An article Including a support matrix including a plurality of pores, a metal oxide and a clay, wherein the metal oxide and the clay are disposed on the support matrix or within the plurality of pores of the support matrix, and a method of removing a hydrocarbon fluid and microplastics from an aqueous fluid by immersing the article into the aqueous fluid.

Copper based nanoparticle composite compositions, methods, and systems for purification and sterilization of contaminated water are provided.

The present invention relates to the extraction of lithium from liquid resources such as natural and synthetic brines, leachate solutions from minerals, and recycled products.

A filtration device selectively removes hydrophobic waste from wastewater while leaving other water and surfactant components, which may then be recycled to a point of use. The wastewater treatment system may comprise a filtration unit and filtration media. The filtration unit may comprise a housing having an inlet in fluid communication with an outlet of a point of use and configured to receive a wastewater stream from the point of use for treatment, and an outlet in fluid communication with an inlet of the point of use and configured to deliver filtrate to the point of use. The filtration media may be positioned within the housing. The filtration media may comprise an oleophilic foam substrate and a hydrophobic coating on the oleophilic foam substrate. The filtration media may be configured to separate a hydrophobic component from the wastewater stream to produce filtrate comprising water and surfactant.

A sorbent material is disclosed for the one-step separation of bio-macromolecules in a single pass extraction of DNA from complex mixtures of molecules and chemicals. In one embodiment, the sorbent material comprises a silanized material at least partially coated or formed with a polymer selected from the group consisting of a poly(aryl methacrylate), a poly(aryl acrylate), a poly(heteroaryl methacrylate, a poly(heteroaryl acrylate) and a copolymer thereof.

Disclosed are water-absorbent resin particles comprising a crosslinked polymer comprising a monomer unit derived from a water-soluble ethylenically unsaturated monomer, wherein an initial swelling force as measured according to a swelling force test conducted by a predetermined method is 8 N or more, and further, a ratio of the particles having a particle diameter of more than 250 μm and 850 μm or less is 70% by mass or more and a ratio of the particles having a particle diameter of 250 μm or less is 20% by mass or less, with respect to the total amount of the water-absorbent resin particles.

Disclosed is a composite of a particulate and polymer, the composite characterized by less than enough polymer to fully occupy the available excluded volume of the particulate of the composite. The resulting composite is characterized by the particulate partially covered by the polymer leaving a substantial surface area uncovered.

A wash buffer comprising a surfactant for use in affinity and cation exchange chromatography to purify proteins of interest from protein aggregates and to remove and/or inactivate viruses. When used during affinity or cation exchange chromatography for the purification of a protein of interest, such as an antibody, the wash buffer significantly improves viral clearance from the preparation, while also reducing the levels of host cell proteins and protein aggregates. Following affinity or cation exchange chromatography with the wash buffer, the protein of interest may be further purified using other chromatography and filtration operations.

Filter media and filters for the sequestration of carbon dioxide are disclosed. The carbon dioxide sequestering filter media incorporate silicate minerals, and the carbon dioxide sequestering filters incorporate carbon dioxide sequestering filter media. Filters using only carbon dioxide sequestering media and filters combining carbon dioxide sequestering media with traditional air filter media are disclosed. The carbon dioxide sequestering filters may be used instead of traditional air filters in residential, commercial and industrial applications.

Described herein are passive samplers, making of such samplers, and methods of use. In an example embodiment, a passive sampling membrane comprises, for example, a continuous mesoporous sequestration media having a sequestration phase and a support membrane configured to support the sequestration phase. The sequestration phase may include a hydrophobic region and a hydrophilic region. The continuous mesoporous sequestration media may be configured to simultaneously sequester polar and non-polar organic substances.
