Report on the Static Analysis Tool Exposition (SATE) IV

February 4, 2013
Author(s)
Vadim Okun, Aurelien M. Delaitre, Paul E. Black
The NIST SAMATE project conducted the fourth Static Analysis Tool Exposition (SATE IV) to advance research in static analysis tools that find security defects in source code. The main goals of SATE were to enable empirical research based on large test sets

Spontaneous wrinkling in azlactone-based functional polymer thin films in 2d and 3d geometries for guided nanopatterning

February 4, 2013
Author(s)
Muruganathan Ramanathan, Bradley S. Lokitz, Jamie M. Messman, Christopher Stafford, S. M. Kilbey
We report a simple, one step process for developing wrinkling patterns in azlactone-based polymer thin films and brushes in 2D and 3D surfaces. The polymer used in this work wrinkles spontaneously upon deposition and solidification on a substrate without

Thermococcus kodakarensis DNA replication

February 2, 2013
Author(s)
Zvi Kelman, Lori Kelman, Zhuo Li
DNA replication plays an essential role in all life forms. Research on archaeal DNA replication began about twenty years ago. Progress was hindered, however, by the lack of genetic tools to supplement the biochemical and structural studies. This has

A One-Kilogram Quartz Resonator as a Mass Standard

February 1, 2013
Author(s)
David A. Howe, J Vig
The unit of mass, the kilogram, is the last remaining SI base unit defined by an artifact” [1]. This artifact, the primary mass standard, suffers from long term instabilities that are neither well understood, nor easily monitored [2]. A mass standard

Backcontact CdSe/CdTE Windowless Solar Cells

February 1, 2013
Author(s)
Donguk Kim, Carlos M. Hangarter, Ratan K. Debnath, Jong Y. Ha, Carlos R. Beauchamp, Matthew D. Widstrom, Jonathan E. Guyer, Nhan Van Nguyen, B. Y. Yoo, Daniel Josell
This paper details the fabrication and properties of CdSe/CdTe thin film photovoltaic devices with a dual back contact geometry. Device fabrication involves cadmium selenide electrodeposition on one of two interdigitated electrodes on a pre-patterned

Comparison of Publicly Available Methodologies for Development of Geologic Storage Estimates for Carbon Dioxide in Saline Formations

February 1, 2013
Author(s)
Angela L. Goodman, Grant Bromhal, Brian Strazisar, Traci Rodosta, William F. Guthrie, George Guthrie
High-level estimates of CO2 storage resource for application to saline formations at the national, regional, and basin scale are required to assess the potential for carbon capture, utilization, and storage technologies to reduce CO2 emissions. Both

Effects of dual antibacterial agents MDPB and nano-silver in primer on microcosm biofilm, cytotoxicity and dentin bond properties

February 1, 2013
Author(s)
Ke Zhang, Lei Cheng, Satoshi Imazato, Joseph M. Antonucci, Nancy Lin, Sheng Lin-Gibson, Yuxing Bai, Hockin H. Xu
Objectives: Secondary caries at restoration margins is the main reason for restoration failure. Antibacterial bonding agents are promising to inhibit biofilm acids at the tooth-restoration interfaces. The objective of this study was to investigate the

Improving Concrete Bridge Decks with Internal Curing

February 1, 2013
Author(s)
Jason Weiss, Dale P. Bentz, Carmelo DiBella
Transportation agencies strive to provide durable, long lasting concrete bridge decks. While high performance concrete is frequently desired due to its resistance to chloride ingress and corrosion, these mixtures are often accompanied with an increased

Interfacial Mechanical Properties of n-Alkylsilane Monolayers on Silicon Substrates

February 1, 2013
Author(s)
Brian G. Bush, Frank W. DelRio, Cherno Jaye, Daniel A. Fischer, Robert F. Cook
The interfacial properties of n-alkylsilane self-assembled monolayers on silicon were investigated by normal force spectroscopy and lateral force measurements and correlated with molecular structure via near-edge X-ray absorption fine structure (NEXAFS)

NIST Gold Nanoparticle Reference Materials Do Not Induce Oxidative DNA Damage

February 1, 2013
Author(s)
Bryant C. Nelson, Donald H. Atha, John T. Elliott, Bryce J. Marquis, Elijah J. Petersen, Danielle Cleveland, Stephanie S. Watson, I-Hsiang Tseng, Andrew Dillon, Melissa Theodore, Joany Jackman
Well-characterized, nanoparticle reference materials are urgently needed for nanomaterial toxicity studies. The National Institute of Standards and Technology has developed three gold nanoparticle (AuNP) reference materials (10 nm, 30 nm, 60 nm) to address
