Antibacterial and antiviral filtering device crossed by contaminated air used in separation processes comprises column structure of contiguous filter modules delimited by lateral surface at inlet and lateral surface at outlet.

BUSSO G

Ink useful for providing viral active or anti-microbial coating to substrate, comprises carrier, graphene or graphene oxide particles dispersed in carrier, and viral active or anti-microbial component adhered to graphene.

CHEN S W, DEVINE S, CHEN S, SANDWINTHROP C

Preparation of polygraphene membrane for desalinating salt water involves mixing graphite, sodium nitrate and potassium permanganate and hydrogen peroxide, centrifuging mixture, and acylating and polymerizing resulting graphene oxide sheets.

SALEH T A

Membrane for providing selective permeability in filtration applications, comprises sheet of graphene-based material having perforations with specified pore size, non-graphenic carbon-based material, and contact areas between materials.

Manufacturing carbonized fiber or graphene composite for use in water treatment, electrode carrier for energy storage, and supporter for all kinds of catalyst, involves stripping graphene oxide chemically.

SOO J P, MI H C

Formation of membrane for e.g. separating water from water/oil emulsion, involves dispersing graphene oxide nanoparticles in solvent, depositing graphene oxide nanoparticles on support, and reducing obtained graphene oxide membrane.

YU M

Deionizing fluid carrying unwanted ions involves applying pressurized fluid to first surface of perforated graphene in cylindrical form, so that fluid flows to second side of the sheet in preference to ions; and collecting the fluid.
