Abstract: Polypropylene (PP) and polyethylene (PE) blends derived from plastic waste streams and a method to prepare reusable oil sorbents. A method includes separating plastics of group-A from group-B using a float-sink technique, where group-A comprises various PP and PE materials, and group-B comprises polystyrene, polyethylene terephthalate, and polyvinyl chloride; dissolving the group-A plastics in a solvent; adding a cavity forming agent to the solution; applying the solution onto a solid substrate through spin-coating followed by controlled heating; and extracting the cavity forming agent, obtaining a thin film sorbent with swellable cavities for oil sorption. The film contains 400-800 swellable 3D cavities/cm2, each cavity capable of swelling 20-30 times the thickness of the film when contacted with oil. The method improves compatibility of PP-PE blends without using compatibilizers, resulting in high oil uptake capacity due to swellable cavities, and reusability of sorbent with an oil recovery of more than 98%.

Abstract: In one aspect, the present invention provides a chromatographic stationary phase material for various different modes of chromatography represented by Formula 1: [X](W)a(Q)b(T)c (Formula 1). X can be a high purity chromatographic core composition having a surface comprising a silica core material, metal oxide core material, an inorganic-organic hybrid material or a group of block copolymers thereof. W can be absent and/or can include hydrogen and/or can include a hydroxyl on the surface of X. Q can be a functional group that minimizes retention variation over time (drift) under chromatographic conditions utilizing low water concentrations. T can include one or more hydrophilic, polar, ionizable, and/or charged functional groups that chromatographically interact with the analyte. Additionally, b and c can be positive numbers, with the ratio 0.05≤(b/c)≤100, and a≥0.

Abstract: A porous material structure and device are described and shown to enhance the mass transfer and/or heat transfer at low pressure drops for removal of certain molecular species from a fluid by adsorption and/or catalytic reaction. The porous structure of active materials comprising packed fine particles of adsorbents or catalysts is encapsulated with a thin membrane to provide large interfacing area with the fluid per unit volume for rapid mass transfer between the porous structure and fluid. The thin membrane also blocks particulate from getting into the porous structure of the active material. For the process involving significant heat of adsorption and/or reaction, the another surface of the porous structure of the active material is encapsulated with a thin non-permeable sheet to interface with a thermal fluid for rapid heat transfer between the porous structure and the thermal fluid. The device can be used for removal of CO2, moisture, and hydrocarbon molecules from a gas stream with rapid in-situ regeneration. The device can be used for removal of water from water-containing liquid fluids, such as solvents and oils. The device can be used for removal of bacteria, virus, salts, and molecular contaminants from one water simultaneously.

Abstract: The present disclosure is directed to a multi-functional composition including activated carbon that is useful for injection or other application into soil or groundwater for removal (e.g., via adsorption) of inorganic contaminants in a contaminated plume. The composition of activated carbon may include physical and chemical properties to enhance the mechanism of contaminant physisorption and chemisorption including enhanced electrostatic interactions with contaminants. The multi-functional composition may further include one or more second materials (e.g., contaminant-selective agents) which comprise one or more compounds that improve the activated carbon's ability to sequester or otherwise immobilize inorganic contaminants in a subsurface environment.
