Heterogeneous Photochemistry of Organic-Coated Mineral Dust Aerosol

Lead Institution
University of Iowa
Principal Investigator
Vicki Grassian
Project type
Large-Scale EMSL Research
The proposed research will apply state-of-the-art mass spectrometric approaches developed for large complex molecules to interrogate chemical composition of Humic Like Substanses. Specifically, we…

Kinetic Study of Heterogeneous Reaction of Soot with Reactive Oxidants

Lead Institution
Stanford University
Principal Investigator
Hai Wang
Project type
Large-Scale EMSL Research
Heterogeneous reactions occurring between aerosol particles and reactive gaseous species in the atmosphere have significant impacts on atmospheric composition and chemistry, global radiative forcing,…

Ab Initio Studies on Voltage Gating of Ion Channels

Lead Institution
City College of New York
Principal Investigator
Michael Green
Project type
Large-Scale EMSL Research
Abstract: The ab initio and DFT computations proposed here will clarify the mechanism of ion channel voltage gating. Ion channels are proteins in cell membranes that allow passage of K+, Na+, or Ca2+…

Glycolipid Structure, Dynamics and Recognition in a Membrane Environment

Lead Institution
University of Georgia
Principal Investigator
Robert Woods
Project type
Large-Scale EMSL Research
Eukaryotic cells depend on external surface markers, such as glycolipid molecules, to recognize and bind various other molecules as part of normal growth and maturation. As glycolipid molecules are…

Use of EMSL Scanning Microscopy Capabilities to Study Soil Mineral Weathering

Lead Institution
Washington State University
Principal Investigator
J. Dickinson
Project type
Exploratory Research
Our research concerns the effect of rooted plants on chemical weathering of minerals, focusing on the associated export or loss of base cations in drainage and runoff (chemical denudation). Our work…

Adhesion of Polymer Spheres to Modified Natural Fibers

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
James Holbery
Project type
Large-Scale EMSL Research
The technical motivation of the research is to advance current capabilities in natural fiber surface chemistry to develop modification processes that simultaneously displace water within the fiber…

Reduction of U6+ by magnetite and the rate of electron transfer

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Frances Skomurski
Project type
Large-Scale EMSL Research
The reductive adsorption of uranium(VI) by ferrous iron in magnetite (Fe3O4) is an important process for reducing the mobility of contaminants in groundwater and for sequestering radionuclides in the…

Hydronium Hydroxide at Platinum Interfaces

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
James Cowin
Project type
Large-Scale EMSL Research
Hydronium hydroxide is in principle a very high-energy form of water. Normally it is considered too unstable to exist. Recent work at PNNL finds a particularly stable form of water adsorbed on a…

High-Resolution 27Al and 133Cs NMR of Weathered Hanford Sediments

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Karl Mueller
Project type
Large-Scale EMSL Research
Hanford vadose zone sediments (Hanford coarse, Hanford fine, and Ringold silt) have been weathered by reaction with a simulated Hanford tank waste leachate and examined with a wide array of…
