Other "photonic"-related effects are also under consideration. Studies on selforganization of defects upon laser irradiation (L.D. Laude, M. Wautelet) should also be mentioned.
Surfaces The surface properties of thin films and monocrystals are studied in a lf>" torr vacuum chamber, by means of LEED, Auger, and UPS. The chamber is coupled to an excimer laser, allowing the study of lasersurface interaction mechanisms (L.D. Laude, M. Wautelet). Theoretical research on catalytic surface This article is part of a series focusing on the research capabilities and goals of reactions (laser assisted or not) is devoted interdisciplinary laboratories pursuing materials research in universities, industry,to stability analysis and model testing. For that purpose, Monte Carlo simulations of and government. surface reactions have been conducted (R. Dagonnier, M. Dumont).

The State University of Mons was established in 1965, at the heart of an old industrial region of South Belgium. Since that time, the role of the University emerged as a source of new ideas for the region. The Department of Materials was founded in 1988, developing from the identification of various groups and their expertise in the materials science field. The goal of the Department of Materials is "to arrange and promote researches in this field. The Department will also work at improving education in Materials Science." The Department will continue existing contacts and promote new contacts with regional, national, and international industries, and its experimental facilities are accessible to all interested researchers. The members of the Department of Materials belong to the Faculties of Science and Medicine of the State University of Mons. They form an interdisciplinary group, including physicists, chemists and biologists—experimentalists and theoreticians. Although some research activities involve more than one group, they can be arranged according to either the nature of materials (thin films, polymers, surfaces, quasi-one-dimensional conductors, biomaterials) or methods of preparation (laser irradiation, chemical vapor deposition, electron evaporation) and characterization (electron and x-ray diffraction, spectrophotometry, FTIR, micro-Raman, electrical conductivity, surface analytical techniques).
Thin Films Thin films are deposited either by sputtering deposition, electron evaporation, or Joule effect. Films prepared by sputtering deposition are characterized by an original method developed in Mons. Soft x-rays

emitted by the sample during bombardment by electrons from the plasma are analyzed by a spectrometer. This allows characterization of materials during deposition. Films are also studied by more classical x-ray and electron microscopies. Afterwards, their physicochemical properties (electrical and catalytic properties) are analyzed. Under controlled electron bombardment, monocrystalline epitaxial Pt films have been obtained, with catalytic properties similar to the case of monocrystals (J.P. Dauchot, M. He
