LOW TEMPERATURE CATHODE SUPPORTED ELECTROLYTES (open access)

LOW TEMPERATURE CATHODE SUPPORTED ELECTROLYTES

This report represents a summary of the work carried out on this project which started October 1999 and ended March 2003. A list of the publications resulting from the work are contained in Appendix A. The most significant achievements are: (1) Dense nanocrystalline zirconia and ceria films were obtained at temperatures < 400 C. (2) Nanocrystalline films of both ceria and zirconia were characterized. (3) We showed that under anodic conditions 0.5 to 1 micron thick nanocrystalline films of Sc doped zirconia have sufficient electronic conductivity to prevent them from being useful as an electrolyte. (4) We have developed a process by which dense 0.5 to 5 micron thick dense films of either YSZ or ceria can be deposited on sintered porous substrates which serve as either the cathode or anode at temperatures as low as 400 C. (5) The program has provided the research to produce two PhD thesis for students, one is now working in the solid oxide fuel cell field. (6) The results of the research have resulted in 69 papers published, 3 papers submitted or being prepared for publication, 50 oral presentations and 3 patent disclosures.

Field Demonstration of Carbon Dioxide Miscible Flooding in the Lansing-Kansas City Formation, Central Kansas Progress Report (open access)

Field Demonstration of Carbon Dioxide Miscible Flooding in the Lansing-Kansas City Formation, Central Kansas Progress Report

Progress is reported for the period from January 1, 2003 to March 31, 2003. A water supply well was permitted, drilled, and completed in the shallow, fresh-water, Dakota Sandstone. The pumphouse has been put in place and the long-term injection equipment is being set-up. Although the short-term injectivity test was cut short by power failure following an ice storm, results indicate the well exhibits sufficient injectivity to proceed with the long-term injectivity test, which will start in the beginning of the second quarter. The CO2 Project No.10 and No.12 wells were reworked and the Lansing-Kansas City (LKC) ''C'' interval in both wells isolated. The CO2 Project No.16 well was drilled deeper, cored in the LKC ''C'' and ''G'' zones, and cased to the ''C'' zone and will be perforated and stimulated in the beginning of second quarter. Initial wireline log analysis and examination of the core indicate that the porosity of the ''C'' zone in this location may be lower than in other parts of the pattern by 3-5 porosity units. Log analysis indicates water saturations are near 60% consistent with predicted residual oil saturation to waterflood modeling. Lower porosities may indicate lower permeability may also be present. Core analysis …

High Resolution Prediction of Gas Injection Process Performance for Heterogeneous Reservoirs Quarterly Report (open access)

High Resolution Prediction of Gas Injection Process Performance for Heterogeneous Reservoirs Quarterly Report

This report outlines progress in the second quarter of the third year of the DOE project ''High Resolution Prediction of Gas Injection Process Performance for Heterogeneous Reservoirs''. This report presents results of an investigation of the effects of variation in interfacial tension (IFT) on three-phase relative permeability. We report experimental results that demonstrate the effect of low IFT between two of three phases on the three-phase relative permeabilities. In order to create three-phase systems, in which IFT can be controlled systematically, we employed analog liquids composing of hexadecane, n-butanol, isopropanol, and water. Phase composition, phase density and viscosity, and IFT of three-phase system were measured and are reported here. We present three-phase relative permeabilities determined from recovery and pressure drop data using the Johnson-Bossler-Naumann (JBN) method. The phase saturations were obtained from recovery data by the Welge method. The experimental results indicate that the wetting phase relative permeability was not affected by IFT variation whereas the other two-phase relative permeabilities were clearly affected. As IFT decreases the ''oil'' and ''gas'' phases become more mobile at the same phase saturations.

Intermodal Rail Freight: A Role for Federal Funding? (open access)

Intermodal Rail Freight: A Role for Federal Funding?

As Congress considers reauthorization of federal highway and transit programs and funding, currently provided by the Transportation Equity Act for the 21st Century (TEA-21, P.L. 105-178), one issue being discussed is the role of freight rail in the nation’s transportation system. Economic and trade growth, along with growing congestion on certain parts of the nation’s interstate highway system, has focused attention on the ability of the railroads to divert more truck traffic to rail. However, the railroads are currently operating at close to capacity. Many rail analysts question whether the railroads are making sufficient profit to add adequate capacity to their intermodal network. This raises the issue of whether the government could or should assist the railroads in expanding the capacity of their infrastructure. And if so, how a funding program could be arranged.

Novel EUV Mask Blank Defect Repair Developments (open access)

Novel EUV Mask Blank Defect Repair Developments

The development of defect-free reticle blanks is an important challenge facing the commercialization of extreme ultraviolet lithography (EUVL). The basis of EUVL reticles are mask blanks consisting of a substrate and a reflective Mo/Si multilayer. Defects on the substrate or defects introduced during multilayer deposition can result in critical phase and amplitude defects. Amplitude- or phase-defect repair techniques are being developed with the goal to repair many of these defects. In this report, we discuss progress in two areas of defect repair: (1) We discuss the effect of the residual reflectance variation over the repair zone after amplitude-defect repair on the process window. This allows the determination of the maximum tolerable residual damage induced by amplitude defect repair. (2) We further performed a quantitative assessment of the yield improvement due to defect repair. We found that amplitude- and phase-defect repair have the potential to significantly improve mask blank yield. Our calculations further show that yield can be maximized by increasing the number of Mo/Si bilayers.

Innovative MIOR Process Utilizing Indigenous Reservoir Constituents (open access)

Innovative MIOR Process Utilizing Indigenous Reservoir Constituents

This research program is directed at improving the knowledge of reservoir ecology and developing practical microbial solutions for improving oil production. The goal is to identify indigenous microbial populations which can produce beneficial metabolic products and develop a methodology to stimulate those select microbes with nutrient amendments to increase oil recovery. This microbial technology has the capability of producing multiple oil-releasing agents. Experimental laboratory work is underway. Microbial cultures have been isolated from produced water samples. Comparative laboratory studies demonstrating in situ production of microbial products as oil recovery agents were conducted in sand packs with natural field waters with cultures and conditions representative of oil reservoirs. Field pilot studies are underway.

C1 Chemistry for the Production of Ultra-Clean Liquid Transportation Fuels and Hydrogen

Faculty and students from five universities--the University of Kentucky, University of Pittsburgh, University of Utah, West Virginia University, and Auburn University--are collaborating in a research program to develop C1 chemistry processes to produce ultra-clean liquid transportation fuels and hydrogen, the zero-emissions transportation fuel of the future. The feedstocks contain one carbon atom per molecular unit. They include synthesis gas (syngas), a mixture of carbon monoxide and hydrogen produced by coal gasification or reforming of natural gas, methane, methanol, carbon dioxide, and carbon monoxide. An important objective is to develop C1 technology for the production of transportation fuel from domestically plentiful resources such as coal, coalbed methane, and natural gas. An Industrial Advisory Board with representatives from Chevron-Texaco, Eastman Chemical, Conoco-Phillips, Energy International, the Department of Defense, and Tier Associates provides guidance on the practicality of the research. The current report presents results obtained in this research program during the first six months of the subject contract (DE-FC26-02NT-4159), from October 1, 2002 through March 31, 2003.

Modeling of Glass Making Processes for Improved Efficiency (open access)

Modeling of Glass Making Processes for Improved Efficiency

The overall goal of this project was to develop a high-temperature melt properties database with sufficient reliability to allow mathematical modeling of glass melting and forming processes for improved product quality, improved efficiency and lessened environmental impact. It was initiated by the United States glass industry through the NSF Industry/University Center for Glass Research (CGR) at Alfred University [1]. Because of their important commercial value, six different types/families of glass were studied: container, float, fiberglass (E- and wool-types), low-expansion borosilicate, and color TV panel glasses. CGR member companies supplied production-quality glass from all six families upon which we measured, as a function of temperature in the molten state, density, surface tension, viscosity, electrical resistivity, infrared transmittance (to determine high temperature radiative conductivity), non-Newtonian flow behavior, and oxygen partial pres sure. With CGR cost sharing, we also studied gas solubility and diffusivity in each of these glasses. Because knowledge of the compositional dependencies of melt viscosity and electrical resistivity are extremely important for glass melting furnace design and operation, these properties were studied more fully. Composition variations were statistically designed for all six types/families of glass. About 140 different glasses were then melted on a laboratory scale and their viscosity and …
