11. Two dimensional spectroscopic imaging of individual ferromagnetic nanostripes
Topic: Environment/Climate
Published: 11/6/2012
Authors: Han-Jong H. Chia, Feng Guo, Lyubov Belova, Robert D McMichael
Abstract: We use ferromagnetic resonance force microscopy (FMRFM) to spectroscopically image the edge modes in individual 700 and 400 nm wide Permalloy stripes with a spatial resolution on the order of 200 nm. The imaging clearly identies some resonances as ...

12. SCIENCE-BASED METRICS FOR PRODUCT SUSTAINABILITY ASSESSMENT
Topic: Environment/Climate
Published: 9/30/2012
Author: Barbara C. 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 ...

13. Exploring background variability of a low-level (quartz) gas proportional counter using pulse shape and distribution analysis
Topic: Environment/Climate
Published: 8/29/2012
Authors: George A Klouda, James J Filliben
Abstract: Low-level gas proportional counting presents special challenges to the measurement process. Generally, measurement systems for this purpose have unique signal-processing capabilities through specialized electronics and software for maintaining a sta ...

14. 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 ...

15. Proposal for a standardized test artifact for additive manufacturing machines and processes
Topic: Environment/Climate
Published: 8/15/2012
Authors: Shawn P Moylan, John A Slotwinski, April Lynne Cooke, Kevin K Jurrens, M Alkan Donmez
Abstract: Historically, standardized test parts are used to quantitatively evaluate the performance of a machine or process. While several different additive manufacturing (AM) test parts have been developed in the past, there are no current standard test par ...

16. Characterization of Surface Accumulation and Release of Nanosilica During Irradiation of Polymer Nanocomposites with Ultraviolet Light
Topic: Environment/Climate
Published: 8/12/2012
Authors: Tinh Nguyen, Bastien T. Pellegrin, Coralie Bernard, Savelas A Rabb, Paul E Stutzman, Justin M Gorham, Xiaohong Gu, Lee Lijian Yu, Joannie W Chin
Abstract: Nanofillers are increasingly used for enhancing multiple properties of polymeric materials in many applications. However, polymers are susceptible to photodegradation by solar ultraviolet (UV) radiation Therefore, nanofillers in a polymer nanocompos ...

17. 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 ...

19. 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 ...

20. 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 ...
