Abstract: A system for notifying environmental pollution status includes wireless environment sensing devices and a portable wireless environmental pollution status notification device. The wireless environment sensing devices, respectively arranged in the different sensing locations of a physical environment, respectively store the sensing locations and respectively sense pollution related information corresponding to the different sensing locations to output the pollution related information and the sensing locations corresponding thereto. The portable wireless environmental pollution status notification device, wirelessly connected to the plurality of wireless environment sensing devices and located in the physical environment, receives the pollution related information and the sensing locations corresponding thereto and generates notification signals based on the pollution related information and the sensing locations corresponding thereto.

Abstract: A positioning pollutant-measuring system includes a cloud server, a wireless base station, an automatic moving vehicle, and a positioning pollutant-measuring device. The automatic moving vehicle carries the positioning pollutant-measuring device and passes through different locations. The positioning pollutant-measuring device receives location related parameters from the wireless base station and measures the air flow rates or the air humidity of the different locations to adjust a resolution for measuring pollutants corresponding to the different locations.

Abstract: This invention relates to waterborne coating compositions having improved compatability with metal pigments, i.e., improved shelf life and reduced gassing and gellation. The compositions comprise at least one aqueous dispersion of (1) at least one emulsion copolymer polymerized from (a) at least one ethylenically unsaturated anionic monomer and (b) at least one other olefinically unsaturated monomer, said copolymer being made using at least one phosphate surfactant having at least one phosphorus acid group or salt thereof, said copolymer being crosslinked, and (2) at least one non-water soluble metal pigment. The compositions are useful in paints and other coatings.

Abstract: Thiocarbonate compounds which, in one embodiment, are utilized as a rheology modifier or associative thickener. The thiocarbonate compounds thicken or increase the viscosity of a composition, preferably an aqueous composition when used in an effective amount. In one preferred embodiment, the thiocarbonate compounds include at least one hydrophilic group containing repeat unit such as derived from acrylic acid, and at least one hydrophobic group to enhance association with other compounds and thus increase viscosity of a composition. Aqueous composition comprising a latex and thiocarbonate associative thickeners are described.
