Thermosetting adhesive compositions for use in e.g., particleboard or fiberboard, wherein the compositions comprise a blend of a protein-based component and a polymeric quaternary amine cure accelerant, can provide the fast tack-building and curing, as well as ultimately good bonding characteristics normally associated with synthetic resin compositions. Preferably, the polymeric quaternary amine cure accelerant is the reaction product of a polyamidoamine and epichlorohydrin.

A molecular plasma discharge deposition method for depositing colloidal suspensions of biomaterials such as amino acids or other carbon based substances onto metal or nonmetal surfaces without loss of biological activity and/or structure is described. The method is based on generating a charged corona plasma which is then introduced into a vacuum chamber to deposit the biomaterial onto a biased substrate. The deposited biomaterials can be selected for a variety of medical uses, including coated implants for in situ release of pharmaceuticals.

A novel chemistry, system and application technique reduces contamination of semiconductor wafers and similar substrates and enhances and expedites processing. A stream of liquid chemical is applied to the workpiece surface. Ozone is delivered either into the liquid process stream or into the process environment. The ozone is preferably generated by a high capacity ozone generator. The chemical stream is provided in the form of a liquid or vapor. A boundary layer of liquid or vapor forms on the workpiece surface. The thickness of the boundary layer is controlled. The chemical stream may include ammonium hydroxide for simultaneous particle and organic removal, another chemical to raise the pH of the solution, or other chemical additives designed to accomplish one or more specific cleaning steps.

The present invention relates to functional fluid compositions containing friction modifiers, and specifically stable compositions containing friction modifiers with limited solubility in and/or limited compatibility with the functional fluids with which they are used. In particular the present invention deals with functional fluids used in internal combustion engines, such as engine oils, and phosphorus-containing friction modifiers, where the friction modifier is present in the functional fluid composition at levels that would otherwise cause the composition to be unstable and/or hazy.

The invention relates to a method for preparing an organic fertilizer through processing agriculture and forestry wastes by using an organic solvent. The method comprises the following steps: processing the agriculture and forestry wastes in high-temperature and high-pressure organic solvent environment to completely or partially depolymerize cellulose, hemicellulose, lignin and other chemical components in plant raw materials in order to dissolve above chemical components in a waste liquid, and distilling and drying the waste liquid to obtain the solid organic fertilizer and recover the organic solvent. The plant raw materials are depolymerized and degraded by the organic solvent to form the organic fertilizer which can be easily degraded by microorganisms and absorbed by plants, so the plant raw materials can improve soil and increase the fertility. The organic fertilizer obtained after processing with the polar organic solvent has limited solubility in water, contains abundant phenolic hydroxyl groups, carboxylic groups and other ionizable groups, can be combined with Ca, Mg, B, Zn, Se, Fe, Mn, Cu, Mo and other trace elements, and can be used as a sustained and controlled release fertilizer. The method converts the agriculture and forestry wastes into the organic fertilizer only through using the organic solvent without any acid or alkali, so the method has the advantages of low cost and good economic benefit.

A system for printing a liquid toner is provided comprising a liquid electrographic toner composition comprising a liquid carrier having a Kauri-Butanol number less than about 30 mL and a plurality of charged toner particles dispersed in the liquid carrier, wherein the toner particles comprise a polymeric binder. The system also comprises a charge control adjuvant having limited solubility in the liquid carrier. The charge control adjuvant preferably is present in the liquid carrier in an amount in excess of the solubility of the adjuvant in the liquid carrier. Alternatively, the charge control adjuvant may be dispersed in a matrix having limited solubility in the liquid carrier or encapsulated within a matrix to form microcapsules having limited solubility in the liquid carrier. The charge control adjuvant in any of the above forms may be provided in a number of formats for release into the toner composition as needed. The charge control adjuvant is released into the toner composition as needed to provide charge control relative to the bulk conductivity of the toner composition and/or the charge per unit mass of the toner particles.

This invention relates to a new process to directly produce transportation gasoline from synthesis gas containing principally carbon monoxide, carbon dioxide, and hydrogen. The process entails three sequential catalytic stages with intermediate heat exchange to provide the requisite temperature in each stage, but with no interstage separation. The recycle loop enhances the conversion of the synthesis gas to the desired products and also serves as heat sink for the highly exothermic reactions involved in each stage.

Cross-linked zein articles are prepared by a melt process where zein is mixed with polyethylene maleic anhdyride. The melt processing can be conducted as a batch process (e.g., as in a torque rheometer) or as a continuous process (e.g., as in reactive extrusion using a screw extruder). This process provides a zein article that has reduced solubility in acetic acid (a solvent that normally dissolves unaltered zein) and/or increased tensile strength.

The invention relates to a copolymer for a charge transport layer in an optoelectronic device and in particular in a light-emitting diode (LED), having a charge mobility of at least 1.0×10¹⁰ m²/V.s, and comprising at least a first and a second monomer, characterized in that the ratio of the solubilities of homopolymers made from the first and the second monomer in a first solvent is more than 10. This copolymer allows a (semi) conductive polymer to be cast to form a first layer and prevents it from being dissolved in the solvent of a subsequently deposited second, e.g. light-emitting layer. The invention further relates to a LED comprising a copolymer according to the invention.
