Abstract: The ionic liquid-based coating is a coating for both porous and nonporous materials. As non-limiting examples, a porous substrate coated with the ionic liquid-based coating may be used to disinfect and remove microorganisms from air and water, to provide an antimicrobial surface for preventing microbial contamination, or to enhance filtration efficiency of the porous material for airborne and waterborne particulate matter without increasing flow resistance. As a further non-limiting example, a nonporous substrate coated with the ionic liquid-based coating may be used to form a surface capable of self-disinfection from microorganisms contacting surface. The ionic liquid-based coating includes at least one ionic liquid, an adhesive, and at least one additive, which may be a disinfectant, a viscosity modifier, a pH buffer, a fragrance, or combinations thereof.

Abstract: A multi-walled titanium-based nanotube array containing metal or non-metal dopants is formed, in which the dopants are in the form of ions, compounds, clusters and particles located on at least one of a surface, inter-wall space and core of the nanotube. The structure can include multiple dopants, in the form of metal or non-metal ions, compounds, clusters or particles. The dopants can be located on one or more of on the surface of the nanotube, the inter-wall space (interlayer) of the nanotube and the core of the nanotube. The nanotubes may be formed by providing a titanium precursor, converting the titanium precursor into titanium-based layered materials to form titanium-based nanosheets, and transforming the titanium-based nanosheets to multi-walled titanium-based nanotubes.

Abstract: Microbial disinfection is performed using continuous or intermittent lighting using one or more narrow wavelength light sources. The light sources illuminate with narrow wavelength characteristics. The lighting provides a sufficiently high intensity for rapid microbial disinfection process, while reducing the average energy consumption for microbial disinfection during the microbial disinfection process by targeting multiple cellular sites along different inactivation pathways.

Abstract: A gel composition for air freshening or disinfecting, comprising a silicon alkoxide or colloidal silica, a volatile or gaseous fragrance and/or disinfectant, water, an acid or base catalyst, a water-soluble solvent, and optionally other volatile components and additives, and a method for preparing the same. The gel can be transparent or colored, has a homogeneous texture and a soft to rigid structure, and contains volatile or gaseous components from 0 vol % to 85 vol % for scented materials (fragrance and oils) and/or 0-8000 ppm of disinfectant, which are released at a steady rate under ambient conditions, controlled by the shape and opening of the gel container. Botanicals or plastic decorations may be added into the gel to improve its aesthetic appeal. The preparation method is easier and requires less energy consumption and the gel is used as an air freshener or disinfectant.

Abstract: The moisture-resistant catalyst for air pollution remediation is a catalyst with moisture-resistant properties, and which is used for removing nitrogen compound pollutants, such as ammonia (NH3), from air. The moisture-resistant catalyst for air pollution remediation includes at least one metal oxide catalyst, at least one inorganic oxide support for supporting the at least one metal oxide catalyst, and a porous framework for immobilizing the at least one metal oxide catalyst and the at least one inorganic oxide support, where the porous framework is moisture-resistant. As non-limiting examples, the at least one metal oxide catalyst may be supported on the at least one inorganic oxide support by precipitation, impregnation, dry milling, ion-exchange or combinations thereof. The at least one metal oxide catalyst supported on the at least one inorganic oxide support may be physically embedded in the porous framework.

Abstract: A self-humidifying fuel cell is made by preparing a porous substrate, coating the substrate with a zeolitic material (or a graphene derivative) and filling the pores with a mixture of graphene derivative and proton-conducting material (or a proton-conducting material). The coating of the substrate includes selecting a zeolitic material, and applying coating on the pore walls and surface of the porous substrate, to form zeolitic material-coated pores. The resulting composite material is used as a self-humidifying proton-conducting membrane in a fuel cell.
