    Abstract: The invention discloses a self-derivative iron-containing nickel anode for alkaline water electrolysis and its preparation method. The anode comprises a nickel substrate and catalytic material layer. The catalytic layer is disposed on and integrated with the surface of the nickel substrate. The catalytic layer contains nickel oxide with iron components. The nickel oxide results from the reaction of the surface layer of the nickel substrate with an oxidant-rich alkaline solution and forms a nanosheet array layer. A nickel-oxidation state containing the iron component is formed by electrochemically induced iron-ion corrosion of the nickel-oxidation state. The invention can effectively reduce the potential difference between the anode and cathode of an electrolysis cell, thereby significantly reduces energy consumption and improves the efficiency of water electrolysis.

    Abstract: Processes for cleaning anodic film pore structures are described. The processes employ methods for gas generation within the pores to flush out contamination within the anodic film. The pore cleaning processes can eliminate cosmetic defects related to anodic pore contamination during the manufacturing process. For example, an anodic film that is adjacent to a polymer piece can experience contamination originating from a gap between the anodic film and polymer piece, which can inhibit colorant uptake of the anodic film in areas proximate the polymer piece. In some cases, an alternating current anodizing process or a separate operation of cathodic polarization is implemented to generate hydrogen gas that bubbles out of the pores, forcing the contaminates out of the anodic film.

    Abstract: Passive radiative cooling panels are produced by anodizing an aluminum foil sheet to form metamaterial nanostructures and then forming a plated metal over the metamaterial nanostructures to produce an ultra-black emitter, and then securing a reflective layer (e.g., a solar mirror film) onto the ultra-black emitter. The process is implementable in a roll-to-roll-type fabricating system in which a continuous aluminum foil ribbon extends from a feed roll through an anodization station to a reflector mounting station such that a first ribbon section undergoes anodization while a second ribbon section undergoes plating and a reflective layer is mounted onto a third ribbon section. A modified Anodic Aluminum Oxide (AAO) self-assembly technique is utilized to generate tapered nanopores that are then plated to generate an ultra-black emitter capable of generating broadband radiant energy with an emissivity close to unity. Modules are produced by mounting the panels onto conduit structures.

    Abstract: An alumina nanohole array and a method of fabricating the same includes the steps of forming an aluminum thin-film on a substrate at a substrate temperature of −80° C. or below so that crystal grain growth is suppressed, even when a high-purity aluminum material is used, thus providing improved surface smoothness; and anodizing the aluminum thin-film. Preferably, the method additionally includes texturing by pressing a mold having an orderly array of projections against the aluminum thin-film to form pits on the aluminum thin-film which enables a larger array area to be formed. When the mold and the aluminum thin-film are held at a temperature of 150 to 200° C., the pressure used for pit formation is reduced. A magnetic recording medium manufactured by a method therefore includes forming a magnetic layer within the nanoholes so that the medium is suitable as a bit patterned media for a perpendicular recording system.
