The present disclosure relates to methods and system for disinfecting surfaces within an area by forming peracids in a reaction layer in situ on the surfaces to be disinfected. Aqueous compositions comprising peracid reactant compounds, particularly hydrogen peroxide and acetic acid, are sequentially dispersed into the area, preventing peracids from being formed until the two peracid reactant compounds contact each other on the surface to be disinfected. Additionally, aqueous compositions containing peracid reactant compounds can further comprise ethanol to both decrease the surface tension of the droplets and enhance the reactants' biocidal activity. Peracid reactant compounds can be sequentially dispersed as electrostatically-charged droplets, so that droplets of a first aqueous composition containing at least one peracid reactant compound are dispersed with a polarity opposite that of a subsequently-applied second aqueous composition containing at least one peracid reactant compound, driving formation of a peracid on the surface in situ.

The present disclosure relates to methods and system for disinfecting surfaces within a volumetric space by forming peracids in a reaction layer in situ directly on the surfaces to be disinfected. Particularly, a peroxide compound and an organic acid are sequentially dispersed into the volumetric space, preventing peracids from being formed until the two reactants contact each other on the surface to be disinfected. In some embodiments, any of the dispersed aqueous compositions can optionally be electrostatically charged. Additionally, a system for sequentially dispersing the peracid reactant compounds by electrostatic spraying is provided.

An ionising device is described comprising a tubular bulb of electrically insulating or dielectric material extending along a longitudinal reference axis and having the two opposite longitudinal terminal ends and open, a tubular cathode engaged in the bulb, a tubular anode fitted onto the bulb, a pair of covers coupled to a relative end of said bulb so as to hermetically close it, and a conductive electrode comprising a stem extending into said bulb, and a plurality of conductive crowns which are fitted onto the stem at predetermined distances from each other and are suitable to exert an elastic compression on the tubular cathode against the inner surface of the bulb.

A method of forming a material structure from structural units contained within a liquid solution in a spray head is described. The liquid solution includes a solvent and a solute, the solute comprising a plurality of the structural units, the structural units including monomer units, oligomer units, or combinations thereof. The method comprises forming droplets of the liquid solution including the structural units, and spraying the droplets on a substrate, thereby substantially increasing the reactivity of the structural units within the droplets relative to the structural units within the liquid solution in the spray head. The increase in reactivity can result from the droplets containing an excess of a particular ion, the ion excess resulting from a voltage applied to conductive walls of the device which dispenses the droplets. The material structure is then formed on the substrate from the more highly reactive structural units within the droplets.

In a first coating step, low electrical conductivity is imparted to a coating surface 21 of a non-electrically conductive coating object 20 and a first paint film is formed by applying a charged first paint to the coating surface 21 with free ions being suppressed. In a second coating step, a second paint film is formed by applying a negatively-charged second paint to a surface of the first paint film with free ions being suppressed, before the first paint film dries.
