The workshop came off without a hitch thanks to the efforts of our local organizer, Prof. Stephen Elliot. We were even blessed with two out of three days of sunshine in the one of the wettest summers in Great Britain in a century! The conference proceedings have now been published as a special section in the Journal of Physics: Condensed Matter.

Description

Quantifying the structural order in amorphous and partially ordered solids, and the effects of such order on solid-state properties, has been a longstanding challenge in materials physics and chemistry.  Disordered materials possess strong short-range order driven atomic packing and bonding but lack the long-range order which allows for analyses based on periodicity.  Therefore, techniques to measure order on the few nanometer scale (4th or 5th coordination shell or larger) must discern the signatures of order against a large background of structural disorder, and interpret these signatures in terms of structure.  Similarly, the effects of order on solid state properties must be distinguished from the properties of the disordered background.  Despite these formidable challenges, significant progress has been made during the past few years in experimental techniques, theoretical understanding, and simulation of structure and properties.  These themes were the focus of a workshop held at the University of  Illinois in 2003, a symposium held at Microscopy and Microanalysis in 2004, and the GLAMOR workshop held at Cambridge University in 2005.

The 2007 International Workshop on Nanoscale Order in Amorphous and Partially Ordered Solids will bring together researchers in structural characterization and analysis, simulation, and theory of amorphous and partially ordered materials.  The broad goal is to provide a forum in which the participants will learn the latest developments, build intellectual bridges between neighboring areas of research, and have ample opportunity to discuss and debate future directions.  The workshop will be hosted by Professors Steve Elliott and Paul Midgley in the Trinity College at the University of Cambridge, UK.

Contributions and Travel

Contributions to the workshop in the form of posters are solicited. Posters presenters will also have give very short (5 minutes) "advertising" presentations to the group before each poster session. To make a contribution, please register, then download the abstract template (MSWord, plain text), and email your completed abstract to Paul Voyles with "nanoscale workshop abstract" in the subject line by the deadline of April 15, 2007.

Proceedings papers are invited for both poster presentations and invited talks. The Proceedings will be published in a special issue of Journal of Physics: Condensed Matter. Papers are expected to meet the usual quality standards of the journal, and must report substantial new research and should typically be approximately 10-12 pages in length in published form. Also, to increase the coherence of the volume, we would welcome short discussions in the manuscripts indicating the connectivity between different measurements, methods and materials. To the greatest possible degree,  the review process for the manuscripts will be carried out during the meeting and we will make every effort to publish the Proceedings in a timely manner. Feel free to direct questions about the Proceedings to David Drabold (drabold@ohio.edu).

Student attendees from the US are encouraged to submit an application to the Student International Conference Travel Scholarship program of the International Materials Institute for New Functionality in Glass, a program sponsored by the U.S. National Science Foundation. A small amount of additional funds are available to support travel costs for non-US students. If you would like to be considered for that support, please contact Paul Voyles.

General information on traveling to Cambridge or to Trinity College, and on the surrounding area may be found found on various Cambridge web sites.
