Measuring Hydrogen Deuterium Exchange in Protein Monolayers

October 16, 2008
Author(s)
Jack R. Smith, Marcus T. Cicerone, Curtis Meuse
A non-destructive infrared (IR) spectroscopy assay to measure hydrogen-deuterium exchange (HDX) in surface-adsorbed protein monolayers has been developed. The procedure can be used to measure HDX for different proteins on a variety of materials applied to

Melting Equilibria of the BaF 2 -CuO x System

October 16, 2008
Author(s)
Winnie Wong-Ng, Lawrence P. Cook, J Suh
Since the BaF 2-CuO x system is a limiting binary of the overall quaternary reciprocal Ba,Y,Cu//F,O phase diagram, it provides an important frame of reference for studying the more complicated multi-component system. The phase diagrams of the BaF 2-CuO x

Metastability and Depletion Driven Aggregation

October 16, 2008
Author(s)
Erik K. Hobbie
Depletion driven aggregation in binary colloidal mixtures is studied via the time evolution of the cluster-size distribution and structure factor as the mixtures equilibrate after shear melting. The data suggest a two-stage crystallization process with an

Metrology for Cancer Biomarkers: Affinity Analysis of Human HER2 and Telomerase With IgYs

October 16, 2008
Author(s)
Yan Xiao, G Gannot, M Emmert-Buck, S Srivastava, Paul D. Wagner, Peter E. Barker
To improve quantitation of HER2 and telomerase as cancer biomarkers, we have generated novel avian polyclonal antibodies of IgY isotype for comparison with commercially available mammalian antibodies in cell culture models. IgYs were generated against

Metrology for Remote Sensing Radiometry

October 16, 2008
Author(s)
B. Carol Johnson, Steven W. Brown, Joseph P. Rice
Metrology, the science of measurement, is discussed in terms of measurements of radiant flux and associated quantities. Radiometric measurements are naturally remote, that is, they are non-contact. A broad application is Earth science, as global

Metrology in Support of Trace Explosive Detection Equipment for Airport Security Applications.

October 16, 2008
Author(s)
George A. Klouda, J Greg Gillen, Robert A. Fletcher, E S. Etz, Jennifer R. Verkouteren, R. Michael Verkouteren, E Ferguson
We are working in collaboration with the Transportation Security Agency's Trace Explosive Detection Group to build a chemical metrology program to help support the widespread operational deployment and effective utilization of trace explosives detection

Metrology of Localized Inhomogeneity in Optical Glass

October 16, 2008
Author(s)
Angela Davies
The optical glass industry does not have a standard method of quantiatively evaluating localized inhomogeneities (striae). We are developing an interferometric method and find that the measured wavefront distortion depends on sample position and focus.

Microscale Test Technique and Test Results for Aluminum Thin Films

October 16, 2008
Author(s)
David T. Read, Joseph D. McColskey, Yi-Wen Cheng
A microscale, skyhook-type tensile-test technique has been developed to extend tensile testing to micrometer-scale specimens. This technique has been used to perform tenisle tests of 1 m by 10 m by 180 m gauge sections of electron-beam-evaporated aluminum

Miniature Fourier Transform Instrument for Radiation Thermometry

October 16, 2008
Author(s)
F J. Dunmore, Leonard Hanssen
A miniature Fouier transform (FT0 spectrometer was evaluated as a device for remotely measuring the temperature of a high stability/emissivity blackbody. The device, commercially manufactured by Photonex LTD.,* is based on the novel design of a polarizing

Model for the Asymmetric DC and Fluctuating Conduction of an Ion Channel

October 16, 2008
Author(s)
B Robertson, John J. Kasianowicz
A model for the asymmetric DC conduction of an ion channel is compared with measurements of the ionic current carried by an aqueous potassium chloride solution through ion channels formed by alpha hemolysin in a lipid bilayer. The dependence of the current

Modeling Core-Hole Screening in Core-Excitation Spectroscopies

October 16, 2008
Author(s)
Eric L. Shirley, J A. Soininen, J J. Rehr
We consider screening of the core-hole potential experienced by the ejected electron in core-excitation processes. This potential affects near-edge structure strongly, but it appears difficult to consistently obtain reliable screened core-hole potentials

Modeling Molecular Recognition: Theory and Application

October 16, 2008
Author(s)
K L. Mardis, R Luo, L David, M Potter, A J. Glemza, G F. Payne, M K. Gilson
Efficient, reliable methods for calculating the binding affinities of noncovalent complexes would allow advances in a variety of areas such as drug discovery and separation science. We have recently described a method that accommodates significant physical

Modeling Superconformal Electrodeposition Using an Open Source PDE Solver

October 16, 2008
Author(s)
Daniel Wheeler, Jonathan E. Guyer
Superconformal electrodeposition enables the void-free filling of high aspect ratio features such as trenches or vias in the Damascene metallization process. Superconformal electrodeposition, also known as superfill, occurs when particular combinations of
