Ring Walking/Oxidative Addition Reactions for the Controlled Synthesis of Conjugated Polymers
Power conversion efficiencies of plastic solar cells depend strongly on the molecular weight characteristics of the semiconducting polymers used for their fabrication. The synthesis of these materials typically relies on transition metal mediated catalytic reactions. In many instances, the ideal structures cannot be attained because of deficiencies in these reactions, particularly when it comes to being able to achieve high number average molecular weights and narrow molecular weight distributions. Another important conjugated polymer structure of interest is one in which a single functional group is attached at the end group of the chain. Such systems would be ideal for modifying surface properties at interfaces and for labeling biomolecular probes used in fluorescent biosensors. To respond to the challenges above, our efforts have centered on the design of homogenous transition metal complexes that are easy to prepare and effective in carrying out living, or quasi-living, condensative chain polymerization reactions. The key mechanistic challenge for the success of this reaction is to force the insertion of one monomer unit at a time via a process that involves migration of the transition metal-containing fragment to one terminus of the polymer chain. Chain growth characteristics are therefore favored when the metal does not dissociate …

Slot-Controlled Airports: FAA's Rules Could Be Improved to Enhance Competition and Use of Available Capacity
A letter report issued by the Government Accountability Office with an abstract that begins "The 16 new beyond-perimeter flights that were authorized in 2012 for Reagan National Airport are likely to have a limited effect on the airports in the Washington, D.C., area. Reagan National has sufficient runway capacity to accommodate the new beyond-perimeter flights and, with some improvements to baggage handling and security screening facilities, will have sufficient terminal capacity. Reagan National is routinely operating below 67 hourly takeoffs and landings ("slots")--the maximum number authorized in any one hour--mostly because general aviation or other unscheduled aircraft operations decreased substantially after new security restrictions were imposed following the September 11, 2001, terrorist attacks. GAO's analysis found that the new beyond-perimeter flights could add a maximum of about 5 percent of 2011 passenger levels at Reagan National, and if all of that increase came from passengers moving from Dulles International or Baltimore-Washington International Thurgood Marshall, these airports could experience a maximum decline of 4.1 percent of 2011 passenger levels. As a result, because Reagan National and Dulles generally do not share what are largely fixed costs, passengers shifting from Dulles to the new beyond-perimeter flights at Reagan National would, in the …

Terrorist Watch List Screening and Brady Background Checks for Firearms
The November 2009 shooting at Fort Hood, TX, renewed interest in terrorist watchlist screening and Brady background checks for firearms through the National Instant Criminal Background Check System (NICS). In the 110th Congress, Senator Frank Lautenberg and Representative Peter King introduced a bill based on a legislative proposal developed by DOJ that would have authorized the Attorney General to deny the transfer of firearms or the issuance of firearms (and explosives) licenses/permits to "dangerous terrorists." They reintroduced this proposal in the 111th Congress and supporters dubbed it the "Terror Gap" proposal. It was reintroduced once again in the 112th Congress. The Terror Gap proposal raises several potential issues for Congress, which are discussed in this report.

Export Controls: U.S. Agencies Need to Assess Control List Reform's Impact on Compliance Activities
A letter report issued by the Government Accountability Office with an abstract that begins "U.S. agencies engaged in export controls use various compliance activities to prevent the diversion or misuse of exported items against U.S. interests or allies and reduce illicit transshipment risk. Compliance activities include (1) vetting transactions prior to export, (2) analyzing shipping data and monitoring the end use of items, and (3) educating companies and foreign governments about illicit transshipment risks. To vet transactions, agencies review license applications for the export of controlled items, consult multiple lists of entities known or suspected of violating export control laws or regulations, and screen foreign end users to determine their eligibility to receive items without a license. Agencies also review shipping records to identify patterns of abuse and to plan end-use checksvisiting foreign companies to verify the approved use and location of exported items on both licensed items and those eligible for export without a license. From 2008 to 2010, Commerce conducted 56 percent of its end-use checks on unlicensed exports. In the 13 transshipment countries, unlicensed exports accounted for about 94 percent of unfavorable end-use check determinations, which indicates that the end use or end user of an export …

Transformation of Themes, Controlled Pianistic Textures, and Coloristic Effects in Liszt's Hungarian Rhapsodies Nos 6, 10, and 12
Liszt's Hungarian Rhapsodies are uniformly considered highly challenging in terms of technical execution. However, their artistic value is frequently questioned. This dissertation examines the compositional elements that are often overlooked in these virtuoso works, and provides a viewpoint into their interpretative characteristics. Furthermore, it pursues a claim that besides being excellent performance pieces, these works also make an intriguing contribution to Liszt scholarship, and deserve meaningful consideration in terms of their artistic quality. Following the Introduction (Chapter 1), Chapter 2 provides a brief historical perspective of the critical affirmation Liszt the composer encountered from the musical society. It also includes a short background on Liszt's Hungarian Rhapsodies, as well as the general reactions these works evoked from pianists, audiences, and scholars, during the time they were composed to the present day. As the main body of the dissertation, Chapter 3 investigates the three primary compositional concepts found in Rhapsodies Nos. 6, 10, and 12. These concepts are divided into three subchapters: Transformation of Themes, Controlled Pianistic Textures, and Coloristic Effects. Each of these subchapters provides explanatory information, as well as some of the most characteristic passages presented.

Photovoltaic Materials
The goal of the current project was to help make the US solar industry a world leader in the manufacture of thin film photovoltaics. The overall approach was to leverage ORNL’s unique characterization and processing technologies to gain a better understanding of the fundamental challenges for solar cell processing and apply that knowledge to targeted projects with industry members. ORNL has the capabilities in place and the expertise required to understand how basic material properties including defects, impurities, and grain boundaries affect the solar cell performance. ORNL also has unique processing capabilities to optimize the manufacturing process for fabrication of high efficiency and low cost solar cells. ORNL recently established the Center for Advanced Thin-film Systems (CATS), which contains a suite of optical and electrical characterization equipment specifically focused on solar cell research. Under this project, ORNL made these facilities available to industrial partners who were interested in pursuing collaborative research toward the improvement of their product or manufacturing process. Four specific projects were pursued with industrial partners: Global Solar Energy is a solar industry leader in full scale production manufacturing highly-efficient Copper Indium Gallium diSelenide (CIGS) thin film solar material, cells and products. ORNL worked with GSE to develop …

ENHANCED SAFEGUARDS: THE ROLE OF SMART FUNCTIONAL COATINGS FOR TAMPER INDICATION
This work investigates the synthesis of smart functional coatings (SFC) using chemical solution deposition methods. Chemical solution deposition methods have recently received attention in the materials research community due to several unique advantages that include low temperature processing, high homogeneity of final products, the ability to fabricate materials with controlled surface properties and pore structures, and the ease of dopant incorporation in controlled concentrations. The optical properties of thin films were investigated using UV-Vis spectroscopy, Raman, SEM and EDS, with the aim of developing a protective transparent coating for a ceramic surface as a first line of defense for tamper indication. The signature produced by the addition of rare earth dopants will be employed as an additional tamper indicating feature. The integration of SFC's as part of a broader verification system such as an electronic seals can provide additional functionality and defense in depth. SFC's can improve the timeliness of detection by providing a robust, in-situ verifiable tamper indication framework.

Final Scientific/Technical Report. A closed path methane and water vapor gas analyzer
Robust, economical, low-power and reliable closed-path methane (CH4), carbon dioxide (CO2), and water vapor (H2O) analyzers suitable for long-term measurements are not readily available commercially. Such analyzers are essential for quantifying the amount of CH4 and CO2 released from various ecosystems (wetlands, rice paddies, forests, etc.) and other surface contexts (e.g. landfills, animal husbandry lots, etc.), and for understanding the dynamics of the atmospheric CH4 and CO2 budget and their impact on climate change and global warming. The purpose of this project is to develop a closed-path methane, carbon dioxide gas and water vapor analyzer capable of long-term measurements in remote areas for global climate change and environmental research. The analyzer will be capable of being deployed over a wide range of ecosystems to understand methane and carbon dioxide exchange between the atmosphere and the surface. Measurements of methane and carbon dioxide exchange need to be made all year-round with limited maintenance requirements. During this Phase II effort, we successfully completed the design of the electronics, optical bench, trace gas detection method and mechanical infrastructure. We are using the technologies of two vertical cavity surface emitting lasers, a multiple-pass Herriott optical cell, wavelength modulation spectroscopy and direct absorption to measure …

Information Technology: FDA Needs to Fully Implement Key Management Practices to Lessen Modernization Risks
A letter report issued by the Government Accountability Office with an abstract that begins "While FDA has taken several important steps toward modernizing its IT environment, much remains to be done. FDA reported spending about $400 million for IT investments in fiscal year 2011; however, the agency currently lacks a comprehensive IT inventory that identifies and provides key information about the systems it uses and is developing. Office of Management and Budget (OMB) and GAO guidance call for federal agencies to maintain such an inventory in order to monitor and manage their IT investments. This inventory should include information on each system, such as costs, functionality or purpose, and status. However, FDA does not have such a comprehensive list of its systems. Instead, the agency points to budget documents required by OMB, which included information on 44 IT investments for fiscal year 2011. The agency also provided a partial list of 21 mission-critical systems and modernization initiatives. Nonetheless, agency officials acknowledged that these documents do not identify all FDAs systems or the complete costs, purpose, or status of each system. Until the agency has a complete and comprehensive inventory, it will lack critical information needed to effectively assess its IT …

Impacts of Antifoam Additions and Argon Bubbling on Defense Waste Processing Facility Reduction/Oxidation
During melting of HLW glass, the REDOX of the melt pool cannot be measured. Therefore, the Fe{sup +2}/{Sigma}Fe ratio in the glass poured from the melter must be related to melter feed organic and oxidant concentrations to ensure production of a high quality glass without impacting production rate (e.g., foaming) or melter life (e.g., metal formation and accumulation). A production facility such as the Defense Waste Processing Facility (DWPF) cannot wait until the melt or waste glass has been made to assess its acceptability, since by then no further changes to the glass composition and acceptability are possible. therefore, the acceptability decision is made on the upstream process, rather than on the downstream melt or glass product. That is, it is based on 'feed foward' statistical process control (SPC) rather than statistical quality control (SQC). In SPC, the feed composition to the melter is controlled prior to vitrification. Use of the DWPF REDOX model has controlled the balanjce of feed reductants and oxidants in the Sludge Receipt and Adjustment Tank (SRAT). Once the alkali/alkaline earth salts (both reduced and oxidized) are formed during reflux in the SRAT, the REDOX can only change if (1) additional reductants or oxidants are added …

Information Sharing: DHS Has Demonstrated Leadership and Progress, but Additional Actions Could Help Sustain and Strengthen Efforts
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) has made progress in achieving its information-sharing mission, but could take additional steps to improve its efforts. Specifically, DHS has demonstrated leadership commitment by establishing a governance board to serve as the decision-making body for DHS information-sharing issues. The board has enhanced collaboration among DHS components and identified a list of key information-sharing initiatives. The board has also developed and documented a process to prioritize some of the initiatives for additional oversight and support. However, because DHS has not revised its policies and guidance to include processes for identifying information-sharing gaps and the results; analyzing root causes of those gaps; and identifying, assessing, and mitigating risks of removing incomplete initiatives from its list, it does not have an institutional record that would help it replicate and sustain those information-sharing efforts. Overall, DHSs key information-sharing initiatives have progressed, and most have met interim milestones. However, progress has slowed for half of the 18 key initiatives, in part because of funding constraints. For example, 5 of DHSs top 8 priority information-sharing initiatives currently face funding shortfalls. The board has not been able …

The SM and NLO Multileg Working Group: Summary Report
After years of waiting, and after six Les Houches workshops, the era of LHC running is finally upon us, albeit at a lower initial center-of-mass energy than originally planned. Thus, there has been a great sense of anticipation from both the experimental and theoretical communities. The last two years, in particular, have seen great productivity in the area of multi-parton calculations at leading order (LO), next-to-leading order (NLO) and next-to-next-to-leading order (NNLO), and this productivity is reflected in the proceedings of the NLM group. Both religions, Feynmanians and Unitarians, as well as agnostic experimenters, were well-represented in both the discussions at Les Houches, and in the contributions to the write-up. Next-to-leading order (NLO) is the first order at which the normalization, and in some cases the shape, of perturbative cross sections can be considered reliable. This can be especially true when probing extreme kinematic regions, as for example with boosted Higgs searches considered in several of the contributions to this writeup. A full understanding for both standard model and beyond the standard model physics at the LHC requires the development of fast, reliable programs for the calculation of multi-parton final states at NLO. There have been many advances in the …

Induction Consolidation of Thermoplastic Composites Using Smart Susceptors
This project has focused on the area of energy efficient consolidation and molding of fiber reinforced thermoplastic composite components as an energy efficient alternative to the conventional processing methods such as autoclave processing. The expanding application of composite materials in wind energy, automotive, and aerospace provides an attractive energy efficiency target for process development. The intent is to have this efficient processing along with the recyclable thermoplastic materials ready for large scale application before these high production volume levels are reached. Therefore, the process can be implemented in a timely manner to realize the maximum economic, energy, and environmental efficiencies. Under this project an increased understanding of the use of induction heating with smart susceptors applied to consolidation of thermoplastic has been achieved. This was done by the establishment of processing equipment and tooling and the subsequent demonstration of this fabrication technology by consolidating/molding of entry level components for each of the participating industrial segments, wind energy, aerospace, and automotive. This understanding adds to the nation's capability to affordably manufacture high quality lightweight high performance components from advanced recyclable composite materials in a lean and energy efficient manner. The use of induction heating with smart susceptors is a precisely controlled …
