Apparatus for active in situ multi-element gas sparging for bioremediation or physico-chemical degration for removal of contaminants in a soil formation containing a subsurface groundwater aquifer or a substantially wet unsaturated zone, the multi-gas contained in bubbles, wherein the apparatus includes a plurality of injection wells extending to a depth of a selected aquifer; introducing an oxidizing agent comprising ozone mixed with ambient air to provide a multi-element gas by means of microporous diffusers, without applying a vacuum for extraction of stripped products or biodegration by-products, wherein said diffusers form micro-fine bubbles containing said multi-element gas that oxidizes, by stripping and decomposition, chlorinated hydrocarbons from the aquifer and surrounding saturated soil formation into harmless by-products; also including a pump for agitating water in the well selecting microbubbles, injecting them into the aquifer and effective to alter the path of micro-fine bubbles through a porous solid formation whereby enhanced contact between the oxidizing agent contained in each said bubble by stripping pollutant from solution in ambient water into the mini-atmosphere of each bubble effective to increase the efficiency and speed of remediation of a site.

A process that results in a flexible dissolvable porous solid article that can be used as a personal care composition or a fabric care composition.

A solid electrolyte structure containing a porous solid electrolyte is prepared. At least the porous solid electrolyte of the solid electrolyte structure is immersed in a first sol solution containing at least a precursor of an electrode active material as a solute. Then, the first sol solution, in which the porous solid electrolyte is immersed, is heated. A solvent of the first sol solution is evaporated by the heating, whereby a pore of the porous solid electrolyte is filled with a high concentration (a large amount) of the electrode active material precursor.

A fluid storage and dispensing system, comprising: a fluid storage and dispensing vessel constructed and arranged for selective dispensing of fluid therefrom; a solid-phase support in the vessel; and an affinity medium on the solid-phase support, wherein the affinity medium reversibly takes up the fluid when contacted therewith, and from which the fluid is disengagable under dispensing conditions. The affinity medium may be a liquid, oil, gel, or solid (porous solid, thin film solid, or bulk solid). The system of the invention may be employed for the storage and dispensing of fluids such as hydride, halide and dopant gases for manufacturing of semiconductor products.

This invention also provides a process for making amino-imines and novel amino-imines.

The invention relates to devices for performing single step assays for the determination of the presence or absence of an analyte in a liquid sample, and methods of determining the presence or absence of such analytes using such devices. Devices disclosed comprise a labeled analyte-binding reagent reversibly-immobilized on a non-porous solid material, which solid material is in physical contact with a dry porous carrier bearing an immobilized analyte-binding reagent. Also provided are quantitative assay devices.

A porous solid windscreen formed of metal, plastic or the like covers the microphone without the need for the familiar large foam ball of material over the microphone. In a disclosed embodiment, the windscreen is a monolithic structure formed by sintering the material so as to produce a relatively consistent and desired sized pore structure. The wind screen is preferably sintered while in a mold, thereby allowing it to be formed in a variety of form factors including substantially arcuate structures or non-symmetrical structures and the like to accommodate desired aesthetic and / or acoustic needs.

Disclosed is a mixer-distributor-collector apparatus for use between beds of solid particles in a fluid-solid contacting vessel. The apparatus includes a solids retaining screen, fluid deflector, passageway, fluid distributor, and flow manipulator. The flow manipulator is a device such as a honeycomb, porous solid, perforated plate, screen, or grid having an open area greater than the open area of the fluid distributor and is located below and spaced apart from the fluid distributor. The apparatus improves the fluid flow characteristics by minimizing or eliminating fluid velocity jets and / or other turbulence which can disturb the downstream particle bed. In an exemplary application, the invention finds use in simulated moving bed (SMB) adsorptive separation processes.

A method of and apparatus for continuously making an organic ester from a lower alcohol and an organic acid is disclosed. An organic acid or salt is introduced or produced in an electrode ionization (EDI) stack with a plurality of reaction chambers each formed from a porous solid ion exchange resin wafer interleaved between anion exchange membranes or an anion exchange membrane and a cation exchange membrane or an anion exchange membrane and a bipolar exchange membranes. At least some reaction chambers are esterification chambers and / or bioreactor chambers and / or chambers containing an organic acid or salt. A lower alcohol in the esterification chamber reacts with an anion to form an organic ester and water with at least some of the water splitting with the ions leaving the chamber to drive the reaction.
