APPARATUSES, METHODS, AND SYSTEMS FOR FABRICATING GRAPHENE MEMBRANES
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.

The methods relate to depositing one or more liquid pharmaceuticals into or onto a substrate that includes (a)(i) fibers, or (ii) both fibers and foam, and (b) activated carbon. The substrate adsorbs active pharmaceutical ingredients and absorbs a carrier liquid to facilitate safe disposal of the one or more liquid pharmaceuticals. Pharmaceutical disposal kits suitable for disposing of liquid pharmaceuticals and dissolved solid pharmaceuticals are also disclosed. The pharmaceutical disposal kits include a substrate that (1) includes (a)(i) fibers or (ii) both fibers and foam, and (b) activated carbon, and (2) is capable of adsorbing active pharmaceutical ingredients and absorbing a carrier liquid to facilitate safe disposal of the one or more liquid pharmaceuticals.
Waste disposal substrates are also disclosed. The waste disposal substrates include (a) at least one layer of fibers, (b) at least one layer containing activated carbon; and (c) at least one layer containing superabsorbent particles. Methods of using waste disposal substrates are also disclosed. Methods of using a waste disposal substrate may include contacting a waste disposal substrate with a liquid fluid, the waste disposal substrate containing: (a) at least one layer of fibers, (b) at least one layer containing activated carbon; and (c) at least one layer containing superabsorbent particles. The liquid fluid, or a component of the liquid fluid, is collected, dissolved, adsorbed, inactivated, destroyed, and/or disposed of within the waste disposal substrate.
