Silicon Nanotips for Enhanced Electron Emission

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Glen Dunham
Project type
Exploratory Research
The EMSL microfabrication capabilities will be used to create wafers covered with pyramidal nanotips. These surfaces will be tested elsewhere for electron emission.

Inelastic Electron Scattering Cross Section Measurements in Liquid Water

Lead Institution
Wadsworth Center
Principal Investigator
Craig Brown
Project type
Exploratory Research
The primary objective of this work is to measure inelastic electron scattering cross sections as a function of energy and angle in liquid water in the energy range of 30 keV. The short term goal…

Highly Selective Monolayer Sorbents for Advanced Analytical Applications

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
John Bays
Project type
Exploratory Research
Molecular templating of self-assembled monolayers on a mesoporous silica may be used for highly selective detection of relatively small molecules. By using different templating processes and a…

Dynamics studies of surface-induced dissociation of polyatomic
ions

Lead Institution
Office of Fellowship Program
Principal Investigator
Talayeh Rezayat
Project type
Exploratory Research
Ion- surface collisions have long been used for surface characterization and have recently been extended to the analysis of projectile ions as well via their dissociations on surface impact,…

Developing high-performance parallel languages on the SGI Altix

Lead Institution
University of California, Berkeley
Principal Investigator
Dan Bonachea
Project type
Exploratory Research
Our group is working on developing high-performance parallel languages (specifically UPC and Titanium) for modern supercomputers. We'd like to port our implementation of GASNet (a unified, high…

1H AND 13C NMR STUDY OF BRODIFACOUM STEREOCHEMISTRY AND STRUCTURE

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
John Cort
Project type
Exploratory Research
Brodifacoum is a lipid-soluble warfarin derivative that inhibits vitamin K epoxide reductase (VKOR) and exhibits potent anticoagulant activity. Because of its chemical stability and use in numerous…

Solid State NMR Characterization of Hydrogenase

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Wendy Shaw
Project type
Exploratory Research
Hydrogenase is a naturally occurring enzyme that efficiently converts H2->2H+ + 2e- and is reversible. Producing synthetic catalysts with these properties is highly desirable, but current analogs…

Isolation of Isotopically-Labeled Nucleic Acids

Lead Institution
Washington State University Tri-Cities
Principal Investigator
Kathleen McAteer
Project type
Exploratory Research
The primary goal of this project is to develop and implement new approaches for using isotopic labels in NMR-based DNA structure determination. 13C and 15N-labeled RNA and DNA will be isolated from…

Metal Ion Binding and Substrate Specificity in Hydroquinone Dioxygenases

Lead Institution
Whitman College
Principal Investigator
Timothy Machonkin
Project type
Exploratory Research
Bacterial pathways for the catabolism of aromatic hydrocarbons are of interest for use in bioremediation of pollutants such as chlorinated arenes. The oxidative ring cleavage step is often the major…

Advanced IMPROVE Studies

Lead Institution
Desert Research Institute
Principal Investigator
Douglas Lowenthal
Project type
Exploratory Research
The proposed collaboration with Dr. Lizabeth Alexander of PNNL will enable continuous measurement of size-resolved aerosol chemical composition using the EMSL high resolution time-of-flight Aerosol…

Fluorescence Microscopy of Cells and Particles.

Lead Institution
Harvard University
Principal Investigator
Gary Holtom
Project type
Exploratory Research
Response of live cells to particles will be studied by analyzing images taken with the fluorescence microscope.
