Mound Laboratory Progress Report for January 1961

Description: Work was begun to determine the physical properties of mica-filled diallyl phthalate. Both the impact and tensile strength values compared favorably wlth asbestos-filled DAP formulatlons. The tensile values compared with the upper limit tensile strength values for asbestos-filled formulations. Adiprene-ferric acetyl acetonate-polyol systems were developed as adhesives and their properties studied. Sources of kilogram quantities of Th/sup 2//sup 3//sup 0/ were investigated. The samples were anal… more

Effect of Lamination Conditions on the Gas Permeability and Adhesion Strength of Green Ceramic Tapes

Description: The gas permeability and adhesion strength of laminated green ceramic tapes were determined for samples comprised of barium titanate as the dielectric, and poly(vinyl butyral) and dioctyl phthalate as the main components of the binder mixture. The green tapes were laminated for times of 2-10 min, pressures of 1.8-7 MPa, and temperatures of 35-85C. The adhesion strength, which was measured by a peel test, increased with increasing lamination time, temperature, and pressure. The permeability, wh… more

Integrated analysis of breast cancer cell lines reveals unique signaling pathways

Description: Cancer is a heterogeneous disease resulting from the accumulation of genetic defects that negatively impact control of cell division, motility, adhesion and apoptosis. Deregulation in signaling along the EGFR-MAPK pathway is common in breast cancer, though the manner in which deregulation occurs varies between both individuals and cancer subtypes. We were interested in identifying subnetworks within the EGFR-MAPK pathway that are similarly deregulated across subsets of breast cancers. To that e… more

Development of Niobium Diffusion Barriers for Aluminum-Clad Uranium Alloy Fuel Elements

Description: S>Nickel was used as a diffusion barrier for Al-clad uranium alloy fuel elements, operating at 650 nif- F in organiccooled reactors. Advanced organic-moderated reactor (AOMR) concepts include operating temperatures up to 850 nif- F. Since the interdiffusion of Al --Ni is 150 times faster at 850 nif- F than at 650 nif- F, an alternate diffusion barrier is required. Subsequent studies resuited in the selection of niobium. Several techniques for bonding niobium to the U--10 Mo fuel were investigat… more

Development of Clad Ceramic Fuel Plates by Spray-Coating Techniques. Final Report, Phase I

Description: Activities in a program to develop techniques of plasma spraying clad plate-type UO/sub 2/ fuel elements are reported. The investigation was also directed toward determining the limitations of the process as applied to fuel element fabrication. UO/sub 2/ powder coatings having densities of 90% theoretical were produced. At conditions required for spraying plates, densities of 86% appear to be practical. The rate and efficiency of UO/sub 2/ coating deposition were also determined for various spr… more

Processing and properties of chromate-free conversion coatings on aluminum

Description: A conversion coating method has been developed based on precipitation of Li{sub 2}[Al{sub 2}(OH){sub 6}]{sub 2}{center_dot}CO{sub 3}{center_dot}3H{sub 2}O from alkaline lithium salt solutions. The process is procedurally similar to chromate conversion coating but does not use or produce hazardous chemicals. The coating that forms is polycrystalline, continuous and conformal. The coating meets the MIL-C-5541E corrosion resistance, electrical contact resistance and paint adhesion requirements for… more

Composite Cathode for High-Power Density Solid Oxide Fuel Cells

Description: Reduction of solid oxide fuel cell (SOFC) operating temperature will play a key role in reducing the stack cost by allowing the use of low-cost metallic interconnects and new approaches to sealing, while making applications such as transportation more feasible. Reported results for anode-supported SOFCs show that cathode polarization resistance is the primary barrier to achieving high power densities at operating temperatures of 700 C and lower. This project aims to identify and develop composi… more

Novel microorganism for selective separation of coal from ash and pyrite. Seventh quarterly technical progress report, April 1, 1995--June 30, 1995

Description: The selective separation of pyrite and ash-forming minerals from coal can be accomplished by flotation, agglomeration and selective flocculation. The methods currently used for selective flocculation of coals include addition of natural or synthetic polymeric flocculants along with precise pH control. In some cases, these flocculants are nonselective or work imperfectly. It is known that many highly charged planktonic algae and bacteria will adhere to certain solid surfaces if the charge or hyd… more

[Design of gas and electric rotary furnaces for the glass industry]. Quarterly progress report, September 20--December 20, 1997

Description: The authors have continually stressed that the two most critical material parameters for the success of the rotary furnace are the hearth plate and the molding release powder. Both of these issues have been solidly addressed in this quarter. They have tested the three best candidates for hearth plate material this quarter. Although they had to use the in-house gas furnaces for the testing, one of the materials combines the best heating efficiency with the least sticking tendency. This material … more

The effect of stress on the nanomechanical properties of Au surfaces

Description: Stress in thin films plays a critical role in many technologically important areas. The role is a beneficial one in strained layer superlattices where semiconductor electrical and optical properties can be tailored with film stress. On the negative side, residual stress in thin-film interconnects in microelectronics can lead to cracking and delamination. In spite of their importance, however, surface and thin-film stresses are difficult to measure and control, especially on a local level. In re… more

Interfacial adhesion at the molecular level

Description: Interfacial adhesion is of extraordinary technological importance and has long been of intense scientific interest. However, the study of the adhesive bond and its failure is made difficult by the complexity of the interfacial interaction and the problems involved with establishing carefully characterized and controlled interfacial surfaces and that of quantitatively evaluating the bonding after its formation. In the present work, we outline the results of studies using Interfacial Force Micros… more

Optical techniques for determining dynamic material properties

Description: Miniature plates are laser-launched with a 10-Joule Nd:YAG for one-dimensional (1-D) impacts on to target materials much like gas gun experiments and explosive plane wave plate launch. By making the experiments small, flyer plates (3 mm diameter x 50 micron thick) and targets (10 mm diameter x 200 micron thick), 1-D impact experiments can be performed in a standard laser-optical laboratory with minimum confinement and collateral damage. The laser-launched plates do not require the traditional s… more
