REACTION MECHANISMS OF MAGNESIUM SILICATES WITH CARBON DIOXIDE IN MICROWAVE FIELDS

Description: The objective of the investigation was to determine whether microwave fields would enhance the reactions of CO{sub 2} with silicates that are relevant to the sequestration of carbon dioxide. Three sets of experiments were conducted. (1) Serpentine and CO{sub 2} were reacted directly at one atmosphere pressure in a microwave furnace. Little reaction was observed. (2) Serpentine was dehydroxylated in a microwave furnace. The reaction was rapid, reaching completion in less than 30 minutes. A detai… more

Performance Assessment/Composite Analysis Modeling to Support a Holistic Strategy for the Closure of F Area, a Large Nuclear Complex at the Savannah River Site

Description: A performance-based approach is being used at the Savannah River Site to close the F area Complex. F Area consists of a number of large industrial facilities including plutonium separations, uranium fuel fabrication, tanks for storing high level waste and a number of smaller operations. A major part of the overall closure strategy is the use of techniques derived from the Performance Assessment and Composite Analysis requirements for low level waste disposal at DOE sites. This process will prov… more

Isosurface Computation Made Simple: Hardware acceleration,Adaptive Refinement and tetrahedral Stripping

Description: This paper presents a simple approach for rendering isosurfaces of a scalar field. Using the vertex programming capability of commodity graphics cards, we transfer the cost of computing an isosurface from the Central Processing Unit (CPU), running the main application, to the Graphics Processing Unit (GPU), rendering the images. We consider a tetrahedral decomposition of the domain and draw one quadrangle (quad) primitive per tetrahedron. A vertex program transforms the quad into the piece of i… more

In-Situ TEM Observations of Interface Sliding and Migration in a Refined Lamellar TiAl Alloy

Description: The stability of lamellar interfaces in lamellar TiAl by straining at ambient temperatures has been investigated using in-situ straining techniques performed in a transmission electron microscope in order to obtain direct evidence to support the previously proposed creep mechanisms in refined lamellar TiAl based upon the interface sliding in association with the cooperative motion of interfacial dislocations. The results have revealed that both sliding and migration of lamellar interfaces can t… more

Accelerated Carbonate Dissolution as a CO2 Separation and Sequestration Strategy

Description: We have proposed a technique that could reduce CO{sub 2} emissions from near coastal fossil-fuel power plants using existing power plant cooling water flow rates (Rau and Caldeira, 1999; Caldeira and Rau, 2000). Preliminary cost estimates are as low as $68 per tonne C sequestered, as compared to > $170 per tonne C estimated for other approaches to CO{sub 2} separation with geologic or deep-ocean storage. Engineers at McDermott Technologies, Inc., have independently estimated the cost of our … more

Screening of Maritime Containers to Intercept Weapons of Mass Destruction

Description: The goal of our research was to address the problem of detection of weapons of mass destruction (WMD) materials within containers in common use on commercial cargo trafficking. LLNL has created an experimental test bed for researching potential solutions using (among other techniques) active interrogation with neutrons. Experiments and computational modeling were used to determine the effectiveness of the technique. Chemical weapons materials and high explosives can be detected using neutron ac… more

A Tribute to George F. Pinder

Description: In the fall of 2001 a Special Session was convened at the Fall Meeting of the American Geophysical Union as a tribute to George F. Pinder's contributions to groundwater modeling in the last thirty-five years. At a subsequent meeting of the editorial board of Advances in Water Resources (AWR), we reflected on George's contributions to the field of groundwater hydrology and his particular contributions to AWR, which he co-founded in 1977 with Carlos A. Brebbia. It was at this meeting that the see… more

Microstructural Origins of Dynamic Fracture in Ductile Metals

Description: Dynamic fracture is a material failure process at high strain-rates. Here, we limit our discussion to spallation fracture during shock wave loading. When a compressive shock wave reflects from a free surface, internal states of tension are created. If this tension exceeds the rupture strength of the material, it fails by nucleating and growing microscopic voids in ductile metals and cracks in brittle solids. This effect, known as spallation, was reported by Hopkinson in 1872 [1]. Rinehart and P… more

Computational Methods for Collisional Plasma Physics

Description: Modeling the high density, high temperature plasmas produced by intense laser or particle beams requires accurate simulation of a large range of plasma collisionality. Current simulation algorithms accurately and efficiently model collisionless and collision-dominated plasmas. The important parameter regime between these extremes, semi-collisional plasmas, has been inadequately addressed to date. LLNL efforts to understand and harness high energy-density physics phenomena for stockpile stewards… more

PROCEEDINGS OF RIKEN BNL RESEARCH CENTER WORKSHOP, VOLUME 57, HIGH PT PHYSICS AT RHIC, DECEMBER 2-6, 2003

Description: The AuAu, dAu, and pp collision modes of the RHIC collider at BNL have led to the publication of exciting high p{perpendicular} particle production data. There have also been two physics runs with polarized protons, and preliminary results on the double-spin asymmetry for pion production had been presented very recently. The ontological questions behind these measurements are fascinating: Did RHIC collisions create a Quark-Gluon-Plasma phase and did they verify the Color Glass Condensate as the… more
