Workshop 8

"Interfacial Chemistry in Environmental Sciences"

Date: Wednesday, May 21, 2008

Organizer(s):
Jeffrey P. Fitts (ESD-BNL) fitts@bnl.gov
Paul Northrup (ESD-BNL) northrup@bnl.gov

Location:  Berkner Hall, Building 488, Conference Room B

Description:
Reactions at mineral-water interfaces are integral to a diverse array of environmental processes including element cycling in the oceans, contaminant transport in groundwater, and aerosol formation in the atmosphere. Atomic-level details of these processes have only recently begun to emerge as a result of the development and application of synchrotron-based methods adapted to the study of mineral-water interfaces. This workshop will provide an overview of a variety of techniques used today to study the structure of hydrated mineral surfaces, adsorbate ions and water composition profiles at environmental interfaces. In addition, the workshop will look at how these applications along with current efforts at the NSLS and CFN will benefit from the unique characteristics of NSLS II.

The workshop will be of direct interest to: Earth and environmental synchrotron users; NSLS and CFN users and researchers who study phenomena at liquid-condensed matter and liquid-soft matter interfaces.
