CARRIER-FREE OXYGEN REDUCTION CATALYST FOR USE IN LOW-TEMPERATURE FUEL CELLS AND METHOD FOR PRODUCING SAME
An oxygen reduction catalyst for use in low-temperature fuel cells and a method for the production thereof. This is in particular carrier-free and free from precious metals. It is based on a conductive polymer produced from a nitrogenous aromatic monomer, which leads to conductive polymers, and an aromatic sulfonic acid, which polymer is pyrolyzed together with one or more transition metal salts and is subsequently acid etched. In one particularly advantageous configuration variant, this involves a polypyrrole produced with sulfanilic acid as a doping agent.

METHOD FOR MONITORING FLUORESCENT POLYMER ANTISCALANTS IN INDUSTRIAL WATER SYSTEMS
The present invention relates to a fluorescently-tagged (co)polymer and use thereof useful as a scale inhibitor in industrial water systems. Said (co)polymer comprises a (i) reactive fluorescent compound selected from a benzodiazole compound (ii) at least one monoethylenically unsaturated acid monomer, and (iii) optionally, at least one monoethylenically unsaturated acid-free monomer.
Ultra-thin, pinhole-free, flexible metal-organic films
Described herein are facile, one-step initiated plasma enhanced chemical vapor deposition (iPECVD) methods of synthesizing hyper-thin (e.g., sub-100 nm) and flexible metal organic covalent network (MOCN) layers. As an example, the MOCN may be made from zinc tetraphenylporphyrin (ZnTPP) building units. When deposited on a membrane support, the MOCN layers demonstrate gas separation exceeding the upper bounds for multiple gas pairs while reducing the flux as compared to the support alone.
