Presentation for the 2007 University Scholars Day at the University of North Texas. This presentation discusses research on characterizing the changes in tissue morphology occurring in the emu ductus arteriosus during hatching and what role apoptosis plays during the process of the ductus closure.

Presentation by Dr. Dan Arvizu of NREL given at the Colorado New Energy Summit held March 24, 2007 in Denver, Colorado.

Presentation outlining the progress of DOE's Controlled Hydrogen Fleet and Infrastructure Demonstration and Validation Project, prepared for the 2006 National Hydrogen Association Meeting.

Cr alloys containing 0-30 weight % W were investigated for their high temperature strength and oxidation resistance. These experimental alloys are intended for use in elevated temperature applications. Alloys were melted in a water-cooled, copper-hearth arc furnace. Microstructure of the alloys was studied using X-ray diffraction, scanning electron microscopy, and light microscopy. Meyer and Vickers hardness tests were utilized for measuring room temperature strength. A hot hardness tester with a spherical ruby indenter was used to study the strength of these materials between 800ºC and 1200ºC. A parabolic relationship was observed between load and indent size at all temperatures. On the other hand, decrease in hardness of the alloys with temperature was linear up to 1200ºC.

This research hypotheses is: (1) Indigenous microorganisms in the shallow aquifer at the FRC have the capability to reduce U(VI) and Tc(VII) but rates are limited by--Scarce electron donor, Low pH and potentially toxic metals, and High nitrate. (2) U(VI) and Tc(VII) reduction rates can be increased by--Successive donor additions, Raising pH to precipitate toxic metals, and Adding humics to complex toxic metals and serve as electron shuttles.

The primary objective of this report is to evaluate the rates and mechanisms of U(VI) reduction by microbial populations.

This presentation provides the results, as of Spring 2007, for the fuel cell vehicle learning demonstration conducted by the National Renewable Energy Laboratory.

The conclusions of this presentation are: (1) Fuel cells operating on bio-gas offer a pathway to renewable electricity generation; (2) With federal incentives of $3,500/kW or 30% of the project costs, reasonable payback periods of less than five years can be achieved; (3) Tri-generation of electricity, heat, and hydrogen offers an alternative route to solving the H{sub 2} infrastructure problem facing fuel cell vehicle deployment; and (4) DOE will be promoting bio-gas fuel cells in the future under its Market Transformation Programs.
