Dr. Claude R. Henry is director of Interdisciplinary Nanoscience Centre of Marseille. He obtained his Ph.D degree in 1983 in Marseille. and got Post Doctoral position at IBM ARC (San José, California) and Stanford University (1986-87).He is an Invited Professor at Ecole Polytechnique Fédérale at Lausanne (Switzerland) and the Fritz Haber Institute (Berlin).He is a member of the Steering Committee of the European Network ‘Gas-Surface Dynamics',the Advisory Board of 10 CNRS laboratories in France and the steering committee of the Condensed Matter Division of the French Physical Society. He is an Editorial Member of Surface Science and of the Journal of Physics: Condensed Matter Member of the committee of more than 100 PhD Theses Defenses. He has authored more than 260 publications, and his research work has obtained more than 9700 citations with H index of 49. His research interest includes the morphology, nucleation and growth of supported clusters on nominal and nanostructured oxides surfaces. He is an expert at the OMNT (French observatory of micro and nano-technologies) Chairman of 3 International Conferences.

Abstract:

Study of the morphology of supported nanoparticles in situ during a catalytic reaction at realistic pressures by environmental HRTEM. Micro-Kinetic simulation of catalytic reactions at surfaces. KMC simulation and kinetic modelling of heterogeneous nucleation and growth of clusters. Nucleation and Growth of metal clusters on nominal and nanostructured oxides surfaces studied in situ by diffraction of He atoms (TEAS), Surface X-rays scattering (GISAXS), Auger Electron Spectroscopy, STM, AFM and ex situ by TEM. Study of the structure and morpholopgy of supported clusters by scanning probe microscopies (STM and AFM) and HRTEM. Electronic structure of metal clusters studied by Electron Energy Loss Spectroscopy. Adsorption and bimolecular reaction kinetics on supported clusters and thin films studied by Infrared Spectroscopy and Molecular Beam Relaxation Spectroscopy.
