CHEM30310 Soft Matter & Interfacial Chemistry

Academic Year 2021/2022

The first part of the module module covers the key topics of colloid and surface chemistry and provides the fundamental principles of supramolecular architecture and molecular self-assembly. It includes the following subjects: modern laboratory techniques for analysis of molecular assemblies, polymers and polymer nano-assemblies, gels, dispersions and emulsions; hydrophobic effects and hydrophobic interactions, surfactant self-assemblies (micelles and bilayer membranes, phase transitions in bilayer membranes); the role of surface tension in stability of nano-assemblies; Brownian motion; nano-encapsulation, delivery systems and other nano-formulations in biotechnology, food, pharmaceutical and other industries.
In the second part, the factors that affect the rates of chemical reactions are reviewed and specific examples of reaction mechanisms, including unimolecular, polymerization and photochemical reactions, are discussed. The ability to determine the expressions for the rate laws of complex reactions will be considered in detail. Both Steady State and pre-equilibrium approaches will be considered. Non-chain reactions will be introduced and expanded to the treatment of radical reactions, linear and branched chain reactions will be explored including explosions, as well as the mechanisms of reversible reactions. Unimolecular reactions and third body collisions will also be examined. Specific examples of atmospheric photochemistry and radical reactions of ozone will be reviewed. The kinetics of excited state processes will be considered in terms of fluorescence and the Stern Volmer treatment will be considered. The importance of collision theory will be introduced. Experimental methods for kinetic studies will be reviewed.
