flagThe triennial congress of the International Union of Crystallography was held in Montreal over 8 days in August 2014.

Contributions to the meeting from Chem. Cryst. staff and students included:

Richard I. Cooper and James A. Arnold:
Displacement Parameter Restraints for Dealing with Limited Data

Karim J. Sutton, Pascal Parois and Richard I Cooper:
Big Methods for Small Molecules

Jerome G. P. Wicker and Richard I. Cooper
Predicting crystallisation propensity of small molecules

Pascal Parois and Richard I. Cooper
Effective data collection and refinement of perturbed structures

Richard Cooper and Lukas Palatinus co-chaired a session on “New Techniques for Structure Solution and Refinement”

Material from Oxford Chemistry’s Crystals at the Garden exhibition held earlier this year was displayed as part of a public International Year of Crystallography exhibition which ran alongside the main meeting.

A screening of Georgina Ferry’s play “Hidden Glory: Dorothy Hodgkin in her own words” was organized during the meeting, supported by Oxford Chemistry, Somerville College, and the British Crystallographic Association. It was well attended by meeting delegates including some of Dorothy’s former students.

This version has been superseded by v1461.

v1460The CRYSTALS v1460 installer is now available.

This release is built with a new compiler and libraries – therefore please report any installation or usage problems should they occur.

Changes
Pascal has significantly improved speed and precision of least squares refinement.
Improvements to Hooft / Parsons parameter calculations.
Options to standardise position in cell close to 1/2 1/2 1/2
Ability to restrain just NH,OH or all-H atoms (as recommended by CheckCIF).
Fix ‘Open Crystals Here’ context menu link on Windows 7 & 8: right-click on a folder, or on the background of the current folder.
Histogram of systematic absence values added to analyses window
Many small fixes to diffractometer import software
Scripts by Markus Neuburger to automatically refine occupancies of disordered parts.
Improved support for importing SHELX res files
Cell esd calculation in CIF fixed to agree with Platon method.
Added internal editor for editing constraints, restraints, etc.
Fix generation of space group operators from non-standard monoclinic groups F2/d, B2/d, B21/d and related symbols.
Many other bug fixes and tweaks.

IMG_20120706_132314The sixth X-ray diffraction school organised by Universite de Lorraine and CNRS will be held in early July at the Abbaye des Prémontrés Pont à Mousson, France. The historical setting on the banks of the Moselle River is the backdrop for an intensive week of crystallography. Richard Cooper will lecture on “Affinement de structures cristallines” and engage the audience with some “Travaux Practiques” using the CRYSTALS refinement package.

Congratulations to Karim Sutton, Jerome Wicker and Rajiv Gogna from Chem Cryst, together with some guy from engineering, for making it to the finals of the 2014 University inter-college croquet tournament. This is a truly ridiculous feat and we wish them the best of luck next year!

dorothy hodgkinAs part of the Crystals at the Garden exhibition, on Wednesday 25th June there will be a screening of the film of Georgina Ferry’s play “Hidden Glory: Dorothy Hodgkin in her own words” staring Miranda Cook. The screening will be followed by a guided tour of the exhibition and Botanic Gardens led by researchers from the Department of Chemistry.

Date: Wednesday 25th June 2014 from 5.30 – 8pm

calciteAn exhibition is running at the University of Oxford Botanic Garden throughout June and includes crystals, lab equipment, and stories of cutting edge and historical science from the Department of Chemistry and the Chemical Crystallography group.

Open until June 27th 2014 – all ages welcome. Free with admission to the Garden (admission is free for Oxford students and staff, children are free with an adult – see the Botanic Garden website for more information). The exhibition is open during normal Botanic Garden opening hours 9am – 6pm (last entry 5.15pm).

Head of Department, Professor Tim Softley, unveils the RSC Chemical Landmark Award

The Royal Society of Chemistry has awarded a new National Chemical Landmark blue plaque to the University of Oxford Inorganic Chemistry Laboratory, to celebrate the 50th anniversary of Britain’s only female Nobel Prize winner and to coincide with the UN International Year of Crystallography 2014.

Dorothy Hodgkin won the Nobel Prize “for her determinations by X-ray techniques of the structures of important biochemical substances”, including the structures of the antibiotic penicillin and vitamin B12, a treatment for pernicious anaemia, thereby augmenting the synthesis and production of these compounds. Later she and her colleagues also determined the structure of insulin, the hormone responsible for carbohydrate metabolism and employed therapeutically in the management of diabetes.

The occasion was marked with a special symposium in the Inorganic Chemistry Laboratory featuring lectures by Professors Susan Lea , Paul Raithby and Andrew Goodwin discussing their work in the field of crystallography, and how the field has changed in the 50 years since Hodgkin’s Nobel Prize. Science writer Georgina Ferry, who wrote a biography of Dorothy Hodgkin and the play, Hidden Glory, outlined Dorothy Hodgkin’s journey to the Nobel Prize.
The audience included current staff and students from across the University, as well as some of Dorothy’s family, colleagues and former students.

Professor Tim Softley, Professor Philip Mountford, Ms Georgina Ferry, Professor Susan Lea, Professor Paul Raithby, Dr Robert Parker, and Professor Andrew Goodwin

Hands-on activities were run by Diamond Light Source (including their lego beamline), volunteers from the Solar Fuels outreach team from Chemistry and live crystal growing expertly run by Jonny Brooks-Bartlett and Katharina Jungnickel, graduate students in Biochemistry.

Their were also four 30-minute ‘popup’ talks in the basement gallery from Brian Sutton (King’s College London) on crystal symmetry and diffraction; a tale of persistence to overcome ‘Mission Impossible’ – growing some virus protein crystals by Elspeth Garman (Biochemistry); Pasteur, Penicillin and Point Groups by Richard Cooper (Chemistry) and Dorothy Hodgkin: A life by Georgina Ferry, Dorothy’s biographer.
