Sorptive Polymers and Photopatterned Films for Gas Phase Chemical Microsensors and Arrays

Description: Chemical sensors using interactive sorptive materials typically involve a ''two-step'' response mechanism. While the sorptive material collects and concentrates gas phase molecules, the device on which it has been applied transduces the presence of these sorbed molecules into an analytical signal. Usually, the sorptive material is a thin film and the device is a microfabricated structure, although other configurations exist. The film of a sorptive material is often referred to as the ''selectiv… more

Microstructural Origins of Dynamic Fracture in Ductile Metals

Description: From the formation of microscopic cracks in the fuel pipe liner of the space shuttle to the safety of roadway bridges, the fracture of materials has enormous implications throughout our society. The ability to assess and design safe engineering structures requires a detailed knowledge of this failure process. The fracture process depends on both the loading history and the detailed microscopic structure (microstructure) of the material. Weak points, such as inclusions and grain boundary junctio… more

Shear Localization and Fracture in Shocked Metals

Description: Metals are used in structural engineering applications because they can yield and deform before they break. However, under certain conditions of dynamic loading, metals can fail prematurely. This behavior is often associated with shear localization phenomena, with a shear band acting as a precursor to crack formation. These phenomena have been observed in metals for some time, however modeling this behavior in a continuum simulation code has met with very limited success. We are pursuing a seri… more

Novel Concepts for Damage-Resistant Alloys in Next Generation Nuclear Power Systems - Final Report , Project 99-0280

Description: The discovery of a damage-resistant alloy based on Hf solute additions to a low-carbon 316SS is the highlight of the Phase II research. This damage resistance is supported by characterization of radiation-induced microstructures and microchemistries along with measurements of environmental cracking. The addition of Hf to a low-carbon 316SS reduced the detrimental impact of radiation by changing the distribution of Hf. Pt additions reduced the impact of radiation on grain boundary segregation bu… more

Modeling and Characterization of Recompressed Damaged Materials

Description: Ductile metals subjected to shock loading can develop internal damage through nucleation growth and coalescence of voids. The extent of damage can range from a well-defined spall plane induced by light shocks to more widespread damage caused by strong shocks. Because damage materials are often part of a dynamic system, significant additional deformation can occur in extensively damaged materials. To represent material behavior in simulation codes for stockpile stewardship calculations, both the… more

Geochemical Factors Affecting the Behavior of Antimony, Cobalt, Europium, Technetium, and Uranium in Vadose Zone Sediments

Description: In developing the Field Investigation Report (FIR) for the Waste Management Area (WMA) S-SX at the Hanford Site, cesium-137 was the only gamma emitting radionuclide of concern (Knepp 2002). However, in WMA B-BX-BY, the spectral gamma logging data identify seven gamma emitting radionuclides, cesium-137, antimony-125, europium-152 and -154, cobalt-60, uranium-235 and -238 (DOE-GJPO 1998). The geochemical behaviors of several of these radionuclides, antimony-125 and the two europium isotopes, have… more

Final Report: Deconvolution of Adaptive Optics Images of Titan, Neptune, and Uranus

Description: This project involved images of Titan, Neptune, and Uranus obtained using the 10-meter W.M. Keck II Telescope and its adaptive optics system. An adaptive optics system corrects for turbulence in the Earth's atmosphere by sampling the wavefront and applying a correction based on the distortion measured for a known source within the same isoplanatic patch as the science target (for example, a point source such as a star). Adaptive optics can achieve a 10-fold increase in resolution over that obta… more

The Hanford Site 1000-Year Cap Design Test

Description: Surface barrier or capping technology is needed to isolate buried wastes. A successful cap must prevent the intrusion of plants, animals, and man into the underlying waste, minimize wind and water erosion, require minimal maintenance, and limit water intrusion to near-zero amounts. For some sites where wastes are long-lived, caps should potentially last a thousand years or more. At the U.S. Department of Energy (DOE) Hanford Site in Washington State, a surface cap with a 1000-year design life w… more
