Volatile organic compounds (VOCs, released from plants, soil and leaf litter) are important precursors of ozone and secondary organic aerosols. Gaps in observations of vertically-resolved, chemically…

Algae from Ocean to Atmosphere: Exploring Coastal Ecosystems and Their Impact on Health, Climate, And Precipitation

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Michaela Rogers

Marine species undergo biogeochemical cycles which yield highly dynamic composition at the ocean interface and air environment. With uncertainty in ocean and atmosphere composition, experimental…

Development of nanospray desorption electrospray ionization with sample imprinting as a tool to characterize microbial and below-ground interfaces

Lead Institution

Principal Investigator

Elizabeth Shank

Project type

Exploratory Research

Bacteria live everywhere, from the soil and sea to the surface of every plant and animal on earth. Most bacteria exist within diverse, multispecies communities that exert profound impacts on their…

Development of a nano-desorption atmospheric pressure photoionization (nano-DAPPI) advanced mass spectrometry platform

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Swarup China

Natural organic matter from atmospheric aerosol and soil consist of complex molecules with range of polar and non-polar compounds. Previously EMSL developed a unique platform, nano-desorption…

Characterizing role of particle-water in processing of biomass burning emissions and SOA formation

Large-Scale EMSL Research

Secondary organic aerosol (SOA) formed by multiphase chemical reactions in the atmosphere greatly contribute to fine particulate matter and organic aerosols (OA). Despite mounting evidence, aqueous-…

Tracing rhizosphere carbon exchange processes and nutrient interactions

Lead Institution

Michigan State University

Principal Investigator

James Moran

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…

Development and implementation of an in situ high-resolution isotopic microscope for measuring metabolic interactions in soil microcosms

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Christopher Anderton

Soil microbial processes exert a major influence on many of our planet's ecosystems, yet our ability to directly observe the enzymatic and metabolic activities of microbes within soil is…

TWIN Ecosystems Project

Lead Institution

Principal Investigator

Nancy Hess

The goal of the TWIN ecosystem project (‘TWINS’) is to pilot laboratory and field ‘twin’ ecosystems that use sensors and autonomous controls to test the hypothesis that compositional changes in root…

The secret life of plants: intact protein mass spectrometry imaging by nanospray desorption electrospray ionization (nanoDESI)

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Kevin Zemaitis

Intact protein mass spectrometry imaging (MSI) is a niche field of study which combines the specificity of mass spectrometry (MS) with the capabilities of visualization as in microscopy. Proteomics…

Development and evaluation of low-temperature plasma (LTP) for organic matter and aerosol analyses by FTICR mass spectrometry

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Kevin Zemaitis

The analyses of various forms of organic matter (OM) and secondary organic aerosols (SOA) by high-resolution mass spectrometry (e.g., FTICR MS) has found great utility in broadly characterizing…
