A., 173 Zecchina, A., 609Special Issues of Faraday Transactions Readers of the Faraday Transactions will be aware that we have now established Special Issues which fall broadly into two categories: Collections of the refereed papers that have been presented at a Scientific Conference, normally run by a Subject Group of the RSC, and approved in advance by the Fur- Editorial Board.We insist, with varying degrees of success, that the papers published under this scheme shall describe original work which fully meets the n o d requirements for submittedpapers. Keynote Issues which are opened by a paper written by an acknowledged authority in a particular field of interest. The Keynote author then invites colleagues known to him to contribute original papers on cognate topics, to appear in the same Keynote Issue. These papers are refereed and, as intended, have led to issues of an exceptionally high scientific standard. The initial stage of this development having been completed, Farakzy Editorial Board has directed that wider invitations should be issued to the physicochemical and chemical physics community to send us origrnal work which they would like to appear alongside papers on similar topics. Special issues in the planning stage include the topics listed below.If you think that you have some good work coming along which could be ready for submission around the indicated date, please do write to me and let me know, when I will make the necessary arrangements. For my part, I see no objection to adding such papers to Special Issues in both categories.

The systems include conducting polymers, redox polymers, ion exchange membranes and modified electrodes. Discussion topics will cover experimental evidence from spectroscopy, electrochemistry and new techniques such as the quartz microbalance. Theoretical models ranging from band theory through polarons to localised chemical structures will be critically evaluated and compared with experiment. The following have agreed to participate in the Discussion: R.Murray W. J. Albery M. D. lngram M. 6. Armand D. Bloor H. Cheradame P. G. Bruce R. Friend R. J. Latham A. J. Heeger A. R. Hillman P. V.

Al.Weiss (F.R.G.) M. Zeidler (F.R.G.) G. R. Luckhurst (U.K.) The purpose of the meeting is to bring together scientists working on transport and related phenomena in simple and complex fluids, colloidal and micellar systems, and surface phases. Experimental techniques considered include classical methods, optical spectroscopy, light scattering, nuclear magnetic resonance, and neutron scattering. The following persons have accepted invitations to present talks: D. Evans, Canberra; B. U. Felderhof, Aachen; D. Frenkel, Amsterdam; A. Geiger, Dortmund; W. Gliiser, Grenoble; H. G.

Jennings (Chairman) Professor P. J. Derrick Professor D. Phillips Dr N. Quirk Dr R. P. H. Rettschnick Dr A. J. Stace The Symposium will focus on recent developments in the rapidly expanding field of large gas phase clusters, including the preparation, structure and reaction of both neutral and ionic clusters.It is hoped that the meeting will bring together scientists working on many different types of cluster, e.g. rare gas atoms, metals, inorganic and organic species, and biomolecules, to discuss the chemistry and physics of clusters from different viewpoints.

THE FARADAY DIVISION OF THE ROYAL SOCIETY OF CHEMISTRY GENERAL DISCUSSION No. 89 Structure of Surfaces and Interfaces as Studied using Synchrotron Radiation University of Manchester, 4-6 April 1990 Organising Committee: Professor J. N. Sherwood (Chairman) Professor D. A. King Dr G. King Dr C. Norris Dr R. Oldman Dr G.Thomton The Discussion will focus on the wealth of novel information which can be obtained on the nature and structure of surfaces using the full spectral range of synchroton radiation. Emphasis will be placed on the scientific results of recent investigations rather than on technical aspects of experimentation. Papers will be welcome which shed new light on the structure of the complete range of interfaces: solid/solid, solidlgas, solifliquid, gasniquid and "dean" surfaces including both static and dynamic in situ examinations. It is hoped that the discussion will define the utility of synchroton radiation examinations in surface science studies at a time of expansion of the availability of such sources and the inauguration of new and more powerful sources.
