Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Jian-zhi Hu
We propose to use NMR in combination with computational modeling, to study the conversion of soluble tetrahedral aluminum (Al) species to octahedrally coordinated Al-bearing mineral precipitates under strongly basic conditions typical of high-level...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: James De Yoreo
The aims of the proposed research are to: 1) Determine the structure of the near surface water layer in the confined region between approaching mineral surfaces and determine the impact of electrolytes and bioorganic ligands on that structure, and 2...
Lead Institution: University of Florida
Principal Investigator: Hui-ling Liao
As the critical members of forest microbiome, ectomycorrhizal fungi (EMF) play important roles in forest ecosystems. EMF provide their tree hosts with macro- and micronutrients in exchange for photosynthetically fixed carbon (C) and can catalyze the...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Kevin Rosso
Understanding aquatic chemistry, the natural cycling and fractionation of elements, and energy flow in soils almost always involves, by necessity, attention to the governing influence of electron transfer processes. Interaction of aqueous Fe(II)...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: James De Yoreo
The aims of the proposed research are to: 1) determine the impact of adsorbed organics on mineral-solution interfacial structure, 2) understand how organics impact solution speciation during mineral nucleation, and 3) determine the mechanisms by...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Kevin Rosso
Fe(III)-oxide nanominerals are ubiquitous primary sorbents of organic carbon, organic acid exudates, and toxic metals in terrestrial, aquatic, and subsurface ecosystems. In soil ecosystems, particularly in the rhizosphere, this co-association has...
Lead Institution: Oregon State University
Principal Investigator: Kelsey Stoerzinger
Iron (Fe)-containing minerals exert a significant influence on soil and sediment geochemistry, such as the cycling of nitrogen (N) and phosphorus (P) nutrients in the bioavailable form of dissolved oxyanions. Initial efforts have been made to...
