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: 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: Provided herein are wide spectrum microbicidal and microbiostatic nanoproducts, and formulations and preparations of wide spectrum microbicidal and microbiostatic nanoproducts, that comprise a mono or multicomponent nanostructure having microbicidal and microbiostatic properties. Also provided are methods for the use of wide spectrum microbicidal and microbiostatic nanoproducts, as well as formulations and preparations thereof, in a variety of applications such as, for example, disinfection processes.

Abstract: Provided are halogen-free coatings, and methods for making and using such halogen-free coatings, for water and oil protection or repellants, which coatings control and/or eliminate the effect of humidity and oily substances on one or more of a variety of surfaces. These coatings and methods exhibit minimal toxicity to humans, non-human animals, including pets, and the environment more generally. The presently-disclosed coatings, which do not contain a halogen component, may be suitably employed, for example, on monuments, textiles, metals, stone, ceramic, wood, or other surface.
