Reflections: tales from within the crystal

School of Chemistry, The University of Melbourne, Parkville, Victoria, Australia

Crystals have long captivated humankind, from ancient healing remedies and myth and legend, to modern fashion trends and industrial applications.

Scientific interest in crystals was piqued over 400 years ago by Johann Kepler who detailed the beautiful symmetry of ice crystals. By the 20th century, scientists discovered that X-rays could be used to determine the arrangement of the atoms which comprise the crystal, creating the field of Crystallography.

This exhibition celebrates the International Year of Crystallography bringing together crystal specimens, models and instruments used throughout history to solve the mysteries that lie within the crystal.

Event Name The Role of Magnetic Symmetry in the Description and Determination of Magnetic Structures
Start Date 14th Aug 2014
End Date 16th Aug 2014
Duration 3 days
Description

Venue: Brockhouse Institute for Materials Research, McMaster University, Hamilton, Canada (near Toronto)

Focus: Lecture presentations and hands-on workshop tutorials will focus on the role of magnetic symmetry in the solution and refinement of magnetic structures.  This will include discussions of magnetic neutron diffraction, the proper description of a magnetic structure (e.g. supercell, wave or irrep-mode parameters), magnetic space groups and superspace groups, magnetic systematic absences, the use of symmetry operators to constrain magnetic models, and the use of symmetry in widely-available structure solution/refinement packages.

Target Audience:  Because many of the methods and tools for applying magnetic symmetry to the solution and refinement of commensurate and incommensurate magnetic structures are relatively new and developing rapidly, this workshop will be of interest to experts and novices alike.  Students, post-docs, faculty and industrial scientists with a strong interest in the crystallography of magnetic materials should plan to attend.  We anticipate between 30 and 50 participants.

Event Name Topological methods for expert systems in materials science
Start Date 12th Aug 2014
End Date 16th Aug 2014
Duration 5 days
Description The main goal of this school is to give an introduction to this whole new area that we call Topological Crystal Chemistry and to show how the topological methods and tools can be used for creating expert systems in materials science. There will be large time dedicated to hands-on session on the use of the novel and still not so widespread computer methods/software/databases so the student at the end of the course should be able to analyse any kind of extended structure through the eye of the topology and describe it in term of nets, entanglements, catenation etc. A special attention will be paid to the analysis of various classes of crystalline materials, in particular, MOFs, supramolecular crystals, zeolites, fast-ion conductors, minerals. All participants will have an ability to analyze their own crystal structures with the help of tutors that will be available also in the evening time. A special session will be devoted to summarize the results of such personal/free works.

The tutorial will start with a theoretical introduction where the background of the topological methods will be briefly, but rigorously, considered. No special mathematical skills are required, but the participants have to be aware of crystal chemistry and crystallography basics. The main abilities, problems, and perspectives of topological analysis of crystalline networks will be outlined.

The main part of the tutorial will be devoted to practical works with the computer programs TOPOS ( http://www.topos.samsu.ru/ ), Systre, and 3dt ( http://www.gavrog.org/ ) with a special attention to TOPOS.

Event Name Virtual Conference on Computational Chemistry
Start Date 1st Aug 2014
End Date 31st Aug 2014
Duration 31 days
Description

The first Virtual Conference on Computational Chemistry (VCCC-2013) was held from 1st to 31st August 2013. Following the success of this conference, we are now planning for the second virtual conference, VCCC-2014, from 1st to 31st August 2014.

Chemistry is no more about test-tubes and experiments but it also involves the use of efficient and accurate computational methods.

This virtual conference will also be held as part of the International Year of Crystallography. Computational chemistry is also used to complement research involving crystallography.

ICT can be used effectively for conferences and thus, virtual conferences have gained popularity. The major advantage of virtual conference is the lower cost involved for participation. One simply has to have access to the Internet or email to be involved in the conference.
