Direct Observation of Room-Temperature Polar Ordering in Colloidal GeTe Nanocrystals
Ferroelectrics and other materials that exhibit spontaneous polar ordering have demonstrated immense promise for applications ranging from non-volatile memories to microelectromechanical systems. However, experimental evidence of polar ordering and effective synthetic strategies for accessing these materials are lacking for low-dimensional nanomaterials. Here, we demonstrate the synthesis of size-controlled nanocrystals of the polar material germanium telluride (GeTe) using colloidal chemistry and provide the first direct evidence of room-temperature polar ordering in nanocrystals less than 5 nm in size using aberration-corrected transmission electron microscopy. Synchrotron x-ray diffraction and Raman studies demonstrate a sizeable polar distortion and a reversible size-dependent polar phase transition in these nanocrystals. The stability of polar ordering in solution-processible nanomaterials suggests an economical avenue to Tbit/in2-density non-volatile memory devices and other applications.

High-Level Waste Glass Formulation Model Sensitivity Study 2009 Glass Formulation Model Versus 1996 Glass Formulation Model
This document presents the differences between two HLW glass formulation models (GFM): The 1996 GFM and 2009 GFM. A glass formulation model is a collection of glass property correlations and associated limits, as well as model validity and solubility constraints; it uses the pretreated HLW feed composition to predict the amount and composition of glass forming additives necessary to produce acceptable HLW glass. The 2009 GFM presented in this report was constructed as a nonlinear optimization calculation based on updated glass property data and solubility limits described in PNNL-18501 (2009). Key mission drivers such as the total mass of HLW glass and waste oxide loading are compared between the two glass formulation models. In addition, a sensitivity study was performed within the 2009 GFM to determine the effect of relaxing various constraints on the predicted mass of the HLW glass.

OPERATIONAL CHALLENGES IN MIXING AND TRANSFER OF HIGH YIELD STRESS SLUDGE WASTE
The ability to mobilize and transport non-Newtonian waste is essential to advance the closure of highly radioactive storage tanks. Recent waste removal operations from Tank 12H at the Savannah River Site (SRS) encountered sludge mixtures with a yield stress too high to pump. The waste removal equipment for Tank 12H was designed to mobilize and transport a diluted slurry mixture through an underground 550m long (1800 ft) 0.075m diameter (3 inch) pipeline. The transfer pump was positioned in a well casing submerged in the sludge slurry. The design allowed for mobilized sludge to enter the pump suction while keeping out larger tank debris. Data from a similar tank with known rheological properties were used to size the equipment. However, after installation and startup, field data from Tank 12H confirmed the yield stress of the slurry to exceed 40 Pa, whereas the system is designed for 10 Pa. A revision to the removal strategy was required, which involved metered dilution, blending, and mixing to ensure effective and safe transfer performance. The strategy resulted in the removal of over 255,000 kgs of insoluble solids with four discrete transfer evolutions for a total transfer volume of 2400 m{sup 3} (634,000 gallons) of sludge …

Oral History Interview with Jesse Dwain Holmes, December 7, 2009
The National Museum of the Pacific War presents an oral interview with Jesse Dwain Holmes. Holmes joined the Navy in 1944 and attended boot camp in San Diego. Upon completion of gunnery school, he boarded the SS John T. McMillan (1943) as an armed guard. After joining a convoy at Leyte, the crew was at general quarters every hour for air raids. Whenever the ship laid smoke screens, Holmes didn’t fire a single round, for fear of engaging in friendly fire. He returned home briefly after 10 months at sea and redeployed to Okinawa, where he fired a 3-inch gun at kamikazes. He then served on Guam as a postman to enjoy some shore duty. Holmes sailed to Wake Island after the war ended and went ashore for its surrender. After being discharged in December 1945, he was grateful to return home unscathed despite the Naval Armed Guard's heavy casualty rates.

Performance Analysis: ITS Data through September 30, 2009
Data from ITS was analyzed to understand the issues at LLNL and to identify issues that may require additional management attention and these that meet the threshold for reporting to the DOE Noncompliance Tracking System (NTS). In this report we discuss assessments and issues entered in ITS and compare the number and type presently entered in ITS to previous time periods. Issues reported in ITS were evaluated and discussed. The analysis identified two noncompliances that meet the threshold for reporting to the DOE NTS. All of the data in ITS is analyzed; however, the primary focus of this report is to meet requirements for performance analysis of specific functional areas. The DOE Office of Enforcement expects LLNL to 'implement comprehensive management and independent assessments that are effective in identifying deficiencies and broader problems in safety and security programs, as well as opportunities for continuous improvement within the organization' and to 'regularly perform assessments to evaluate implementation of the contractor's's processes for screening and internal reporting.' LLNL has a self-assessment program, described in the document applicable during this time period, ES&H Manual Document 4.1, that includes line, management and independent assessments. LLNL also has in place a process to identify and …

Pseudo-transient Continuation Based Variable Relaxation Solve in Nonlinear Magnetohydrodynamic Simulations
Efficient and robust Variable Relaxation Solver, based on pseudo-transient continuation, is developed to solve nonlinear anisotropic thermal conduction arising from fusion plasma simulations. By adding first and/or second order artificial time derivatives to the system, this type of method advances the resulting time-dependent nonlinear PDEs to steady state, which is the solution to be sought. In this process, only the stiffness matrix itself is involved so that the numerical complexity and errors can be greatly reduced. In fact, this work is an extension of integrating efficient linear elliptic solvers for fusion simulation on Cray XIE. Two schemes are derived in this work, first and second order Variable Relaxations. Four factors are observed to be critical for efficiency and preservation of solution's symmetric structure arising from periodic boundary condition: refining meshes in different coordinate directions, initializing nonlinear process, varying time steps in both temporal and spatial directions, and accurately generating nonlinear stiffness matrix. First finer mesh scale should be taken in strong transport direction; Next the system is carefully initialized by the solution with linear conductivity; Third, time step and relaxation factor are vertex-based varied and optimized at each time step; Finally, the nonlinear stiffness matrix is updated by just scaling …

Social Security: Options to Protect Benefits for Vulnerable Groups When Addressing Program Solvency
Correspondence issued by the Government Accountability Office with an abstract that begins "For over 70 years, Social Security has been the foundation of retirement income for American workers and their families and has been instrumental in reducing poverty among the elderly. The Congressional Research Service estimates that if Social Security benefits did not exist, an estimated 44 percent of all elderly people would be poor today. Still, some people who receive Social Security retirement benefits remain vulnerable to poverty in old age. The elderly poverty rate in 2007 was 9.7 percent. In addition, the long-term financing shortfall currently facing the Social Security program is growing and has made reform of the program a priority for policy makers. Thus, the nation faces the challenge of improving long-term program solvency, while also ensuring benefit adequacy for economically vulnerable beneficiaries. Many Social Security reform proposals have suggested modifying the system to restore its financial balance by reducing benefits or increasing payroll or other taxes, and several also include options to address concerns about benefit adequacy for economically vulnerable groups of beneficiaries. Economically vulnerable beneficiaries generally have limited income from other sources, such as employer-sponsored pension plans or personal savings, and therefore depend heavily …

Technical Report
The aim of the summer school is to nurture the next generation of scientists so that the community will have sufficient manpower to realize the next generation facility for rare-isotope beams (FRIB) and effectively use it when FRIB comes online. A special emphasis will be made to train Ph.D. students from US universities and young post-docs starting to work in one of the fields related to rare-isotope beams. The format of the school is morning lectures, given by prominent researchers in the field, followed by hands-on training sessions in the afternoon. The students will be instructed in how to produce a radioactive ion beam using the National Superconducting Cyclotron Laboratory Coupled Cyclotron Facility. On the last day of the school they will have the opportunity to produce a beam. The School is an annual event and is jointly organized by the 88-Inch Cyclotron, ATLAS, HRIBF, N-Division/LLNL and NSCL, and with the exception of LLNL is rotating among these laboratories. This proposal is for subsistence support for graduate students and post-docs attending the school.

Thin Silicon MEMS Contact-Stress Sensor
This work offers the first, thin, MEMS contact-stress (CS) sensor capable of accurate in situ measruement of time-varying, contact-stress between two solid interfaces (e.g. in vivo cartilage contact-stress and body armor dynamic loading). This CS sensor is a silicon-based device with a load sensitive diaphragm. The diaphragm is doped to create piezoresistors arranged in a full Wheatstone bridge. The sensor is similar in performance to established silicon pressure sensors, but it is reliably produced to a thickness of 65 {micro}m. Unlike commercial devices or other research efforts, this CS sensor, including packaging, is extremely thin (< 150 {micro}m fully packaged) so that it can be unobtrusively placed between contacting structures. It is built from elastic, well-characterized materials, providing accurate and high-speed (50+ kHz) measurements over a potential embedded lifetime of decades. This work explored sensor designs for an interface load range of 0-2 MPa; however, the CS sensor has a flexible design architecture to measure a wide variety of interface load ranges.
