A Methodology to Evaluate Wireless Technologies for the Smart Grid

October 4, 2010
Author(s)
Michael R. Souryal, Camillo A. Gentile, David W. Griffith, David E. Cypher, Nada T. Golmie
This paper presents a methodology for assessing the suitability of various wireless technologies for meeting the communication requirements of Smart Grid applications. It describes an approach for translating application requirements to link traffic

Phase Equilibria of the Ba-Sm-Y-Cu-O System for Coated Conductor Applications

September 8, 2010
Author(s)
Winnie K. Wong-Ng, Guangyao Liu, Zhi Yang, James A. Kaduk, Lawrence P. Cook
The complex phase relationships near the BaO-poor region of the quaternary Ba-Sm-Y-Cu-O oxide system prepared in pure air (pO2 = 22 kPa, 950 ºC) and in 0.1% O2 (pO2=100 Pa, 810 ºC) have been determined. This investigation also included the subsolidus

NIST COORDINATION OF SMART GRID INTEROPERABILITY STANDARDS

August 9, 2010
Author(s)
David A. Wollman, Gerald FitzPatrick, Paul A. Boynton, Thomas L. Nelson
The National Institute of Standards and Technology has efforts underway to accelerate the development of interoperability standards to support the future modernized "Smart Grid" electric grid or energy delivery network characterized by a two-way flow of

Application of Microwave Scanning Probes to Photovoltaic Materials

June 20, 2010
Author(s)
Kristine A. Bertness, John B. Schlager, Norman A. Sanford, Atif A. Imtiaz, Thomas M. Wallis, Joel C. Weber, Pavel Kabos, Lorelle M. Mansfield
We demonstrate that near field scanning microwave microscopy (NSMM) can be used to detect photoresponse in photovoltaic materials with potential for submicrometer resolution. In this approach, a radio-frequency scanning tunneling microscopy (RF-STM) tip is

Space charge limited current effects in silicon at high injection levels

June 20, 2010
Author(s)
Ari D. Feldman, Richard K. Ahrenkiel
The space charge limited current (SCLC) effect will be analyzed in undoped crystalline silicon wafers at high injection levels. Space charge limited currents develop when the electric field from the injected carriers exceeds that of the background doping
