The NIST EUV facility for advanced photoresist qualification using the witness-sample test

August 29, 2011
Author(s)
Steven E. Grantham, Charles S. Tarrio, Shannon B. Hill, Lee J. Richter, J. van Dijk, C. Kaya, N. Harned, R. Hoefnagels, M. Silova, J. Steinhoff
Before being used in an extreme-ultraviolet (EUV) scanner, photoresists must first be qualified to ensure that they will not excessively contaminate the scanner optics or other parts of the vacuum environment of the scanner. At the National Institute of

Validation of Uniaxial Data Beyond Uniform Elongation

August 29, 2011
Author(s)
Mark A. Iadicola
Uniaxial testing is one of the simplest methods used to determining mechanical properties for sheet metals, but the classic test does not determine properties to sufficiently high strain levels for use in models of very large deformations such as forming

Characterizing the Mechanical Properties and Degradation of Thin Polymer Membranes

August 28, 2011
Author(s)
Christopher M. Stafford, Jun Y. Chung, Junghyun Lee
The elasticity, strength, and toughness of thin polymer membranes are of considerable interest since direct knowledge of these key mechanical properties can provide insight into performance, durability, and underlying degradation mechanisms that occur over

Development of a Candidate Reference Measurement Procedure for the Determination of Phenytoin, Phenobarbital, Lamotrigine, and Topiramate in Human Serum Using Isotope-Dilution Liquid Chromotography/Tandem Mass Spectrometry

August 28, 2011
Author(s)
Susan Tai, Karen W. Phinney, Chia-Yi Yeh
Phenytoin (PHT), phenobarbital (PHB), lamotrigine (LTG), and topiramate (TPM) are some of the most widely used antiepileptic drugs (AEDs). Monitoring of their concentrations in serum is important for the treatment of epilepsy. A candidate reference

Modeling electromigration using the peridynamics approach

August 28, 2011
Author(s)
David T. Read, Walter Gerstle, Vinod K. Tewary
This chapter presents a summary of the information and reasoning needed to justify learning about peridynamics for the purpose of analyzing electromigration and provides guidance for the development of a complete peridynamics analysis. The additions needed

Fracture of X100 Pipeline Steel: Combined Experimental-Numerical Process

August 26, 2011
Author(s)
Mordechai Szanto, Christopher N. McCowan, Elizabeth S. Drexler, Joseph D. McColskey
Accurate characterization of material fracture properties is necessary for reliable numerical prediction of rupture in gas pipelines. In the current work the ductile fracture properties for high strength X100 pipeline steel, was evaluated, using

Magnetic Order of the Hexagonal Rare Earth Manganite Dy 0.5 Y 0.5 MnO 3

August 26, 2011
Author(s)
Joel Helton, Deepak Singh, Harikrishnan S. Nair, Suja Elizabeth
Hexagonal Dy 0.5Y 0.5MnO 3, a multiferroic rare earth manganite with geometrically frustrated antiferromagnetism, has been investigated with neutron diffraction measurements. Below 2.4 K magnetic order is observed on both the Mn (antiferromagnetic) and Dy

Effect of Regioregularity on the Semicrystalline Structure of Poly(3-hexylthiophene

August 25, 2011
Author(s)
Chad R. Snyder, Dean M. DeLongchamp, Jessica S. Henry
The impact of regioregularity in poly(3-hexylthiophene-2,5-diyl) (P3HT) on crystallization behavior and quantitative limits to possible crystal sizes is discussed, and it is explained why regioregularities must be reported for any study to be properly

Spin Dependent Charge Pumping in SiC Metal-Oxide-Semiconductor Field-Effect-Transistors

August 25, 2011
Author(s)
Brad Bittel, Patrick Lenahan, Jason Ryan, Jody Fronheiser, Aivars Lelis
We demonstrate a very powerful electrically detected magnetic resonance (EDMR) technique, spin dependent charge pumping (SDCP) and apply it to 4H SiC metal-oxide-semiconductor field-effect-transistors (MOSFETs). SDCP combines a widely used electrical

Hydrogen Spillover Effect of Pt-Doped Activated Carbon Studied by Inelastic Neutron Scattering

August 24, 2011
Author(s)
Cheng-Si Tsao, Yun Liu, Haw-Yeu Chuang, Huan-Hsiung Tseng, Tsan-Yao Chen, Chien-Hung Chen, Ming-Sheng Yu, Qixiu Li, Angela Lueking, Sow-Hsin Chen
We employed inelastic neutron scattering (INS) method to directly monitor the change of molecular hydrogen in the Pt-doped activated carbon (Pt/AC) samples and provide very conclusive evidence that significant hydrogen atoms can diffuse to the carbon

Selective Oxidation of Glycerol by Highly Active Bimetallic Catalysts at Ambient Temperature under Base Free Conditions

August 24, 2011
Author(s)
Andrew A. Herzing, Gemma L. Brett, Peter Miedziak, Nikolaos Dimitratos, Meenakshisundaram Sankar, Marco Conte, Jose A. Lopez-Sanchez, David W. Knight, Stuart H. Taylor, Graham J. Hutchings, Qian He, Christopher J. Kiely
AuPt or AuPd nanoparticles when supported on Mg(OH)2 are highly active for the selective oxidation of glycerol under base-free conditions at ambient temperatures. When bimetallic particles with the appropriate composition are prepared, catalysts with a

Nanometer Size Magnetic Domains and Coherent Magnetization Reversal in a Giant Exchange Bias System

August 23, 2011
Author(s)
C. Dufour, M .R. Fitzsimmons, Julie Borchers, M. Laver, Kathryn L. Krycka, K. Dumesnil, Shannon M. Watson, Wangchun Chen, S. Singh
We present compelling evidence obtained with small angle scattering of unpolarized and polarized neutron beams the magnetization reversal occurs via formation of 10-100's nm sized magnetic domains in an exchanged biased DyFe 2/YFed2^ superlattice. The
