Density and Speed of Sound Measurements of Four Bio-derived Fuels

September 13, 2012
Author(s)
Stephanie L. Outcalt, Tara J. Fortin
Compressed-liquid densities and ambient pressure densities and speeds of sound of four biomass-derived fuels have been measured. The compressed-liquid measurements were made from 270 K to 470 K, and 0.5 MPa to 50 MPa. The ambient pressure measurements were

FATIGUE CRACK GROWTH OF TWO X52 PIPELINE STEELS IN A PRESSURIZED HYDROGEN ENVIRONMENT

September 9, 2012
Author(s)
Andrew J. Slifka, Elizabeth S. Drexler, Neha N. Rustagi, Damian S. Lauria, Joseph D. McColskey, Robert L. Amaro
Fatigue crack growth tests were conducted on two API 5L X52 pipeline steel alloys. One alloy was from a new linepipe that was installed for hydrogen service in 2011. The other alloy was from a vintage pipe that first saw natural gas service in 1964

Signal Processing Techniques for Smart Grid: Scanning the Issue

Author(s)
Hamid Gharavi
This is an editorial article for a special issue on Smart Grid. The main emphasis of this issue is the technical challenges of the Smart Grid from a signal processing perspective. Therefore, the selected articles aim at articulating signal processing

Saturation molalities and standard molar enthalpies of solution of alpha-D-xylose(cr) in H2O(l); Standard molar enthalpies of solution of 1,4-beta-D-xylobiose(am), and 1,4-beta-D-xylotriose(am) in H2O(l)

The saturation molality of alpha-D-xylose(cr) in water was measured by using HPLC and is m(sat) = (8.43 ± 0.42) mol∙kg-1 at the temperature T = 298.15 K. It was also established that the anhydrous form of alpha-D-xylose(cr) is the crystalline form that is

Inelastic Neutron Scattering on Polymer Electrolytes for Lithium-Ion Batteries

May 7, 2012
Author(s)
Huagen H. Peng, Madhu Sudan Tyagi, Kirt A. Page, Christopher Soles
The relationship between ion transport and polymer dynamics is central to the pursuit of solid polymer electrolytes for lithium batteries. This understanding is critical to achieve solid polymer electrolyte systems of sufficiently high ion conductivities

Computational Seebeck Coefficient Measurement Simulations

May 2, 2012
Author(s)
Joshua B. Martin
We have employed finite element analysis to develop computational Seebeck coefficient metrology simulations. This approach enables a unique exploration of multiple probe arrangements and measurement techniques within the same temporal domain. To

Materials Challenges in Carbon Mitigation Technologies

April 24, 2012
Author(s)
Laura Espinal, Bryan D. Morreale
Thermochemical conversion of fossil fuels currently dominates the national and global energy portfolio, with the most notable being the stationary power production and transportation vehicles sectors. As global energy demand continues to increase

Carbon Storage Properties of OMS-2 Manganese Oxide

April 10, 2012
Author(s)
Lan (. Li, Eric J. Cockayne, Laura Espinal, Winnie K. Wong-Ng
Manganese oxide OMS-2 material, also known as alpha-MnO2, exhibits CO2 sorption hysteresis at pressures > 7 bar. Our experiments show that the hysteretic behavior strongly depends on time, temperature and pressure. To understand the atomic structures and
