Abstract: The present invention relates to an electrospinning device. The electrospinning device may apply the force of a supersonic flow acting at a predetermined angle with respect to an electrostatic force on a fiber discharged from an electrospinning nozzle to cause shearing stress on the fiber, thereby providing fibers having a very small diameter and collecting fibers having a finer diameter. Also, the electrospinning device may collect finer and more uniform fibers by adjusting the relative positions of the electrospinning nozzle for discharging the fiber and a gas spray nozzle for spraying a gas.

Abstract: A plant wound dressing composed of a blend of polymers and methods for their manufacture and use are described.

Abstract: Provided are construction products with a density in the range from about 10 pcf to about 125 pcf and comprising an inorganic filler cross-linked in a polyurethane matrix produced by an exothermic reaction between at least one alcohol having two or more reactive hydroxyl groups per molecule and at least one isocyanate having more than one reactive isocyanate group per molecule, wherein a molar ratio of the alcohol to the isocyanate is in the range from 0.25:1 to 5:1. Methods for making the products are provided as well.

Abstract: A mixing assembly includes a main flow conduit having an inlet end and an opposite outlet, a source of pressurized air at the inlet end, a container of stucco in fluid communication with the flow conduit, and a source of water in fluid communication with the flow conduit between the outlet and the container. The pressurized air draws stucco from the container into the flow conduit, and also draws water into the flow conduit to form an atomized slurry.

Abstract: A device including a micro component having an external surface and a permeable nanofiber covering on at least a portion of the external surface of the micro component. A cooled micro component system further includes a droplet spray system for spraying liquid droplets onto the nanofiber covering to cool the micro component. In an example method for cooling a micro component, droplet spray is directed onto a nanofiber covering that covers at least a portion of the micro component. The directing is controlled to permit efficient spreading and evaporation of liquid permeating the nanofiber covering. In example embodiments nanofibers of the permeable nanofiber covering are metalized to provide a rougher surface (e.g., a nano-textured metal layer).

Abstract: Disclosed herein is a single pot process for producing biodiesel and the product thereof, using non-edible oil sources containing free fatty acid. The process comprises esterification and transesterification of non-edible vegetable oil sources containing free fatty acids in a single pot employing a water scavenger or a water adsorbent or a mixture thereof.

Abstract: This invention relates to a catalyst composition capable of effecting selective oligomerisation of olefins contained in cracked refinery distillate streams, comprising of olefins, aromatics, paraffins and cycloparaffins. The catalyst composition gives very high conversion of olefins to poly olefins, which after distillation and stabilization by hydrogenation affords lubricating oil base stocks. The catalyst composition comprises of an aluminum halide and a transition metal alkoxide belonging to group IVB.

Abstract: A process for the preparation of an inert oxide supported metal halide organo aluminium compound catalyst. The catalyst is obtained by reacting an activated support having surface hydroxyl groups with aluminium chloride selected from aluminium chloride solution and aluminium chloride vapors. A solution of an aluminium alkyl is added to the reacted support. The solvent is removed and the reacted support is dried.

Abstract: A process for the preparation of heterogeneous zirconium based catalyst for polymerization of alpha-olefins to super high molecular weight poly (alpha-olefins). The process comprises in mixing zirconium alcholate or phenolate with anhydrous magnesium chloride in the presence of a solvent. The mixture is heated, then cooled and an organoaluminum compound is added. Optionally, an electron donor compound is added and heated to obtain a black slurry, which is cooled and then washed with a hydrocarbon diluent.

Abstract: A process for the oligomerization and co-oligomerization of alpha olefins by subjecting olefins to the step of oligomerization in the presence of a supported aluminum chloride catalyst and an organoaluminum compound as a promoter. The catalyst is separated and the reaction product is subjected to the step of fractional distillation for removal of the solvent. The oligomers are further fractionated to obtain poly alpha olefins.

Abstract: A catalyst composition for use in oligomerization of olefins contained in refinery distillate streams including paraffins, naphthenes, and aromatics therein, the catalyst consisting of a first constituent which is at least one aluminum halide; and a second constituent which is at least one alkoxide of a transition metal of Group IVB of the Periodic Table and which has a general formula:M(OR).sub.4,where M is selected from the group consisting of metals of Group IVB of the Periodic Table and R is one of (a) an alkyl group having from 1-12 carbon atoms or (b) an alkylaryl group having an alkyl chain having from 1-12 carbon atoms.

Abstract: A process for the preparation of oligomers which are used in synthetic lubricant base stocks. The oligomers are prepared by contacting a mixture of linear olefins and n-paraffins contained in cracked refinery streams having 6 to 24 carbon atoms with activated Y-zeolites. The oligomers and unreacted monomers are subjected to the step of hydrogenation and the lower saturated paraffins are separated therefrom to produce synthetic lubricant base stock.
