Effect of NAPL Dissolution on NAPL-Water Interfacial Area

Lead Institution
Swiss Federal Institute of Technology
Principal Investigator
Martin Schroth
Project type
Exploratory Research
The release of nonaqueous-phase liquids (NAPL) into soils and aquifers is a widespread and serious environmental problem. The typically low solubilities of NAPL cause them to dissolve slowly; thus…

SEM-EDS Elemental Mapping of Weymouth Soils

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Kirk Cantrell
Project type
Exploratory Research
During operation of the former Weymouth phosphate fertilizer plant, sulfuric acid was produced to dissolve phosphate ore. The sulfuric acid was produced from Fe sulfide ore which was composed…

Segregation on Annealed R-Cut Sapphire Surfaces

Lead Institution
University of Maine
Principal Investigator
Steven Rivers
Project type
Exploratory Research
We are currently studying step/terrace formations on r-cut sapphire surfaces with miscuts less than 0.5°. These sapphire wafers are used as thin-film substrates in our lab. Through atomic force…

Nanoengineered Electrochemical Sensor for Mixed Wastes (PNNL Scope# 45409)

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Jun Wang
Project type
Exploratory Research
The purpose of this proposal is to develop portable electronic and optical chemical and biosensor devices integrated with novel nanoparticle materials for fast, low-cost, specific and sensitive…

Structure of the Shewanella cell surface

Lead Institution
University of Georgia
Principal Investigator
Andrew Neal
Project type
Exploratory Research
The bacterial cell surface is a complex, dynamic interface acorss which the cell interacts with its environment. From the perspective of iron reducing bacteria such as Shewanella, the cell surface…

Mechanisms of organic ions release from water droplets.

Lead Institution
University of Colorado at Boulder
Principal Investigator
Gayfree Ellison
Project type
Exploratory Research
Second Generation of Single Particle Laser Abletion Time-of-Flight Mass Spectrometer will be used to investigate the mechanisms by which organic ions are released from water droplets.

Growth of Thin Film Model Oxide Catalysts

Lead Institution
Yale University
Principal Investigator
Eric Altman
Project type
Exploratory Research
Although oxides are widely used to catalyze partial oxidation reactions and the selective reduction of NO, the relationship between catalytic activity and structure remains poorly understood. It has…

Ion Funnel Development (PNNL Scope #48165, K.Tang JPL-Ion Funnel Project)

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Keqi Tang
Project type
Exploratory Research
Design and construct an electrodynamic ion funnel and associated components suitable for interfacing with the JPL mass spectrometer and laser ablation systems. Characterize and optimize the ion…

Site Specific Valence Above and Below the Verwey Transition in Magnetite

Lead Institution
Argonne National Laboratory
Principal Investigator
Julie Cross
Project type
Exploratory Research
ABSTRACT: The Verwey transition has historically been described as an electron-ordering transition in a mixed-valent system that results in ordering of the formal valence states in the low…

Aerosol Aging and Climate Change (Cowin's NOAA, PNNL Scope #47840)

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
James Cowin
Project type
Exploratory Research
Using easily field-deployable, time-resolved aerosol collectors (TRAC and TAQ) create sample archives that permit quantitative, single particle-size and elemental-composition analysis of mixed…

Use of SEM/EDX Analysis to Study the Oxidation of Aerosol by Hydroxyl Radical

Lead Institution
University of California, Irvine
Principal Investigator
Barbara Finlayson-Pitts
Project type
Exploratory Research
Unique chemistry at the air-water interface between chloride ion in sea salt aerosol and the hydroxyl radical (OH) has been suggested to play a major role in the production of increased levels of…
