Critical Role of Side-Chain Attachment Density on the Order and Device Performance of Polythiophenes

October 30, 2007
Author(s)
Regis J. Kline, Dean DeLongchamp, Daniel A. Fischer, Eric K. Lin, Lee J. Richter, Michael L. Chabinyc, Martin Heeney, Iain McCulloch
High performance, solution processable semiconductors are critical to the realization of low cost, large area electronics. We show that a signature molecular packing motif - side-chain interdigitation - correlates to high performance for a large and

Compositional Control in Electrodeposited Ni (subscript x) Pt (subscript 1-x) Films

October 29, 2007
Author(s)
J Mallett, Erik B. Svedberg, John E. Bonevich, Alexander J. Shapiro, William F. Egelhoff Jr., Thomas P. Moffat
Electrochemical co-deposition of a series of fcc Ni(subscript x)PT(subscript 1-x) alloys is demonstrated. The alloy composition is a monotonic function of potential. The Pt-rich Ni(subscript x)PT(subscript 1-x) alloys are formed at potentials positive to

Effect of Static Analysis Tools on Software Security: Preliminary Investigation

October 29, 2007
Author(s)
Vadim Okun, William F. Guthrie, Romain Gaucher, Paul E. Black
Static analysis tools can handle large-scale software and find thousands of defects. But do they improve software security? We evaluate the effect of static analysis tool use on software security in open source projects. We measure security by

Pulsed Laser Deposition and Characterization of Hf-based High-k Dielectric Thin Films

October 26, 2007
Author(s)
Joseph C. Woicik, M A. Sahiner, Timothy Kurp, Jeffrey Serfass, Marc Aranguren
The continuous downward scaling of the complementary metal oxide semiconductor (CMOS) devices has enabled the Si-based semiconductor industry to meet the technological requirements such as high performance and low power consumption. However, the ever

Technical Variation in Modeling the Joint Expression of Several Genes

October 25, 2007
Author(s)
Walter S. Liggett Jr
Biological studies based on expression microarrays often depend crucially on comparison of expression measurements that are subject to technical variation associated with changes in time, laboratory or other measurement conditions. If a biological study

The Common Vulnerability Scoring System (CVSS)

October 25, 2007
Author(s)
Shirley M. Radack
This bulletin summarizes the guidance developed by NIST and published in NISTIR 7435 to help IT managers to make sense of data about the vulnerabilities of their information systems and to take appropriate actions that will protect their systems and

Thermodynamics of Enzyme Catalyzed Reactions: Part 7 - 2007 Update

October 25, 2007
Author(s)
Robert N. Goldberg, Yadu D. Tewari, Talapady N. Bhat
This review serves to update previously published evaluations of equilibrium constants and enthalpy changes for enzyme catalyzed reactions. For each reaction the following information is given: the reference for the data; the reaction studied; the name of

Evaluating Entity-Based Sensemaking Tools for Intelligence Analysis

October 24, 2007
Author(s)
Eric Bier, Theresa O'Connell, Yee-Yin Choong, Christiaan Royer, Randy Gobbel
Intelligence analysts regularly face difficult tasks. Given many potentially relevant documents and facts, they must find the most relevant, organize them, and make sense of them. New software technologies are being developed to help. Given the complexity

Information Technology Laboratory Brochure

October 24, 2007
Author(s)
Vijay Tirumala, R A. Pai, Sumit Agarwal, Curran Chandler, Gaurav Bhatnagar, Alvin Omang, Eric K. Lin, J J. Watkins
Well ordered mesoporous silica films were prepared by infusion and selective condensation of Si alkoxides within pre-organized block copolymer/homopolymer blend templates using supercritical CO2 as the delivery medium. The morphologies of mesoporous silica

Electron Impact Ionization of Metastable Rare Gases: He, Ne and Ar

October 23, 2007
Author(s)
M A. Ali, Philip M. Stone
Ionization cross sections by electron impact of atoms are important quantities needed for modeling of low temperature plasmas and gas discharges. Although experimental and theoretical studies of ionization of ground states of atoms have been extensive

Fatigue Crack Growth Rates in Pipeline Steels Using Curved M(T) Specimens

October 23, 2007
Author(s)
Philippe P. Darcis, John M. Treinen, Joseph D. McColskey
This study presents fatigue data for two different ferrite-pearlite pipeline steels. A fatigue crack growth test for full thickness curved pipeline samples was developed using a Middle Tension, M(T), type specimen. Also, FEA (Finite Element Analyses) were
