Journal ArticleDOI
Physico-Chemical Heterogeneity of Organic-Rich Sediments in the Rifle Aquifer, CO: Impact on Uranium Biogeochemistry.
Noémie Janot,Juan S. Lezama Pacheco,Juan S. Lezama Pacheco,Don Q. Pham,Tim M. O'Brien,Debra M. Hausladen,Vincent Noel,Florent Lallier,Kate Maher,Scott Fendorf,Kenneth H. Williams,Philip E. Long,John R. Bargar +12 more
TL;DR: It is shown that oxidative U(VI) release to the aquifer has the potential to sustain a groundwater contaminant plume for centuries and is regionally important to uranium persistence.
Journal ArticleDOI
Morphology and mixing of black carbon particles collected in central California during the CARES field study
Ryan C. Moffet,Rachel E. O’Brien,Rachel E. O’Brien,Rachel E. O’Brien,Peter A. Alpert,Peter A. Alpert,Stephen T. Kelly,Stephen T. Kelly,Don Q. Pham,Mary K. Gilles,Daniel A. Knopf,Alexander Laskin +11 more
TL;DR: In this paper, the authors examined an extensive microscopic data set collected in the California Central Valley during the CARES 2010 field campaign and characterized the particle mixing state and morphology using scanning transmission X-ray microscopy (STXM) at the carbon K-edge.
Journal ArticleDOI
Elemental Mixing State of Aerosol Particles Collected in Central Amazonia during GoAmazon2014/15

TL;DR: In this paper, two complementary techniques, Scanning Transmission X-ray Microscopy/Near Edge Fine Structure spectroscopy (STXM/NEXAFS), have been quantitatively combined to characterize individual atmospheric particles.
Journal ArticleDOI
Biological Impacts on Carbon Speciation and Morphology of Sea Spray Aerosol

TL;DR: In this article, an isolated wave channel facility was used to generate sea spray aerosol during a 1 month mesocosm study, and two consecutive phytoplankton blooms occurred, and samples were sampled throughout.
Journal ArticleDOI
Quantitative capabilities of STXM to measure spatially resolved organic volume fractions of mixed organic ∕ inorganic particles
TL;DR: In this article, the authors used carbon K-edge X-ray microscopy coupled with near-edge spectroscopy to characterize the morphology and composition of aerosol particles using NEXAFS spectrograms.
