Abstract: Described are aqueous rechargeable hydrogen batteries operating in the full pH range (e.g., pH: ?1 to 15) with potential for electrical grid storage. The pH-universal hydrogen batteries operate with different redox chemistry on the cathodes and reversible hydrogen evolution/oxidation reactions (HER/HOR) on the anode. The reactions can be catalyzed by a highly active ruthenium-based electrocatalyst. The ruthenium-based catalysts exhibit comparable specific activity and superior long-term stability of HER/HOR to that of state-of-the-art Pt/C electrocatalyst in the full pH range. New chemistries for aqueous rechargeable hydrogen batteries are also provided.

Abstract: A wallpaper includes a support portion having a flat surface, and a functional layer disposed on the flat surface of the support portion. The functional layer includes a metallic film and has an emissivity of greater than zero and equal to or less than 0.6. The wallpaper further includes a particulate layer disposed on the functional layer and including a polymer body and inorganic particles dispersed in the polymer body.

Abstract: A metallized breathable composite textile includes a lining layer and a metallized non-woven sheet disposed on the lining layer. The metallized non-woven sheet includes a base layer containing a polymer and a metal layer deposited on a first surface of the base layer. The lining layer is connected to the metallized non-woven sheet via point contacts.

Abstract: A thermoregulation article includes a metal film, a polymer film disposed on the metal film, and a colorant film disposed on the metal film. The thermoregulation article has at least one side having an average reflectivity greater than 0.5 at a wavelength of 0.3-4 ?m and an average emissivity less than 0.4 at a wavelength of 4-20 ?m.

Abstract: The method for forming a water sterilization electrode includes heating a conductive medium to an elevated temperature in a heating apparatus. The method further includes growing oxide nanostructures on the conductive medium at the elevated temperature by supplying one or more oxidizing gases to the heating apparatus. The method further includes ramping down from the elevated temperature at 2-30° C./min to a room temperature to form the water sterilization electrode having the oxide nanostructures on the conductive medium.
