The role of Fe(oxyhydr)oxides in regulating the biogeochemical cycling of Zinc; an essential micro-nutrient

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Eugene Ilton

Project type

Large-Scale EMSL Research

We propose to study the influence of Fe(III) (oxyhydr)oxides on the biogeochemical cycling of Zn, an essential micronutrient. The work is specifically focused on incorporation of Zn into the…

EMSL resources are requested to enable an international team of collaborators to solve fundamental problems in interfacial glass corrosion chemistry. With the recent dismissal of Yucca Mountain as…

Mineral Reactivity and Transformations in Adsorbed Water Films

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

John Loring

Project type

Large-Scale EMSL Research

Transformations of minerals covered in thin films of adsorbed H2O are ubiquitous in nature and occur under unique chemical and physical constraints. But in contrast to bulk aqueous systems,…

Influence of Adsorbed Organic Acids on Soil Mineral Wettability

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

John Loring

Project type

Large-Scale EMSL Research

Soil wettability is dictated by the extent to which hydrophilic mineral surfaces are covered by hydrophobic soil organic carbon (SOC) from bacterial decomposition, decaying plant matter, or root…
