Abstract:
About 1/2 cc of a sterile composition (5) dropped into the rotor drive air feed line (11) of a dental handpiece (10) while holding the handpiece upside down protects and lubricates the handpiece bearings and turbine during the subsequent auto-clave sterilization process. An additional dosage inserted into the bur hole after the auto-clave process further lubricates the handpiece and inhibits rust from forming on the handpiece bearings and turbine during use. The pre-sterilization dosage and post-sterilization dosage of measured amounts may be separately packaged in disposable capsules (20, 30). The composition (5) is made by heat mixing until sterile about 10 % by volume of a sterile solution of Power-UpTM NNL-690, which is a liquid hydrocarbon boundary lubricant and corrosion inhibitor, with 90 % by volume of pharmaceutical grade mineral oil.

Abstract:
Methods for preparing colloidal metal nanoparticles, in which a solution of reductant is added to a boiling solution of a source of metal ion coincidentally with seed colloids are described, including a method using colloidal gold nanoparticle seeds, a gold ion source (HAuCl4), and sodium citrate (reductant). Methods for preparing colloidal metal nanoparticles, in which seed colloids are added to a solution of reductant mixed with a solution containing a source of metal ions are also described, including a method in which the seeds are colloidal gold nanoparticles, the source of gold ions is HAuCl4, and the reductant is NH2OH. Methods for preparing colloidal metal nanoparticles, in which the seed colloids are the result of the application of the previous methods, and the source of metal ions and the reductant are added to the seed colloids in an iterative fashion, are also described. The colloidal metal nanoparticles that are the product of the application of the above methods are also described. Certain colloidal metal nanoparticles have a major axis standard deviation of about 14 % or less, a minor axis standard deviation of about 14 % or less, and an ellipticity 1.5.
Abstract:
Provided herein is a barium sulfate-containing catalyst carrier. The catalyst carrier is useful for supporting an exhaust gas purification catalyst, such as a three way conversion catalyst. In an embodiment, the carrier comprises BaSO4/thermally stable alumina. Further provided is a process for preparing the catalyst carrier, with or without precious metals, comprising treating a barium oxide/alumina or barium carbonate/alumina with a stoichiometric amount of sulfuric acid (H2SO4), thus forming BaSO4/alumina in situ in good yield and at low cost.
