Institute for Materials Research

Leeds Electron Microscopy and Spectroscopy Centre

LEMAS houses a large proportion of the electron microscopy and analysis facilities at the University of Leeds. Situated in the School of Process Environmental and Materials Engineering, it is jointly run by the Institute for Materials Research and the School of Earth and Environment.

LEMAS is internationally renowned as a leading research centre in Microscopic and Spectroscopic Characterisation of solid materials.

We aim to develop and underpin Materials Characterisation techniques in the university and to also offer external services to outside Higher Education institutions and industry.

The characterisation of the morphology, structure and chemical composition of materials at length scales, which can be as small as atomic dimensions constitutes a key aspect in understanding both a material's physical behaviour, such as the electronic, thermal, magnetic and mechanical properties, and its chemical behaviour.

Materials Characterisation lies at the interface between the physical and engineering sciences, it also increasingly covers many areas of the biological sciences. The major technological advances throughout history have been dependent on an accurate characterisation of the structure and chemistry of both traditional, improved and novel materials.
