How Standards Help Bring New Materials to the Market

February 19, 2017
Author(s)
Stephen W. Freiman, George D. Quinn
This paper attempts to describe the importance of standards in helping to bring new materials to the market place. Using ceramic materials as an example, the different ways that standards can be important in the materials development process are outlined

ICSD Accessibility in Support of Materials Research and Design

February 19, 2017
Author(s)
Vicky L. Karen, A J. Belsky
The materials community in both science and industry use crystallographic data models on a daily basis to visualize, explain, and predict the behavior of chemicals and materials. Access to reliable information on the structure of crystalline materials

Ignition of Mulch by Firebrands in Wildland/Urban Interface (WUI) Fires

February 19, 2017
Author(s)
Samuel Manzello, John R. Shields, Thomas Cleary, Jiann C. Yang
Firebrands or embers are produced as trees and structures burn in wildland/urban interface (WUI) fires. Hot firebrands ultimately come to rest and may ignite fuels far removed from the fire, resulting in fire spread. It is believed that firebrand showers

Imaging Optics and CCD Camera Characterization for Metrology

February 19, 2017
Author(s)
S Fox, Edward A. Kornegay, Richard M. Silver
Optical semiconductor characterization and metrology rely heavily on digital camera imaging and its associated optical imaging systems. This work characterizes the performance of a widely used, commercially available camera and compares its performance to

Improving a Web-Based Firm Level R&D Survey

February 19, 2017
Author(s)
J Powell
The Advanced Technology Program (ATP) is a federal science and technology program whose mission is to accelerate the development of innovative technologies for broad national benefit through partnerships with the private sector. To help correct certain

Improving the Interface Between Thermal and Structural Finite-Element Analyses

February 19, 2017
Author(s)
Dat Duthinh, Abed M. Khaskia
One of the recommendations of the National Construction Safety Team for the Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1, 2005) is to enhance the capability of available computational software to predict

In Situ Burning of Oil Spills: Resource Collection

February 19, 2017
Author(s)
William Walton
The Minerals Management Service (MMS), U.S. Department of Interior, is designated as the lead agency for in situ burn research in the Oil Pollution Research and Technology Plan prepared under the authority of Title VII of the Oil Pollution Act of 1990 (OPA

Influence of Particle Size on DCPD Hydrolysis and Setting Properties of TTCP/DCPD Cement

February 19, 2017
Author(s)
Limin Sun, Laurence C. Chow, Shozo Takagi, Elena F. Burguera, Stanislav Frukhtbeyn
This study investigated the effects of particle size on the hydrolysis reaction of DCPD at pH 7 and 37 C and on the setting properties of a TTCP/DCPD cement. The kinetics of the hydrolysis reaction was controlled by a nucleation and growth mechanism

Instability of Adhesion Force Between Rough Surfaces

February 19, 2017
Author(s)
Michael Nosonovsky, Seung H. Yang, Huan Zhang
Adhesion force has a significant effect upon the contact of rough surfaces with nanoscale asperities. The dominant component of the adhesion force is the capillary force caused by condensed water menisci. The capillary force depends upon the meniscus shape

Interfacial Dewetting in Silicon Nitride Containing Aligned Grains

February 19, 2017
Author(s)
B Hockey, D S. Park, H D. Kim, S W. Lee
It is generally believed that liquid phase sintering of silicon nitride invariably results in a continuous intergranular phase such that individual grains are separated by a glassy interphase, typically as thin as I nm. To the contrary, results presented

International Standards for Service Life Planning of Buildings

February 19, 2017
Author(s)
G J. Frohnsdorff, C Sjostrom, G Soronis
ISO Technical Committee TC 59, Building Construction, is an international standards committee dealing with general rules for performance requirements for buildings, SC 14, Design Life, is the subcommittee of TC 59 that deals with standardization of the

Investigation of Unresolved Issues From ATL Temperature Control Module

February 19, 2017
Author(s)
Stephen J. Treado
A series of measurements and performance evaluations has been conducted in the Temperature Control Module (TCM) for three control system vendors in order to demonstrate their ability to meet the high accuracy temperature control specification for the

Ionic Liquids as Compatibilizers for the Preparation of Biopolymer Nanocomposites: Characterization Using Laser Scanning Confocal Microscopy

February 19, 2017
Author(s)
Jeffrey W. Gilman, P H. Maupin, Mauro Zammarano, Paul C. Trulove, D M. Fox, H DeLong, Ph Dubois, M Murariu
The process of dispersing ionic liquid modified montmorillonite in polylactide (PLA) using a twin-screw micro-compounder under different melt-compounding parameters was monitored using laser scanning confocal microscopy (LSCM). In addition the PLA-MMT

Kinetic Modeling of Heptane Combustion and PAH Formation

February 19, 2017
Author(s)
Valeri I. Babushok, Wing Tsang
Kinetics of heptane combustion was studied through numerical modeling. High temperature kinetic model of heptane combustion was constructed. The model includes four main blocks of reactions: C1-C2 chemistry, which is based on Grimech-3.0 model; block of C3

Laser Stabilization

February 19, 2017
Author(s)
John L. Hall, Jun Ye, M S. Taubman
It becomes clear that there are many interlinking considerations involved in the design of-laser stabilization systems, and it is difficult to present a full description in an article such as this. Still it is hoped that the reader will see some avenues to

Lateral Force Microscope Calibration Using a Modified AFM Cantilever

February 19, 2017
Author(s)
Mark Reitsma
A proof-of-concept study is presented for a new force transducer and associated calibration method that provides a path for quantitative friction measurements using a Lateral Force Microscope. The transducer design is an Atomic Force Microscope (AFM)
