Urban Resilience across the Terrestrial-Aquatic Continuum

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Andrew Townsend

Despite the expansion of urban populations, the impacts of urbanization on ecosystem functions remain poorly represented in molecular-to-Earth-System-scale models. In particular, the population-dense…

Expanding metabolomics sample preparation with new desalting protocols for enhanced molecular coverage

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

William Kew

Metabolomics workflows are a cornerstone of EMSL’s user program. Routinely, samples are received which are rich in inorganic components such as salts, trace metals, and minerals. These ‘salts’ impede…

Chromatographic Approaches for Functional Natural Organic Matter Characterization

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Kent Bloodsworth

Electrospray ionization (ESI), coupled to high resolution Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS), is the de facto standard for complex natural mixture analysis. Our…

Extractions of Soil Organic Matter Using High Temperature and Pressure by Way of Commercial Espresso Machine

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Jason Toyoda

Soil contains one of the largest carbon pools on earth in the form of organic matter, which is a highly complex mixture. Characterization of organic matter can inform biogeochemical processes…

1000 Soils Research Campaign

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Nancy Hess

Project type

To more fully understand the cycling of carbon, carbon-based nutrients and key elements from the molecular to basin scale across variations in soil chemistry, the Environmental Molecular Sciences…

Nanoparticle-Cell Interactions and Intracellular Fate; Roles of Particle Surface Properties

Lead Institution

Oregon State University

Principal Investigator

Bettye Maddux

Project type

Large-Scale EMSL Research

The growing commerce in micro- and nanotechnology is expected to increase human exposure to submicrometer and nanoscale particles, including certain forms of gold and amorphous silica. Adverse…

Cellular Interactions and Fate of Engineered Nanomaterials in Alveolar Epithelial Cells at the Air-Liquid Interface

Lead Institution

Oregon State University

Principal Investigator

Bettye Maddux

Project type

Large-Scale EMSL Research

The growing commerce in micro- and nanotechnology is expected to increase human exposure to submicrometer and nanoscale particles. Adverse effects of these particles on living systems have been…

Identifying and Quantifying Sources of Variability in FTICR

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Allison Thompson

Many EMSL users are requesting Fourier transform ion cyclotron resonance (FTICR) soil organic matter (SOM) data. However, there are many circumstances where results are unexpected and experts…
