Author(s)
Brian B. Maranville, William D. Ratcliff, Paul A. Kienzle
The online data reduction service reductus transforms measurements in experimental science from laboratory coordinates into physically meaningful quantities with accurate estimation of uncertainties based on instrumental settings and properties. This

Service Life Prediction Models to Predict Building Skin Failures

October 1, 2018
Author(s)
Christopher C. White, Donald L. Hunston, Adam L. Pintar
Determination of the in-service performance and failure of a building envelope material exposed to outdoor weathering has been a significant research goal for the last 100 years. Typically, estimations of the time to failure or durability of a material is

Spectroscopic Compton Imaging of Prompt Gamma Emission at the MeV Energy Range

October 1, 2018
Author(s)
Haijian Chen, Huaiyu Chen-Mayer, Danyal J. Turkoglu, Benjamin Riley, Emily Draeger, jerimy Polf
Prompt gamma activation analysis (PGAA) is a bulk elemental analysis technique using gamma rays emitted immediately following neutron capture. Spatial information about the composition within the sample could be obtained with PGAA in a time-consuming

Visualizing Structural Transformation and Guest Binding in a Flexible Metal-Organic Framework under High Pressure and Room Temperature

October 1, 2018
Author(s)
Hui Yang, Feng Guo, Prem Lama, Gaurav Verma, Wen-Yang Gao, Hui Wu, Leonard J. Barbour, Wei Zhou, Jian Zhang, Briana Aguila, Shengqian Ma
Understanding effect of gas molecules on the framework structures upon gas sorption in porous materials is highly desirable for the development of gas storage and separation technologies. However, this remains challenging for flexible metal-organic

ABC's of Conformity Assessment

September 30, 2018
Author(s)
Lisa J. Carnahan, Amy L. Phelps
The Standards Coordination Office periodically publishes information related to standards and conformity assessment as a service to producers and users of such systems – both in the public and private sector. This publication is designed to provide the

Conformity Assessment Considerations for Federal Agencies

September 30, 2018
Author(s)
Lisa J. Carnahan, Amy L. Phelps
The Standards Coordination Office periodically publishes information related to standards and conformity assessment as a service. This document provides those not fully familiar with the field of conformity assessment an introduction to the complexities in

Control of thermal expansion in a low-density framework modification of silicon

September 30, 2018
Author(s)
Beekman Mathew, James A. Kaduk, Winnie Wong-Ng, George S. Nolas
The low-density clathrate-II modification of silicon, Si136, contains two distinct cage-like voids large enough to accommodate various types of guest atoms which influence both the host structure and its properties. Although the linear coefficient of

Development of a Detection Algorithm for Kitchen Cooktop Ignition Prevention

September 30, 2018
Author(s)
Amy Mensch, Anthony Hamins, Kathryn Markell
A small number of previous studies focused on cooktop fire sources and considered multi-detector sensing of pre-ignition signatures in a kitchen environment. Johnsson conducted a series of experiments investigating the feasibility of distinguishing between

September 30, 2018
Author(s)
Bruce Arey, Edward Vicenzi, Rolf Sjoblom, Robert Koestler, Paula DePriest, Thomas Lam, David Peeler, John McCloy, Albert Kruger, Jamie Weaver
Borborg Hillfort is a vitrified hillfort located in the Husby-Långhundra parish in Uppland Sweden (Fig. 1A). The site dates to the Great Migration Period, around 740 ± 100 CE. [1]. Two types of glasses have been identified within the ramparts – one that is

Development of a new reversed-phase liquid chromatography and fluorescence method with multichannel selective wavelength detection for the analysis of benzo[a]pyrene and six of its isomers

September 28, 2018
Author(s)
Walter B. Wilson, Stephen A. Wise, Lane C. Sander
The baseline separation of benzo[a]pyrene in complex samples via reversed-phase liquid chromatography (RPLC) is particularly challenging due to the potential for interferences from other molecular mass 252 (MM, g/mol) polycyclic aromatic hydrocarbons (PAHs
