role in kinetics, mechanisms and applications in ...

This thesis reports the theoretical investigations aimed at understanding the structure, stability and properties of a few inorganic compounds. The first chapter presents an introductory overview of the theories used to ...

In the thesis work we investigate four problems connected with dynamical processes in condensed medium, using different techniques of equilibrium and non-equilibrium statistical mechanics. Biology is rich in dynamical ...

In recent years, coinage metal nanoparticles have emerged as materials with largest quadratic optical nonlinearity. Their first hyperpolarizabilities (β) are very high (105-106 x 10-30 esu) but such large values were quite ...
