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: 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: University of Puget Sound
Principal Investigator: Amanda Mifflin
The proposed work will examine the interfacial phenomena of the organic ligand acetohydroxamic acid (aHa) at the hematite/water interface and the molecular structure at organic/aqueous interface using the nonlinear optical spectroscopy techniques...
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...
