2012 CORRELATED ELECTRON SYSTEMS GRC AND GRS, JUNE 23-29, 2012 (open access)

2012 CORRELATED ELECTRON SYSTEMS GRC AND GRS, JUNE 23-29, 2012

The 2012 Gordon Conference on Correlated Electron Systems will present cutting-edge research on emergent properties arising from strong electronic correlations. While we expect the discussion at the meeting to be wide-ranging, given the breadth of the title subject matter, we have chosen several topics to be the particular focus of the talks. These are New Developments in Single and Bilayer Graphene, Topological States of Matter, including Topological Insulators and Spin Liquids, the Interplay Between Magnetism and Unconventional Superconductivity, and Quantum Critical Phenomena in Metallic Systems. We also plan to have shorter sessions on Systems Far From Equilibrium, Low Dimensional Electron Fluids, and New Directions (which will primarily focus on new experimental methodologies and their interpretation).

Adsorption of Atmospheric Gases on Pu Surfaces (open access)

Adsorption of Atmospheric Gases on Pu Surfaces

Surface adsorption represents a competition between collision and scattering processes that depend on surface energy, surface structure and temperature. The surface reactivity of the actinides can add additional complexity due to radiological dissociation of the gas and electronic structure. Here we elucidate the chemical bonding of gas molecules adsorbed on Pu metal and oxide surfaces. Atmospheric gas reactions were studied at 190 and 300 K using x-ray photoelectron spectroscopy. Evolution of the Pu 4f and O 1s core-level states were studied as a function of gas dose rates to generate a set of Langmuir isotherms. Results show that the initial gas dose forms Pu{sub 2}O{sub 3} on the Pu metal surface followed by the formation of PuO{sub 2} resulting in a layered oxide structure. This work represents the first steps in determining the activation energy for adsorption of various atmospheric gases on Pu.

Advanced, High Power, Next Scale, Wave Energy Conversion Device (open access)

Advanced, High Power, Next Scale, Wave Energy Conversion Device

The project conducted under DOE contract DE‐EE0002649 is defined as the Advanced, High Power, Next Scale, Wave Energy Converter. The overall project is split into a seven‐stage, gated development program. The work conducted under the DOE contract is OPT Stage Gate III work and a portion of Stage Gate IV work of the seven stage product development process. The project effort includes Full Concept Design & Prototype Assembly Testing building on our existing PowerBuoy� technology to deliver a device with much increased power delivery. Scaling‐up from 150kW to 500kW power generating capacity required changes in the PowerBuoy design that addressed cost reduction and mass manufacturing by implementing a Design for Manufacturing (DFM) approach. The design changes also focused on reducing PowerBuoy Installation, Operation and Maintenance (IO&M) costs which are essential to reducing the overall cost of energy. In this design, changes to the core PowerBuoy technology were implemented to increase capability and reduce both CAPEX and OPEX costs. OPT conceptually envisaged moving from a floating structure to a seabed structure. The design change from a floating structure to seabed structure would provide the implementation of stroke‐ unlimited Power Take‐Off (PTO) which has a potential to provide significant power delivery improvement …

ADVANCED OXIDATION: OXALATE DECOMPOSITION TESTING WITH OZONE (open access)

ADVANCED OXIDATION: OXALATE DECOMPOSITION TESTING WITH OZONE

At the Savannah River Site (SRS), oxalic acid is currently considered the preferred agent for chemically cleaning the large underground Liquid Radioactive Waste Tanks. It is applied only in the final stages of emptying a tank when generally less than 5,000 kg of waste solids remain, and slurrying based removal methods are no-longer effective. The use of oxalic acid is preferred because of its combined dissolution and chelating properties, as well as the fact that corrosion to the carbon steel tank walls can be controlled. Although oxalic acid is the preferred agent, there are significant potential downstream impacts. Impacts include: (1) Degraded evaporator operation; (2) Resultant oxalate precipitates taking away critically needed operating volume; and (3) Eventual creation of significant volumes of additional feed to salt processing. As an alternative to dealing with the downstream impacts, oxalate decomposition using variations of ozone based Advanced Oxidation Process (AOP) were investigated. In general AOPs use ozone or peroxide and a catalyst to create hydroxyl radicals. Hydroxyl radicals have among the highest oxidation potentials, and are commonly used to decompose organics. Although oxalate is considered among the most difficult organic to decompose, the ability of hydroxyl radicals to decompose oxalate is considered to …

Agreement Between Local and Global Measurements of the London Penetration Depth (open access)

Agreement Between Local and Global Measurements of the London Penetration Depth

Recent measurements of the superconducting penetration depth in Ba(Fe{sub 1-x}Co{sub x}){sub 2}As{sub 2} appeared to disagree on the magnitude and curvature of {delta}{lambda}{sub ab}(T), even near optimal doping. These measurements were carried out on different samples grown by different groups. To understand the discrepancy, we use scanning SQUID susceptometry and a tunnel diode resonator to measure the penetration depth in a single sample. The penetration depth observed by the two techniques is identical with no adjustments. We conclude that any discrepancies arise from differences between samples, either in growth or crystal preparation.

Air Passenger Screening: Transportation Security Administration Needs to Improve Complaint Processes (open access)

Air Passenger Screening: Transportation Security Administration Needs to Improve Complaint Processes

Testimony issued by the Government Accountability Office with an abstract that begins "In summary, TSA receives thousands of air passenger screening complaints through five central mechanisms, but does not have an agencywide policy, consistent processes, or a focal point to guide receipt and use of such information. Also, while the agency has several methods to inform passengers about its complaint processes, it does not have an agencywide policy or mechanism to ensure consistent use of these methods among commercial airports. In addition, TSA's complaint resolution processes do not fully conform to standards of independence to ensure that these processes are fair, impartial, and credible, but the agency is taking steps to improve independence. To address these issues, we made four recommendations to TSA with which the agency concurred, and it indicated actions it is taking in response. Finally, TSA officials stated that the agency is undertaking efforts to focus its resources and improve the passenger experience at security checkpoints by applying new intelligence-driven, risk-based screening procedures, including expanding its Pre✓™ program. TSA plans to have this program in place at 35 airports by the end of the calendar year and estimates that it has screened more than 4 million passengers …

Airborne Electronic Attack: Achieving Mission Objectives Depends on Overcoming Acquisition Challenges (open access)

Airborne Electronic Attack: Achieving Mission Objectives Depends on Overcoming Acquisition Challenges

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense’s (DOD) evolving strategy for meeting airborne electronic attack requirements centers on acquiring a family of systems, including traditional fixed wing aircraft, low observable aircraft, unmanned aerial systems, and related mission systems and weapons. DOD analyses dating back a decade have identified capability gaps and provided a basis for service investments, but budget realities and lessons learned from operations in Iraq and Afghanistan have driven changes in strategic direction and program content. Most notably, DOD canceled some acquisitions, after which the services revised their operating concepts for airborne electronic attack. These decisions saved money, allowing DOD to fund other priorities, but reduced the planned level of synergy among systems during operations. As acquisition plans have evolved, capability limitations and sustainment challenges facing existing systems have grown, prompting the department to invest in system improvements to mitigate shortfalls."

Calibrating Curved Crystals Used for Plasma Spectroscopy

The throughput and resolving power of an X-ray spectrometer that uses a curved crystal as the diffraction element is determined primarily by the crystal X-ray reflectivity properties. This poster presents a measurement technique for these crystal parameters using a simple diode source to produce a narrow spectral band. The results from measurements on concave elliptical polyethylene terephthalate (PET) crystals and convex potassium acid phthalate (KAP) crystals show large variations in the key parameters compared to those from the flat crystal.

Catalyzed Ceramic Burner Material (open access)

Catalyzed Ceramic Burner Material

Catalyzed combustion offers the advantages of increased fuel efficiency, decreased emissions (both NOx and CO), and an expanded operating range. These performance improvements are related to the ability of the catalyst to stabilize a flame at or within the burner media and to combust fuel at much lower temperatures. This technology has a diverse set of applications in industrial and commercial heating, including boilers for the paper, food and chemical industries. However, wide spread adoption of catalyzed combustion has been limited by the high cost of precious metals needed for the catalyst materials. The primary objective of this project was the development of an innovative catalyzed burner media for commercial and small industrial boiler applications that drastically reduce the unit cost of the catalyzed media without sacrificing the benefits associated with catalyzed combustion. The scope of this program was to identify both the optimum substrate material as well as the best performing catalyst construction to meet or exceed industry standards for durability, cost, energy efficiency, and emissions. It was anticipated that commercial implementation of this technology would result in significant energy savings and reduced emissions. Based on demonstrated achievements, there is a potential to reduce NOx emissions by 40,000 TPY …
