Compressed-Liquid Density Measurements of Methyl Oleate and Methyl Linoleate

September 30, 2011
Author(s)
Stephanie L. Outcalt
Compressed liquid densities of the fatty acid methyl esters methyl linoleate and methyl oleate have been measured with a vibrating-tube densimeter. The temperature and pressure range of the measured data is from 270 K to 470 K, and 0.5 MPa to 50 MPa. The

A STANDARD ANALYSIS APPROACH TO DETERMINE PRODUCT APPLICABILITY

August 31, 2011
Author(s)
Paul W. Witherell, Prabir Sarkar, Anantha Narayanan Narayanan, Jae H. Lee, Sudarsan Rachuri
Standards and regulations have become an important part of today’s society. Organizational and geographical dispersions of standards often create situations where manufacturers are forced to meet various standards for a product to reach expanded markets or

AN INFORMATION MODELING METHODOLOGY FOR STANDARDS

August 31, 2011
Author(s)
Anantha Narayanan Narayanan, Jae H. Lee, Paul W. Witherell, Prabir Sarkar, Sudarsan Rachuri
Standards are developed and introduced in the market to meet the needs of specific domains. Developed by experts within a particular domain, the modeling requirements necessary to represent the information associated with these standards are often not well

CHEMICAL INTERACTIONS OF THE Ba2YCu3O6+x SUPERCONDUCTOR WITH COATED CONDUCTOR BUFFER LAYERS

August 30, 2011
Author(s)
Winnie K. Wong-Ng, Zhi Yang, Guangyao Liu, Qingzhen Huang, Lawrence P. Cook, Shailee P. Diwanji, Christopher E. Lucas, Mi-Hye Jang, James A. Kaduk
Continued research on high Tc superconductors has led to the promise of a wide variety of industrial applications. To implement these applications, the availability of low-cost, long-length, and high-performance superconductor wire/tape and cable is

Development of a Seebeck Coefficient Standard Reference Material (SRM)™

August 1, 2011
Author(s)
Nathan Lowhorn, Winnie Wong-Ng, John Lu, Joshua B. Martin, Martin L. Green, John E. Bonevich, Evan L. Thomas, Neil Dilley, Jeff Sharp
We have successfully developed a Seebeck coefficient Standard Reference Material (SRM™), Bi2Te3, that is essential for interlaboratory data comparison and for instrument calibration. Certification measurements were performed using a differential steady

Comparison of Gas Velocity Measurements and CFD Predictions in the Exhaust Duct of a Stationary Source

July 13, 2011
Author(s)
Rodney A. Bryant, Olatunde B. Sanni, Elizabeth F. Moore, Robert P. Borthwick, Marco G. Fernandez, Iosif I. Shinder, Jiann C. Yang, Aaron N. Johnson
Two series of independent flow measurements were conducted for cross validation of flow velocity in the exhaust duct of the NIST Large Fire Laboratory. In the first series, two pressure measurement probe types, an S probe and a 3-D probe, were used to

Formation of stacking faults and their correlation with flux-pinning and critical current density for Sm-doped YBa2Cu3O7-x films

June 29, 2011
Author(s)
Winnie K. Wong-Ng, Sung H. Wee, Eliot D. Specht, Claudia Cantoni, Jonathan Zuegel, Victor Maroni, Guangyao Liu, Timothy J. Haugan, Amit Goyal
A correlation between flux-pinning characteristics and stacking faults (SFs) formed by Sm substitution on Y and Ba sites was found in Sm-doped YBCO films. It was confirmed that “223” type SFs, Y2Ba2Cu3Ox, composed of Y and O extra planes aligned parallel

APPLICATIONS OF HIGH-THROUGHPUT SCREENING TOOLS FOR THERMOELECTRIC MATERIALS

Author(s)
Winnie K. Wong-Ng, Howard L. Joress, Joshua B. Martin, Yonggao Y. Yan, Jihui Yang, Makoto Otani, Evan L. Thomas, Martin L. Green, Jason Hattrick-Simpers
The increased research and development on thermoelectric materials in recent years has been driven primarily by the need for improved efficiency in the global utilization of energy resources. To facilitate the search for new thermoelectric materials, we

Phase Equilibria, Crystal Chemistry and Thermoelectric Properties of Compounds in the Ca-Co-Zn-O System

June 21, 2011
Author(s)
Winnie K. Wong-Ng, Tana Luo, Wenjie Xie, Weihua Tang, James A. Kaduk, Qingzhen Huang, Yonggao Y. Yan, Soma Chattopadhyay
In the Ca-Co-Zn-O system, we have determined the tie-line relationships and the thermoelectric properties, solid solution limits, and structures of two low-dimensional cobaltite series, Ca3(Co, Zn)4O9 and Ca3(Co,Zn)2O6 at 885 C in air. In Ca3(Co,Zn)4O9

Parametric study of micropillar array solar cells

June 19, 2011
Author(s)
Heayoung Yoon, Yu A. Yuwen, Haoting Shen, Nikolas J. Podraza, Thomas E. Mallouk, Elizabeth C. Dickey, Joan A. Redwing, Christopher R. Wronski, Theresa S. Mayer
Micro/nano pillar arrays can be a promising architecture for high efficiency solar cells based on less expensive photovoltaic materials with short minority carrier diffusion lengths (Ln, p). To investigate design tradeoffs of the radial junction array
