Module aims
This module builds on the knowledge established in Year 1 of the Chemistry programme. It introduces students to the way in which modern materials have changed our lifestyle beyond recognition, providing an insight into the cutting edge of materials chemistry and how it underpins the technological developments expected in the 21st century. The module focuses in particular on how the molecular structure controls the materials properties and connects with real practical applications. The module introduces general aspects in the topic of materials science (structure and physical properties) and considers the origins of nanotechnology in colloid science. It then goes on to explore specific applications of modern materials, in LCD technologies, energy storage devices, and biomedical technologies . These concepts are followed by studying how nanotechnology is increasingly being integrated into modern advanced materials. In particular, the course will illustrate how developing materials with well-defined molecular nanostructures can lead to new types of behaviour and high-tech applications – for example in optical electronics, imaging and nanomedicine.

Module feedback
Students will receive feedback on their performance in their assessed workshop within 4 weeks. Oral feedback for the formative workshops will be given during the sessions.
Closed exam results with per-question breakdown are returned to the students via supervisors within 5 weeks (as per special approval by the University Teaching Committee). Outline answers are made available via the Chemistry web page when the students receive their marks, so that they can assess their own detailed progress/achievement. the examiners' reports for each question are made available to the students via the Chemistry web pages.
Indicative reading
To be provided by individual tutors: this is a research-led course so up-to-date scientific publications will form the majority of the reading.
