Chromatography devices contain chromatography media and methods of making and methods of using chromatography devices. Chromatography devices enable a more efficient, productive and/or environmentally friendly chromatographic operation due to one or more of the following advantages over conventional chromatographic operations: elimination of a device packing step by the user; elimination of clean-in-place (CIP) steps; elimination of clean-in-place (CIP) steps utilizing sodium hydroxide solution; elimination of any validation steps by the user; and use of a chromatography device comprising biodegradable material. The chromatography media includes porous inorganic particles having a functionalized surface and having a median pore size of at least about 300 Angstroms (A), or at least about 300 A up to about 3000 A. The inorganic particles may have a BET surface area of at least about 20 m2/g, or at least about 25 m2/g, or about 30 m2/g, up to about 2000 m2/g.

A process for the efficient transfer of molecules between phases employing mesoporous poly (aryl ether ketone) hollow fiber membranes is provided. The method addresses the controlled transfer of reactants into and removal of reaction products from a reaction media and the removal and separation of target molecules from process streams by membrane-assisted liquid-liquid extraction. A number of possible modes of liquid-liquid extraction are possible according to the invention by utilizing porous poly (aryl ether ketone) hollow fiber membranes of Janus-like structure that exhibit a combination of hydrophilic and hydrophobic surface characteristics. The method of the present invention can address the continuous manufacture of chemicals in membrane reactors and is useful for a broad range of separation applications, including separation and recovery of active pharmaceutical ingredients.

A graphene coated crushed glass particle adsorbent is provided for the removal of heavy metals and other contaminants in from solutions such as wastewaters, contaminated surface water and groundwater. The adsorbent comprises crushed (e.g. recycled) glass coated with graphene nano-sheets using a staged thermal binding process and the silicas in the glass as a catalyst. The adsorbent may be configured for use in both in-situ and ex-situ treatment systems and is capable of removing heavy metals and other inorganic and organic contaminants. The strong adsorptive bond between contaminants and the graphene coating on crushed glass particles can also lead to alternative applications of the end of life adsorbent, such as base material in road and pavement (e.g. cement-like) construction materials.

A composition for treating water including an organic soil amendment and having ions bound thereto is beneficial to aid in the removal of aqueous contaminants, such as phosphate, other phosphorus containing compounds, arsenic, arsenic containing compounds, fluorides, and PFAS from water. In these compositions the ions include rare earth cations, iron cations, and mixtures thereof. There are also methods for making these soil amendment compositions, as well as methods for using these compositions to effectively remove contaminants from water.

Yttria containing hybrid organic-inorganic sol-gels may be used in coatings for capillary microextraction, optionally hyphenated to online HPLC analysis. The sol-gel reaction mixture can use an yttrium trialkoxyalkoxide, such as yttrium trimethoxyethoxide, and a [bis(hydroxyalkyl)-amino-alkyl]-terminated polydialkyl/arylsiloxane, such as [bis(hydroxyethyl)-amine] (BHEA)-terminated polydimethylsiloxane, that can undergo hydrolysis and polycondensation, to form coating materials. Capillaries coated with such sol-gels can have improved extraction efficiency compared, e.g., to pure yttria-based coatings. The CME-HPLC can analyze water samples containing analytes of varied polarity, with excellent extraction of amides, phenols, alcohols, ketones, aldehydes, and polyaromatic hydrocarbons and detection limits ranging from 0.18 to 7.35 ng/mL (S/N=3). Such capillaries can exhibit solvent stability at pH 0 to 14, RSD % between 0.6 to 6.8% (n=3), at a preparative reproducibility RSD between 4.1 and 9.9%.

There is disclosed a relatively simple method to increase the performance of surface localised multi-valent affinity ligands whose target's isoelectric pH differs significantly from the ligand's optimal target-binding pH. This situation can result in ligand binding of target affecting local pH and subsequent binding of more target. Increasing the buffering capacity of the ligand via recombinant or other addition of charge groups to the ligand is expected to partially offset such effects, leading to enhanced binding capacity as well as possible secondary favourable alterations in regard to ligand elution pH, and non-specific surface binding of non-target proteins.

The present invention relates to a method and apparatus for providing and/or receiving audible sound. In particular, the invention relates to apparatus, such as a micro speaker, which includes an active region which comprises an adsorbent element in the form of a self-supporting monolith-like element with a porous reticulated structure. The adsorbent element includes adsorbent material which comprises microporous organic polymer (MOP) material. The apparatus of the present invention is suitable for use in an electronic device, for example a mobile or portable electronic device, to provide improved audible sound.
