What is disclosed in the present invention is to provide a quantitative transfer pipette structure, wherein an anti-backflow compartment is configured in the first bulb. The dimensions and locations of the first bulb, the second bulb and the third bulb are specifically configured to aspirate and transfer a specific volume of the liquid to a container, mix the liquid with the substance in the container by pressing and releasing the specific bulbs, so as to achieve the effects of precise quantification and sufficient mixing.

A wet atomization apparatus includes: a process-target fluid storing container for storing the process-target fluid; a syringe including a gasket configured to be slid on an inner peripheral wall of the syringe by a plunger; a thin tube having one end inserted in the process-target fluid storing container and another end connected to the syringe; and a control section that performs control of the plunger to move forward and backward. Under the control by the control section, an atomization process is performed at least once in which the plunger is moved backward to allow the process-target fluid in the process-target fluid storing container to flow into the syringe via the thin tube so as to be stored in the syringe and the plunger is moved forward to return the process-target fluid stored in the syringe into the process-target fluid storing container via the thin tube.

Disclosed herein are systems and methods of purification of liquid from colloidal particles. More specifically, disclosed are systems and methods for treating water by effecting aggregation of colloidal particles and thus improving their sedimentation, by enhancing grouping of the particles using accelerating, decelerating, and reversing velocity gradients within the liquid. The disclosed methods and systems for water treatment allow for continuous treatment of a contaminated water stream in a single flocculation and sedimentation vessel (i.e. a hybrid process).

A device comprising, a substrate having a droplet thereover, and an electrical source coupleable to the substrate. The electrical source is configured to apply a voltage between the substrate and the droplet using an electrode. The electrode has a first portion and a second portion non-symmetric to the first portion, the first and second portions defined by a plane located normal to a longitudinal axis and through a midpoint of a length of the electrode.

A mixer gun system includes a holder cap configured to separately store components in separate chambers. The components are selectively releasable through channels fluidly communicating with the separate chambers. The components are constituent materials for a bone cement mixture. A body forms a mixing chamber and is configured to receive the holder cap. The mixing chamber includes an opening corresponding with the channels for the separate chambers. A piston is disposed within the mixing chamber. A plunger is coupled to the piston and is configured to be biased toward the mixing chamber such that when the components are released into the mixing chamber a pressure developed by a biased motion of the plunger and piston infuses the components to form bone cement. Upon resetting the plunger and the piston, the bone cement is dispensed from the mixing chamber by the same biased motion. Methods of use are disclosed.

A tattoo ink mixing apparatus has a housing having a cavity, a plunger movable between a first position and a second position, and a dynamic member disposed in the cavity and adapted to engage with the plunger distal end. The dynamic member moves in response to movement of the plunger and alternatively creates a suction force and an expulsion force in the opening of the distal end of the housing as the plunger moves between its first and second positions.

Provided in one embodiment is a method of making paste for solar cells. The method can include forcing silver through a feed tube coupled to a hydrodynamic cavitation chamber using an air-driven piston. The method can include subjecting the silver to hydrodynamic cavitation in the hydrodynamic cavitation chamber by using a hydraulic pump to pass the silver sequentially through a primary orifice, a secondary orifice, and a final orifice within the hydrodynamic cavitation chamber to produce the paste for the solar cells. The silver can include up to three unique silver powders having a total particle size distribution from 0.1 microns to 10 microns. A first silver powder can have a first average particle size of 1.5 um, a second silver powder having a second average particle size of 0.5 um, and a third silver powder having a third average particle size of 0.2 um.

Provided herein are methods for the assembly of a polynucleic acid sequence that is at least partially carried out on a microfluidic device; methods for the preparation of a library of polynucleic acid sequences; microfluidic devices; methods for designing nucleic acid sequences; methods for planning the assembly of a polynucleic acid sequence from a plurality of nucleic acid sequences; systems comprising components for carrying out these methods; computer programs which, when run on a computer, implements these methods; and computer readable medium or carrier signals encoding such a computer program.

A continuous chemical process is modified to allow parts thereto to be processed one quantum of matter at a time. This offers precision and efficiency beyond what is possible with the continuous mode. This Quantum Fluid Operation (QFO) is applied to basic unit operations: mixing, reacting, separating.
