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…

Quantifying Human Liver Alcohol Dehydrogenase Isoenzymes

Lead Institution
Stevens Institute of Technology
Principal Investigator
Carol Stone
Project type
Exploratory Research
Researchers report individual variation in ethanol elimination, both within and between ethnic groups, as well as between gender groups. The human alcohol dehydrogenase isoenzymes expressed in liver…

Trace signatures in particles

Lead Institution
Environmental Molecular Sciences Laboratory
Principal Investigator
John Cliff
Project type
Exploratory Research
We wish to collect a few ToF-SIMS spectra of specimens important for forensic purposes in order to include the data in a proposal (if succesfull).

Environmental Photochemical Fate of Manufactured Carbon Nanomaterials

Lead Institution
Purdue University
Principal Investigator
Inez Hua
Project type
Exploratory Research
The overall objective of the proposed research is to investigate photochemical transformation of buckminsterfullerene (C60) and single wall carbon nanotubes (SWCNT) under conditions of environmental…

Infrared Absortion Cross Sections of Acetone and Acetic Acid

Lead Institution
National Institute of Standards and Technology
Principal Investigator
Alfons Weber
Project type
Exploratory Research
Using the Bruker high resolution Fourier transform infrared spectrometer faclity of EMSL, the infrared absorption cross sections of acetone and acetic acid vapors are to be determined as functions of…

High Surface Area Nanocrystalline SiC Material Analysis

Lead Institution
Idaho National Laboratory
Principal Investigator
Daniel Ginosar
Project type
Exploratory Research
Nanocrytalline SiC materials with high surface areas have a wide range of applications in catalysts, high temperature gas separation, semiconductors, high temperature sensors and electrodes,…

Theoretical Investigations of Chiral Self-Assembly at Solid Surfaces

Lead Institution
Northwestern University
Principal Investigator
Mark Ratner
Project type
Exploratory Research
Chiral symmetry breaking is the process by which an achiral phase is resolved into two enantiomeric domains. This refers to the separation of a racemic mixture, and also to induced chiral separations…
