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.

We are sorry to announce the death of Howard Flack on 2 February 2017. Howard was known to crystallographers worldwide for many achievements in structure determination, symmetry and crystallographic software, and his scientific contributions will be described in a full obituary that is in preparation. However, perhaps less well known is his role as a pioneer in electronic publishing and the information age for crystallography, and his friends and colleagues from the IUCr Editorial office wish to remember those here.

Among Howard's consummate qualities as a scientist was a deep understanding of the importance of clarity and precision, both in the analysis of data and in the communicating of scientific results. This was always apparent in his scientific papers, or contributions to reference works such as International Tables for Crystallography. Howard also understood profoundly the importance of networking, whether the social connections between scientists, or the linking of ideas, concepts, data sets and results, and ultimately understanding, that flow from them. And so he was fascinated very early by the Internet, as a facilitator of communication and a tool for education and analysis. He established an information platform for crystallography, as part of the experimental EU CONCISE project, and very soon after that launched one of the first scientific web servers, advertising news and activities in "Crystallography World Wide". He was also very enthusiastic  about the newly emerging Usenet groups as a means of allowing scientists to communicate with each other within their areas of expertise. As Chair of the IUCr's Committee on Electronic Publishing, Dissemination and Storage of Information from 1997 to 2009, he worked closely with the IUCr editorial office to design and implement the IUCr's web server, with a rich and logical organisational structure that continues to the present. He also took a very close interest in the possibility of publishing journals, reference works and data sets electronically, and encouraged and supported the editorial office in its early efforts in this direction. With Yves Epelboin and Lachlan Cranswick, two other visionaries of electronic publication in its fullest sense, and through close interactions with Syd Hall, Frank Allen and David Brown during the early development of the Crystallographic Information Framework (CIF), Howard was a central figure in putting the IUCr at the forefront of the digital revolution.

We shall miss him.

NMR Crystallography

me0640David Bryce and Francis Taulelle introduce a special issue of Acta Crystallographica Section C: Structural chemistry on NMR Crystallography where the contributions serve as an excellent introduction to the power and scope of NMR crystallographic methods and applications.

The term crystallography, in its broadest sense, refers to obtaining structural information on crystals and related solids. Diffraction-based methods continue to play an enormous role in this area of research. Nuclear magnetic resonance (NMR) spectroscopy has, however, from its earliest days, also provided structural information on both crystalline and amorphous samples.
