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…

Xray analysis of quuantum well films

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Pete Martin
Project type
Exploratory Research
Perform x-ray analysis of superlattice and quantum well films to determine if the films have short range order. The films are deposited on Kapton substrates by magnetron sputtering.

Transition Metal Oxide Clusters - Electronic Structure and Chemical Bonding Using Photoelectron Spectroscopy (Wang's BES/Chemical Physics-Catalysis WBS0505 of Peden's BES-Chemical Transformations at Complex Interfaces, PNNL Scope #47319)

Lead Institution
Brown University
Principal Investigator
Lai-Sheng Wang
Project type
Exploratory Research
This research is aimed at obtaining a microscopic understanding of defect structures on oxide surfaces and catalytic reaction mechanisms using cluster models. Gas phase clusters provide molecular…

Characterization of Bacteriophage T4 Early Gene Proteins

Lead Institution
The Evergreen State College
Principal Investigator
James Neitzel
Project type
Exploratory Research
We have cloned and are purifying a number of early genes from bacteriophage T4. These gene products are usually lethal to E. coli, and in comparison with sequence data bases they have no obvious…
