Transformation of 2-line ferrihydrite to 6-line ferrihydrite under oxic and anoxic conditions
Abstract Mineralogical transformations of 2-line ferrihydrite were studied under oxic and Fe3+-reducing conditions to establish the role, if any, of 6-line ferrihydrite (“well” organizedExpand
Toxicity of Al to Desulfovibrio desulfuricans
TLDR
Calculations of soluble-Al speciation for the pH 6.5 and 7.2 treatments that showed Al toxicity suggested the possible presence of the Al13O4(OH)24(H2O)127+ “tridecamer” cation and an inverse correlation of the trideCamer concentration and the cell population density, suggesting that one or both of these ions bear primary responsibility for the toxicity observed.

Enhancement of Soil Carbon Sequestration by Amendment with Fly Ash
Degraded lands (e.g., mine sites, highway rights of way, eroded lands) typically are depleted of organic-C. Progress in the reclamation of these lands can be measured, in part, by the return of soilExpand
Enhancement of Soil Carbon Sequestration: A Catalytic Approach
Introduction One of the approaches to minimizing the possible effects of climate change stemming from the recent and significant increases in atmospheric CO2 levels involves fixing or storing C asExpand
Proof-of-Concept Randomized Trial of the Monoclonal Antibody GSK249320 Versus Placebo in Stroke Patients
TLDR
GSK249320, within 72 hours of stroke, demonstrated no improvement on gait velocity compared with placebo, findings potentially useful to future studies aiming to use a monoclonal antibody to modify activity in specific biological pathways to improve recovery from stroke. Expand
Abiotic Degradation Rates for Carbon Tetrachloride and Chloroform: Progress in FY 2008
This report documents the progress made through FY 2009 on a project initiated in FY 2006 to help address uncertainties related to the rates of hydrolysis in groundwater for carbon tetrachloride (CT)Expand
Carbon Tetrachloride and Chloroform Attenuation Parameter Studies: Heterogeneous Hydrolytic Reactions -- Status Report
This report documents a project initiated in FY 2006 to help address uncertainties related to the rates of hydrolysis in groundwater for carbon tetrachloride (CT) and chloroform (CF). The studyExpand
Nanobiotechnology for enzymatic remediation and soil carbon sequestration
We studied the ability of tyrosinase to catalyze the oxidation of various phenolic compounds. As a revolutionary approach to enzyme stabilization, we developed specially-designed nanoporous silicaExpand
Fly Ash Amendments Catalyze Soil Carbon Sequestration
We tested the effects of four alkaline fly ashes {Class C (sub-bituminous), Class F (bituminous), Class F [bituminous with flue-gas desulfurization (FGD) products], and Class F (lignitic)} on aExpand
Abiotic degradation rates for carbon tetrachloride and chloroform: Final report.
This report documents the objectives, technical approach, and progress made through FY 2012 on a project initiated in FY 2006 to help address uncertainties related to the rates of hydrolysis inExpand
