Our program has a single overarching goal: to synthesize and to understand the basic principles governing properties and behavior of novel materials and structures. Our program is committed to world-class research currently focusing on two classes of solid-state materials:(1) Metal-rich inorganic solid-state phases including quasicrystalline materials; and (2) Macromolecular systems. In both classes, development of heretofore-unknown materials is emphasized. A synergistic combination of experiment and theory involving multi-disciplinary approaches is a hallmark of the program. Within the first class, metal-rich solid-state phases, topics of investigation are electronic stabilization; atomic structure; surface structure and properties; solute effects; and macroscopic growth. a particular strength is our work on quasicrystalline materials, which constitute a subset of metal-rich solid-state phases. Within the second class, macromolecular systems, the emphasis is on the development of novel polymeric and polymer-inorganic bioinspired materials that exhibit self-assembly at multiple length scales. An important aspect is the development of nuclear magnetic resonance techniques for characterization of these bioinspired materials.

Chemistry and biology are typically viewed as discrete academic disciplines, yet the two are highly integrated. Today, scientists increasingly use chemical tools to study dynamic biological processes at the gene, cellular, and organismal level. The Broad Institute's Chemical Biology program applies this approach to biomedical research and the pursuit of new methods to ameliorate disease. Its activities aim to diminish existing and future gaps between biology and medicine.

Both science and the economy in the 21st century will require technological breakthroughs in the control of nanometer scale structure and functions, where the top-down approach of electronics manufacture converges with the bottom-up assembly of biology. At this moment, the scientific questions are being formulated, the required tools are being developed, and the possible applications of nanotechnologies and applications will be revolutionary. The University of California, Los Angeles and University of California, Santa Barbara have joined to build the California NanoSystems Institute (CNSI), which will facilitate a multidisciplinary approach to develop the information, biomedical, and manufacturing technologies that will dominate science and the economy in the 21st century.

The Brookhaven National Laboratory Center for Functional Nanomaterials will provide researchers with state-of-the-art capabilities to fabricate and study nanoscale materials. Functional materials are those which exhibit a predetermined chemical or physical response to external stimuli. The Center's focus is to achieve a basic understanding of how these materials respond when in nanoscale form. Nanomaterials--typically on the scale of billionths of a meter--offer different chemical and physical properties than bulk materials, and have the potential to form the basis of new technologies.

About 80 percent of the U.S. population live in metropolitan areas. These urban residents face a number of pressing environmental problems including exposure to toxic chemicals from contaminated sites, landfills, incinerators, abandoned industrial sites (Brownfields), industrial releases, lead, and pesticide use. The U.S. Environmental Protection Agency (EPA) established the Hazardous Substance Research Centers (HSRC) Program to develop better, more cost-effective, faster, and safer methods to assess and clean-up environments contaminated with hazardous substances. Johns Hopkins University has received an award from EPA as the lead institution for a new HSRC.

The Center for Nanotechnology at the University of Washington was created in 1997. It brings together faculty members and students from the Colleges of Arts and Sciences, Engineering, Pharmacy, and the School of Medicine. The Center enjoys major financial support from the University of Washington Initiatives Fund (UIF) and National Science Foundation Integrative Graduate Education and Research Traineeship (NSF-IGERT) program.

Within Chemical and Biological Sciences, three research divisions existEnvironmental Sciences, Fundamental Interactions and Molecular Processes. Environmental Sciences researchers study the chemical and physical aspects of chemical carcinogenesis by advanced laser techniques. They are also working to develop new approaches and to improve on existing technologies relevant to gene mapping and to DNA sequencing. The Fundamental Interactions division consists of Chemical Physics, in which research on the fundamental reactions in combustion and the nature of heterogeneous catalysis is performed, and Photochemical and Radiation Sciences, in which group members perform research on the fundamental processes in biological solar energy conversion. The Molecular Processes division consists of Chemical Energy, which is focused on catalysis, and Chemical Separations and Analysis, which is focused on analytical applications. Current projects in the Chemical Energy area include chemical kinetics and reactivity of transition metal complexes, new synthetic routes to inorganic catalytic materials using organometallic precursors and molecular "stepping stones", spectroscopic and kinetic characterization of metal oxide catalysts, spectroscopic and phenomenological studies of catalysts and advanced materials, and organometallic complexes in homogeneous catalysis. Chemical Separations and Analysis projects are in the areas of analytical separations, analytical spectroscopy, lasers in analytical chemistry, chemical analysis at liquid-solid interfaces, and metal hydride batteries.

Chemical physicists at JILA probe the structure and dynamics of ions, free radicals, cluster ions, and molecules; seek to understand the quantum mechanical behavior of chemical reactions; study the process of solvation; and investigate single entities such as quantum dots. Experimental chemical physicists use a variety of laser-based techniques to better understand hydrogen bonding, electron transfer, the formation and dissolution of chemical bonds, chemical reactions, and the formation of nanoparticles. Theoretical physicists create simulations of the molecular processes probed in these experiments to both explain results and guide future investigations. The goals of chemical physics research at JILA include understanding chemical structures and reactions at the quantum mechanical level, elucidating the structure and reactivity of gas phase ions, and discovering new approaches to explaining chemical physics.
