FOREWORD The 2007 Catalysis and Chemical Transformations Program Meeting is sponsored by the Division of Chemical Sciences, Geosciences and Biosciences, Office of Basic Energy Sciences (OBES), U.S. Department of Energy. It is being held on May 23-26, 2007, at the Wintergreen Resort, Wintergreen, VA. The main purpose of the meeting is to discuss the advances made by the program PIs over the past two years, to discuss the future directions for the program and catalysis, and to foster exchange of ideas and cooperation among participants. This year’s meeting will encompass projects in heterogeneous catalysis, surface science and electrochemistry, and some of the projects recently started in nanoscience, biocatalysis, hydrogen fuel initiative, and chemical imaging. Catalysis activities within OBES emphasize fundamental research aimed at understanding and controlling the chemical reactivity of fluid and condensed matter. The long- term goal of this research is to discover the fundamental principles and develop the techniques to predict structure-reactivity relations. Such knowledge, integrated with advances in synthesis, instrumentation, characterization, and theory, will help us to control chemical reactions along desired pathways. Ultimately, this new knowledge will result in chemical and materials processes to efficiently convert fossil and renewable resources, or to generate, convert and store energy, with minimum impact to our environment. Special thanks go to our invited speakers, who will relate to us recent advances in their fields, to the program investigators and their students, postdocs, and collaborators, for their dedication to the continuous success and visibility of the OBES Catalysis and Chemical Transformations Program, and to the session moderators, for their invaluable help. We also thank the Oak Ridge Institute of Science and Education staff, Ms. Sophia Kitts, Ms. Deborah Garland, Ms. Camella Mitchell, Ms. Deborah Grubb, and Ms. Angie Lester, for the logistical and web support and the compilation of this volume.
