The invention relates to alkenyl(perfluoroalkyl)phosphinic acids, to the preparation and intermediates thereof, to the use thereof as monomers for the preparation of oligomers and/or polymers, to the corresponding oligomers/polymers, to the corresponding support materials comprising the oligomers/polymers, and to the use thereof as ion exchangers, as catalysts or extraction medium and corresponding salts thereof.

Disclosed herein are methods and compositions for purifying proteins from crude solutions.

Novel porous materials comprising nanoparticles, use in chromatographic separations, processes for its preparation, and separations devices containing the chromatographic material are described by the instant invention. In particular, the disclosure describes porous inorganic/organic hybrid particles embedded with nanoparticles selected from oxides or nitrides of the following: silicon carbide, aluminum, diamond, cerium, carbon black, carbon nanotubes, zirconium, barium, cerium, cobalt, copper, europium, gadolinium, iron, nickel, samarium, silicon, silver, titanium, zinc, boron, and mixtures thereof.

Provided are a carrier for a dry adsorbent for carbon dioxide, including spherical silica whose surface is engraved in the form of nanowires, and a method for preparing the same. Although the carrier for a dry adsorbent for carbon dioxide including spherical silica that has nanowires on the surface thereof has a very non-uniform shape, it serves better as a host structure adsorbing carbon dioxide as compared to the conventional carrier for a carbon dioxide adsorbent, and thus may be used for a host-guest adsorbent applicable to a fluidized bed process. In addition, the method for preparing a carrier for a carbon dioxide adsorbent provides nanowire-coated silicon spheres having an increased surface roughness and an increased surface area, thereby providing increased carbon dioxide capturing efficiency. Further, since the method for forming nanowires is simple, it is easy to carry out mass production without any separate process, thereby providing excellent cost efficiency.

Adsorbent materials comprising a core, for example CHA, and at least one coating, for example DDR, are provided herein. Adsorbent contactors and gas separation processes using the adsorbent materials are also provided herein.

Disclosed is a device for a solid phase extraction comprising two or more of the sorbents to remove phospholipids and salts from a sample, to thereby eliminate matrix effects during mass spectrometry analysis. In particular, the sorbents includes at least one sorbent which is water-wettable and contains at least one hydrophobic component and at least one hydrophilic component and at least one of sorbent having a specific affinity for a matrix interference like phospholipids. Further disclosed is a method using the device of the present invention.

A material for moisture removal and/or water harvesting from air may include a hydrophilic material containing micropores and a low water activity material confined within the micropores of the hydrophilic material. Apparatuses containing such materials and methods for moisture removal and/or water harvesting from air by using such materials are also described.

Method for manufacturing an inert solid support with optionally functionalised carbon nanotubes (CNTs), comprising the steps of: i) providing an inert solid support and at least one catalytic metal associated with, or absorbed in, or adsorbed/deposited on, said support, said metal being optionally selected from among the group consisting of iron, cobalt, nickel, molybdenum and combinations thereof; ii) supplying a source of gaseous, liquid or solid carbon to the catalytic metal; iii) through chemical vapor deposition (CVD), depositing at least part of the carbon source at the catalytic metal as CNTs, stably connected to the inert solid support. The present invention further regards an inert solid support and a separation method.

The present invention concerns a zeolitic adsorbent comprising a zeolitic agglomerate comprising at least one zeolite and at least one agglomeration binder, said agglomerate being coated with a coating comprising at least one pigment.

The present disclosure discloses an efficient and regenerable nano manganese remover, and a method for preparing same and application thereof, belonging to the technical field of wastewater treatment and reuse. The manganese remover of the present disclosure includes Fe.sub.3O.sub.4, RGO, SiO.sub.2 and EDTA. The Fe.sub.3O.sub.4 nanoparticles are supported on the surface of the RGO, the SiO.sub.2 coats the Fe.sub.3O.sub.4, and the EDTA is grafted on the SiO.sub.2. First, Fe.sub.3O.sub.4-RGO is prepared. Then, a TEOS-ethanol solution is dropwise added, and the resulting mixture is allowed to react to obtain Fe.sub.3O.sub.4@SiO.sub.2-RGO composite particles. Finally, an EDTA-water solution is dropwise added to obtain the manganese remover. The manganese remover prepared in the present disclosure is magnetic, and the preparation process is simple and easy for industrial production. The nano manganese remover can quickly remove manganese in manganese-containing wastewater. A small amount of the manganese remover can achieve a large adsorption capacity. Further, the nano manganese remover can be separated from the manganese-containing wastewater quickly, thereby avoiding secondary pollution to the system.
