Abstract: The present disclosure provides methods for producing carboxylated nanocelluloses. Compared with conventional methods, the methods of the present disclosure are simple and cost-effective in the production of carboxylated (or carboxy) nanocelluloses, in embodiments nanofibers and/or nanowhiskers, directly from raw biomass, including lignocellulose wood, non-wood sources, non-lignocellulose wood, lignocellulose or pure cellulose. The carboxy groups on the surface of nanocellulose thus produced can then be easily modified into functional derivatives such as amide, acetate, ether, ester, etc. The resulting nanocelluloses may be used to form purifying agents and/or filters to remove impurities from wastewater.

Abstract: Membranes are provided for filtering a gas, in some cases air. Membranes using a highly porous cellulose nano fibrous barrier layer with a highly porous (surface-charged) substrate can exhibit high flux, high retention, and low pressure drop in air filtration of toxic aromatic gases, fumes, bacteria, viruses, dusts, and particulate matters.

Abstract: Articles are provided for absorbing fluids. In embodiments, the articles of the present disclosure are modified to make them hydrophobic, thereby decreasing their affinity for water and similar liquids, while increasing their affinity for other hydrophobic materials, including oil. After use, the articles, in embodiments sponges, may have their absorbed materials removed therefrom, and the articles may then be re-used to absorb additional materials.
Abstract translation: 提供用于吸收流体的物品。 在实施方案中，本公开的制品被修饰以使其疏水，从而降低它们对水和类似液体的亲和力，同时增加它们对其它疏水性材料（包括油）的亲和力。 在使用后，在实施方案中海绵的制品可以从其中除去其吸收的材料，然后可以将制品再次用于吸收额外的材料。
