Three distinct aspects, disorder, polymorphism and co-crystal formation have been addressed in molecular crystals in terms of intra- and intermolecular interactions involving halogens, weak hydrogen bonds and van der Waals ...

Organic light-emitting diodes (OLEDs) are emerging to replace conventional lighting technology due to their flexible device structures, multicolour emission, and ease of fabrication. However, one of the key challenges in ...

Supramolecular gels are soft materials consisting of a solid three-dimensional network with noncovalent interactions such as hydrophobic interactions, hydrogen bonding, cation-п, and п- п interactions. Due to their soft, ...

Semiconductor nanocrystals with sizes comparable to the corresponding bulk excitonic diameter exhibit unique size-dependent electronic and optical properties resulting from quantum confinement effect. Such nanocrystals not ...

Materials when subjected to deformation exhibit unstable plastic flow beyond the elastic limit. In certain range of temperature and strain rates many solid state solutions, both interstitial as well as substitutional, ...

This thesis presents our recent study of few interesting problems involving activated processes. This chapter gives an overview of the thesis. It is now possible to do single molecule experiments involving enzyme molecules. ...

The photodissociation dynamics of alkyl iodides in their A?band of absorption (arising from n ? ?* transition) has been of interest for dynamicists for the past three decades, starting from the pioneering work of Kasper ...

In this thesis, I use the quantum mode coupling theory (QMCT) formulation to study the dynamics in a supercooled liquid to understand how quantum fluctuations affect the liquid-glass transition. I calculate the Kubo-transformed ...

Inexhaustible solar energy, which provides a clean, economic and green energy, seems to be an alternative solution, for current and future energy demands. Harvesting solar energy presents a challenge in using eco-friendly, ...
