IUCr Associates Programme

IUCrAssociates_right_squareThe IUCr is excited to announce its new, voluntary Associates Programme. This will launch officially at the IUCr Congress in Hyderabad in August 2017.

The programme offers a series of benefits and tools to help you network, share ideas and discover more about crystallography. In addition, by joining the IUCr Associates Programme you will be supporting the IUCr in its many charitable activities such as sponsoring international meetings and schools, and its OpenLabs initiative.

The benefits of joining include, for example, a 20% discount on the open-access fee for publishing an article in an IUCr journal, the facility to download 6 free articles from Crystallography Journals Online, a 50% discount for individuals purchasing the print version of International Tables for Crystallography, and many others.

There will also be tools for professional networking such as access to the IUCr LinkedIn group, a jobs board and opportunities to participate in the IUCr Outreach and Education programme.

The Associates Programme welcomes individuals at any stage of their career, from undergraduates to postdoctoral and senior researchers (a reduced joining rate is available for students and retired scientists).

The IUCr is offering a pre-launch discount of 20% on the Associates Programme joining fee, which gives you access to all the benefits for a period of 3 years. Anyone signing up before the launch in August will be eligible for this specially discounted rate (USD 160 or USD 48 for students and retired scientists). For more details and to register your interest in this offer, please click here.

If you have any questions about the Associates Programme, please do not hesitate to contact us at associates@iucr.org

Special issue on halogen bonding

me0646There is a growing understanding in the scientific community that current scientific and technological challenges can only be efficiently met in a collaborative atmosphere and using multidisciplinary approaches. The field of halogen bonding became not just a hot research area, but also one known for its friendly openness to various scientific fields and approaches that may provide an improved understanding, a further development or an application to its central topic, the halogen bond. This welcoming openness has characterized and was well reflected by the contributions of the 2nd International Symposium on Halogen Bonding, ISXB-2, at which results from a number of fields including fundamental and computational chemistry, crystal engineering, biochemistry and molecular biology, liquid systems and applications were presented. In this special issue of Acta Crystallographica Section B, a selection of the research presented in 52 oral and 31 poster presentations of the symposium is provided for the reader, highlighting some of the main advances of this field.

It all started 200 years ago, when Jean-Jacques Colin described the formation of an iodine‚Äďammonia complex, involving an intermolecular interaction in which iodine acts as electron acceptor and the nitrogen of ammonia as electron donor. The composition of the complex was established by Fredrick Guthrie 50 years later, the nature of the interaction first understood by Robert Mulliken in the 1950s, and the interaction rationally applied first by Odd Hassel, winning him a Nobel Prize in 1969. Although some sporadic research addressed the behavior of this phenomenon, it only became intensely studied and its existence widely accepted over the past decade. Over the past years, the focus of its investigations started moving from crystallographic and computational studies aimed at fundamental understanding to its applications in chemistry and biology, for example for the improvement of synthetic techniques and the properties of bioactive substances. The aim of this special issue is to present examples of studies on the frontiers of halogen bonding. We present this issue with the hope that it will draw the attention of the broad scientific community and raise the interest of many to enter this exciting field and contribute to the upcoming 3rd International Symposium on Halogen Bonding, ISXB-3, which will take place in Greenville, USA, June 2018.

On this occasion we would like to thank all authors for their excellent contributions.

A large-solid-angle X-ray Raman scattering spectrometer

vv5158S. Huotari and co-workers [J. Synchrotron. Rad. (2017), 24, 521-530] describe an end-station for X-ray Raman spectroscopy at beamline ID20 of the European Synchrotron Radiation Facility. The end-station is dedicated to the study of shallow core electronic excitations using non-resonant inelastic X-ray scattering.

X-ray Raman scattering (XRS) spectroscopy is a versatile tool for studying shallow X-ray absorption edges using hard X-rays. It has proven to be an invaluable technique for the study of electronic excitations in a variety of sample systems such as crystals, liquids and gases. Over the past decades, XRS has been applied to solve geoscientific questions by studying shallow core edges under extreme pressure and temperature conditions, follow chemical reactions in situ, and study liquid samples under well defined thermodynamic conditions.

Journal of Applied Crystallography: Call for papers on advanced neutron scattering instrumentation

me0643Journal of Applied Crystallography invites papers on advanced neutron scattering instrumentation to appear in a special issue of the journal that will be published approximately in April 2018.

Neutron scattering facilities are called to address an ever-expanding mission in the investigation, development and application of a broad range of materials: from investigating cultural heritage artifacts to advanced bio-materials, from studies of phase transition and quantum matter to advanced engineering composites for aircraft. This breadth of applications, together with the complex problems they present for making scientific and technical progress, are key drivers for new advanced neutron sources and novel instrumentation that covers enormously broad scale ranges in both time and space.

This special issue on Neutron Instrumentation aims to highlight innovative advances in neutron scattering instrumentation at facilities around the world that address the broad scientific and industrial scope of applications that these facilities are called to meet. The scope of papers includes instrumentation at recent and planned facilities as well as instrument upgrades and new instrument development concepts. The emphasis of the volume will be innovative instrumentation and new scientific capabilities.

The deadline for paper submission will be 1 September 2017, with final publication of the special volume planned for April 2018 to coincide with the 50th anniversary of Journal of Applied Crystallography. This volume will be edited by Guest Editors Dimitri Argyriou (Ames Lab) and Andrew Allen (NIST), together with with several Guest Co-editors. Provisionally, these will include Ken Herwig (SNS), Kenji Nakajima (JPARC), Dan Neumann (NIST) and Masa Arai (ESS).

For enquiries on this volume, especially from potential authors regarding proposed paper content, please feel free to contact Dimitri Argyriou (argyriou@ameslab.gov) or Andrew Allen (andrew.allen@nist.gov). Completed articles should be submitted only via the special issue submission page at http://submission.iucr.org/submit/j?Qconf=ansi.
