An Ab Initio Approach Towards Engineering Fischer-Tropsch Surface Chemistry (open access)

An Ab Initio Approach Towards Engineering Fischer-Tropsch Surface Chemistry

As petroleum prices continue to rise and the United States seeks to reduce its dependency on foreign oil, there is a renewed interest in the research and development of more efficient and alternative energy sources, such as fuel cells. One approach is to utilize processes that can produce long-chain hydrocarbons from other sources. One such reaction is Fischer-Tropsch synthesis. Fischer-Tropsch synthesis is a process by which syngas (CO and H{sub 2}) is converted to higher molecular weight hydrocarbons. The reaction involves a complex set of bond-breaking and bond-making reactions, such as CO and H{sub 2} activation, hydrocarbon hydrogenation reactions, and hydrocarbon coupling reactions. This report details our initial construction of an ab initio based kinetic Monte Carlo code that can be used to begin to simulate Fischer-Tropsch synthesis over model Co(0001) surfaces. The code is based on a stochastic kinetic formalism that allows us to explicitly track the transformation of all reactants, intermediates and products. The intrinsic kinetics for the simulations were derived from the ab initio results that we reported in previous year summaries.

Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways (open access)

Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways

Significant energy savings can be achieved in commercial building operation, along with increased comfort and control for occupants, through the implementation of advanced technologies. This document provides a market assessment of existing building sensors and controls and presents a range of technology pathways (R&D options) for pursuing advanced sensors and building control strategies. This paper is actually a synthesis of five other white papers: the first describes the market assessment including estimates of market potential and energy savings for sensors and control strategies currently on the market as well as a discussion of market barriers to these technologies. The other four cover technology pathways: (1) current applications and strategies for new applications, (2) sensors and controls, (3) networking, security, and protocols and standards, and (4) automated diagnostics, performance monitoring, commissioning, optimal control and tools. Each technology pathway chapter gives an overview of the technology or application. This is followed by a discussion of needs and the current status of the technology. Finally, a series of research topics is proposed.

Agricultural Issues in the 109th Congress (open access)

Agricultural Issues in the 109th Congress

A number of issues affecting U.S. agriculture are receiving attention during the 109th Congress. Some are related to new initiatives or to unfinished legislation from the 108th Congress; others have been the focus of ongoing congressional oversight. Although the current (2002) farm bill (P.L. 107-171) generally does not expire until 2007, the agriculture committees could begin hearings on a new measure later this year. Meanwhile, the agriculture committees are required by the adopted FY2006 budget resolution to report legislation that reduces spending on mandatory food and agriculture support programs by $3 billion over the next five years. Other issues of importance to agriculture during the 109th Congress include the possible reauthorization of an expiring dairy support program; multilateral and bilateral trade negotiations; concerns about agroterrorism, food safety, and animal and plant diseases (e.g., “mad cow” disease and Asian soybean rust); high energy costs; environmental issues; and a number of agricultural marketing matters. This report will be updated if significant developments ensue.

An event-level tagging technique is developed, which facilitates the accurate determination of doubly Cabibbo-suppressed resonance contributions by suppressing background from Cabibbo-favored decays. The branching ratio is measured as R = (0.214 {+-} 0.008 (stat) {+-} 0.008 (syst))%, with (46.1 {+-} 3.3 (stat) {+-} 2.9 (syst))% of D{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0} decays proceeding through the channel D{sup 0} {yields} K*{sup +}{pi}{sup -}. The data are consistent with the null-D-mixing hypothesis at a confidence level of 10%, and the expected value of {+-} {radical}(x{sup 2} + y{sup 2}) is measured as -0.013 {+-} 0.010 (stat), indicating negative interference between mixing and doubly Cabibbo-suppressed decay.

Benzene Generation Testing for Tank 48H Waste Disposition (open access)

Benzene Generation Testing for Tank 48H Waste Disposition

In support for the Aggregation option1, researchers performed a series of tests using actual Tank 48H slurries. The tests were designed to examine potential benzene generation issues if the Tank 48H slurry is disposed to Saltstone. Personnel used the archived Tank 48H sample (HTF-E-03-127, collected September 17, 2003) for the experiments. The tests included a series of three experiments (Tests A, B, and F) performed in duplicate, giving a total of six experiments. Test A used Tank 48H slurry mixed with {approx}20:1 with Defense Waste Processing Facility (DWPF) Recycle from Tanks 21H and 22H. Test B used Tank 48H slurry mixed with {approx}2.7:1 with DWPF Recycle from Tanks 21H and 22H, while Test F used Tank 48H slurry as-is. Tests A and B occurred at 45 C, while Test F occurred at 55 C. Over a period of 8 weeks, personnel collected samples for analysis, once per week. Each sample was tested with the in-cell gamma counter. The researchers noted a decline in the cesium activity in solution which is attributed to temperature dependence of the complex slurry equilibrium. Selected samples were sent to ADS for potassium, boron, and cesium analysis. The benzene generation rate was inferred from the TPB …

Border Security: Fences Along the U.S. International Border (open access)

Border Security: Fences Along the U.S. International Border

This report outlines the issues involved with the Department of Homeland Security’s (DHS’s) completion of a three-tiered, 14-mile fence, along the border near San Diego, California. The state of California has delayed completion of the fence due primarily to legal and policy conflicts with its federally-approved, state-run Coastal Management Program. Current authorization for the fence only allows the waiver of the Endangered Species Act and the National Environmental Policy Act. During the 108th Congress, a variety of proposals were introduced that would have allowed the department to waive a number of other environmental, conservation, and cultural laws and requirements to varying degrees. Similar proposals are likely to surface again during the 109th Congress.

A Calibration to Predict Concentrations of Impurities in Plutonium Oxide by Prompt Gamma Analysis (open access)

A Calibration to Predict Concentrations of Impurities in Plutonium Oxide by Prompt Gamma Analysis

Prompt gamma (PG) analysis has been used to identify the presence of certain impurities in plutonium oxide, which has been stored in 3013 containers. A regression analysis was used to evaluate the trends between the count rates obtained from PG analysis and the concentration of the impurities in plutonium oxide samples measured by analytical chemistry techniques. The results of the analysis were used to obtain calibration curves, which may be used to predict the concentration of Al, Be, Cl, F, Mg, and Na in the 3013 containers. The scatter observed in the data resulted from several factors including sample geometry, error in sampling for chemical assay, statistical counting error, and intimacy of mixing of impurities and plutonium. Standards prepared by mixing plutonium oxide with CaF{sub 2}, NaCl, and KCl show that intimacy mixing and sampling error have the largest influence on the results. Although these factors are difficult to control, the calibrations are expected to yield semiquantitative results that are sufficient for the purpose of ordering or ranking.
