A perspective on the origin of lubricity in petroleum distillate motor fuels

September 15, 2014
Author(s)
Peter Y. Hsieh, Thomas J. Bruno
Lubricity, or a substance's effect on friction and wear between two surfaces in relative motion, is affected by both chemical and physical mechanisms present at a sliding contact. The inherent lubricity of distillate motor fuels stems from surface-active

Evolution of electrochemical interfaces in solid oxide fuel cells (SOFC): a Ni and Zr resonant anomalous ultra-small-angle X-ray scattering studywith elemental and spatial resolution across the cell assembly

June 1, 2014
Author(s)
Andrew J. Allen, Jan Ilavsky, Pete R. Jemian, Artur Braun
Electrochemical interfaces are key to the direct conversion of fuels to electrical energy and lend energy converters like solid oxide fuel cells (SOFC) their functionality. Over extended operation at high temperatures, the microstructure of the underlying

Hydrogen Field Test Standard: Laboratory Performance

April 14, 2014
Author(s)
Jodie G. Pope, John D. Wright
NIST developed a prototype field test standard (FTS) that incorporates three test methods that could be used by state weights and measures inspectors to periodically test retail hydrogen dispensers, much as gasoline dispensers are tested today. The three

Engineering Plant Cell Walls: Tuning Lignin Monomer Composition for Deconstructable Biofuels Feedstocks or Resilient Biomaterials

February 27, 2014
Author(s)
Peter Ciesielski, Michael Resch, Barron Hewetson, Jason Killgore, Alexandra Curtin, Nick Anderson, Ann Chiaramonti Debay, Donna C. Hurley, Aric Sanders, Michael Himmel, Clint Chapple, Nathan Mosier, Bryon Donohoe
Advances in genetic manipulation of the biopolymers that compose plant cell walls will facilitate more efficient production of biofuels and chemicals from biomass and lead to specialized biomaterials with tailored properties. Here we investigate several
