Abstract: Methods of enhancing the anti-virus capabilities of surfaces directly contacted by humans. The methods include applying a hydrophobic coating material to a surface of an article to form a hydrophobic surface coating overlying the surface such that the hydrophobic surface coating defines a hydrophobic outer surface of the article. The hydrophobic outer surface is more hydrophobic than the surface of the article, and a liquid that contains suspended viruses and is deposited on the hydrophobic outer surface exhibits a contact angle relative to the hydrophobic outer surface that is greater than a contact angle of the liquid if directly deposited on the surface of the article, and the hydrophobic outer surface thereby increases inactivation of the viruses suspended in the liquid as compared to the surface of the article to which the hydrophobic coating material was applied.

Abstract: A disinfectant sprayer assembly, including a tank defining a volume, a disinfectant suspension contained within the volume, a nozzle having a size variable spray opening, a pump operationally connected to the volume and to the nozzle for pumping disinfectant from the volume through the spray opening to apply disinfecting to a predetermine surface having a predetermined set of physical characteristics for a period of time, an ion generator operationally connected to the volume for ionizing the disinfectant suspension, and a microprocessor operationally connected to the size variable spray opening. The ion generator voltage, spray opening size, and distance between the predetermined surface and the spray opening are predetermined based on the predetermined set of physical characteristics of the surface.

Abstract: A reduced noise curved surface, including the elements of a curved substrate and a plurality of micropillars operationally connected to the curved substrate and defining a coating, wherein the respective micropillars are positioned to define an aperiodic sequence based on the golden ratio, and wherein the plurality of aperiodically sequenced micropillars increase sound absorption and drag reduction of the curved surface.

Abstract: A mask assembly comprising a face covering portion, a pocket connected to the face portion and positioned to cover a wearer’s nose and mouth, where in a filter is removably inserted into the pocket, the filter comprising a porous hydrophobic and lipophobic layer, a diamond - like carbon coated copper layer, and a non- woven fabric layer. A filter containing at least one porous hydrophobic and lipophobic layer, at least one diamond like carbon coated copper layer interposed between two non-woven fabric layers, and at least one additional non- woven fabric layer. A filter comprising at least one porous hydrophobic and lipophobic layer, at least one diamond - like carbon coated copper layer, and at least one non - woven fabric layer, the at least diamond-like carbon coated layer is between the at least one porous hydrophobic and lipophobic layer and at least one non - woven fabric layer.
