The present disclosure is directed to alcohol-based anti-adherent compositions that do not adhere to or attract Gram-negative and Gram-positive bacteria once it is applied to a surface and dried. The composition may include as anti-adherent agents, hydrophilic film-formers such as cellulosics, gums, acrylates, nonionic polymers, and anionic polymers. Examples of anti-adherent agents include Hydroxypropyl methylcellulose, Cellulose gum, Acacia Senegal Gum; Polyacrylate Crosspolymer-11, VP/Dimethylaminoethylmethacrylate/Polycarbamyl Polyglycol Ester; Acrylates/Vinyl Neodecanoate Crosspolymer, hydroxypropyl methylcellulose, Hydroxypropylcellulose, Methylcellulose, Propylene Glycol Alginate, Polyacrylate Crosspolymer-6, VP/Polycarbamyl Polyglycol Ester, Acrylates/Steareth-20 Methacrylate Copolymer; Acrylates Copolymer, and any combination thereof. The anti-adherent may be applied to surfaces using a vehicle such as a wipe.

There are provided a method for producing particles by suspension polymerization which ensures an excellent dispersion stability of the monomer and a simpler washing step, composite particles obtainable by this production method, and use of the composite particles. The method for producing composite particles includes a polymerization step of subjecting a monomer mixture which contains a polymerizable vinyl monomer to aqueous suspension polymerization in a presence of small polymer particles having a volume-average particle size of 20 to 500 nm, with a water-soluble cellulose compound adsorbing on surfaces of the small polymer particles, and thereby obtaining composite particles which contain the small polymer particles and large polymer particles greater than the small polymer particles.

There is provided a silver powder, which is able to obtain a conductive paste having a high thixotropic ratio and a high Casson yield value and which is able to form a conductive pattern having a low resistance, and a method for producing the same. An aliphatic amine such as hexadecylamine is added to a silver powder, the surface of which is coated with a fatty acid such as stearic acid, to be stirred and mixed to form the aliphatic amine on the outermost surface of the silver powder while allowing the fatty acid to react with the aliphatic amine to form an aliphatic amide such as hexadecanamide between the fatty acid and the aliphatic amine.

A filtration membrane coating comprising a hydrophilic polymer, a surfactant, and one or more charged compounds, each containing one or more sulfonate functionalities and one or more linkable functionalities selected from the group consisting of amine, monochlorotriazine, and dichlorotriazine. The hydrophilic polymer and surfactant form a thin primer layer which is also superhydrophilic. The primer layer improves flux, and enables improved adhesion of the one or more charged compounds, which form a charged dye layer on top of the primer layer when enhances rejection of charged divalent ions. The coating can be applied while the membrane is packaged in its final form, such as in a spiral wound or other configuration.
