A fine bubble generating nozzle may include a nozzle unit and a baffle. The nozzle unit may include: an inlet; a pressure decreasing portion configured to decrease a pressure of a gas-dissolved pressurized water introduced from the inlet; a first collision chamber disposed downstream of the pressure decreasing portion and including a first collision wall with which the gas-dissolved pressurized water introduced from the pressure decreasing portion collides so that a flow direction of the gas-dissolved pressurized water changes; a second collision chamber disposed downstream of the first collision chamber and including a second collision wall with which the gas-dissolved pressurized water having flowed through the first collision chamber collides so that the flow direction of the gas-dissolved pressurized water changes; and an outlet. The baffle may be disposed outside of the nozzle unit and is disposed at a position facing the outlet.

An aeration apparatus including a tank defining a cavity to receive a liquid, at least one aerator positioned within the tank, and a plenum connected to a bottom surface of the tank and in fluid communication with the at least one aerator, in which an air flow is directed from the plenum into the at least one aerator to deliver air to the liquid in the tank to oxidize the fluid.

A micromixer and a process of fabricating the same are disclosed which comprises a bottom housing layer having an receiving section, a mixing channel, and an output section; a top housing layer further comprising a plurality of inlet passages, and an outlet passage for obtaining the resulting mixture; the receiving section is coupled to the plurality of inlet passages, and the output section is coupled with the outlet passage; and the mixing channel further comprising a plurality of parallel zigzag channels created by a first zigzag mixing unit and a second zigzag mixing unit.

The disclosure provides for a lab-on-a-chip (LOC) device and a method of fabrication thereof. Additionally, a system and a method for point of care testing of multiple biomarkers such as glucose, cholesterol, creatinine, uric acid, and bilirubin is provided. The microfluidic assembly consists of three layers in which the top and the middle layers are made up of polydimethylsiloxane (PDMS) and the bottom layer with polyethylene terephthalate (PET). The device integrates screen printed non-enzymatic electrochemical sensors in the bottom layer for simultaneous detection of glucose, cholesterol, creatinine, uric acid, and bilirubin. A hand held potentiostat with readout enables readout for the point of care application of integrated sensing device. The device developed has potential to revamp healthcare by providing access to affordable technology for better management a diabetes and related complications at every door step.

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.

The present application discloses an exhaust gas after-treatment mixing device including a first plate, a second plate and a mixer. The mixer includes a first space, a second space and a third space located between the first space and the second space. Top portions of the first space and the second space are in communication with the third space. The mixer includes a first raised portion protruding 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 of urea evaporation is increased and the mixing uniformity is improved. Besides, a package with the exhaust gas after-treatment mixing device is also provided.
