Abstract: Articles including poly(2,2,3,3,4,4,4-heptafluorobutyl methacrylate) or poly(2,2,3,3,4,4,4-heptafluorobutyl acrylate), fluoropolymers that do not form perfluorooctanoic acid (PFOA) when they degrade and that exhibit unexpectedly good oil repellency, are described. A method of making a fluoropolymer-containing article includes depositing a fluoropolymer-liquid mixture onto porous filtration medium by contacting the porous filtration medium with a mixture comprising a fluoropolymer and a liquid to form the treated porous filtration medium; and removing the liquid. The fluoropolymer includes poly(2,2,3,3,4,4,4-heptafluorobutyl methacrylate) or poly(2,2,3,3,4,4,4-heptafluorobutyl acrylate). Methods of using the article are further described.

Abstract: This disclosure describes compositions including a perfluoropolyether (PFPE) bottlebrush polymer, optionally blended with other fluoropolymers. The compositions may be disposed on an article, including, for example, a porous filtration media, to form a fluoropolymer-containing article. This disclosure further describes methods of making fluoropolymer-containing articles and methods of using the fluoropolymer-containing articles.

Abstract: The current technology relates to substrate treatments, treated substrates, and filters. Treated substrates can have a treated surface that defines a pattern and/or gradient among untreated surface areas. A treated surface area can have a higher roll off angle for a 50 μL water droplet when the surface is immersed in toluene that the untreated surface areas. Substrates can be treated by, for example, exposing a substrate surface and/or fibers to ultraviolet (UV) radiation. UV radiation can be applied to surfaces via a mask, lens, waveguide, reflector, as examples. UV radiation can be applied to surfaces at varying intensities, which can create a treatment gradient.

Abstract: The present application discloses a cassette assembly including an inlet cassette plate, an outlet cassette plate, and a separation layer disposed therebetween. The inlet cassette plate defines an inlet flow path and an inlet channel extending therefrom. The outlet cassette plate is configured to be arranged in a stack with the inlet cassette plate and defines an outlet flow path and an outlet channel extending therefrom. The separation layer extends from a first lateral end to a second lateral end. The inlet flow path is configured to be in fluid communication with the outlet flow path through the separation layer. The inlet channel defines an effective inlet surface area of the separation layer and the outlet channel defines an effective outlet surface area of the separation layer. The effective inlet surface area defines a first width towards the first lateral end and a second width towards the second lateral end.

Abstract: A vent assembly having a housing (106) defining a cavity (202), a first end (102) and a second end (104), where the second end includes a coupling structure (108). The first end defines a window (110) in fluid communication with the cavity, wherein the window has a window perimeter. The vent assembly includes a vent media (206) spanning the cavity of the housing, where the vent media is breathable and forms a watertight seal to the housing at a perimeter of the vent media. The first end includes a screen structure (300) within the window perimeter of the window that can include repeating structures defining open areas.

Abstract: A system for separating a solvent includes a first mixing tank comprising a waste solvent feed and a reactant feed; a first filter comprising a nanofiltration membrane; a distillation column or an evaporator; a condenser or cooler; and a pervaporation membrane. A method for separating a solvent includes mixing a waste solvent with a reactant to cause precipitation or complexing and forming a mixture; filtering the mixture using a nanofiltration membrane and forming a permeate; distilling or evaporating the permeate to form a concentrated solvent; condensing or cooling the concentrated solvent to below a boiling point of solvents in the concentrated solvent; and filtering the concentrated solvent using pervaporation to form a purified solvent. The system and method may be used to separate and purify a solvent without creating thermal degradation products.

Abstract: A system for producing steam includes a source of superheated water with superheated water output; a membrane filtration system in fluid communication with the superheated water output and including a membrane filter with a permeate side and an opposing retentate side. The membrane filter includes a separation membrane constructed to reject organic molecules. The system may be used for removing organic compounds, such as anti-corrosion agents or contaminants, from superheated water to produce steam. A method for producing steam includes directing a cross-flow of heated pressurized water including a first concentration of an organic compound across a membrane filter. The membrane filter includes a separation membrane constructed to reject the organic compound; and one or more support layers adjacent the separation membrane. A steam permeate including a second concentration of the organic compound is collected, where the second concentration is lower than the first.
