Optics contamination studies in support of high-throughput EUV lithography tools

March 25, 2011
Author(s)
Shannon B. Hill, Fardina Asikin, Lee J. Richter, Steven E. Grantham, Charles S. Tarrio, Thomas B. Lucatorto, Sergiy Yulin, Mark Schurmann, Viatcheslav Nesterenko, Torsten Feigl
We report on optics contamination rates induced by exposure to broad-bandwidth, high-intensity EUV radiation peaked near 8 nm in a new beamline at the NIST synchrotron. The peak intensity of 50 mW/mm2 allows extension of previous investigations of

Effects of Polyethyleneimine-Mediated Functionalization of Multi-Walled Carbon Nanotubes on Earthworm Bioaccumulation and Sorption by Soils

March 24, 2011
Author(s)
Elijah J. Petersen, Roger A. Pinto, Liwen Zheng, Qingguo Huang, Peter E. Landrum, Walter J. Weber
Carbon nanotubes (CNTs) are often modified for their different intended application potentials to enhance their aqueous stability or change properties such as their surface charge. Such changes may also profoundly impact their environmental behaviors. We

LABORATORY ACCELERATED AND NATURAL WEATHERING OF STYRENE-ETHYLENE-BUTADIENE-STYRENE (SEBS) BLOCK COPOLYMER: ACCELERATION AND CORRELATION

March 23, 2011
Author(s)
Kar T. Tan, Christopher C. White, David J. Benatti, Deborah S. Jacobs, Donald L. Hunston
Indoor accelerated and outdoor field weathering of styrene-ethylene-butadiene-styrene block copolymer have been studied by Fourier transform infrared (FTIR) spectroscopy. In the indoor accelerated experiments, specimens are exposed to ultraviolet-visible

Neutron Imaging of Lithium Concentration in Battery Pouch Cells

March 23, 2011
Author(s)
Daniel S. Hussey, David L. Jacobson, Jason B. Siegel, C. D. Stefan, Xinfan Lin, David Gorsich
This paper shows how neutron radiography can be used for in situ quantification of the lithium concentration across battery electrodes, a critical physical system state. The change in lithium concentration between the charged and discharged states of the

Polarization-Entangled Photon Pairs From a Periodically Poled Cystalline Waveguide

March 23, 2011
Author(s)
Zachary H. Levine, Jingyun Fan, Jun Chen, Alan L. Migdall
A proposal is made for the generation of polarization-entangled photon pairs from a periodically poled crystal. The theory is formulated in terms of colinear propagation for application to waveguides. The key feature of the theory is the use of type 2

Time Through the Air

March 23, 2011
Author(s)
John P. Lowe
A brief history of the NIST WWVB low frequency (LF) radio station. This includes recent attempts at creating a sister station on the eastern side of the United States and future plans for upgrade of the existing station.

Dimensional Metrology of Bipolar Fuel Cell Plates Using Laser Spot Triangulation Probes

March 22, 2011
Author(s)
Balasubramanian Muralikrishnan, Wei Ren, Dennis S. Everett, Eric S. Stanfield, Theodore D. Doiron
As in any engineering component, manufacturing a bipolar fuel cell plate for a polymer electrolyte membrane (PEM) hydrogen fuel cell power stack to within its stated design tolerances is critical in achieving the intended function. In a bipolar fuel cell
