Single Crystal X-ray Crystallography

The group is led by Professor Judith A. K. Howard and has a wide range of materials-based research interests. These include experimental charge density analysis, in-situ crystallisation of liquids, ultra-low temperature crystallography, high pressure crystallography, software development, solid-state reactions the study of non-linear optical materials and magnetically interesting materials. In addition,Dr. D.S.Yufit is the contact point for the departmental crystallography service, which is run with the help of all members of the group. Commercial work can also be undertaken.
