Abstract: The invention provides stabilized, biocompatible gold nanoparticles that are stabilized with material from soy or lentil plant material or a reactive extract thereof of the plant material. The gold nanoparticles of the invention can be fabricated with an environmentally friendly method for making biocompatible stabilized gold nanoparticles. The nanoparticles can be introduced in vivo to conduct enhanced imaging. The nanoparticles can also be introduced in vivo to conduct therapy.

Abstract: An internal channel in a metal body for use in applications where internal fluid flow within a metal body is desired, as in a heat exchanger. The internal channel is formed in the metal body by frictionally stirring with a pin plunged into the metal body, and traversing the metal body with the pin.

Abstract: Corrosion resistance of metallic components such as stainless steel components of vehicles, and especially aluminum-based components of aircraft, is enhanced by application of an e-coat paint or primer which is enhanced by incorporation of cerium ions into the e-coat electrolytic bath. The resulting overall coating includes a cerium-based layer under a cerium-enhanced e-coat paint or primer layer.

Abstract: A method for forming a miniaturized shaped component. Bulk superplastic material is contacted with a flat rotating surface of a rotating tool to frictionally heat the bulk superplastic material with the bulk superplastic material positioned between the flat rotating surface of the tool and a microfabricated tool die. The bulk superplastic material is forced into the microfabricated die once the bulk superplastic material is heated to a temperature between a glass transition temperature and a crystallization temperature.

Abstract: A method of determining providing analytical services, particularly trace element analysis is disclosed. The method includes supplying a sample container to a customer, having the customer return the sample container with the sample inside the container, and analyzing the sample by neutron activation analysis without opening the sample container.

Abstract: Improved polymeric orthopaedic compositions are disclosed wherein sized, functional fibers are incorporated into a physiologically acceptable matrix. The compositions of the invention can be fabricated in the form of particulate powders adapted for reinforcment of bone cements, continuous media for such cements, and orthopaedic implant coatings. A complete implant attachment system is also provided, made up of a fiber reinforced implant coating, and a compatible fiber-reinforced cement. In preferred forms, the fibers have a layer of sizing thereover which is chemically joined both to the surface of the fibers and to the surrounding matrix, and the fibers are present at a level of at least about 6 volume percent. If desired, sized radiopaque particles may be incorporated into the compositions of the invention. The fibers are advantageously polymeric in nature and of intermediate stiffness, whereas the matrix fraction is preferably polymethylmethacrylate.

Abstract: Process for preparing a radionuclide generator for producing Tc-99m or Re-188. A clear solution containing a metallic cation and an anion comprising W-188 or Mo-99 is provided. The metallic cation is present in the solution as a dissolved complex of the metallic cation and a complexing agent and/or the anion being present in the solution as a dissolved complex of the anion and a complexing agent. The dissolved complex(es) are decomposed to form a slurry containing a precipitate of the metallic cation and the anion. The precipitate is transferred to an elutable container of a radionuclide generator.
