Optical Properties of Epitaxial Chromium Sesquioxide Films

Lead Institution
IBM Almaden Research Center
Principal Investigator
Roger Macfarlane
Project type
Exploratory Research
The aim is to measure the optical properties of epitaxial films of Cr2O3 particularly the sharp 2E excitons in the near infrared. These should act as a sensitive probe of film strains and purity as…

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…

Characterization of Gold Nanoparticles by FTICR MS/MS

Lead Institution
University of North Carolina
Principal Investigator
Allen Templeton
Project type
Exploratory Research
Gold nano particles have become the subject of great interest due to their unique physical properties which lend them to a wide variety of potential applications such as sensors, optical switches,…

Global and Targeted Proteomic Identification of oxidative modifications.

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Diana Bigelow
Project type
Exploratory Research
Recent research has provided an emerging picture of the significant role of reactive oxygen/nitrogen species (ROS/RNS) and their associated modification of cellular proteins in cellular signaling…

The use of FESEM

Lead Institution
University of South Carolina
Principal Investigator
Xiao-dong Zhou
Project type
Exploratory Research
It is the intent of this proposal to apply for the access of FESEM. FESEM will be used to characterize the grain size, film thickness and surface morphology of thin films, which are fabricated at…
