The hybrid nanoporous membranes are assembled from inorganic 3D nanospiky particles and polymers, and can be used to filter, capture, and manipulate environmental or biological substances. These materials provide efficient, continuous filtration of ultrasmall biological substances with sizes less than 100 nm while still maintaining air or fluid flow through the materials.

A filter material of microspheres bonded in a close-packed arrangement is provided. A filter device comprising a funnel containing a filter material of microspheres bonded in a close-packed arrangement is provided. The filter material and filter device are suitable for plasma separation from whole blood.

A magnetic response fiber material and a preparation method and an application thereof are provided, which relates to the field of oil-water separation materials. The preparation method includes: mixing a fiber-forming polymer, a primary solvent, a secondary solvent and magnetic nanoparticles to form a uniform spinning solution, where the fiber-forming polymer includes at least one of polyethylene, polypropylene and polymethylpentene; spinning the spinning solution by a spinning process to obtain the magnetic response fiber material. The prepared magnetic response fiber material has the advantages of high oil absorption speed, high oil absorption capacity and high separation efficiency. Magnetic nanoparticles have a high load, which can not only be driven by magnetic force to absorb oil floating on water surface, but also be driven to an underwater oil pollution position to absorb oil, and can be applied to water purification in oil-polluted areas that cannot be reached by manual processing.

The present invention relates to a particulate filter, which comprises a substrate comprising a plurality of porous walls extending longitudinally to form a plurality of parallel channels extending from an inlet end to an outlet end, wherein a quantity of the channels are inlet channels that are open at the inlet end and closed at the outlet end, and a quantity of channels are outlet channels that are closed at the inlet end and open at the outlet end; and a layer of inorganic particles loaded on surfaces of porous walls in the inlet channels and/or outlet channels, wherein the layer of inorganic particles comprises inorganic particles having a small BET pore volume of no more than 0.5 cm3/g. The present invention also relates to a method for producing a particulate filter which includes applying inorganic particles or precursors thereof.

Described herein relates to an active force electric field anti-pathogenic fabric device and methods thereof used to remove pathogens from an environment surrounding the fabric. The device may be woven into daily clothing items, personal protective equipment, and/or other clothing items typically worn by a user. The device may include a current-carrying mesh that may be coated with active materials used to remove pathogens from the air. As such, the device may operate as an anti-pathogenic material that may be used to remove harmful particles from an area surrounding a user. Accordingly, microorganisms, smoke particles, industrial pollutants, odor molecules, and/or allergens may be structurally disassociated into harmless protein fragments and/or natural molecules when encountering the purifying agents in the device.
