Sorbent for a dialysis device and dialysis system
The invention relates to a sorbent for removing metabolic waste products from a dialysis liquid, the sorbent comprising a soluble source of sodium ions. The sorbent comprises an ion exchange system which converts urea to ammonium ions and which is configured to exchange ammonium ions for predominantly hydrogen ions and to exchange Ca, Mg, and K for predominantly sodium ions. The soluble source of sodium ions overcomes an initial drop in sodium concentration in regenerated dialysate. When used in conjunction with an infusion system configured to utilise exchange of Ca, Mg and K for sodium during dialysate regeneration a desired sodium ion concentration can be maintained.

Magnetic strong base anion exchange resin with high mechanical strength, and preparation method thereof
A magnetic strong base anion exchange resin with high mechanical strength and a preparation method thereof, belonging to the field of resin materials. The preparation method comprises steps of: adding a conventional strong base anion exchange resin to a mixture of trivalent iron salt and divalent iron salt, and then mixing the resin adsorbed with the iron salt with aqueous ammonia so that Fe.sub.3O.sub.4 nanoparticles are contained in the resin structure. Then, the resin containing Fe.sub.3O.sub.4 nanoparticles is added to alcoholic solution dissolved with silane coupling agent to form a dense SiO.sub.2 coating on the surface of the resin, so as to obtain magnetic strong base anion exchange resin with high mechanical strength.

STABILIZED ACYCLIC SACCHARIDE COMPOSITE AND METHOD FOR STABILIZING ACYCLIC SACCHARIDES AND APPLICATIONS THEREOF
Disclosed is a stabilized acyclic saccharide composite, which includes a LDH-based (layered double hydroxide-based) material and acyclic saccharides intercalated in interlayer regions of the LDH-based material. The acyclic saccharides stabilized and trapped in the LDH-based material give an opportunity for direct functionalization to other valuable molecules in the pharmaceutical, chemical or carbohydrate industries. Further, a novel pathway for saccharide transformation and aldol condensation without the drawbacks associated with enzymatic catalysts is achieved through the acyclic saccharides trapped by the LDH-based material.

Two-dimensional material for removal of anions and applications thereof
A method for preparing an anion adsorbent may be provided, which comprises the steps of: mixing at least two metal salts with each other, thereby forming a stack structure in which cationic compound layers and anionic compound layers containing anions and water of crystallization are alternately stacked on one another; performing a first heat treatment on the stack structure to expand between the cationic compound layers, thereby preparing a preliminary anion adsorbent; and performing a second heat treatment on the preliminary anion adsorbent to remove the anions and the water of crystallization from the anionic compound layers while allowing at least one of the anions to remain, thereby preparing the anion adsorbent.
