Measurement, Standards, and Data Needs for CO2 Capture Materials: A Critical Review

October 21, 2013
Author(s)
Laura Espinal, Dianne L. Poster, Winnie K. Wong-Ng, Andrew J. Allen, Martin L. Green
The commercial deployment of cost-effective carbon capture technology is hindered partially by the lack of a proper suite of materials-related standards, data, and measurement methods, which would provide critical information for the systematic design of

Use Case Analysis for Standard Manufacturing Service Capability Model

September 12, 2013
Author(s)
Yunsu Lee, Boonserm Kulvatunyou, Marko Vujasinovic, Nenad Ivezic
To efficiently assemble manufacturing supply chains, manufacturers need to provide precise and easily accessible their manufacturing service capability (MSC) information described in the form of MSC descriptions. However, a number of challenges exist in

Congestion Due to Random Walk Routing

August 31, 2013
Author(s)
Vladimir V. Marbukh, Iraj Saniee, Onuttom Narayan
In this paper we derive an analytical expression for the mean load at each node of an arbitrary undirected graph for the uniform multicommodity flow problem under random walk routing. We show the mean load is linearly dependent on the nodal degree with a

Integration of Energy Information for Product Assembly and Logistics Processes

August 13, 2013
Author(s)
Shaw C. Feng, FNU Kumaraguru, Kincho H. Law, Kyeong Rim Ahn
This paper presents an on-going effort at NIST to model the energy performance in assembly and supply chain processes as a part of a larger sus-tainability improvement goal. Energy performance modeling comprises two dis-tinct metrics like energy

Intercomparison between optical and x-ray scatterometry measurements of FinFET structures

April 8, 2013
Author(s)
Paul Lemaillet, Thomas Germer, Regis J. Kline, Daniel Sunday, Chengqing C. Wang, Wen-Li Wu
In this paper, we present a comparison of profile measurements of vertical field effect transistor (FinFET) fin arrays by optical critical dimension (OCD) metrology and critical dimension small angle X-ray scattering (CD-SAXS) metrology. Spectroscopic

Using Attack Graphs in Forensic Examinations

January 16, 2013
Author(s)
Changwei Liu, Anoop Singhal, Duminda Wijesekera
Attack graphs are used to compute potential attack paths from a system configuration and known vulnerabilities of a system. Attack graphs can be used to eliminate known vulnerability sequences that can be eliminated to make attacks difficult and help

Electronic structure of Ba-Ga-Ge-Si Type I Clathrates: A Ge and Ga K-Edge Study

November 9, 2012
Author(s)
Winnie Wong-Ng, Azzam Mansour, Joshua Martin, George S. Nolas
XANES spectroscopy was successfully used to study changes in the density of unoccupied states for silicon substituted Ba8Ga16Ge30-xSix type I clathrates. Partial density of unoccupied states with p character is modified for both Ga and Ge upon Si

Nanoscale Fullerene Compression of an Yttrium Carbide Cluster

April 13, 2012
Author(s)
Jianyuan Zhang, Fuhrer Tim, Wujun Fu, Jiechao Ge, Dan Bearden, Jerry Dallas, Duchamp James, Kenneth Walker, Hunter Champion, Hugo Azurmendi, Kim Harich, Harry C. Dorn
The encapsulation of clusters (or small molecules) in spheroidal fullerene cages provides a unique isolated environment that is important in describing their shape, dynamics, and physical properties. For the case of yttrium carbide clusters, we find that

Modeling Cement Hydration Kinetics Using the Equivalent Age Concept

March 29, 2012
Author(s)
Xueyu Pang, Dale P. Bentz, Christian Meyer
In this study the hydration kinetics of four different types of cements during early ages were investigated by both chemical shrinkage and isothermal calorimetry tests. Chemical shrinkage tests were performed at both different temperatures and pressures

MBE Standardization and Validation

July 6, 2011
Author(s)
Joshua Lubell, Nathan W. Hartman, Doug Cheney
3D Model-Based Engineering (MBE) is an approach to product design, manufacturing, and support where a digital three-dimensional representation of the product serves as the normative source for information communicated throughout the product’s lifecycle and

An IEEE 1451.5-802.11 Standard-based Wireless Sensor Network with Embedded WTIM

May 12, 2011
Author(s)
Eugene Song, Kang B. Lee, Steven E. Fick, Alkan Donmez
This paper introduces a reference implementation of the Institute of Electrical and Electronics Engineers (IEEE) 1451.5-802.11 standard-based wireless sensor network (WSN) developed at the National Institute of Standards and Technology (NIST). The WSN

Onset of Morphological Instability in Two Binary Liquid Layers

April 1, 2011
Author(s)
Geoffrey B. McFadden, Sam R. Coriell, Aaron Lott
We consider the linear stability of a horizontal fluid bilayer subject to vertical heating. The two layers consist of a binary fluid that has undergone a phase transition, resulting in a horizontal interphase boundary between two phases with different

Onset of Convection in Binary Liquid Layers

March 24, 2010
Author(s)
Geoffrey B. McFadden, Sam R. Coriell, Aaron Lott
We perform linear stability calculations for horizontal bilayers of a two-component fluid that can undergo a phase transformation, taking into account both buoyancy effects and thermocapillary effects in the presence of a vertical temperature gradient

Comparison of Electronics Products Standards for Sustainability

March 1, 2010
Author(s)
Gaurav Ameta, Prabir Sarkar
This paper focuses on electronics product standards in relation to sustainability. Sustainability can be viewed as the ability of the current generation to meet its own need while protecting the environment so that the future generations can also meet

Bending of a Bimetallic Beam due to the Kirkendall Effect

January 1, 2010
Author(s)
William J. Boettinger, Geoffrey B. McFadden
The time dependent bending of single phase and two phase bimetal strips due to interdiffusion is computed. The model couples simple beam theory and diffusion, the bending being due to the creation and /annihilation of vacancies necessitated by unequal

HYDRATED PHASES IN BLENDED CEMENTITIOUS SYSTEMS FOR NUCLEAR INFRASTRUCTURE

October 15, 2009
Author(s)
Kenneth A. Snyder, Paul E. Stutzman, Jacob Philip, David W. Esh
The hydration products of varying proportions of portland cement, fly ash, ground granulated blast furnace slag, and silica fume in blended systems were identified and quantified. The proportion of portland cement varied from 100 % down to 10 %. The
