Medicine Container Diagnosis

Lead Institution
XL Science & Technology
Principal Investigator
Y Peng
Project type
Exploratory Research
Use of envioronmental SEM for non-destructive diagnosis of medicine container without open or breaking medicine vial. Environmental SEM is best suited and a necessity. Chemical make up of container:…

Measurement of the Two-Photon Absorption Cross-Section of Natural Dyes

Lead Institution
Missouri Western State University
Principal Investigator
Jeffrey Woodford
Project type
Exploratory Research
We propose to measure the two-photon absorption cross-section of natural anthocyanidin chromophores with an aim towards two-photon confocal microscopy imaging of living plant tissue. The cross…

From Activity to ORF

Lead Institution
Washington University in St. Louis
Principal Investigator
Daniel Kohl
Project type
Exploratory Research
THE PROBLEM: There are many known activities, the genes for which are unknown Although vast databases of DNA sequences are now available for many organisms, there are still many known protein…

molecular electronics

Lead Institution
University of Colorado
Principal Investigator
Sandrine Rubio
Project type
Exploratory Research
We have synthetized and are now characterizing ionic compounds expected to be useful in single-molecule electronics (A.M. Rouhi, C&EN, July 30, 2001, p46). Our samples seem to be pure by HLPC but…

Nonparametric Classification Using Parallel Systems (nsd2)

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Gregg Petrie
Project type
Exploratory Research
We will use a parallel computing system to classify an image nonparametrically and compare the results to those generated by a conventional parametric supervised classification. Hopefully the…

Non-Invasive Monitoring for Occupational Exposure to Metals

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Charles Timchalk
Project type
Exploratory Research
The assessment of the potential for health effects, and the need for protective measures requires the accurate measurement of exposure, and the ability to translate these measurements into dose. …

Cu Interconnect Structure in the FESEM

Lead Institution
Washington State University
Principal Investigator
David Field
Project type
Exploratory Research
Cu interconnect structure will be imaged using the LEO 982 FESEM. Orientations from select locations will be measured using EBSD. On a return trip, we will examine the evolved structure after…

Photolithography to form microcontact printing tools

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Barbara Tarasevich
Project type
Exploratory Research
Objectives are to use the photolithography facility in EMSL 1304 clean room to form patterned resists on silicon wafers.

AES Study of Chemical Segregation in the Ti-Pt-PZT system for MEMS devices

Lead Institution
Washington State University
Principal Investigator
David Bahr
Project type
Exploratory Research
In past investigations between WSU and EMSL, XPS analysis has provided evidence that Pb has diffused to the Ti/Pt interface in a Si/SiO2/Ti/Pt/PZT stack used in a MEMS microengine. Pb diffusion…

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…
