Nature Materials has just published our paper on liquid metal-organic frameworks. Please also see comment in Nature Materials News and Views and Chemistry World; some background to our work on zeolitic imidazolate frameworks (ZIFs) is found here.

Physica Scripta have just completed a collection of papers in an online Focus Issue on Studies of Structural Disorder using Reverse Monte Carlo Methods to reflect the work presented at the The first 27 years of Reverse Monte Carlo modelling workshop in Budapest, Hungary

21 May 2015

Andrew Goodwin and I have just written a review on "The Crystallography of Correlated Disorder" in Nature.  The article reference is Nature 521 (2015) 303-309 and see Andrew's excellent web pages for a commentary on the work.

I have written an invited comment for Physica Scripta on the role of Crystallography in Physics as part of their celebrations of the International Year of Crystallography.  It is Open Access...so have a free read!

The Journal of Physics Condensed Matter has just published a Special Issue in conjunction with the RMC modelling workshop described below.  See JPCM website for more details.

The first 24 years of Reverse Monte Carlo modelling

Hotel Normafa, Budapest, Hungary

A workshop (including tutorials) to discuss the RMC method as applied to liquids, glasses and crystalline solids will take place in Hungary next year.  This meeting follows from the very well received informal meeting celebrating the first 21 years of RMC in 2009 (see news item below).  We hope that the meeting will bring together those using RMC, those interested in using RMC and those who are using related methods such as EPSR and PDFGui.  Please see the link above for further details and to express your interest in attending or email me as a member of the international advisory committee.

Approval of the XPDF Beam line on Diamond

The Diamond Board have approved the x-ray pair distribution function (XPDF) beam line to be built on I15.1.  This is great news for the UK 'PDF' community since it will provide dedicated high-quality x-ray instrumentation to complement the neutron instrumentation at ISIS.  The XPDF Working Group is chaired by Andrew Goodwin and is comprised of the following people:

Prof. Simon Billinge (Columbia University)

Dr Daniel Bowron (Rutherford Appleton Laboratory)

Prof. Andy Dent (Diamond Light Source)

Prof. Martin Dove (University of Cambridge)

Prof. Alastair Florence (University of Strathclyde)

Dr Andrew Goodwin (Chair) (University of Oxford)

Dr Joseph Hriljac (University of Birmingham)

Prof. David Keen Rutherford (Appleton Laboratory)

Prof. Gopinathan Sankar (University College London)

Details of the instrument can be found here.

Papers related to this meeting have been published in a special issue of Journal of Physics: Condensed Matter.

Large negative linear compressibility of silver(I) hexacyanocobaltate(III), Ag3[Co(CN)6]

The colossal thermal expansion described in the 8 February 2008 News item below is followed by the discovery of large negative linear compressibility (NLC) in the same material - see A L Goodwin, D A Keen and M G Tucker, Proc. Nat. Acad. Sci. (USA) 105 18708-13 (2008).  Surprisingly NLC is still retained in this material at pressures above a structural phase transition which is accompanied by a large increase in density.

Colossal thermal expansion in silver(I) hexacyanocobaltate(III), Ag3[Co(CN)6]

We have discovered positive and negative thermal expansion (PTE and NTE) in Ag3[Co(CN)6] which is more than ten times larger than the positive thermal expansion typically found in other materials.  This work has been published in Science (A L Goodwin et al, Science 319 (2008) 794, doi: 10.1126/science.1151442) and has been reviewed by Physics World and Chemistry World.  See the following links for more details:
