The present invention generally relates to a process for fabricating a reduced graphene oxide (rGO)-based antifouling marine coating is disclosed. The process begins with preparing a dispersed graphene oxide solution, followed by chemical reduction using hydrazine hydrate at 90-95 C. for 3 hours to form a dispersed rGO solution. This solution is then washed, filtered, and sonicated for 6 hours to ensure stability. A polymer solution is prepared by dissolving 40-50 wt % epoxy resin in acetone at 50 C. The antifouling composite is then formed by combining the rGO solution, 10-15 wt % zinc oxide nanoparticles, and 1-5 wt % carbon nanotubes with the polymer solution, followed by 6 hours of sonication at room temperature. Finally, the resulting composite material is applied to a substrate as a coating using spraying, brushing, dipping, or spin coating. This coating offers a promising solution for preventing biofouling on marine structures.

Disclosed herein is an anti-pathogenic aerosol composition comprising an alcohol selected from ethanol and isopropanol; an alkyldimethylbenzylammonium compound; polyhexanide; and water.

A method of preparing a product for the release of volatile hydrophobic material includes (i) providing a solid article comprising a polymer gel matrix formed from a chemically cross-linked material; and (ii) absorbing the volatile hydrophobic material into the solid article by contacting the solid article with liquid phase volatile hydrophobic material until the solid article comprises at least 5 wt % of the volatile hydrophobic material, based on a final weight of the solid article. The solid article is non-porous. The product is able to provide release of the volatile hydrophobic material by volatilization of the volatile hydrophobic material from the solid article at a temperature of 25 C., a relative humidity of 60%, and atmospheric pressure.

Disclosed are compositions developed for the denaturation of respiratory allergens, such as mite, pollen, feline, canine, mold and fungal allergens. In particular, disclosed are water based compositions of vegetable origin, which prevent allergic reactions in the body by denaturing respiratory allergens before they enter the body through the respiratory tract, while they are still in the environment. Different versions of compositions are disclosed containing at least one acid, at least one herbal essential oil, an anionic surfactant or cyclodextrin, as well as water.

Methoxy polyethylene glycol for use as a medicament, in particular in skin healing, wound healing and treatment of a microbial infection. A method for treating a medical device and/or implant to reduce or eliminate microbial contamination comprises applying a liquid formulation comprising methoxy polyethylene glycol. This invention relates to the novel discovery that methoxy polyethylene glycol, an inactive polymer with no known pharmacological effect, was able to come between microbes and a surface, removing the microbes or releasing the attachment or adherence of the microbes to the surface and thereby improving wound healing significantly, eliminating infections and colonies of microbes.

A method for treating a pathogen, comprising the steps of: forming a polyethylenimine with hydrochloric acid in a solution, the polyethylenimine comprising secondary amines, the secondary amines being at least partially protonated; adding sodium hydroxide to the solution of the polyethylenimine to increase a pH of the solution by at least one pH unit, such as to above 9; removing at least five percent of non-amine cations, such as sodium ions, in the solution from the solution; lowering the pH, subsequent to the step of removing, of the solution, such as to below 6, to yield a protonation level of the secondary amines in excess of fifty percent; and inactivating at least 50% of a bacteria within 10 minutes of contact of the bacteria with the solution.

Provided herein are embodiments of molecular iodine-infused polymers, articles, and products, preparation of same, and uses of same.
