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.

A solid fiber is described, where the solid fiber is characterized by (a) a modification degree Do/Di, in a cross section of the solid fiber of 1.20 to 8.50 where the inscribed circle diameter is denoted by Di and the circumscribed circle diameter is denoted by Do; and (b) a porous specific surface area of not less than 30 m.sup.2/g.

A chromatograph is provided for identifying components of a mixture. Components are identified by different rates of adsorption and/or desorption with a material phase. In one embodiment, an electrical lead is connected to the material phase for supplying an electrical charge to the material phase. The electrical charge alters the rate of adsorption/desorption of the components with the material phase. In another embodiment, the material phase is disposed between two conductors with electrical leads connected to each of the conductors. A charge differential between the two conductors alters the rate of adsorption and/or desorption of components with the material phase.

Provided are a water-absorbing resin having more excellent balance of fluid retention capacity, liquid permeability, and low dustiness and a novel measurement method which enables evaluation of excellent physical properties of the water-absorbing resin. A method for measuring an absorption speed of a particulate water-absorbing agent is a method including the step of applying pressure to a portion of a bottom surface of a measurement container (51) by use of a flat plate (52) in a state in which part or whole of the particulate water-absorbing agent (56) is fixed on the bottom surface of the measurement container (51), the bottom surface being surrounded by a frame, introducing an aqueous solution through a liquid injection inlet (54) with which the flat plate (52) is equipped, and then measuring the amount of time elapsed until an end of absorption of the introduced aqueous solution by the particulate water-absorbing agent (56).

Provided herein are methods, systems, and devices incorporating use of materials to store, ship, and deliver process gases to micro-electronics fabrication processes and other critical process applications.

An embodiment of the present invention relates to a secondary battery, and a technical issue to address is to provide a secondary battery having excellent stability. To this end, disclosed is a secondary battery, comprising: an electrode assembly; a can which accommodates the electrode assembly and an electrolyte, and has a beading part formed above the electrode assembly; a cap assembly for sealing the can; and an adsorption member which is disposed in a space including at least a gap between the electrode assembly and the beading part, and which reacts with the electrolyte after a specific time period lapses after coming into contact with the electrolyte, thereby adsorbing the electrolyte.

A superabsorbent polymer that may continuously and safely exhibit improved bacterial growth inhibition property and deodorization property, without deterioration of the properties of superabsorbent polymer such as centrifuge retention capacity and absorption under pressure, and the like, and a method for preparing the same are provided.

A sintered elastomeric material combined with at least one absorbent material and formed into a thin compressible sheet. The material finds particular use in venting or filtering gasses. In specific examples, the elastomeric material may be a thermoplastic elastomer and the absorbent material may be carbon. When an amount of carbon (or any other type of conductive material) included with the elastomeric material is high enough, the material may also find use as a conductive material.

A composition for treating water including an organic soil amendment and having ions bound thereto is beneficial to aid in the removal of aqueous contaminants, such as phosphate, other phosphorus containing compounds, arsenic, arsenic containing compounds, fluorides, and PFAS from water. In these compositions the ions include rare earth cations, iron cations, and mixtures thereof. There are also methods for making these soil amendment compositions, as well as methods for using these compositions to effectively remove contaminants from water.

The present invention relates to a method and apparatus for providing and/or receiving audible sound. In particular, the invention relates to apparatus, such as a micro speaker, which includes an active region which comprises an adsorbent element in the form of a self-supporting monolith-like element with a porous reticulated structure. The adsorbent element includes adsorbent material which comprises microporous organic polymer (MOP) material. The apparatus of the present invention is suitable for use in an electronic device, for example a mobile or portable electronic device, to provide improved audible sound.
