Abstract: The present invention deals with the serious pollution problems from electric power plants that burn coal which may be forced to shut down by virtue of their being uneconomical to be retrofitted with expensive pollution controls. The pollutants from coal-burning power stations comprise SO2, NOx, Hg, Particulate Matter, Ash, and CO2. This invention offers a unique and comprehensive solution that makes possible the prevention of the ill-effects currently caused to health and environment while at the same time would also prevent the closure of these badly needed power generation facilities that provide some 50% of the electricity generated in this country. The herein comprehensive solution converts the six mentioned pollutants into valuable products and thus avoids the discharge of such pollutants into the atmosphere.

Abstract: A glass substrate having an oleophobic surface. The surface is substantially free of features that form a reentrant geometry and includes a plurality of gas-trapping features extending from the surface to a depth below the surface and a coating comprising at least one of a fluoropolymer and a fluorosilane. The gas-trapping features are substantially isolated from each other, and trap gas below droplets to prevent wetting of the surface.
Abstract: A glass and an enclosure, including windows, cover plates, and substrates for mobile electronic devices comprising the glass. The glass has a crack initiation threshold that is sufficient to withstand direct impact, has a retained strength following abrasion that is greater than soda lime and alkali aluminosilicate glasses, and is resistant to damage when scratched. The enclosure includes cover plates, windows, screens, and casings for mobile electronic devices and information terminal devices.

Abstract: A clean dry white glass powder useful as a substitute for Portland cement in concrete, in paints, and for other known uses for glass powder produced conventionally can be produced from unsorted post-consumer waste glass, including a substantial fraction of non-glass items, by employing glass pulverizing equipment to reduce waste glass to small fragments, allowing removal of trash, employing a multistep washing process to clean the glass fragments, in the preferred embodiment using aggregate cleaning equipment, drying the fragments, preferably using fluidized bed techniques, and grinding the glass to a desired particle size, preferably using a ball mill, in combination with an air classification step to produce a bright white glass powder of uniform particle size.

Abstract: A glass for use in chemical reinforcement for use in a substrate of an information recording medium, having a composition comprising, denoted as mol %: SiO2 47 to 70%? Al2O3 1 to 10% (where the total of SiO2 and Al2O3 is 57 to 80%) CaO 2 to 25% BaO 1 to 15% Na2O 1 to 10% K2O 0 to 15% (where the total of Na2O and K2O is 3 to 16%) ZrO2 1 to 12% MgO 0 to 10% SrO 0 to 15% (where the ratio of the content of CaO to the total of MgO, CaO, SrO, and BaO is greater than or equal to 0.5) ZnO 0 to 10% (where the total of MgO, CaO, SrO, BaO, and ZnO is 3 to 30%) TiO2 0 to 10% and the total content of the above-stated components is greater than or equal to 95%. A glass for use in chemical reinforcement for use in the substrate of an information recording medium employed in a perpendicular magnetic recording system, in which the glass exhibits the glass transition temperature is greater than or equal to 600° C.
Abstract: The invention relates to a method for treating an ammonium halogenide and/or residue containing organic aminhydrohalogenides, produced during the production of an amino-functional organosilane of general formula (I) R2N[(CH2)2NH]z(Z)Si(R?)n(OR?)3-n (Ia), wherein the production of the amino-functional organosilane according to formula (Ia) is based on the conversion of a halogen-functional organosilane of general formula (II) X—Z—Si(R?)n(OR?)3-n (II), with excess ammonia or an organic amine of general formula (III) RNH[(CH2)2NH]zR (III) and subsequently separating and treating the raw product and the resulting residue containing salt. The treatment consists of adding an essentially non-polar organic solvent and an aqueous lye to the residue. The mixture is reacted, subsequently the aqueous phase is separated from the organic phase, the organic solvent contained in the organic phase is removed from said phase and the residual organic phase is recovered.
Abstract: The invention relates to a process for producing a porous glass construct with interconnected porosity, the resulting porous construct and its use as a macroporous scaffold in bone repair and regeneration.
