Solid material having an open multiple and at least partially interconnected porosity, comprising an inorganic matrix made of a microporous and mesoporous geopolymer, in which at least partially interconnected open macropores delimited by sides or walls made of microporous and mesoporous geopolymer are defined, and particles of at least one solid compound different from the geopolymer being distributed in the macropores and/or in the sides or walls. Method for preparing said material. Method for separating at least one metal or metalloid cation from a liquid medium containing it, wherein said liquid medium is placed in contact with the material.

Method for lowering aldehyde content in a mixture comprising (i) diethylene glycol (DEG) and/or triethylene glycol (TEG) and (ii) aldehyde are disclosed. An ion exchange resin is soaked in monoethylene glycol. The mixture comprising 5 to 200 ppm aldehyde is then flowed to make contact with the soaked ion exchange resin to produce a product comprising DEG and/or TEG and less than 15 ppm aldehyde.

The problem to be solved is to deal with infectious diseases caused by pathogens that invade from the outside with ventilation to the cultivation room and adhere to the leaf surface or float in the cultivation room.

A silicate clay ore is powdered, and the powdered clay ore is mixed with water and stirred to prepare suspension water or its supernatant water. The present invention proposes a method of atomizing into a cultivation room using an atomizer capable of generating an air flow having a predetermined momentum.

Adsorptive media for chromatography, particularly ion-exchange chromatography, derived from a shaped fiber. In certain embodiments, the functionalized shaped fiber presents a fibrillated or ridged structure which greatly increases the surface area of the fibers when compared to ordinary fibers. Also disclosed herein is a method to add surface pendant functional groups that provides cation-exchange or anion-exchange functionality to the high surface area fibers. This pendant functionality is useful for the ion-exchange chromatographic purification of biomolecules, such as monoclonal antibodies (mAbs).

The invention relates to a liquid sample preparation device such as a disposable, collapsible, flexible polymeric bag containing an adsorptive curtain of a functionalized shaped polymeric fiber bed for the direct capture of biomolecules from liquid samples. The functionalized shaped polymeric fiber bed includes fibrillated, ridged or winged-shaped fiber structures that significantly increases the surface area of the fiber resulting in enhanced separation, retention and/or purification of liquid samples containing biomolecules of interest as the liquid samples contact the adsorptive curtain of functionalized shaped fibers. Liquid samples include unclarified liquid feeds or other liquids containing one or more biomolecules of interest, including, but not limited to vaccines, recombinant proteins, cells, stem cells, monoclonal antibodies (mAbs), proteins, antibody, peptides, oligopeptides, nucleic acids, oligonucleotides, RNA, DNA, oligosaccharides and polysaccharides.
