Rhizodeposition represents the largest flux of photosynthetically derived organic matter into soil for most terrestrial systems and, in so doing, serves as a major point of connection between…

High Confidence Characterization of Organohalogen & Organometallic Compounds by Orthogonal LC-ICP and LC-HR Mass Spectrometry

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Yuri Eberlim de Corilo

Interactions between metals, halogens, and other elements are critical regulators of organic matter transport, persistence, and toxicity. Still, they remain poorly characterized due to the samples&…

Development of high-throughput metabolomics technologies: Application to studying the flowering time in Arabidopsis thaliana

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

David Hoyt

The future trajectory of metabolomics and its applications largely depends on the analytical capabilities of NMR and MS and their combination. Although the use of both NMR and MS methods is…

Statistical Methodology for Characterization of Macromolecular Similarity

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

John Cort

As with any drug, approval of generic versions of macromolecular drugs requires rigorous evaluation of therapeutic equivalence to the reference drug in order to assure similar efficacy and safety…

Elucidating synergistic plant-bacteria metabolic pathways for alleviating iron deficiency

Lead Institution

Oregon State University

Principal Investigator

Rene Boiteau

Nutrient mobilization from soil minerals is critical for plant growth, particularly in marginal lands with high pH soils or low phosphate availability. One way that rhizospheric bacteria enhance…

Structure and Chemical Mapping of Soil Organic Matter on Mineral Surfaces

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Ravi Kukkadapu

Secreted and decomposing soil organic matter (SOM) containing carbon, nitrogen, phosphorus, and metals form the basis of many bio/organic matter-mineral interactions in soils. These compounds are …

Interactive mechanisms of mineral dissolution by a microbial consortia

Lead Institution

Hebrew University of Jerusalem

Principal Investigator

Yeala Shaked

Project type

FICUS Research

Essential metabolic functions within ecosystems are often partitioned among various members of microbial communities that each benefit the whole population. For example, nitrogen fixation is carried…

Reactivity of Soil Organic Carbon with Minerals under Low Water Conditions

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

John Loring

Project type

Exploratory Research

The manner in which soil organic carbon (SOC) binds to and reacts with mineral surfaces affects SOC (bio)degradation, SOC mobility, soil wettability, mineral dissolution, and the bioavailability of…

Position-specific stable isotope analysis for elucidating provenance and fate of organic matter

Lead Institution

Michigan State University

Principal Investigator

James Moran

The EMSL 21T FTICR MS is amongst the highest mass resolution of any mass spec ever developed (> 6M at m/z 700 (Shaw et al., 2016)). We seek to provide a proof of concept that suitable stability…
