EnviroSync: Facilitating Environmental Science with Synchrotron Radiation

EnviroSync serves as an advocate for the MES-SR community, assesses existing SR facilities for research, and advises on new SR facilities. Engage in workshops and meetings to evaluate synchrotron radiation capabilities and future needs for molecular environmental science and low-temperature geochemistry. Techniques commonly used include STXM, X-ray scattering, XAS, X-ray microprobe, and IR microscopy. Projects span environmental science, geochemistry, biology, medical science, astrobiology, and more. Contact John Bargar at SSRL or Peter Nico at ALS for further details.

Presentation Transcript

  1. The main purposes of EnviroSync are to: (1) serve as an advocate for the MES-SR community (2) assess the state of existing SR facilities for MES research on a continuing basis (3) assess the SR needs of the MES community on a continuing basis (4) serve as an advisory group to federal agencies concerning the need for new SR facilities in the MES area

  2. EnviroSync Workshops and Meetings • Assessing Synchrotron Radiation Capabilities and Future Needs for • Molecular Environmental Science and Low-Temperature Geochemistry • 23-24 July 2007, Rockville, MD • Synchrotron Environmental Science Workshop Series • SES III September 2005 NSLS • SES IV Fall 2008 SSRL (Stanford) • Contact: John Bargar at SSRL or Peter Nico at ALS • Periodic informal meetings at national meetings (e.g., ACS)
