The present invention addresses the problem of providing a method for producing microparticles. Composite microparticles are separated by mixing at least two kinds of fluids to be processed in a thin film fluid that is formed between approachable and separable opposing processing surfaces that relatively rotate, wherein the fluids to be processed are a metal fluid comprising at least two kinds of metal elements that are dissolved in a solvent in the form of metal and/or metal compound and a fluid for separation containing at least one kind of separating substance for separating a composite substance comprising the at least two kinds of metal elements. The molar ratio between the at least two kinds of metal elements contained in the resulting microparticles is controlled by controlling the circumferential speed of the rotation at a confluence where the metal fluid and the fluid for separation merge at this time.

A cavitation device and method for using the same is useful for cavitationally treating fluids by generation of hydrodynamic cavitation in the fluid followed by the subsequent collapse of cavitation bubbles. The passage of fluid through slot openings in a cylindrical insert mounted in a housing provides fluid jets in an annular cavity to induce hydrodynamic cavitation of the fluid. Fluid is discharged from the annular cavity into a downstream portion of the housing to collapse cavitation bubbles under static pressure.

The present invention discloses a system for introducing a gas into a contained media such as a pond or lake. Water is removed from the media, gas introduced, and then the water removed to the contained media.

Focused ultrasonic acoustic processing is used to prepare formulations particles ranging between approximately 10 nm and approximately 50 microns (e.g., between 1 micron and 20 microns), or between approximately 10 nm approximately 400 nm (e.g., between 10 nm and 100 nm). Formulations (e.g., nanoformulations) may include a suspension (e.g., nanosuspension), an emulsion (e.g., nanoemulsion) or another small particle system. Formulations may be used as delivery systems for therapeutic agents, e.g., a formulation may include a bioactive agent and a carrier compound such as a surfactant that encapsulates the bioactive agent.

Nozzle Assemblies and methods of use for producing a liquid jet are disclosed that may be permit adjustable time delays between mixing of fluids and observation of reactions. An example nozzle assembly includes: a housing having an inlet and an outlet and a first channel defined therebetween, where the housing includes a gas focusing aperture defining the housing outlet; an intermediate tube disposed within the first channel of the housing, where the intermediate tube has an inlet and an outlet and defines a second channel therebetween; and a central tube disposed within the second channel of the intermediate tube, where the central tube has an inlet and an outlet and defines a third channel therebetween, where the central tube outlet is longitudinally spaced apart from the intermediate tube outlet such that the intermediate tube outlet is disposed between the central tube outlet and the gas focusing aperture's inlet.

an apparatus, system, and method for contacting blood with ozone to kill microorganisms in the blood are described. The method involves injecting microbubbles of ozone containing gas into a flow of blood, preferably at a temperature of less than 12° C. The apparatus includes a blood flow conduit including a blood ozone contacting portion including a porous ozone injector. Figure to be published with the abstract:

An enzymatic processing plant for continuous flow-based enzymatic processing of organic molecules, comprises an enzymatic processing area, wherein the enzymatic processing area comprises a turbulence-generating pipe with a repeatedly changing centre-line and/or a repeatedly changing cross-section, for generating turbulence to mix a reaction mixture and prevent sedimentation of particles as the reaction mixture is flowing through the turbulence-generating pipe, and wherein the enzymatic processing plant and the enzymatic processing area are arranged such that the reaction mixture is subjected to turbulence within the enzymatic processing area for a reaction time of 15 minutes or more.

An axial impeller has blades formed from sheet metal blanks that are configured from taking a desired impeller blade and mathematically “unwinding” the blade to its flat counterpart. Preferably, the impeller blade is formed from a single rolling operation. The result of a thin, elongate blade, preferably having a trailing edge that defines a helix with rearwardly skewed, forwardly raked blades, provides an efficient impeller having good anti-ragging properties.

A stirrer is provided such that a fluid being processed can be more efficiently shown by way of the action of an intermittent jet flow and processing capacity can be improved. The stirrer concentrically includes a rotor that includes a plurality of flat vanes and that rotates, and a screen that is place around the rotor. The screen includes a plurality of slits in the circumferential direction thereof, and screen members that are positioned between adjacent slits. The fluid being processed is discharged by rotation of the rotor from the inside of the screen to the outside as an intermittent jet flow through the slits. The width of the distal working face on the distal end of the vane in the rotational direction is smaller than the width of the basal end of the vane in the rotational direction.

A bioreactor apparatus includes a vessel establishing an interior space environmentally separable from an exterior space outside of the vessel, an agitation system including mixing means arranged in the interior space and drive means adapted to rotate the mixing means. The drive means includes a drive motor that is arranged in the interior space.
