Abstract:
Structures comprising a first sheet of perforated two-dimensional material and a first plurality of spacer elements disposed between a surface of the first sheet of perforated two-dimensional material and at least one of a surface of a structural substrate and a surface of a second sheet of perforated two-dimensional material are disclosed, as well as related methods. The structures may further comprise a structural substrate, a second plurality of spacer elements, additional sheets of perforated two-dimensional material in direct contact with the first and/or said second sheet of perforated two-dimensional material and/or relief features in the surface of the structural substrate.
Abstract:
A filtration and selective fluidic recovery device comprises a housing having an inlet and an outlet. The housing has an opening extending from the inlet to the outlet and an internal support structure maintained in the opening. Planar graphene membranes (122,130) with different selectivities are carried by the internal support structure (106) where the media separates feedwater received at the inlet into two different permeates (114,116) and a concentrate (112) that separately exit at the outlet. Optonal switchable voltage supply for fouling prevention.

Abstract:
A tunable membrane configuration (10) for a filtration or selective fluidic isolation and recovery device includes a housing (12) having an inlet at one end and an outlet at an opposite end with an opening extending from the inlet to the outlet. An internal support structure is maintained in the opening and layered filtration media comprising graphene membranes (42/43) is carried by the internal support structure the media separating feedwater received at the inlet into at least three separate output flows (26 28 30). Concentration polarisation (84) and pore size (55) can be controlled via an electrical charge control (78).
