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. B. Armand D. Bloor P. G. Bruce R. Friend A. J. Heeger A. R. Hillman A. G. MacDiarmid M. Ratner S. Roth W.

THE FARADAY DIVISION OF THE ROYAL SOCIETY OF CHEMISTRY GENERAL DISCUSSION No. 89 Structure of Surfaces and Interfaces as Studied using Synchroton Radiation University of Manchester, 4-6 April 1990 Organising Committee: Professor J.N. Shewood (Chairman) Professor D. A. King Dr G. King Dr C. Nods Dr R. Oldman Dr G. Thornton 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, solid/gas, solidAiquid, gasniquid and "dean" surfaces including both static and dynamic in sifu 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.Contributions for consideration by the Organising Committee are invited and abstracts of about 300 words should be sent by 31 May 1989 to: Professor J. N. Sherwood, Department of Pure and Applied Chemistry, University of Strath- Clyde, Thomas Graham Building, 295 Cathedral Street, Glasgow G1 1 X L Full papers for publication in the Discussion Volume will be required by December 1989.THE FARADAY DIVISION OF THE ROYAL SOCIETY OF CHEMISTRY ASSOCIAZIONE ITALIANA DI CHIMICA FlSlCA DEUTSCHE BUNSEN-GESELLSCHAFT FUR PHYSIKALISCHE CHEMIE KONIKNLIJKE NEDERLANDS CHEMISCHE VERElNlGlNG SOCIETE FRANGAISE DE CHIMIE, DIVISION DE CHlMlE PHYSIQUE FARADAY DIVISION GENERAL DISCUSSION No.90 Colloidal Dispersions University of Bristol, 10-12 September 1990 Organising Committee Professor R.
