A geomaterial web includes a first organic structural material and a second structural material that is different from the first structural material, which is bonded together with the first structural material to form a sheet-like composite material web extending in two mutually perpendicular directions. The first structural material and the second structural material are organic materials, where the first structural material has a first biodegradability and the second structural material has a second biodegradability that is different from the first biodegradability. The second biodegradability may be less than the first biodegradability.

Provided is graphene-based personnel protection equipment (PPE) product, comprising: (a) a fabric, clothing, face shield, face mask, or glove body configured to support graphene sheets; and (b) graphene sheets deposited on a surface of the body or at least partially embedded in the body, wherein the graphene sheets comprise a plurality of discrete single-layer or few-layer graphene sheets selected from pristine graphene, graphene oxide, reduced graphene oxide, graphene fluoride, graphene chloride, graphene bromide, graphene iodide, hydrogenated graphene, nitrogenated graphene, doped graphene, chemically functionalized graphene, or a combination thereof. Preferably, surfaces of graphene sheets carry an anti-microbial compound, preferably in the form of a nanoparticle, nano-wire, or nano-coating.

Disclosed herein is a degradable filter structures and protective coverings including degradable filter structures. The filter structures comprise cellulose acetate and optionally plasticizer. The filter structures and protective coverings described herein degrade more rapidly than other known protective coverings.

A fluid control device includes a support structure configured to be deployed to a selected location in a borehole, and a filtration medium disposed at the support structure and configured to filter a fluid, the filtration medium configured to be compacted from an initial shape to a compacted shape prior to deployment in the borehole. The filtration medium includes a first polymeric material configured to withstand a temperature at the selected location, the first polymeric material forming a porous structure including a plurality of fluid passages, and a second polymeric material including a shape memory polymer disposed within the fluid passages, the shape memory polymer configured to expand in the plurality of fluid passages and cause the filtration medium to expand in the borehole.

The method for producing a nanocellulose support comprises coating a container with surface-treated nanocellulose solution, forming a nanocellulose film by drying the coated nanocellulose solution, and modifying the surface properties of the nanocellulose film by means of electron beam irradiation. According to an embodiment, the production of nanocellulose supports using the drying method allows substrates of various shapes to be coated and has simple processes, thus allowing mass production and production of over-sized supports.

A pool strainer basket insert system and method are contemplated in which a high porosity, coarse fibrous mass is inserted in a pool skimmer basket. Via optimization of the material properties of the fibrous mass and configuration such that approximately 50% of the fibrous mass is located above the waterline and 50% below the water line the problems of the prior art may be solved via the retaining properties of the fibrous mass, enabling insects and small organic matter to be retained and preventing their migration back to the main body of the pool.

An apparatus for collection and disposal of fats, oil and grease that includes a fabric container having at least one open end, a biogradable material capable of absorbing a large quantity of fats, oil and grease positioned in the container through the open end, the container and biogradable material adapted for being placed in a source of fats, oil and/or grease for absorbing the fats, oil and/or grease for removal from the source and for transport to a location for processing.

A method of forming a biofuel by capturing fats, oils, and/or greases in a grease trap is described. The method includes adding an absorbent material to a grease trap to absorb fats, oil, and/or greases, forming a biofuel by absorbing the fats, oils, and/or greases over time, removing the formed biofuel from the grease trap, and optionally transporting the biofuel for storage and/or incineration. The absorbent material, which may be stored in a porous fabric container in the form of a tube or a mat, includes: sphagnum peat, mushroom compost, orange peels, and/or polypropylene.
