Abstract: The process for creating one or more engineered media for use in a water purification filter is a passive multi-stage multi-media filter for use in water purification. The process for creating one or more engineered media for use in a water purification filter removes harmful contaminants from a water stream including, but not limited to, toxic heavy metals and metalloids, pharmaceutical residues, micro-toxins, endocrine disrupters, chlorinated and other halogenated solvents, fluoride, nitrate, and naturally occurring radioactive contaminants. The process for creating one or more engineered media for use in a water purification filter maintains concentrations of phytochemicals that provide health benefits. Water processed through the process for creating one or more engineered media for use in a water purification filter meets United States, European Union and World Health Organization standards for safe drinking water.
Abstract: Provided is an integral 3D graphene-carbon hybrid foam composed of multiple pores and pore walls, wherein the pore walls contain single-layer or few-layer graphene sheets chemically bonded by a carbon material having a carbon material-to-graphene weight ratio from 1/100 to 1/2, wherein the few-layer graphene sheets have 2-10 layers of stacked graphene planes having an inter-plane spacing d002 from 0.3354 nm to 0.40 nm and the graphene sheets contain a pristine graphene material having essentially zero % of non-carbon elements, or a non-pristine graphene material having 0.01% to 25% by weight of non-carbon elements wherein said non-pristine graphene is selected from 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.
Abstract: A method for preparing multi-wall carbon nanotubes comprising atomizing a precursor solution comprising an aromatic hydrocarbon and a carrier gas. The mixture is then injected through an ultrasonic atomization system to form atomized precursor droplets. Then by injecting the atomized precursor droplets from the top of a vertical chemical vapor deposition reactor, the droplets can then react with a reaction gas in the reactor vessel to form a film that adsorbs to a growth surface in the reactor vessel. Layer by layer multi-wall carbon nanotubes are formed. This method is repeated to form layers of the multi-wall carbon nanotubes. The nanotubes formed have an outer diameter of 10 nm-51 nm and a length to diameter aspect ratio of 7200-13200.

Abstract: Disclosed is a catalyst for production of multi-walled carbon nanotubes, in which the catalyst includes a transition metal catalyst supported on a support mixture including MgO, and thus can increase the production of multi-walled carbon nanotubes and, at the same time, reduce the number of walls of the multi-walled carbon nanotubes to thereby reduce the surface resistance of the multi-walled carbon nanotubes. Also disclosed is a method of producing multi-walled carbon nanotubes using the catalyst. The catalyst for production of multi-walled carbon nanotubes includes: a support mixture of a first support and a second support mixed with the first support; and a transition metal catalyst supported on the support mixture.
