HEP Science Network Requirements

Description: The Energy Sciences Network (ESnet) is the primary provider of network connectivity for the US Department of Energy Office of Science, the single largest supporter of basic research in the physical sciences in the United States. In support of the Office of Science programs, ESnet regularly updates and refreshes its understanding of the networking requirements of the instruments, facilities, scientists, and science programs that it serves. This focus has helped ESnet to be a highly successful en… more

Reductive mobilization of oxide-bound metals

Description: We have completed a large number of experiments which examine the release of MnO{sub 2}-bound Co, Ni, and Cu. Our work has focused upon the following areas: (1) competitive adsorption among the three toxic metals and Mn(II); (2) toxic metal release upon addition of low MW organic reductants and complexants; and (3) toxic metal release upon addition of natural organic matter-rich surface waters and IHSS organic matter reference material.

Reductive mobilization of oxide-bound metals

Description: This project is concerned with the mobilization of MnO{sub 2}- and FeOOH-bound toxic metals in subsurface environments arising from an influx of natural organic matter or organic-containing wastes. Our work to date emphasizes the importance of characterizing the reductant, complexant, and adsorptive characteristics of constituent organic chemicals. Organic chemicals may interact with pollutant metals directly, or may bring about changes in speciation and solubility indirectly by acting upon MnO… more

Reductive mobilization of oxide-bound metals: The role of reductant capacity and reductant reactivity in determining mobilization rates in soils and sediments

Description: We seek to identify environmental factors that exert a decisive influence on the mobilization of oxide-bound toxic metals in soils, sediments, and aquifers. Our objective is to examine how the complexant and reductant characteristics of organic compounds found in contaminated aquatic environments influence this mobilization process. Laboratory experiments begin by allowing toxic metals (Co, Ni, Pb, Cu) to adsorb onto host oxide phases (particulate MnO{sub 2} and FeOOH) for a period of 17 hours.… more
