||14895170||SUMITOMO METAL MINING CO., LTD.||Hideki OHARA|
A wastewater treatment process capable of selectively and efficiently separating and removing a manganese precipitate with high purity from sulfuric acid-acidic wastewater containing aluminum, magnesium, and manganese. In the wastewater treatment for a sulfuric acid-acidic wastewater containing aluminum, magnesium, and manganese, a magnesium oxide is used for part or all of the neutralizing agent to be added, the magnesium oxide is produced through the following steps (1) to (4): (1) effluent wastewater obtained by separating aluminum and manganese from sulfuric acid-acidic wastewater is concentrated, and calcium contained in the effluent wastewater is precipitated as a calcium sulfate; (2) the solution obtained in (1) is further concentrated, and magnesium is precipitated and separated as a magnesium sulfate; (3) the magnesium sulfate separated in (2) is roasted together with a reducing agent to obtain a magnesium oxide and sulfurous acid gas; and (4) the magnesium oxide obtained in (3) is washed.

20160115081 LOW TEMPERATURE, NANOSTRUCTURED CERAMIC COATINGS||US||28.04.2016|
||14734520||The Research Foundation for the State University of New York||Junghyun Cho|
A substrate subject to degradation at temperatures above 100° C. is coated with a nanostructured ceramic coating having a thickness in excess of 100 nm, formed on a surface of the substrate, wherein a process temperature for deposition of the nanostructured coating does not exceed 90° C. The coating may be photocatalytic, photovoltaic, or piezoelectric. The coating, when moistened and exposed to ultraviolet light or sunlight, advantageously generates free radicals, which may be biocidal, deodorizing, or assist in degradation of surface deposits on the substrate after use. The substrate may be biological or organic, and may have a metallic or conductive intermediate layer.
