An ultrahigh molecular weight polymer, such as ultrahigh molecular weight polyisobutylene, is used as an additive to enhance the coating properties of a solvent. The polyisobutylene has a molecular weight of at least 2.5-3.0 million daltons, preferably greater than about 6 daltons, and is provided in a preferred concentration of 0.05 to 0.3%. The solvent can be a medicinal grade mineral oil. Other suitable solvents include hydrocarbon oil and low viscosity, synthetic compositions. In all cases, the coating properties of the solvent are greatly enhanced by the addition of ultrahigh molecular weight polyisobutylene. In another aspect of the invention, ultrahigh molecular weight polyisobutylene is used as an additive to enhance the viscoelasticity of a mineral oil based sunscreen formulation. In still another aspect of the invention, the fibers of a fabric material are coated with an ultrahigh molecular weight polymer to greatly strengthen the fabric. Other applications include improved automobile polishes and paint sealers, rust removers, and leather treatments.

Apparatus for producing nano-particles comprises a furnace defining a vapor region therein. A precipitation conduit having an inlet end and an outlet end is positioned with respect to the furnace so that the inlet end is open to the vapor region. A quench fluid port positioned within the precipitation conduit provides a quench fluid stream to the precipitation conduit to precipitate nano-particles within the precipitation conduit. A product collection apparatus connected to the outlet end of the precipitation conduit collects the nano-particles produced within the precipitation conduit.

A method and composition for improving the mechanical efficiency of a engine is provided. Ultra-high molecular weight polyisobutylene (PIB) added to the fuel changes the momentary mechanical properties of the fuel during induction. The additive provides a more uniform spray droplet size, increases the extensional viscosity of the fuel, and adapts other physical properties, under induction conditions.
摘要:
A method for producing purified MoO.sub.3 from MoS.sub.2. MoS.sub.2 is initially oxidized to generate an impure MoO.sub.3 product containing metallic contaminants and molybdenum sub-oxides. This product is then slurried with a primary water supply to yield a first slurry in which part of the contaminants are dissolved. Preferred slurry temperatures are 25.degree.-97.degree. C. The resulting solid intermediate MoO.sub.3 product is removed from the slurry leaving the dissolved contaminants. Next, the intermediate MoO.sub.3 product is slurried with a secondary water supply to yield a second slurry in which the remaining contaminants are dissolved. Second slurry temperatures of 150.degree.-250.degree. C. are employed in the presence of an oxygen-containing gas. These conditions oxidize molybdenum sub-oxides to yield MoO.sub.3. The resulting purified solid MoO.sub.3 product is then removed from the second slurry. This process is highly efficient and avoids using liquid reagents other than water (including acids).

摘要:
Apparatus for producing nano-particles according to the present invention may comprise a furnace defining a vapor region therein. A precipitation conduit having an inlet end and an outlet end is positioned with respect to the furnace so that the inlet end is open to the vapor region. A quench fluid supply apparatus supplies quench fluid in a gas state and quench fluid in a liquid state. A quench fluid port positioned within the precipitation conduit is fluidically connected to the quench fluid supply apparatus so that an inlet to the quench fluid port receives quench fluid in the gas state and quench fluid in the liquid state. The quench fluid port provides a quench fluid stream to the precipitation conduit to precipitate nano-particles within the precipitation conduit. A product collection apparatus connected to the outlet end of the precipitation conduit collects the nano-particles produced within the precipitation conduit.
摘要:
Molybdenum oxide nano-particles. The nano-particles may be made by vaporizing the precursor material to produce a vapor; directing the vapor into an isolation chamber; contacting the vapor contained in the isolation chamber with a quench fluid stream to precipitate nano-particles; and removing the nano-particles from the isolation chamber.
