A Co.sub.2O.sub.3Bi.sub.2O.sub.3@SiO.sub.2 nanocomposite material includes Co.sub.2O.sub.3Bi.sub.2O.sub.3@SiO.sub.2 nanocomposite particles having a granular morphology with an average diameter in a range from 10 to 30 nanometers (nm). The Co.sub.2O.sub.3Bi.sub.2O.sub.3@SiO.sub.2 nanocomposite material has a Brunauer-Emmett-Teller (BET) surface area of greater than or equal to 70 square meters per gram (m.sup.2.Math.g.sup.1). The Co.sub.2O.sub.3Bi.sub.2O.sub.3@SiO.sub.2 nanocomposite material has an adsorption capacity for ciproflaxin of greater than or equal to 70 milligrams per gram (mg.Math.g.sup.1).

A method for producing a VOC adsorption device, the method including: mixing a VOC adsorption material, a solvent, a binder, and resin beads to form a slurry; coating the slurry on a substrate; and firing the substrate coated with the slurry at a temperature higher than a thermal decomposition temperature of the resin beads.

Disclosed are textile fibers, yarns, and fabrics having improved comfort and water and odor adsorption properties, and methods of manufacturing same. The improved textiles have an increased distribution of adsorbing particles distributed at the surface of the fibers and yarns to enable greater overall surface area for adsorbance.

An example method includes receiving saline water at a desalination tank, the desalination tank including a porous substrate impregnated with metal particles in a fixed position within the desalination tank, contacting the saline water with the porous substrate to remove impurities from the water, thereby forming treated water, and outputting the treated water.

The present invention relates to a method of preparing an adsorbent for removing radon. The method includes (a) mixing a fluorine (F) compound and zeolite to produce a second mixture.
