EBI - Call for Preproposals, Deadline 5/31/13

The 2013 call from the Energy Bioscience Institute (EBI) has been posted on EBI's website (http://www.energybiosciencesinstitute.org). The deadline for preproposals is May 31, 2013.

LBNL-UCD Predictive Agriculture Workshop

The First Partnership Workshop of the LBNL/UC-Davis Predictive Agricultural Initiative focused on how to sustainably manage agricultural systems for a growing world population under changing environmental conditions.

ESD’s Ice-Breaking Science

ESD’s Susan Hubbard and her colleagues have trekked to Alaska throughout the past year to follow changes to the permafrost, seeking to understand how climate change will influence the trajectory of the permafrost system.

A Wealth of Earth Day-Week Activities

LBNL Deputy Director Horst Simon, in a message to the Lab, announces a wealth of Lab activities related to Earth Day and Earth Week, and invites all Lab employees to learn how they can make a positive impact.

Chakraborty Article a Big Hit!

ESD’s Romy Chakraborty recently found out that her article “Microbial response to the MC-252 oil and Corexit 9500 in the Gulf of Mexico” was among the most “viewed” articles in the journal (Frontiers in Microbiology) this past year.

Controlling Effective Kinetic Cr Isotope Fractionation

Most studies related to the subject propose a variation in Cr(VI) reduction mechanisms as being responsible for the wide range of effective kinetic Cr isotope enrichment factors.

Nigel Quinn Wins Hugo B. Fischer Award

ESD Website Teaser: ESD’s Nigel Quinn was recently honored with the 2013 Hugo B. Fischer Award, in recognition of his significant contributions to real time data management, decision-support tool development, and hydrology and water quality forecasting.

Groundwater Uranium Plumes at Two DOE Sites

ESD scientists were part of a group that examined subsurface uranium (U) plumes at two U.S. Department of Energy sites (Hanford and Rifle) located near large river systems that are influenced by groundwater–river hydrologic interaction.

U Pathways in Acetate-Amended Sediments

In a recent article published by the NAS, a team of ESD investigators headed by ESD’s John Bargar present results from an in situ study of uranium redox transitions occurring in aquifer sediments under sulfate-reducing conditions.

Evaluating ion exchange resin efficiency and oxidative capacity for the separation of uranium(IV) and uranium(VI)

Previous methods for separating dissolved U(IV) from dissolved U(VI) under acidic anoxic conditions prior to laboratory analysis were ineffective with materials currently available commercially. ESD’s Jim Davis was recently part of an investigative team that examined three strong anion exchange resins for their efficiency in separating, recovering, and preserving both redox states during separation.
