Abstract: An apparatus used with supplied power for treating air in an environment and method of use. A housing is mobile in the environment and has an intake and an exhaust. At least one prime mover is disposed in the housing and is operable to move the air in the environment through the housing from the intake to the exhaust. At least one ultraviolet light source is disposed in the housing, is in electrical communication with the supplied power, and is configured to generate ultraviolet radiation in at least one a portion of the housing through which the moved air passes from the intake to the exhaust. At least one permeable barrier is disposed in the housing and is configured to impede the moved air flow therethrough up to an impedance threshold. The permeable barrier is in electrical communication to the supplied power and is heated to a surface temperature.

Abstract: An aspect of the present disclosure provides time and energy-efficient synthesis of catalysts for water electrolysis. An exemplary synthesis method includes dissolving amounts of Fe(NO3)3.9H2O and Na2S2O3.5H2O in deionized water at ambient temperature to form a solution, placing Ni foam into the solution where the Ni foam serves as a substrate and a Ni source for growth of sulfur-doped (Ni,Fe)OOH (S—(Ni,Fe)OOH) catalysts, leaving the Ni foam in the solution at ambient temperature for a duration between one minute and five minutes to provide a treated foam where the S—(Ni,Fe)OOH catalysts grow on the substrate during the duration, and removing the treated foam from the solution after the duration.

Abstract: A detoxification device for removing pathogens from air within an environment. The detoxification device may include a filtration media for catching and retaining particles larger than about 0.3 micrometers (?m) with an efficiency of at least 99%. The detoxification device may also include a heating element having a metallic foam. The heating element may be heated upon application of an electrical current to the heating element. The heating element may, upon being heated, heat the filtration media to a target temperature that is effective to kill a pathogen.

Abstract: A method for ambient-temperature synthesis of a catalyst for water electrolysis by dissolving an amount of an Fe2+ source and optionally an amount of a salt of another divalent cation in deionized water at ambient temperature to form a solution, placing nickel (Ni) foam into the solution, whereby the Ni foam serves as a substrate and/or a Ni source for growth of the catalyst, leaving the Ni foam in the solution at ambient temperature for a time duration in a range of from about 0.5 hour to about 4 hours to provide a treated foam, during which time duration, the catalyst is grown on the substrate, and removing the treated foam from the solution after the time duration, wherein the treated foam comprises the catalyst grown thereon.

Abstract: A stable three-dimensional core-shell metal-nitride catalyst consisting of NiFeN nanoparticles decorated on NiMoN nanorods supported on porous Ni foam (NiMoN@NiFeN), which functions as an oxygen evolution reaction catalyst for alkaline seawater electrolysis. It yields large current densities of 500 and 1000 mA cm?2 at overpotentials of 369 and 398 mV, respectively, in alkaline natural seawater at 25° C. Combined with an efficient hydrogen evolution reaction catalyst of NiMoN nanorods, current densities of 500 and 1000 mA cm?2 at low voltages of 1.608 and 1.709 V, respectively are achieved for overall alkaline seawater splitting at 60° C.

Abstract: An apparatus is used with supplied power for treating air flow of an air handing system of a facility. A frame has a plenum with an inlet and an outlet. The frame is configured to position in the air flow of the air handing system for passage of the air flow therethrough. A filter is disposed in the plenum and is configured to filter the air flow therethrough up to a filtration threshold. An ultraviolet light source disposed in the plenum is connected in electrical communication with the supplied power and is configured to generate ultraviolet radiation in the plenum. A permeable metal barrier disposed in the plenum is configured to impede the air flow therethrough up to an impedance threshold. The barrier is connected in electrical communication to the supplied power and is heated to a surface temperature.
