A filter apparatus for removing small molecule chemotherapy agents from blood is provided. The filter apparatus comprises a housing with an extraction media comprised of polymer coated carbon cores. Also provided are methods of treating a subject with cancer of an organ or region comprising administering a chemotherapeutic agent to the organ or region, collecting blood laded with chemotherapeutic agent from the isolated organ, filtering the blood laden with chemotherapeutic agent to reduce the chemotherapeutic agent in the blood and returning the blood to the subject.

Presented herein is a new concept of uniformly spin coating a flat surface with a stationary phase and creating a gas chromatography column by pressing a grooved lid, with micro-stamped ridges, down onto the coated substrate. The lids are molded out of commercially available rigid materials including epoxies so that when pressed onto a flat surface it will create an air tight seal. The epoxy material is rendered inert by a thin layer of gold.

A first process and sorbent for removing ammonia from a gaseous environment, the sorbent comprised of graphene oxide having supported thereon at least one compound selected from metal salts, metal oxides and acids, each of which is capable of adsorbing ammonia. A second process and sorbent system for removing ammonia and a volatile organic compound from a gaseous environment; the sorbent system comprised of two graphene-based materials: (a) the aforementioned graphene oxide, and (b) a nitrogen and oxygen-functionalized graphene. The sorbents are regenerable under a pressure gradient with little or no application of heat. The processes are operable through multiple adsorption-desorption cycles and are applicable to purifying and revitalizing air contaminated with ammonia and organic compounds as may be found in spacesuits, aerospace cabins, underwater vehicles, and other confined-entry environments.

A method of treating wood chips to be used as a media for ameliorating oil spills on land or water involves heating in a mixture of petroleum wax and vegetable oil to remove moisture content and open the pores of the wood chip to allow the oil/wax blend to penetrate into the interior of the wood chips and subsequently grinding up the chips to a predetermined mesh size. The ground chips impregnated with wax/oil are then blended with magnetic iron ore concentrate and packaged/bagged for later distribution on an oil slick. The magnetic iron ore concentrate clings to the ground, oil/wax coated wood chips and facilitates retrieving the ground chips that have absorbed the spilled oil using a magnetic pick-up.

An adsorbent for a target compound can include porous carbon particles having pores with a predominant pore size less than 10 nm, and magnetic nanoparticles (MNP) nucleated on the carbon surface and within the pores of carbon particles to provide a carbon magnetic nanoparticle adsorbent (C-MNA). A method for removing target compounds with an adsorbent, a system for removing contaminants from a liquid, and a method for adsorbing target compounds from a fluid are also disclosed.

Air filter media comprising at least one active bead layer comprises an antistatic agent and polyethylenimine coated polymeric beads that can provide better formaldehyde abatement properties than incumbent activated carbon filters and can be prepared by using existing processing facilities for manufacture of incumbent activated carbon filters.

A gas chromatography device for peak focusing of one or more target analytes is provided that include a chromatographic column with an inlet and an outlet. A stationary phase is deposited inside the chromatographic column and has a positive thickness gradient. The stationary phase extends from the inlet to the outlet and has a first thickness at the inlet of the chromatographic column and a second thickness at the outlet of the chromatographic column. The second thickness is at least about 10% greater than the first thickness. Methods of peak focusing in a gas chromatography device, method of verifying peak focusing in a gas chromatography device and creating a gas chromatography device having a chromatographic column with a positive thickness gradient are also provided.

To provide a PTP blister sheet exhibiting a high adsorption effect over prolonged periods, and a PTP blister pack formed from it. A PTP blister sheet having at least a gas barrier layer and an odor adsorption layer, wherein the odor adsorption layer comprises a heat-sealable resin containing an odor adsorption agent, and the odor adsorption agent is formed by a chemical adsorption agent supported on an inorganic porous body, and a PTP blister pack formed from it.

Method and systems are disclosed for selectively removing naturally-occurring sugars in beverages in an effective, affordable and scalable manner.
