Materials Design for Biomechanical Layer Structures

February 19, 2017
Author(s)
Brian R. Lawn, Antonia Pajares, P Miranda, Y N. Deng
A survey of recent advances in the analysis of ceramic-based layer structures for biomechanial applications is presented. Data on model layer systems, facilitating development of explicit fracture mechanics relations for predicting critical loads to

MatML Editor: Technical Documentation

February 19, 2017
Author(s)
J Bakoczy, E F. Begley
This manuscript contains the technical documentation for the MatML Editor, an enabling technology intended to support widespread adoption of the language. The MatML Editor is a user-friendly, browser-based, form-driven application.

MatML Editor: User Documentation

February 19, 2017
Author(s)
J Bakoczy, E F. Begley
This manuscript contains the end-user documentation for the MatML Editor, an enabling technology intended to support widespread adoption of the language. The MatML Editor is a user-friendly, browser-based, form-driven application.

Measurement Methods for Materials Properties: Elasticity

February 19, 2017
Author(s)
Sheldon M. Wiederhorn, Richard J. Fields
Elastic constants must be obtained by experiment methods. Materials are too complicated and theory of solids insufficiently sophisticated to obtain accurate theoretic determinations of elastic constants. Usually, simple static mechanical tests are used to

Measurements of the Photolytic Breakdown of Decabromodiphenyl Ether in Plastics

February 19, 2017
Author(s)
Marc R. Nyden, Rick D. Davis, Christopher C. White, H M. Stapleton, Nathan G. Dodder
In this talk, we report the product distributions and decomposition rates of DecaBDE when it is incapsulated in a common plastic, high impact polystyrene, and irradiated under controlled conditions using a calibrated source. The objective is to gain

Measuring the Affordability of Residential Building Innovations

February 19, 2017
Author(s)
C J. Leng
Innovations in residential construction have faced many barriers to adoption. One critical barrier is the absence of metrics that allow homeowners, home builders, and homebuyers to compare the cost effectiveness of adopting these new technologies in owner

Mechanical Reliability and Life Prediction for Brittle Materials

February 19, 2017
Author(s)
Grady S. White, Lin-Sien H. Lum, Stephen W. Freiman
This chapter is intended to provide the reader with a general understanding of why brittle materials fail in a time-dependent manner in service and how to estimate the lifetimes that can be expected for such materials. In addition, we describe procedures

Microgravity Superagglomerates Produced by Silane and Acetylene

February 19, 2017
Author(s)
Matthew Bundy, George Mulholland, Samuel Manzello, Jiann C. Yang, J H. Scott
A study of acetylene and silane diffusion flames was performed in normal gravity (1-g) and microgravity ([mu]-g) to determine the evolution of soot and silica agglomerates. The objective of this study was to understand the process of gas phase

Mini-Matt Flammability and Its Relation to Full-Scale Mattress Flammability

February 19, 2017
Author(s)
Thomas J. Ohlemiller, Roy A. McLane
Mini-mattresses of a size used for commercial display, were subjected to a pair of NIST-developed gas burners and the resulting heat release behavior was recorded. Peak heat release rate and time to peak for five sample designs were compared to the full

Model for Adhesion-Based Energy Dissipation During Friction

February 19, 2017
Author(s)
Michael Nosonovsky, Stephen M. Hsu
Adhesion plays a significant role in Nanoscale interfacial friction for basically non-adhesive surfaces (no chemical bonding). The adhesion forces are composed of van der Waals forces and the contact force from surface contact. The van der Waals forces are

Modeling Building Access Control with BACnet

February 19, 2017
Author(s)
Stephen J. Treado, S Cook, Banty Jain, Michael Galler
This report describes a typical implementation of a building access control system integrated with other portions of a building automation system, using some of the newly developed features of BACnet. This functionality has been implemented in the NIST

Modeling, Measurement, and Standards for Wafer Inspection

February 19, 2017
Author(s)
George Mulholland, Thomas A. Germer, J C. Stover
The major technical issues regarding the calibration of Surface Scanning Inspection Systems (SSIS) are presented including descriptions of the salient features of SSISs and the deposition system using the differential mobility analyzer. The role of the

Moment Method for Obtaining Particle Size Measures of Test Smokes

February 19, 2017
Author(s)
Thomas Cleary, D W. Weinert, George Mulholland
The number concentration, ionization chamber output, and mass concentration were recorded continuously for five different test smokes generated in the fire emulator/detector evaluator. The number and the mass concentrations are direct measures of the

Morphology, Structure, and Nucleation of Out-of-Phase Boundaries (OPBs) in Epitaxial Films of Layered Complex Oxides

February 19, 2017
Author(s)
M A. Zurbuchen, W Tian, X Q. Pan, D Fong, S K. Streiffer, M E. Hawley, J Lettieri, Y Jia, Shengqian Ma, S J. Fulk, D J. Comstock, S Knapp, A H. Carim, D G. Schlom
Out-of-phase boundaries (OPBs) are translation boundary defects characterized by a misregistry of a fraction of a unit cell dimension in neighboring regions of a crystal. Although rarely observed in the bulk, they are common in epitaxial films of layered

Multiscale Roughness and Stability of Superhydrophobic Biomimetic Interfaces

February 19, 2017
Author(s)
Michael Nosonovsky
Stability of a composite interface (CI) of roughness-induced superhydrophobic surfaces is studied. In order to have high contact angle and low contact angle hysteresis, superhydrophobic surfaces should be able to form a CI with air pockets in the valleys
