Simulations of Microstructural Evolution: Anisotropic Growth and Coarsening

February 19, 2017
Author(s)
A R. Roosen, W Carter
Two-dimensional calculations of anisotropic growth and coarsening are illustrated. This model is intended to simulate the development of microstructure in materials like Silicon Nitride. The model is comprised of an ensemble of polygonal particles with

Smoke Toxicity Data for Fire Hazard and Risk Assessment of Cable Products

February 19, 2017
Author(s)
Richard Gann, Richard D. Peacock, Jason D. Averill, Marc R. Nyden
This report presents the methodology for and results from a series of room-scale fire tests to produce data on the yields of toxic products in both pre-flashover and post-flashover fires. Trays of common household electric cable burned in a room with a

Spontaneous Ejecta From [Beta]-Eucryptite Composites

February 19, 2017
Author(s)
Ivar E. Reimanis, C Seick, K Fitzpatrick, Lin-Sien H. Lum, S Landin
Polycrystalline ceramic composites, comprised of primarily b-eucryptite (LiAlSiO4) and lithium aluminate (LiAl5O8) crystals, with a near-zero coefficient of thermal expansion were examined with indentation experiments. A unique behavior is reported

Standardized Cost Structure for the Environmental Industry

February 19, 2017
Author(s)
Harold E. Marshall, Bryan Skokan, Dan Melamed, Karen Guevara, George Bierman
The underlying key to developing successful estimates, tracking projects costs, and utilizing historical project cost information is the development of standardized and well defined hierarchical listing of cost categories. Committees within OECD/NEA and

Standards for Biomaterials

February 19, 2017
Author(s)
Stephen W. Freiman, John A. Tesk
This paper is a summary of a workshop session during the Workshop on Biomedical Materials and Devices, held June 13-14, 2001. The workshop is part of a series of workshops and topical meetings organized by NIST in the area of biomedical technology. The

Structural Analysis of a High-Rise Composite Frame Exposed to Fire

February 19, 2017
Author(s)
Dat Duthinh, Kuldeep Prasad
This paper presents a simplified, planar analysis of World Trade Center Tower 1 (WTC1), starting from a computer simulation of the fire using computational fluid dynamics, and progressing through a thermal and a structural analysis of the damaged structure

Structural Calcium (Trypsin, Subtilisin)

February 19, 2017
Author(s)
G L. Gilliland, A Teplyakov
There are about 40 families of serine proteases defined by amino acid sequence similarities that can be further grouped into 7 clans on the basis of their tertiary structure and the order of the catalytic triad. 1 Members of clans SA and SB are

Structural Ceramics Database Update (April 2003)

February 19, 2017
Author(s)
R G. Munro, C P. Sturrock
An update of the NIST Standard Reference Database Number 30, the Structural Ceramics Database, has been completed. This update, designated SCD Update (April 2003), increases the number of source entries by 100 citations and increases the total number of

Subsolidus Phase Equiibria of the 2223 (Bi:Sr:Ca:Cu) Phase at 840 C to 850 C in Air

February 19, 2017
Author(s)
Winnie Wong-Ng, Lawrence P. Cook, F Jiang, L Swartzendruber, P Sastry
The subsolidus phase equilibria involving the Bi-2223(Bi 2Sr 1.9Ca 2.1Cu 3O 10+x) phase in the Bi-Sr-Ca-Cu-O system (BSCCO) were investigated at 840-850The subsolidus phase equilibria involving the Bi-2223(Bi2Sr1.9Ca2.1Cu3O10+x) phase in the Bi-Sr-Ca-Cu-O

Subsolidus Phase Relationships of the BaO-R 2 O 3 -CuO z (R=Tm and Yb) Systems Under Carbonate-Free Conditions at p o2 = 100 Pa, and T = 750 Degree Celcius and 810 Degree Celcius

February 19, 2017
Author(s)
Winnie Wong-Ng, Zhi Yang, Lawrence P. Cook
For applications of phase equilibria to coated conductor processing, phase diagrams constructed under carbonate-free conditions should be employed. Using special apparatus and a procedure for preparing carbonate-free precursors based on BaO, phase diagrams

Surface and Interface Properties of Crosslinked Amine-Cured Epoxies

February 19, 2017
Author(s)
Tinh Nguyen, G Xiaohong, M Giraud, Mark R. VanLandingham, Jonathan W. Martin
The surface and film/substrate interface properties of a coating system have a strong influence on its adhesion and durability. However, both the surface and interface chemical composition and microstructure of a crosslinked coating applied to a substrate

Survey of the State-of-the-Art for Ocean Wave Energy Conversion Systems

February 19, 2017
Author(s)
Kathryn Butler, Marc R. Nyden, William G. Rippey
It is possible to generate electrical energy from the motion of water due to ocean tides and waves. Oceans are a much more ubiquitous source of flowing water than river gorges, and the ability to efficiently harness this energy could potentially solve many
