Abstract: Provided is a carbon dioxide absorbent including an ionic liquid including an imidazole-based anion and an aliphatic alcohol, and since an alcohol solvent included in the carbon dioxide absorbent according to one embodiment has low toxicity and a very high boiling point, the carbon dioxide absorbent has no problem of release into the atmosphere and consequent environmental pollution, and is chemically stable to significantly lower the possibility of release of decomposition products into the atmosphere. In addition, the carbon dioxide absorbent is also effective, since it may absorb carbon dioxide with a higher equivalent than an absorbent input equivalent, and has low regeneration energy so that carbon dioxide is easily desorbed.

Abstract: A chromatography medium is provided, comprising a matrix of cellulose-based nanofibers, the nanofibers optionally being crosslinked to one another. A ligand coupled to the matrix without any intermediate extender group. Also provided is a method of preparing a functionalised chromatography medium. The method comprises: (i) providing a substrate comprising cellulose acetate; (ii) forming a fibrous matrix/membrane spun of nanofibers from the substrate; (iii) saponification of the nanofibers to form regenerated cellulose nanofibers; (iv) derivatisation of the regenerated cellulose nanofibers with a cross-linker, and (v) coupling of a ligand to the derivatised cellulose nanofibers, wherein the preparation of the functionalised chromatography medium does not comprise any surface extender. The chromatography medium is useful for separation of large analytes, such as viruses.

Abstract: The present inventive concept relates to an aluminosilicate structure body with a novel crystal structure and, more specifically, to an aluminosilicate structure body having a novel crystal structure and a skein-shaped morphology, a method for preparing the same, and an HPLC column filled with the same as a stationary phase. The aluminosilicate structure body according to the present inventive concept has a novel crystal structure and a skein-shaped morphology, and thus has a specific surface area increased to up to 300 m2/g so as to improve separation ability; and does not undergo a structural change with pH changes, and thus can be usefully used in a wider range of pH conditions than existing silica gel which has been conventionally used as a stationary phase for HPLC columns.

Abstract: An adsorption system having at least one adsorber retaining a bed of adsorbent material can be configured to provide enhanced purification of fees having relatively low concentrations of hydrogen or helium. Embodiments can utilize an activated carbon layer between at least one upstream layer and at least one downstream layer. The activate carbon layer can include activated carbon can have a pre-selected surface area (SA), bulk density, total open pore volume (TOPV), and/or ratio of TOPV to surface area (TOPV/SA).

Abstract: A carbon dioxide capture structure having a monolithic three-dimensional shape, the structure being porous with interconnected pores which are accessible from an exterior side of the structure. The structure is made of a building material including a first material and a second material. The first material is a sorbent material (e.g. functionalizable for carbon dioxide adsorption). The second material is a binder material including potassium silicate. The present disclosure also relates to a method of making the carbon dioxide structure and a method for removing carbon dioxide from a gas or fluid mixture.
