The present invention provides a surface treatment method that improves antimicrobial activity of copper or a copper alloy and enhances immediate effects of antimicrobial actions on the surface of the copper or the copper alloy. A surface treatment method for copper or a copper alloy according to the present invention comprises preparing a reducing agent solution containing a biological reducing substance, and treating the surface of the copper or the copper alloy with the reducing agent solution. The present invention also provides a surface treatment liquid for sterilizing copper or a copper alloy, in which the surface treatment liquid contains a biological reducing substance. The present invention also provides a sterilization method that comprises bringing copper or a copper alloy treated by the surface treatment method into contact with a surface of an object to sterilize the surface of the object.

Athletic footwear often emits unpleasant odors after being used. As a result, athletic footwear is sometimes placed in a separate shoe bag with the purpose of carrying the footwear in isolation. However, current bags for athletic footwear have little to no effect on absorbing or neutralizing unpleasant odors, they merely contain the odor. The presently disclosed technology provides a space effective, odor-combatting athletic shoe bag.

The antibacterial deodorant composition according to the present invention includes an aqueous colloidal solution containing 1,500-2,500 ppm of nonionic copper nanoparticles having an average diameter (D50) of 2-10 nm.

Disclosed herein are multi-layer structures comprising a first composite layer disposed over a second composite layer, wherein the first composite layer contains a first active material dispersed in a first polymer containing an elastomeric polymer and the second composite layer contains a second polymer which may have a second active material dispersed therein, wherein the first active material chemically or physically interacts with at least one toxic chemical and is selected from the group consisting of metal-organic frameworks (MOFs), metal oxides, metal hydroxides, zeolites, and combinations thereof, and wherein the active material and the second active material (if present) are the same as or different from each other, and the first polymer and second polymer are the same as or different from each other, subject to the proviso that the first composite layer and the second composite layer compositionally differ from each other in at least one respect.

A straw structure is provided. The straw structure includes a straw body, and the straw body has a first beveled edge at an opening of a bottom end of the straw body and a second beveled edge connected to a rear side of the first beveled edge. A puncturing end opening is formed at the first beveled edge and a side edge of the straw body, and the bottom end of the straw body has a beveled opening formed at the second beveled edge. The puncturing end opening is an acute angle that is less than 90 degrees, and a slope of the second beveled edge is greater than a slope of the first beveled edge.

A process is described utilizing a composition of nano particles to form a foam and applying the foam to a surface to be disinfected.

Described herein is a cover for mounting to a door handle (30) comprises two parts (10, 12) configured for mutual locking engagement such that when the parts are brought into mutual locking engagement around a door handle (30) at least a portion of the door handle is substantially enclosed within a cavity (16) formed between the two parts (10, 12). At least a portion of at least one of the parts (10, 12) is coated, impregnated, or otherwise provided with a self-cleaning material. Also described is a push plate device comprising a first plate (72) for fixing to a door; and a second plate (71) configured to releasably attach to said first plate in order to form a composite plate structure (70). The second plate (71) is at least partly coated, impregnated, or otherwise provided with a self-cleaning material so that the composite plate structure (70) presents a self-cleaning external surface.
