The sequential infiltration synthesis (SIS) and Atomic Layer Deposition (ALD) of metal and/or metal oxides on personal medical equipment (PPE). The deposited metal and/or metal oxides imbues antimicrobial properties to the PPE.

An antimicrobial metallized thin film is provided that can be quickly and easily attached to surfaces of objects. This film includes a polymer substrate onto which a metallized layer is formed. The metallized layer comprises an exposed antimicrobial metal physical contact surface. Ions from this physical contact surface destroy the viral coating and ribonucleic acid of contacting viruses rendering the viruses inactive and noninfectious. The film can be attached via an adhesive layer disposed between and in contact with the polymer substrate and the communal surface. This arrangement allows the film to economically refurbish communal surfaces with a film overlay rather than completely replacing communal surfaces with antimicrobial materials. The film mitigates the likelihood of viruses such as coronaviruses, noroviruses, rhinoviruses, and the like from spreading due to contact with the refurbished communal surfaces.

A respiratory face mask having a breathing cartridge therein which face mask breathing cartridge can both filter the breathing air while passing the breathing air through a voltage being generated by the cartridge. The cartridge generates a galvanic cell using spaced apart dissimilar metal particles when immersed in an electrolyte being held by an adjacent hydration layer of liquid retaining foamed polymer having breathing passageways therethrough.

Provided are an interior material having a surface layer as a thin film with a high transparency and exhibiting deodorant and antimicrobial properties; and a production method thereof. The interior material has a surface layer containing (i) titanium oxide particles and (ii) antimicrobial metal-containing alloy particles. The interior material is such that an antimicrobial metal(s) contained in the (ii) antimicrobial metal-containing alloy particles is at least one kind of metal selected from the group consisting of silver, copper and zinc. The production method of the interior material of the present invention includes a step of applying a dispersion liquid containing the (i) titanium oxide particles and the (ii) antimicrobial metal-containing alloy particles to a surface of the interior material.

The deodorant dispersion of the present invention includes (A) two or more powdery inorganic chemical adsorbents, (B) a dispersing agent, and (C) a dispersion medium, a content proportion of the component (A) is in a range from 10% to 30% by mass based on a total of the deodorant dispersion, a content proportion of the component (B) is in a range from 1% to 10% by mass based on a total of the deodorant dispersion, and a median particle diameter of a dispersoid is in a range from 0.1 m to 0.4 m. A gas adsorption capacity of the component (A) is preferably 25 mL/g or more.

Provided a deodorant composition including dispersed particles which have an average secondary particle diameter of 200 nm or less and are formed of at least one kind of particles selected from metal particles or metal oxide particles and each of which has a surface that does not contain a dispersant; and at least one kind selected from an aqueous solvent other than water or a metal salt having a monovalent, a divalent, or a trivalent metal ion.

A treatment system, including a conveyor bed configured to transport a plurality of products; a brushing device located along the conveyor bed and having one or more brushes that include a first antimicrobial compound; a surface treatment device including a lamp configured to emit light of a peak wavelength directed toward a portion of the conveyor bed; and a coating device configured to deliver a coating mixture onto the plurality of products on the conveyor bed.

A method for treating foul odors. A chemical solution is administered to the area to be treated. The chemical solution includes: potassium iodine, zinc sulfate and magnesium sulfate. In a preferred embodiment the chemical solution is diluted in water and applied to an area needing treatment.
