摘要： A method includes mixing a first deionized water (DI) water from a first pipe and a second DI water from a second pipe in a merging pipe that is in fluid communication with the first pipe and the second pipe. An electrical resistivity of the first DI water is different from an electrical resistivity of the second DI water. A mixture of the first DI water and the second DI water is applied from the merging pipe onto a wafer.

摘要： A fluidic centripetal apparatus for testing components of a biological material in a fluid is presented. The fluidic centripetal device is adapted to be received within a rotatable holder. The apparatus comprises a fluidic component layer having fluidic features on at least a front face and a bottom component layer bonded to a rear of the fluidic component layer thereby creating a fluidic network through which the fluid flows under centripetal force. In one embodiment, the fluidic feature may be a bottom-Tillable chamber coupled to an entry channel for receiving the fluid, the chamber inlet being provided at an outer side of the bottom-fillable chamber. In another embodiment, the fluidic feature may be a retention chamber coupled to an entry channel for receiving the fluid, a container wholly provided in the retention chamber and containing a liquid diluent, the container maintaining the liquid diluent in the container until it releases it in the retention chamber upon application of an external force to the container, thereby restoring the fluidic connection between the liquid diluent and the fluid in the retention chamber. Additionally, the retention chamber can have a flow decoupling receptacle for receiving the fluid, located at the outer side of the retention chamber and interrupting a fluidic connection between the entry and exit of the retention chamber. A test apparatus and a testing method using a fluidic centripetal device for testing components of a biological material in a fluid are also provided.

摘要： The present invention is directed towards a rotary compression mixer for providing the user with a rotary compression mixer wherein the user can directly manipulate the resultant electrical charge imbalances or coherence domains of a liquid. The motor of the rotary compression mixer recirculates liquids and gases within the liquid container, while simultaneously compressing the liquid while moving the gases and liquids centrifugally outward towards the liquid container.

摘要： A system for mixing fire-suppressant gel with water on board an aircraft includes a gel reservoir mounted in the aircraft, a pump for injecting gel into a flow of water into an aircraft-mounted payload tank, and a control system for controlling gel-water mix ratios. The control system monitors water volume flowing into the water tank, and regulates the gel pump to inject gel in appropriate amounts to produce gel-water emulsions having precise gel-water ratios. Settings for the control system are set by the pilot before water flow water is initiated. Once the aircraft is in flight, the gel-water mixing process is automatically controlled through a trigger on the pilot's control stick. The aircraft may be a helicopter or fixed-wing aircraft adapted to load water from a lake or other source while in flight, or a fixed-wing aircraft adapted to load water on land from a pressurized water source.

摘要： The present invention generally relates to emulsions, and more particularly, to multiple emulsions. In one aspect, multiple emulsions are formed by urging a fluid into a channel, e.g., by causing the fluid to enter the channel as a “jet.” Side channels can be used to encapsulate the fluid with a surrounding fluid. In some cases, multiple fluids may flow through a channel collinearly before multiple emulsion droplets are formed. The fluidic channels may also, in certain embodiments, include varying degrees of hydrophilicity or hydrophobicity. As examples, the fluidic channel may be relatively hydrophilic upstream of an intersection (or other region within the channel) and relatively hydrophobic downstream of the intersection, or vice versa. In some cases, the average cross-sectional dimension may change, e.g., at an intersection. For instance, the average cross-sectional dimension may increase at the intersection. Surprisingly, a relatively small increase in dimension, in combination with a change in hydrophilicity of the fluidic channel, may delay droplet formation of a stream of collinearly-flowing multiple fluids under certain flow conditions; accordingly, the point at which multiple emulsion droplets are formed can be readily controlled within the fluidic channel. In some cases, the multiple droplet may be formed from the collinear flow of fluids at (or near) a single location within the fluidic channel. In addition, unexpectedly, systems such as those described herein may be used to encapsulate fluids in single or multiple emulsions that are difficult or impossible to encapsulate using other techniques, such as fluids with low surface tension, viscous fluids, or viscoelastic fluids. Other aspects of the invention are generally directed to methods of making and using such systems, kits involving such systems, emulsions created using such systems, or the like.

摘要： Methods and devices for forming droplets are provided. In certain embodiments, the methods and devices form droplets having different diameters. In particular embodiments, the device includes a fluid supply channel, a collection chamber, and one or more nozzles disposed between the fluid supply channel and the collection chamber. Each nozzle may include an inlet portion with a channel height, a first step with a first step height and a first tread length, and a second step with a second step height and a second tread length. In certain embodiments, the first step height is greater than the channel height, and the second step height is greater than the first step height.

摘要： The present invention relates to a pickering emulsion composition using polyimide particles and a method for preparing the same. The pickering emulsion stabilized by the polyimide particles according to the present invention has a very stable dispersed phase and does not cause flocculation, creaming, coalescence and phase separation even after a long time, and has an advantage of being capable of forming both an oil-in-water type emulsion and a water-in-oil type emulsion. Further, the polyimide particles used in the present invention can be synthesized in a simple manner and have partial wettability without the surface treatment and pH control so that they can be easily used for the emulsion stabilization.
