Towards Demand Response Measurement and Verification Standards

May 1, 2013
Author(s)
David G. Holmberg, David Hardin, Ed Koch
The value and impact of demand response (DR) at grid-scale depends upon the widespread and active participation of a diverse customer base. The level of participation by customers is impacted by financial compensation and return-on-investment. The role of

Advanced Distillation Curve Analysis of Marine Diesel Fuel

January 17, 2013
Author(s)
Peter Y. Hsieh, Kathryn R. Abel, Thomas J. Bruno
Ocean-going ships burn heavy fuel oil. The combustion of heavy fuel oil in marine diesel engines emits nitrogen oxides, sulfur oxides, and particulates into the air. Growing public concern over air quality has led to increased scrutiny of heavy fuel oil as

The BIOREMA project part 2: International interlaboratory comparison for biodiesel test methods

January 4, 2013
Author(s)
Michele M. Schantz, Manuela Ulberth-Buchgraber, Monica Potalivo, Andrea Held, Annaratia Baldan, Adriaan van der Veen, Hugo Ent, Valnei Cunha, Romeu Daroda, Ruth Hearn, Richard Brown, Paul Brewer, Brian E. Lang
The results of an interlaboratory comparison, using various measurement methods to carry out biodiesel testing, are presented, and the findings discussed. The interlaboratory comparison was organised within the framework of an EU funded project called

Phase Diagram and Crystal Chemistry of the La-Ca-Co-O System

December 27, 2012
Author(s)
Winnie K. Wong-Ng, William J. Laws, Yonggao Y. Yan
The phase diagram of the La-Ca-Co-O system at 885 °C in air has been determined. The system consists of two materials that have interesting thermoelectric properties, namely, the misfit layered thermoelectric oxide solid solution, (Ca, La)3Co4O9, and

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

On Distributed Energy Routing Protocols in the Smart Grid

November 5, 2012
Author(s)
Jie Lin, Guobin Xu, David W. Griffith, Xinyu Yang, Wei Yu
The Smart Grid is a new type of power grid that will provide reliable, secure, and efficient energy transmission and distribution. It promises to integrate distributed energy resources with conventional generation plants, and intelligently transmit energy

High temperature thermoelectric properties of p-type skutterudites BaxYbyCo4-zFezSb12

October 23, 2012
Author(s)
Yongkwan Dong, Pooja Puneet, Terry M. Tritt, Joshua Martin, George S. Nolas
Several polycrystalline p-type skutterudites with compositions BaxYbyCo4-zFezSb12, with varied filler concentrations x and y, and z = 1 to 2, have been synthesized by first reacting the constituents and subsequent solid state annealing, followed by

Bi2Te3 and Bi2Te3-xSx FOR THERMOELECTRIC APPLICATIONS

October 15, 2012
Author(s)
Winnie K. Wong-Ng, N D. Lowhorn, Joshua B. Martin, Peter Zavalij, Howard Joress, Qingzhen Huang, Yonggao Y. Yan, Azzam Mansour, Evans L. Thomas, Jihui Yang, Martin L. Green
The increased interest in research and development on thermoelectric materials is partly due to the need for improved efficiency in the global utilization of energy resources. Historically, Bi2Te3 occupies an important position in the thermoelectric

Thermal Decomposition of 1-Pentyl Radicals at High Pressures and Temperatures

September 27, 2012
Author(s)
Andrea Comandini, Iftikhar A. Awan, Jeffrey A. Manion
Complementary shock-tube studies at the National Institute of Standards and Technology (NIST) and the University of Illinois at Chicago (UIC) have been used to examine the decomposition reactions of the 1-pentyl radical at temperatures of 833 K to 1130 K
