Dear Michaela, At the end of our stay we prepared three samples which perhaps could be the basis of a future project. Two are of rare earth vanadates (part of a latrger series) in our own capillaries of diameter 0.3. We used this diameter believing that the heavy rare earths would make problems due to absorption if prepared in 1 mm capillaries. Later, I realised that this diameter is not necessarily suitable because of high rotation speed - perhaps one could locate these capillaries inside larger capillaries to avoid the effect of bending during rotation? Or reduce the speed of rotation? (We had also a problem of centering the capilaries during mounting, we did it only roughly using wax it in a hurry because of the flight connection.) The third material is an organic requiring a good resolution to solve the structure, loaded into 1 mm capillary. It would be nice if the above samples were measured at some spare time at best with a statistics permitting for Rietveld calculations.
Please note that we have some conferences in Poland next year. I am involved in organisation, so if you'd like to come and had some questions, please do not hesitate to ask. I am sending essentially the same information to Irene, in order to avoid confusions.

Workshop on Total scattering Pair Distribution Function analysis using X-rays and neutrons: powder diffraction and complementary techniques ESRF, Grenoble, France, 22nd - 23rd October 2007 Traditional crystallography breaks down on the nanoscale and we need complementary technique such as PDF for nanostructured materials. Today, this is known as the "nanostructure problem". Total scattering PDF analysis from powder diffraction data cover areas of technological and material science relevance, and it is specially successful in the investigation of the atomic-scale structures of nanosized materials. The aim of the workshop is to bring together people involved in the development and implementation of the different Total Scattering data analysis strategies, for generalising the availability of these methods, via the sharing of knowledge, so that in the future this approach is routinely done together. A session on the future needs for beamlines at the ESRF will be included. The meeting will be hosted by the ESRF in Grenoble, France and will take place on the 22nd and 23d of October 2007. The number of participants is limited and application is open till 1st of October, 2007. More detailed information, the course programme and instructions as to how to apply to attend the meeting can be found in our web pages: http://www.esrf.fr/events/conferences/PDFPowderDiffraction/PDFPowderDiffractionAnnouncement Please don't hesitate to contact us if you have any questions regarding this workshop. We look forward to seeing you in Grenoble!! Michela Brunelli on behalf of the organising committee: Simon J. L.
