Abstract: An ion-exchange composition suitable for use in ion exchange chromatography, comprising neutral vinyl polymer support particles irreversibly bound to a dispersant having ionizable sites which are un-ionized at a neutral pH and which are ionized under highly acidic or highly basic conditions, and fine layering particles functionalized with ion-exchanging sites on the surfaces thereof. A portion of the ionizable sites are ionized and bound electrostatically to a portion of the fine layering particles ion-exchanging sites, producing a support particle-dispersant-fine layering particle complex.

Abstract: The present disclosure relates, in some embodiments, to a method including demineralizing a protein liquor (i.e., a liquid portion of a lysed microcrop (e.g., Lemna) that has been separated to generate the liquid portion and a solid portion and having a composition including a soluble microcrop protein and a Vitamin B12) to generate a demineralized protein liquor. According to some embodiments, demineralizing the protein liquor may include diafiltration, ultrafiltration, nanofiltration, reverse osmosis filtration, electrodialysis, and/or passing the protein liquor through an ion exchange resin (e.g., an anion exchange resin. a trialkyl ammonium salt having three methyl groups). In some embodiments, a method may further include concentrating a demineralized protein liquor to generate at least one of a milk base and an electrolyte drink.

Abstract: Provided are a monovalent anion selective ion exchange membrane and a method of manufacturing the ion exchange membrane. In regard to the monovalent anion selective ion exchange membrane, a surface portion thereof has a high amount ratio of a cation exchange polymer electrolyte, a central portion thereof has a high amount ratio of an anion exchange polymer electrolyte, and an amount ratio of the anion exchange polymer electrolyte with respect to the cation exchange polymer electrolyte continuously increases in the thickness direction thereof from the surface toward the center. Due to this structure, compared to monovalent anions, polyvalent anions may permeate much less through the exchange membrane. Thus, high selectivity for monovalent anions may be obtained.

Abstract: The present disclosure relates to water purification compositions and the method of producing the same. Specifically, the present disclosure relates to compositions containing a substrate that has hydroxyl, thiol, carboxyl or amino groups, a metal oxide, and a carboxylic acid compound, and the method of producing the same. The composition is useful for the removal of soluble phosphorus, selenium, fluoride, arsenic and other heavy metal contaminants that may be present in water. The composition could be of use in numerous fields, including but not limited to, oil and gas, mining, storm water, agricultural runoffs, municipal wastewater, and industrial wastewater.

Abstract: The present invention provides a new chemical process, a new cassette configuration, and new software for the automated production of multiple batches of an [18F]labelled compound on a single cassette. The invention allows one synthesizer in one hot cell to produce sequentially a plurality of batches of [18F]-labelled PET tracer in the same day. In particular, the present invention provides a novel arrangement useful for the trapping of [18F]fluoride and recovery of [18O]water.
