This course is a broad introduction to this interdisciplinary field based on processes and colloidal phenomena at interfaces, viz. gas-liquid, gas-solid, liquid-liquid, liquid-solid and solid-solid. Taking a genuinely applied approach, with applications drawn from a wide range of industries, we will attempt to meet your demands of working in the field. The course will, therefore introduces you to a wide range of real industrial examples. These examples range from water treatment through to soil management as well as examples taken from the coatings, detergency, ore flotation and photographic industries. To understand the course better, some of the more demanding mathematical derivations will be treated in a more subtle manner. With carefully structured units, starting with an introduction, and practice questions, this course is invaluable for undergraduates like you taking a first course on colloid and surface chemistry.

This course covers the basics of modern cryptography as used to secure e-commerce transactions and code distributed over the Internet. The course covers cryptographic primitives used for encryption and authentication; it also explains how these primitives are used to improve the security of applications. Emphasis is placed on what problems cryptography can solve. The overall aim of this course is to explore the various encryption and decryption techniques that can be applied to secure various e-commerce applications. The emphasis is on gaining an understanding of the concepts, the practical usability, and the vulnerabilities of different methods in cryptology.

The course is designed to expose students to the theory and applications of game theory, queuing models, inventory and network optimisation.
