A microfluidic system and method suitable for liquid mixing. The microfluidic system uses a pump (400) as the driving source, which draws at least two liquid samples that are to be mixed into the pump (400). Some air is drawn into the pump (400) as well. The system is also comprised of a mixing reservoir (203). The two liquids drawn into the pump (400) are pushed into the mixing reservoir (203). The air bubbles generated by the air have a stirring effect on the mixed liquid in the mixing reservoir (203). After the air bubbles burst, left at rest, and the air has risen to the top of the mixing reservoir (203), the mixed liquid is drawn back to the pump (400) and fed to the outlet (103) for subsequent detection steps. The addition of an antifoaming agent will prevent the accumulation of air bubbles during the mixing process. In the system, the valves (501, 502, 503, 504) and the sensors (601, 602, 603, 604) in the microfluidic channels (301, 302, 303, 304) will be used for the operation of the microfluidic system and for the precise control of the flow.

A mixing device serves for producing a powder mixture of a first powder component and at least one second powder component for an additive manufacturing device. The mixing device includes a first container for receiving the first and/or the second powder component, where a discharge opening for discharging the first and/or the second powder component is provided at a lower boundary of the first container, and a second container for receiving the first and/or the second powder component. The second container is designed to be at least partially open towards an upper side. The first and second container each include at least one fluidization zone for introducing a gas into the first and second container. The mixing device further includes a powder conduit that connects to the discharge opening of the first container and is guided into the second container.

An injection mixer is provided, which includes an injection module, a valve seat module, and an adjusting module. The injection module may be disposed to penetrate one end of a bucket container. The valve seat module may be disposed at the end of the injection module, and the valve seat module may be disposed with at least one fluid supply channel and at least one outlet channel. The adjusting module may be disposed at the valve seat module to penetrate therethrough. The adjusting module may be movably connected to the injection module. When the adjusting module is driven to move the injection module towards or away from the valve seat module, an annular protrusion may approach or move away from the inner wall of the bucket container, and a size of the predetermined gap may be reduced or increased.

A method and a device for air injection into a vinification tank (1) use air injection nozzles (2) installed therein. A rule is applied for automatic variation of injections with time, by a coordinated and combined action of the nozzles, so that for each of the installed nozzles the delivered air jets may be modulated in duration and frequency and combined with the jets delivered by the other nozzles according to a programmable sequence.

Disclosed is a device for contactlessly mixing fluid present on the upper surface of the slide, where the device comprises a first nozzle array and a second nozzle array, the first nozzle array adapted to impart a bulk fluid flow to the fluid present on the upper surface of the slide, and the second nozzle array adapted to impart at least a first regional fluid flow to at least a portion of the fluid present on the upper surface of the slide

A microsphere cavity that forms a whispering gallery mode is used. By vibrationally coupling a whispering gallery mode being one of kinds of an optical mode to a vibrational mode of water or a liquid other than water, ultra strong coupling water or a liquid in a vibrational coupling state is generated. A first example is to acquire aerosol in which water itself or a liquid itself other than water constitutes a micro-water sphere cavity or a micro-liquid sphere cavity (50) and is a dispersoid. A second example is to acquire colloid or emulsion in which a micro-dielectric sphere cavity (53) is a dispersoid and water or a liquid other than water is a dispersion medium.

A bubble generation device intermittently generates large bubbles in a liquid phase. The bubble generation device includes a bubble storing container, a pivot, and a pair of edge portion receivers. The bubble storing container stores bubbles generated by a gas supply nozzle in the liquid. The pivot allows the bubble storing container to pivot thereon, thereby releasing the large bubbles from the bubble storing container. The pair of edge portion receivers receives and blocks an edge portion of the bubble storing container to limit pivot of the bubble storing container. An inside of the bubble storing container is partitioned by a partition that is installed in an axial direction of the pivot.
