Assessing the Performance of 5mm White LED Light Sources forDeveloping-Country Applications (open access)

Assessing the Performance of 5mm White LED Light Sources forDeveloping-Country Applications

Some white light-emitting diode (LED) light sources haverecently attained levels of efficiency and cost that allow them tocompete with fluorescent lighting for off-grid applications in thedeveloping world. Additional attributes (optics, size, ruggedness, andservice life) make them potentially superior products. Enormousreductions in energy use and greenhouse-gas emissions are thus possible,and system costs can be much lower given the ability to downsize thecharging and energy storage components compared to a fluorescentstrategy. However, there is a high risk of "market-spoiling" if inferiorproducts are introduced and result in user dissatisfaction. Completesystems involve the integration of light sources and optics, energysupply, and energy storage. A natural starting point for evaluatingproduct quality is to focus on the individual light sources. This reportdescribes testing results for batches of 10 5mm white LEDs from 26manufacturers. Efficacies and color properties are presented.

CATALYSIS SCIENCE INITIATIVE: From First Principles Design to Realization of Bimetallic Catalysts for Enhanced Selectivity (open access)

CATALYSIS SCIENCE INITIATIVE: From First Principles Design to Realization of Bimetallic Catalysts for Enhanced Selectivity

In this project, we have integrated state-of-the-art Density Functional Theory (DFT) models of heterogeneous catalytic processes with high-throughput screening of bimetallic catalytic candidates for important industrial problems. We have studied a new class of alloys characterized by a surface composition different from the bulk composition, and investigated their stability and activity for the water-gas shift reaction and the oxygen reduction reaction. The former reaction is an essential part of hydrogen production; the latter is the rate-limiting step in low temperature H2 fuel cells. We have identified alloys that have remarkable stability and activity, while having a much lower material cost for both of these reactions. Using this knowledge of bimetallic interactions, we have also made progress in the industrially relevant areas of carbohydrate reforming and conversion of biomass to liquid alkanes. One aspect of this work is the conversion of glycerol (a byproduct of biodiesel production) to synthesis gas. We have developed a bifunctional supported Pt catalyst that can cleave the carbon-carbon bond while also performing the water-gas shift reaction, which allows us to better control the H2:CO ratio. Knowledge gained from the theoretical metal-metal interactions was used to develop bimetallic catalysts that perform this reaction at low temperature, allowing …

Climate Change: Financial Risks to Federal and Private Insurers in Coming Decades are Potentially Significant (open access)

Climate Change: Financial Risks to Federal and Private Insurers in Coming Decades are Potentially Significant

Testimony issued by the Government Accountability Office with an abstract that begins "Weather-related events in the United States have caused tens of billions of dollars in damages annually over the past decade. A major portion of these losses is borne by private insurers and by two federal insurance programs-- the Federal Emergency Management Agency's National Flood Insurance Program (NFIP), which insures properties against flooding, and the Department of Agriculture's Federal Crop Insurance Corporation (FCIC), which insures crops against drought or other weather disasters. In this testimony, GAO (1) describes how climate change may affect future weather-related losses, (2) provides information on past insured weather-related losses, and (3) determines what major private insurers and federal insurers are doing to prepare for potential increases in such losses. This testimony is based on a report entitled Climate Change: Financial Risks to Federal and Private Insurers in Coming Decades are Potentially Significant (GAO-07-285) released on April 19, 2007."

Crop Insurance: Continuing Efforts Are Needed to Improve Program Integrity and Ensure Program Costs Are Reasonable (open access)

Crop Insurance: Continuing Efforts Are Needed to Improve Program Integrity and Ensure Program Costs Are Reasonable

Testimony issued by the Government Accountability Office with an abstract that begins "The U.S. Dept. of Agriculture's (USDA) Risk Management Agency (RMA) administers the federal crop insurance program in partnership with private insurers. In 2006, the program cost $3.5 billion, including millions in losses from fraud, waste, and abuse, according to USDA. The Agricultural Risk Protection Act of 2000 granted RMA authority to renegotiate the terms of RMA's standard reinsurance agreement with companies once over 5 years. This testimony is based on GAO's 2005 report, Crop Insurance: Actions Needed to Reduce Program's Vulnerability to Fraud, Waste, and Abuse, as well as new analyses this Committee requested on underwriting gains and administrative and operating expenses USDA paid companies. GAO discusses (1) USDA's processes to address fraud, waste, and abuse; (2) extent the program's design makes it vulnerable to abuse; and (3) reasonableness of underwriting gains and other expenses. USDA agreed with most of GAO's 2005 recommendations to improve program integrity. RMA agreed that GAO's new analyses were technically accurate."

Development of Advanced Wear and Corrosion Resistant Systems Through Laser Surface Alloying and Materials Simulations (open access)

Development of Advanced Wear and Corrosion Resistant Systems Through Laser Surface Alloying and Materials Simulations

Laser surfacing in the form of cladding, alloying, and modifications are gaining widespread use because of its ability to provide high deposition rates, low thermal distortion, and refined microstructure due to high solidification rates. Because of these advantages, laser surface alloying is considered a prime candidate for producing ultra-hard coatings through the establishment or in situ formation of composite structures. Therefore, a program was conducted by the Applied Research Laboratory, Pennsylvania State University and Oak Ridge National Laboratory to develop the scientific and engineering basis for performing laser-based surface modifications involving the addition of hard particles, such as carbides, borides, and nitrides, within a metallic matrix for improved wear, fatigue, creep, and corrosion resistance. This has involved the development of advanced laser processing and simulation techniques, along with the refinement and application of these techniques for predicting and selecting materials and processing parameters for the creation of new surfaces having improved properties over current coating technologies. This program has also resulted in the formulation of process and material simulation tools capable of examining the potential for the formation and retention of composite coatings and deposits produced using laser processing techniques, as well as positive laboratory demonstrations in producing these coatings. …

ESTIMATING THE STRENGTH OF SINGLE-ENDED DISLOCATION SOURCES IN MICROMETER-SIZED SINGLE CRYSTALS (open access)

ESTIMATING THE STRENGTH OF SINGLE-ENDED DISLOCATION SOURCES IN MICROMETER-SIZED SINGLE CRYSTALS

A recent study indicated that the behavior of single-ended dislocation sources contributes to the flow strength of micrometer-scale crystals. In this study 3D discrete dislocation dynamics simulations of micrometer-sized volumes are used to calculate the effects of anisotropy of dislocation line tension (increasing Poisson's ratio, {nu}) on the strength of single-ended dislocation sources and, to compare them with the strength of double-ended sources of equal length. This is done by directly modeling their plastic response within a 1 micron cubed FCC Ni single crystal using DDS. In general, double-ended sources are stronger than single-ended sources of an equal length and exhibit no significant effects from truncating the long-range elastic fields at this scale. The double-ended source strength increases with Poisson ratio ({nu}), exhibiting an increase of about 50% at u = 0.38 (value for Ni) as compared to the value at {nu} = 0. Independent of dislocation line direction, for {nu} greater than 0.20, the strengths of single-ended sources depend upon the sense of the stress applied. The value for {alpha}, in the expression for strength, {tau} = {alpha}(L){micro}b/L is shown to vary from 0.4 to 0.84 depending upon the character of the dislocation and the direction of operation of …

Food Stamp Program: Use of Alternative Methods to Apply for and Maintain Benefits Could Be Enhanced by Additional Evaluation and Information on Promising Practices

A letter report issued by the Government Accountability Office with an abstract that begins "One in 12 Americans participates in the federal Food Stamp Program, administered by the Food and Nutrition Service (FNS). States have begun offering individuals alternatives to visiting the local assistance office to apply for and maintain benefits, such as mail-in procedures, call centers, and on-line services. GAO was asked to examine: (1) what alternative methods states are using to increase program access; (2) what is known about the results of these methods, particularly on program access for target groups, decision accuracy, and administrative costs; and (3) what actions states have taken to maintain program integrity while implementing alternative methods. GAO surveyed state food stamp administrators, reviewed five states in depth, analyzed FNS data and reports, and interviewed program officials and stakeholders."
