Chemical Warfare Agent Detection Using MEMS Microsensor Arrays

August 1, 2005
Author(s)
Douglas C. Meier, C J. Taylor, Richard E. Cavicchi, Edward White V, M W. Ellzy, K B. Sumpter, Stephen Semancik
Chemical sensors capable of accurate detection of trace quantities of chemical warfare (CW) agents would provide a potent tool for perimeter security, treaty verification, battlefield threat detection, and the protection of civilians in public places

Chemical Warfare Agent Detection Using MEMS-Compatible Microsensor Arrays

August 1, 2005
Author(s)
Douglas C. Meier, C J. Taylor, Richard E. Cavicchi, Edward White, M W. Ellzy, K B. Sumpter, Stephen Semancik
Microsensors have been fabricated consisting of TiO2 and SnO2 sensing films prepared by chemical vapor deposition (CVD) on MEMS- (micro-electromechanical systems) compatible array platforms. Response measurements from these devices to the CW agents GA

Compositional Control in Electrodeposited Co x Pt -x Films.

August 1, 2005
Author(s)
J Mallett, Erik B. Svedberg, S Sayan, Alexander J. Shapiro, L Wielunski, T. E. Madey, P J. Chen, William F. Egelhoff Jr., Thomas P. Moffat
Electrochemical co-deposition of Co(subscript x)Pt(subscript 1-x) alloys is demonstrated at potentials positive to that required to deposit elemental cobalt (underpotential co-deposition). Co-deposition is atributed to the negative enthalpy of Co(subscript

Computer Security Division 2004 Annual Report

August 1, 2005
Author(s)
Tanya L. Brewer
This report covers the work conducted within the National Institute of Standards and Technology's Computer Security Division during Fiscal Year 2004. It discusses all projects and programs within the Division, staff highlights, and publications. For many

Conclusions and Recommendations from the Pentagon Crash

August 1, 2005
Author(s)
Paul K. Mlakar, D O. Dusenberry, J R. Harris, G A. Haynes, Long Phan, M A. Sozen
The devastation in the September 11, 2001, terrorist attack on the Pentagon was reduced by the building s resilient structural system. The continuity, redundancy, and energy-absorbing capacity embodied in this system should be incorporated in structures

Consumer Package Labeling Guide: Labeling by Weight

August 1, 2005
Author(s)
K M. Dresser
[Withdrawn (February 13, 2018)] Guide is intended to provide manufacturers, packers, distributors, and retailers of packaged products with information about the labeling requirements for commodities that are sold by weight in the consumer marketplace. The

Consumer Packaging Labeling Guide: Selling by Volume

K M. Dresser
[Withdrawn (February 13, 2018)] Guide is intended to provide manufacturers, packers, distributors, and retailers of packaged products with information about the labeling requirements for commodities that are sold by volume in the consumer marketplace. The

CRYSTALLOGRAPHIC CHANGES IN ELECTRICALLY FATIGUED ACTUATORS

August 1, 2005
Author(s)
Jens Mueller, Davor Balzar, Stephanie A. Hooker
Many new applications are emerging for piezoelectric ceramics, including adaptive structures, vibration isolation, and nano-robotics. In these instances, actuators will likely be operated at higher electric fields than in conventional applications in order

Description of Structural Damage Caused by the Terrorist Attack on the Pentagon

August 1, 2005
Author(s)
Paul K. Mlakar, D O. Dusenberry, J R. Harris, G A. Haynes, Long Phan, M A. Sozen
On September 11, 2001, an airliner was intentionally crashed into the Pentagon. It struck at the first elevated slab on the west wall, and slid approximately 310 ft (94.5 m) diagonally into the building. The force of the collision demolished numerous

Direct Correlation of Organic Semiconductor Film Structure to Field-Effect Mobility

August 1, 2005
Author(s)
Dean M. DeLongchamp, S Sambasivan, Daniel A. Fischer, Eric K. Lin, Paul C. Chang, A R. Murphy, J M. Frechet, V Subramanian
Recent efforts towards the large-scale adoption of organic electronics have focused on maximizing device performance using new molecular designs and processing strategies. However, rational design and systematic progress are hindered by insufficient

Effect of a Calcium Pre-Rinse on Salivary Fluoride After a 228-ppm Fluoride Rinse

August 1, 2005
Author(s)
Gerald L. Vogel, Laurence C. Chow, Clifton M. Carey, Gary E. Schumacher, Shozo Takagi
The objective of this study was to determine if a concentrated calcium pre-rinse given before a F rinse would cause an increase in the post rinse salivary fluoride (F). The three pre-rinses tested, (30, 150 or 300) mmol/L calcium as calcium lactate

Embeding MPEG-7 Metadata Within a Media File Format

August 1, 2005
Author(s)
Wo L. Chang
Embedding metadata within a media file format becomes evermore popular for digital media. Traditional digital media files such as MP3 songs and JPEG photos do not carry any metadata structures to describe the media content until these file formats got

Enhancements to GPS Operations and Clock Evaluations using a Total Hadamard Deviation

August 1, 2005
Author(s)
David A. Howe, Ron Beard, C. A. Greenhall, F. Vernotte, W. J. Riley, Trudi K. Peppler
We describe a method based on the Total deviation approach whereby we improve the confidence of the estimation of the Hadamard deviation that is used primarily in GPS operations. The Hadamard-total deviation described in this paper provides a significant

Gradient Chemical Micropatterns: A Reference Substrate for Surface Nanometrology

August 1, 2005
Author(s)
D Julthongpiput, Michael J. Fasolka, Wenhua Zhang, Tinh Nguyen, Eric J. Amis
We present fabrication routes for a new type of surface specimen that exhibits a micropattern with a gradient in chemical contrast between the pattern domains. Design elements in the specimen allow chemical contrast in the micropattern to be related to

Implementation and Application of a Microstructurally Based Orthotropic Hyperelastic Model of Pulmonary Artery Mechanics under Normotensive and Hypertensive Conditions

August 1, 2005
Author(s)
Yang Zhang, Martin Dunn, Elizabeth S. Drexler, Christopher N. McCowan, Andrew Slifka, Dunbar Ivy, R Shandas
We implemented, validated, and applied a microstructurally based orthotropic hyperelastic constitutive model to simulate pulmonary artery mechanics under normotensive and hypoxic hypertensive conditions. The configuration of the model microstructure is a
