Abstract: A method of mitigating the environmental impact of invasive fish in rivers and lakes is provided. The method comprising recruiting overfishing of a species of fish harvested from one or more rivers or lakes in which the species of fish is invasive, obtaining fish bones from the harvested fish, producing a sorbent from the fish bones by drying and milling the fish bones into sorbent particles having a metal sorption capacity effective for treating a metal contaminated material, and treating metal contaminated material with an effective amount of the sorbent to form immobilized reaction products of the metal contaminated material and the sorbent.

Abstract: A method of treating contaminated water, such as wastewater, with carboxylated cellulose to remove ammonium and nitrogen-containing impurities is claimed. Carboxylated cellulose extracted by nitro-oxidation has negatively-charged functionality and forms an aggregate when exposed to positively-charged impurities in contaminated water. The aggregate, nitrogen-containing impurities, and by-products from the nitro-oxidation process can be isolated to provide a fertilizer or fertilizer component.

Abstract: A method of preparing an adsorbent can include pyrolyzing date pit to provide a date pit char, activating the date pit char, dissolving polyolefin waste in an organic solvent to obtain a solution, dispersing the date pit char in the solution to provide a mixture, extracting the solvent from the mixture to provide a composite, and annealing the composite to provide the adsorbent. The adsorbent can be porous.

Abstract: A multi-functionalized NPG nanosheet can be used to form a 3D hierarchical multi-functionalized NPG membrane (NPG-pTD membrane) for use in oil/water separation. The NPG-pTD membrane includes a plurality of multi-functionalized NPG nanosheets in a stacked assembly with polyphenolic nanoparticles attached to the NPG nanosheets throughout the membrane. The NPG-pTD membrane can be formed via in-situ polymerization, which is vacuum assisted, such that the phenolic compounds from the multi-functionalized NPG nanosheet form the nanoparticles. Interlayer d-spacing between the adjacent nanosheets in the stacked assembly creates expansive and constricted channels, in addition to nanochannels provided by the pores in the nanosheets, such that the membrane has aquaporin-like properties. The NPG-pTD membrane exhibits high permeability and flux and superior selectivity for effective oil/water separation.

Abstract: The present invention provides methods and devices for augmenting impaired glycocalyx barrier function in a subject in need thereof by contacting a sample (e.g., blood) obtained from the subject with a glycocalyx-mimetic adsorption media. The adsorption media includes glycosaminoglycan structures and, optionally, proteoglycan core proteins, which are conducive to enhancing and/or restoring the impaired glycocalyx barrier function in a sample. The contacted sample is subsequently separated from the adsorption media, producing a treated sample that can be infused into the subject. Methods and devices for treating a patient suffering from a disease associated with glycocalyx barrier dysfunction are also provided herein.

Abstract: An apparatus for fabricating a graphene membrane includes a first section having a first fluid chamber for housing a suspension of graphene platelets in a fluid. A second section is positionable adjacent the first section. The second section has a second fluid chamber and a porous support housed in the second fluid chamber for supporting a porous substrate. When the first section is positioned adjacent to the second section and the porous substrate is supported by the porous support, the first fluid chamber and the second fluid chamber are in fluid communication via the porous substrate. The apparatus further includes a pressurizer for creating a pressure differential between the first fluid chamber and the second fluid chamber and thereby forcing the fluid through the porous substrate and into the second fluid chamber and lodging the graphene platelets in the pores of the porous substrate.
