Overlapping absorption edges will occur when an element is present in multiple oxidation states within a material. DetOx is a program for partitioning overlapping X-ray absorption spectra into contributions from individual atomic species and computing the dependence of the anomalous scattering factors on X-ray energy. … Read the rest
As part of the Bragg Centenary Celebrations, Melvyn Bragg and his guests discussed the history of crystallography, the study of crystals and their structure on “In Our Time” on BBC Radio 4. His guests were Prof. Judith A. K. Howard (University of Durham), Dr. Christopher Hammond (University of Leeds) and Prof. Mike Glazer … Read the rest
Every year, Oxford Inspires organises an evening of social and cultural events in the centre of Oxford following the theme of Christmas Lights. A lot of the institutions within the city get involved, and this year that included Amber, who was invited to give a presentation at the Snowflake exhibition held at the History of … Read the rest

The traditional Waser distance restraint, the rigid-bond restraint and atomic displacement parameter (ADP) similarity restraints have an equal influence on both atoms involved in the restraint. This may be inappropriate in cases where it can reasonably be expected that the precision of the determination of … Read the rest

Transition metal σ-alkane complexes are key intermediates in catalytic C–H activation processes. We have used a direct crystal to crystal transition, by reaction with H2, to produce an alkane σ-complex directly. This structure is of … Read the rest
