1. SCIENCE-BASED METRICS FOR PRODUCT SUSTAINABILITY ASSESSMENT
Topic: Environment/Climate
Published: 9/30/2012
Author: Barbara Cassard Lippiatt
Abstract: Consumers and manufacturers need compelling metrics, tools, and data supporting investments in sustainable products. Today’s marketplace is fraught with sustainability claims that are often based on incomplete, anecdotal evidence that is difficult to ...

2. Service Life Prediction for Sealants
Topic: Environment/Climate
Published: 8/27/2012
Authors: Christopher C White, Donald Lee Hunston, Kar Tean Tan
Abstract: Previous industry consensus postulated that four elements of the weather: Temperature, Humidity, Ultraviolet Radiation, and Mechanical loading were responsible for the majority of the changes observed in sealants exposed to outdoor weathering. The N ...

3. Properties of Metal Powders for Additive Manufacturing: A Review of the State of the Art of Metal Powder Property Testing
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7873
Topic: Environment/Climate
Published: 8/3/2012
Authors: April Lynne Cooke, John A Slotwinski
Abstract: This report investigates the current state-of-the-art methods for determining the properties of metal powders. This assessment evaluates both existing standards that provide guidance for powder property measurement methods, as well as technical p ...

4. The winter time South Pole tropospheric water vapor column: Comparisons of radiosonde and recent terahertz radiometry, use of the saturated column as a proxy measurement; and inference of decadal trends
Topic: Environment/Climate
Published: 7/7/2012
Authors: Richard Addison Chamberlin, Erich N Grossman
Abstract: We use a fifty year record of winter time radiosonde observations at the South Pole to estimate the precipitable water vapor column (PWV) over the entire period. Humidity data from older radiosondes is of limited reliability; however, we think an est ...

5. Innovative Approach to Rapid Growth of Highly Clay-Filled Coatings on Porous Polyurethane Foam
Topic: Environment/Climate
Published: 6/11/2012
Authors: Yeon Seok Kim, Richard H Harris, Rick D Davis
Abstract: : An innovative twist to fabricating layer-by-layer coatings resulted in transparent, high-content clay coatings on porous polyurethane foam. The addition of an anionic poly(acrylic acid) (PAA) monolayer between anionic clay and cationic branched-pol ...

6. A systematic approach to the study of accelerated weathering in building joint sealants
Topic: Environment/Climate
Published: 5/1/2012
Authors: Christopher C White, Donald Lee Hunston, Kar Tean Tan, James J Filliben
Abstract: An accurate service life prediction model is urgently needed for building joint sealants to reduce the enormous cost associated with long-term field weathering. A stepping stone to the success of this effort is the precise control of environmental va ...

7. Measurements, Standards, and Data In Support of Sustainable Materials and Materials-Related Technologies
Topic: Environment/Climate
Published: 4/1/2012
Authors: Dianne L Poster, Michael J Fasolka, Richard R Cavanagh, Ellyn S. Beary
Abstract: Industry is increasingly aware that sustainability combines environmental, societal, and economic considerations in product development and that this linkage, while driving improved performance, can pose both a business opportunity and a challenge. ...

8. Evaluation of Fusion Methods for Latent Fingerprint Matchers
Topic: Environment/Climate
Published: 3/29/2012
Author: Vladimir N Dvornychenko
Abstract: Matcher fusion is a recognized approach for improving biometric system performance. Our interest in fusion was largely to determine how much performance “headroom” exists with current matcher technology. We employed five latent fingerprint matchers, ...

9. SEM imaging of ultra-high aspect ratio hole features
Topic: Environment/Climate
Published: 3/29/2012
Authors: John S Villarrubia, Aron Cepler, Benjamin D. Bunday, Bradley Thiel
Abstract: In-line, non-destructive process control metrology of high aspect ratio (HAR) holes and trenches has long been a known gap in metrology. Imaging the bottoms of at-node size beyond 10:1 AR contact holes in oxide has not yet been demonstrated. Neverth ...

10. Mechanical Properties Testing for Metal Parts Made via Additive Manufacturing: A Review of the State of the Art of Mechanical Property Testing
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7847
Topic: Environment/Climate
Published: 3/26/2012
Authors: John A Slotwinski, April Lynne Cooke, Shawn P Moylan
Abstract: Determining the properties of the powder used for metal‐based additive manufacturing, as well as the properties of the resulting bulk metal material, is a necessary condition for industry to be able to confidently select powder and produce cons ...
