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.

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.

The present disclosure relates to a process for the preparation of polyethylene by polymerizing in a slurry ethylene and optionally one or more C.sub.3 to C.sub.10 alpha-olefins. In some embodiments, the polymerization is carried out in a cylindrical polymerization reactor equipped with an agitator for mixing the contents of the reactor and inducing a flow of the slurry, the ethylene is fed into the reactor by an ethylene injection system comprising one or more injection nozzles which project through the bottom reactor head or through the reactor wall and extend from 0.02-0.5 times the inner diameter D into the reactor, and the ethylene exits the injection nozzle with an exit velocity from 10-200 m/s.

Techniques or processes for efficiently producing concrete using dynamic feedback are disclosed. A concrete plant can use a control system to manage concrete production based on the dynamic feedback. The dynamic feedback can control mixing of concrete ingredients so as to yield uniform particle distribution for the concrete ingredients. The dynamic feedback can also avoid overflow situations as well as yield improved loading of the resulting concrete into a concrete transport vehicle (e.g., concrete truck).

Embodiments of the present application relate to compositions bupivacaine multivesicular liposomes (MVLs) prepared by a commercial manufacturing process with large particle diameter span.

A method is provided for monitoring a flow behavior of mixed components without requiring additional instrumentation or sampling. The method is carried out by determining ratios of the power required to rotate a mixing impeller at different rotational speeds and then comparing the ratios. Characteristics about the mixed components are determined based on differences between the ratios.

The invention provides the following advantages: the present invention provides a quantum dot polarizer and manufacturing method thereof. The quantum dot polarizer comprises a first protective layer and a second protective layer, and the first protective layer or the second protective layer being a complex film comprising quantum dots. As such, without increasing the thickness of display, the invention can improve color spectrum and transmittance, and is applicable to ultra-thin display devices at low cost. The manufacturing method adds the quantum dots to the cotton glue for forming protective layers by extension or coating process to obtain quantum dot protective layer used for quantum dot polarizer. As such, the invention can avoid humidity and oxygen affecting the quantum dots and reduce cost by eliminating manufacturing independent quantum dot element separately.

Embodiments of the present application relate to commercial manufacturing processes for making bupivacaine multivesicular liposomes (MVLs) using independently operating dual tangential flow filtration modules.

Apparatus that mixes non-homogenous fluid. A threaded shaft within a housing circulates fluid within a container to effect mixing. In one embodiment, when placed in a container of fluid, the housing the fluid is recirculated through opposing ends of the housing. In an embodiment of a related method for mixing, a pump housing containing a screw journaled for rotation receives fluid within a container and conveys the fluid therethrough to circulate a fluid portion in the container along an exterior surface of the housing for mixing with another fluid portion to improve fluid homogeneity. After mixing, the portion of the fluid which first circulates through the housing may recirculate through the housing with said another portion of the fluid. The fluid may be continuously mixed and recirculated through the housing.
