    Abstract: A novel vanadium phosphorus oxide (VPO) catalyst obtained using a novel VPO preparation technique. The VPO composition is characterized by the powder x-ray diffraction pattern given in Table 1. The novel VPO preparation technique consists of 1) dissolving vanadium and phosphorus compositions in a solvent such as water to form a solution, 2) forming an aerosol from the resulting solution, 3) heating the aerosol to afford a VPO precursor, and 4) activating the VPO precursor to give the VPO catalyst. The activated VPO catalyst demonstrates selective oxidation activity for hydrocarbons and good conversion and selectivity for the oxidation of butane to maleic anhydride.

    Abstract: The present invention is the formation of solid polymer layers under vacuum. More specifically, the present invention is the use of "standard" polymer layer-making equipment that is generally used in an atmospheric environment in a vacuum, and degassing the monomer material prior to injection into the vacuum. Additional layers of polymer or metal or oxide may be vacuum deposited onto solid polymer layers. Formation of polymer layers under a vacuum improves material and surface characteristics, and subsequent quality of bonding to additional layers. Further advantages include use of less to no photoinitiator for curing, faster curing, fewer impurities in the polymer electrolyte, as well as improvement in material properties including no trapped gas resulting in greater density, and reduced monomer wetting angle that facilitates spreading of the monomer and provides a smoother finished surface.

    Abstract: The present invention includes a method of treating solid earthen material having volatile, semi-volatile, and non-volatile contaminants. Six electrodes are inserted into a region of earthen material to be treated in a substantially equilateral hexagonal arrangement. Six phases of voltages are applied to corresponding electrodes. The voltages are adjusted within a first range of voltages to create multiple current paths between pairs of the electrodes. The current paths are evenly distributed throughout the region defined by the electrodes and therefore uniformly heat the region. The region of earthen material is heated to a temperature sufficient to substantially remove volatile and semi-volatile contaminants by promoting microbial action. This temperature is less than a melting temperature of the earthen material.

    Abstract: Apparatus for improving properties of a solid material by providing shock waves therein. A laser oscillator (10a) provides a plurality of pulses (112) of coherent radiation. The leading edge of each pulse is sharpened either by a metal foil (18) or by phase conjugation reflection means (18a, 18e) including a stimulated Brillouin scattering cell (18d, 18e) and optionally a Faraday isolator (18b). Each pulse is directed onto an amplifier (123) comprising first and second laser amplifier rods (23a, 23b) in series. At least a major portion of the radiation (112) amplified by the first amplifier rod (23a) is directed to the second amplifier rod (23b), where it is amplified and then directed to a surface of the solid material. Substantially uniform spatial amplitude is achieved in the radiation (112) in at least one of these ways: a pair of flashlamps (70, 71) are included with each laser amplifier rod (23a, 23b) for pumping the rod; the axis of each flashlamp (70, 71) and the axis of the first rod (23a) are substantially parallel to each other and substantially in the same (first) plane; and a (second) plane containing the axis of the second rod (23b) and the parallel axes of its associated flashlamps (70, 71) is substantially perpendicular to the first plane; and/or the oscillator (10c) provides a beam of unpolarized coherent radiation (12T) in which the spatial amplitude pattern of each succeeding pulse is substantially a mirror image of the pattern in the pulse that preceded it, or is rotated about its axis by a predetermined smaller angle from the pattern in the pulse that preceded it.

    Abstract: A photochromic composition for incorporation into a light-transmitting polymer is described. Silver-containing crystallites of silver halide or non-halide silver complex are capped with an organic capping group using multivalent metal ions integrated into the surface of the silver-containing crystallite to provide crystallite surface sites that provide a handle between the organic capping group and the silver-containing crystallites. The size of the capped silver-containing crystallites are less than about 1000 Å. A reverse micelle technique is used to control the size of the silver-containing crystallite while integrating the multivalent ions and bonding the organic capping group. The capped crystallites are soluble in organic solvents and, as such, are readily incorporated into a polymer matrix.

    Abstract: The present invention is directed to a water-resistant, aqueous base-dispersible article which comprises a pulp-filled binder, one of which is an ethylenically unsaturated carboxylated (e.g. acrylic) polymer soluble in base, the other of which is water-resistant. Accordingly, the pulp can be water-resistant while the binder is base-dispersible or the converse can be true. Cellulosic and polymeric pulp are ideally suited for filling a base-soluble acrylic polymer. Water-soluble resins can be incorporated into the article for controlling the properties for special purposes. The method for forming such an article comprises yet another aspect of the present invention.

    Abstract: Processes are disclosed for producing lactic acid, esters of lactic acid, acrylic acid, and esters of acrylic acid, primarily from fermentable carbohydrate materials. An overall process for producing esters of acrylic acid comprises: a) fermenting carbohydrate material with a lactic-acid-forming organism in the presence of NH3 to produce ammonium lactate; b) combining the ammonium lactate with an alcohol; c) combining the ammonium lactate and alcohol with an effective catalyzing amount of gaseous CO2 to catalytically esterify the ammonium lactate and alcohol into a lactic acid ester containing solution; d) recovering purified lactic acid ester; and e) vaporizing the lactic acid ester and passing it through a solid catalyst bed comprised of an effective catalyzing amount of crystalline hydrated and partially calcined calcium sulfate to catalytically convert lactic acid ester into an acrylic acid ester. Step 'd' would be useful in a process for making low-cost, purified lactic acid. Similarly, step 'e' would be useful in a process for making low cost, purified acrylic acid.

    Abstract: Thermally-reversible polymer compositions are obtained by reacting compounds with isocyanate and labile-hydrogen functionality. High-performance characteristics are incorporated into the polymer by using polyimide, aromatic polycarbonate, aromatic polyester, polyphenylene sulfide, and poly(parabanic acid) oligomers. Low-temperature flexibility and toughness are imparted to the polymers by using prepolymers such as polycaprolactone diols, polytetramethylene ether glycols and polyaliphatic carbonate diols. Ionic bonding and liquid-crystal functionality may also be incorporated into the compositions. The compositions are useful as hot-melt adhesives, coatings, and moldings and in injection reaction molding applications and composite and laminate fabrication.

    Abstract: The amount of ionizing radiation to which a thermoluminescent material has been exposed is determined by first cooling the thermoluminescent material to a cryogenic temperature. The thermoluminescent material is then optically stimulated by exposure to ultraviolet light. Visible light emitted by the thermoluminescent material as it is allowed to warm up to room temperature is detected and counted. The thermoluminescent material may be annealed by exposure to ultraviolet light.
