Materials science is a cross-disciplinary subject closely related to engineering and chemistry and focussed on the design and modification of materials to improve their performance. Materials scientists use phase diagrams and techniques such as crystallography to study structure and understand how that leads to properties such as strength and durability. Forensic engineering is a branch of materials science that focusses on detecting and predicting the origins of mechanical failure in materials and help prevent accidents and disasters.
The job of materials science is to revolutionise technology. One very popular field is nanotechnology; nanomaterials may be used in electrical and optical applications, drug delivery in medicine and environmental clean up. Amongst the greatest challenges of materials science are the discovery of new materials that replace scarce materials in existing applications, and the search for high temperature superconductors from which we can develop magnetically levitating transport.
