A process for separation of a slurry by radially injecting a stream of a nanogas solution at a shear-focus volume within a pipe; passing an aqueous slurry through the pipe along a direction of flow and through the shear-focus volume; and shearing and/or admixing the slurry with the nanogas solution within the shear-focus volume.

The present disclosure generally provides methods of providing at least metastable radical molecular species and/or radical atomic species to a processing volume of a process chamber during an electronic device fabrication process, and apparatus related thereto. In one embodiment, the apparatus is a gas injection assembly disposed between a remote plasma source and a process chamber. The gas injection assembly includes a body, a dielectric liner disposed in the body that defines a gas mixing volume, a first flange to couple the gas injection assembly to a process chamber, and a second flange to couple the gas injection assembly to the remote plasma source. The gas injection assembly further includes one or more gas injection ports formed through the body and the liner.

Systems, apparatuses, assemblies, and methods for diesel exhaust fluid (DEF) dosing can include a body defining an injector adaptor inlet and an injector adaptor outlet; and an injector mount or interface extending from the body. The injector mount can be between the first and second ends of the injector adaptor. The injector adaptor outlet can define an area greater than an area of the injector adaptor inlet. In a side view of the injector adaptor, at a bottom side of the body, a first straight line can extend along the body from the injector adaptor inlet to the injector adaptor outlet, and at a top side of the body opposite the bottom side, a second straight line can extend along the body from the injector adaptor inlet to the injector adaptor outlet. The second straight line can be at an acute angle relative to the first straight line.

A fluid preparation system includes a tank, a chemical supply line, a mixer, and a deionized (DI) water supply line. The tank contains a first chemical solution. The chemical supply line is coupled to the tank and configured to supply the first chemical solution. The mixer is coupled to the tank. The DI water supply line is coupled to the mixer and configured to supply DI water. The first chemicals solution and the DI water are mixed at the mixer to generate a second chemical solution.

A mixer for an exhaust system of an internal combustion engine includes a mixer housing (40) with an inflow opening central axis (LE) and with an outflow opening (38). A first flow duct (48) following the inflow opening (24) in the mixer housing (40) and a second flow duct (50) lead parallel to one another to a third flow duct (54) and open into same. The third flow duct (54) leads to the outflow opening (38). The first flow duct (48) and the second flow duct (50) are provided between an outer wall (16) of the mixer housing (40) and a flow divider wall (36) enclosed by the outer wall (16), and the third flow duct (54) is enclosed by the flow divider wall (36).

A medicament preparation system includes a disposable cartridge with a flow path. Various sensors may be placed on the cartridge to measure qualities of the fluid flowing through the flow path. The sensors are placed in precise locations using various approaches that make manufacturing of the cartridge efficient and repeatable. A drain line that is susceptible to fouling may be preattached and various approaches are used to remove or reduce the fouling. An elastomeric contact can also be present in the medical preparation system and used in a conductivity measurement subsystem.

The invention relates to an apparatus for purification of biomolecules, comprising an injection device comprising an injection channel provided with at least one inlet for a precipitation agent composition and a plurality of outlets on the external surface of the injection channel and a mixing device comprising a mixing channel with at least one main inlet for a composition to be purified and at least one main outlet, and a plurality of secondary inlets, wherein the injection device and the mixing device are coupled such that each of the plurality of outlets of the injection device is connected to a respective secondary inlet of the mixing channel. The invention further relates to a set comprising the apparatus, a composition comprising at least one biomolecule and at least one impurity, and a composition comprising at least one precipitation agent, and to a method for purification of biomolecules using the apparatus.

Methods, systems, and devices, are developed for in-situ placement of a concrete mix that can have the thixotropy to hold vertical dimension without containment, while maintaining pliability to be pumped into place and manipulated to a desired shape, and can be combined with concrete set accelerators, allowing subsequent layers of this concrete mix to be continuously stacked in place to build tall walls and such without the use of forms. Concrete without these special properties is pumped toward the point of placement where it is modified by injecting and mixing, into that line of pumped concrete, an admixture containing thixotropes, thickeners and/or set accelerators or other modifiers to provide these properties and other improvements. This method allows conventional plant batching with commonly available constituent materials for batching an economical concrete that is delivered to a jobsite and then is pumped most of the way to a point of placement.

Apparatus and method for mixing reductant in an exhaust gas flow using virtual interception. Embodiments include an exhaust gas and reductant mixer comprising a body, a first flow device, and a reductant entry port. The body defines an exhaust gas flow path having a central portion. The first flow device swirls the exhaust gas in a circumferential direction with respect to the gas flow path. The reductant entry port introduces the reductant into the gas flow path at a location downstream from the first flow device and in an introduction direction (1) offset from the central portion, and (2) opposite the circumferential direction.

The present application discloses an exhaust after-treatment mixing device including a housing and a mixing assembly located within the housing. The mixing assembly includes a first space, a second space and a third space. A top portion of the first space and a top portion of the second space are both in communication with the third space. The mixing assembly is provided with a first raised portion protruding upwardly into the third space and a second raised portion located below the first raised portion. A fourth space is formed between the first raised portion and the second raised portion. As a result, the distance and time for urea evaporation are increased and the uniformity of gas flow mixing is also improved.
