This module is mutually exclusive with

PEME5711MMaterials Structures and Characterisation

This module is not approved as a discovery module

Objectives

The objectives of this module are to:
- provide the scientific basis for the relationship between the physical properties of materials and their structure;
- demonstrate and apply an understanding of the principles of function and manufacturing of materials used in the functional materials industry.

Learning outcomes
At the end of this module, students should:
- understand the influence of composition and structure on the physical and thermal behaviour of materials by applying classical and quantum mechanical approaches;
- understand the historical development of functional materials to satisfy the needs of different industrial sectors;
- appreciate the significance of market pull and technology push in the development of novel functional materials;
- understand the limitations on the properties which may be obtained in particular materials classes;
- be able to recognise and interpret microstructures in a range of functional materials and account for their development;
- understand the exploitation of the process-microstructure-properties relationship in materials science in the design of functional materials with an appropriate combination of properties;
- understand the complex materials issues involved in producing integrated functional devices and be able to offer solutions to problems which may arise;
- be aware of current developments in materials science in the functional materials sector and its potential impact on design and technology;
- survey and critically evaluate scientific literature relating to the above.

Skills outcomes
The main skill acquired will be the ability to propose strategies for engineering of functional materials to achieve optimum performance for given applications.
