Cellular responses to ionizing radiation as examined by FTIR.

Lead Institution
Middle East Technical University
Principal Investigator
Feride Severcan
Project type
Exploratory Research
Currently, the standards for human exposure to ionizing radiation are set by extrapolating data obtained in the high-dose regime to the low-dose regime where the biological responses are below…

Surface Analysis of Polyurethanes

Lead Institution
University of Central Florida
Principal Investigator
Jeffrey Ramsdell
Project type
Exploratory Research
This is continuing study of the surface domains of segmented polyurethane materials. The surface chemical structure, morphology, and mechanical response of these materials is being investigated…

Continued investigation into the spinel nickel-cobalt oxide system.

Lead Institution
Applied Materials
Principal Investigator
Robert Owings
Project type
Exploratory Research
Past work with the nickel cobalt oxide thin films has yielded new and interesting data with respect to the nature of charge motion and the charge distribution within the spinel lattice. The nickel…

Modification and decay of radiation defects in tooth enamel

Lead Institution
National Institute of Chemical Physics and Biophysics
Principal Investigator
Georg Liidja
Project type
Exploratory Research
Stable carbonate radicals created in tooth enamel by ionizing irradiation from soil are used in dating palaeontological artefacts up to Megayears. The number of radicals as measured with electron…

Phosphoproteome determination of LPA treated osteocytes

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Norman Karin
Project type
Large-Scale EMSL Research
Osteocytes arise from bone-forming osteoblasts that become surrounded by mineralized matrix and comprise greater than 90% of all bone cells. Osteocytes form a junctionally-connected sensory network…

Mass Determination of Cyclic Siloxane

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
David Nelson
Project type
Exploratory Research
A presumed cyclic siloxane has been isolated from the polymerization of a phenolic diallyl compound and silane hydride under catalytic hydrosilylation conditions. This type of cyclic component is…

Determination of Metal Dispersion Values

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
David King
Project type
Exploratory Research
Project objective is to look at alternate methods of adding active metals to catalyst supports. The purpose for the project is to determine the best method in terms of maximizing exposed metal…

High pressure VLS synthesis of silicon nanowires

Lead Institution
Portland State University
Principal Investigator
Joo Chan
Project type
Exploratory Research
Silicon nanowires synthesized via supercritical cyclohexane solvent at a high temperature of 450C and pressures of 200bar will be studied. Doping of the silicon nanowires with p- and n- dopant during…

I am currently working on a project for Dr. Yan of Portland State University. This project involves making molecularly imprinted polymers for use as optical detectors. In specific, I want to make…

The Measurement of Low Energy Ion Sputtering Yields Utilizing RBS

Lead Institution
NASA Glenn Research Center
Principal Investigator
Maris Mantenieks
Project type
Exploratory Research
Sputtering, a process by which a target is removed by an impinging ion, has been studied in great detail since the early sixties. Despite this, the need exists for accurate sputtering yield…

Photoelectron Spectroscopy of Group VI transition Metal oxygen clusters
