Systems, methods, and devices for forming an array of emulsions. An exemplary device comprises a frame and at least one or a plurality of separate microfluidic modules mounted to the frame and each configured to form an array of emulsions. In some embodiments, each module may be mounted by snap-fit attachment. The device also may include the same sealing member bonded to a top side of each module and hermetically sealing each of the modules. Another exemplary microfluidic device for forming an array of emulsions comprises a stack of layers bonded together. The stack may comprise a port layer forming a plurality of ports. Each port may have a top rim formed by a protrusion that encircles the central axis of the port. The rims may be coplanar with one another to facilitate bonding of a sealing member to each rim.

A dilution device may include a first component and a second component. The first component may define a groove including an inlet portion and an outlet portion. The second component may define an inlet in fluid communication with the inlet portion of the first component and an outlet in fluid communication with the outlet portion of the first component. Relative rotation between the first component and the second component may cause relative movement between the outlet and the outlet portion that changes the effective length of the groove fluidly coupling the inlet and the outlet of the second component. The cross-sectional area of the groove may vary along a length of the groove to provide different flow characteristics depending on the effective length of the groove.

Methods for the detection of components from biological samples are provided. In certain aspects, the methods may be used to detect and/or quantify specific components in a biological sample, such as tumor cells (e.g., circulating tumor cells). Systems and devices for practicing the subject methods are also provided.

Devices, systems, and their methods of use, for generating and collecting droplets are provided. The device includes a collection region comprising a side wall canted at an angle. The invention further provides multiplex devices that increase droplet formation.

The present invention relates to a process of producing a nano-Tan IIA microemulsion system comprising the following steps: (i) preparing a dispersed phase by dissolving Tan IIA in ethanol solvent in a ratio of mass of Tan IIA:volume of ethanol solvent of 8:10; (ii) preparing a carrier by heating liquid PEG (polyethylene glycol) to 60-80° C.; (iii) adding the carrier to the dispersed phase in a mass ratio of 40:60 with further heating of the dispersed phase to 40-60° C.; (iv) elmusifying by heating until the temperature reaches 100° C., adding ACRYSOL K-140 to the mixture of the carrier and dispersed phase obtained in step (iii) in a mass ratio of 40:60 with further stirring at 500-700 rpm at about 100° C. under vacuum; and (v) filtering the product by injection through a nanofilter system before filling-packing.

A method for continuously processing at least two liquid feed streams is provided. A system for continuously processing at least two liquid feed streams is also provided.

The invention relates to a mixing system for producing a cosmetic product. The invention also relates to a capsule (7, 8) containing a cosmetic compound. The mixing system allows the production of a cosmetic product from capsules (7, 8) comprising the raw materials required for the composition of such a cosmetic product, that is the cosmetic texturising agent, the cosmetic active substance and, as required, a cosmetic perfume. The invention is applicable in the cosmetic industry.

There is described a method of formulating a customised cosmetic product, comprising the steps of: a) dispensing ingredients according to a recipe for the cosmetic product into a vessel (422) containing a mixing component (1201); b) mixing the ingredients with the mixing component to form a mixed intermediate; and c) increasing the viscosity of the intermediate to form the cosmetic product by ceasing mixing and/or adding a further ingredient. An apparatus for formulating a customised cosmetic product comprising an inventory section, a dispensing section and a vessel located in the dispensing section is also described. Furthermore, a method and apparatus for formulating a customised cosmetic product comprising selecting a cosmetic product mixer from a plurality of cosmetic product mixers based on the generation of second data based on first data indicative of a biometric measurement of a user,

An asphalt shingle coating system that includes a coater, a mixer, a viscosity gauge, a wax supply, a wax pump and a control system. The coater applies a layer of a coating asphalt mixture on an asphalt shingle substrate. The mixer mixes the coating asphalt mixture and is positioned upstream of the coater. The viscosity gauge may be positioned between the coater and the mixer, and it measures the viscosity of said coating asphalt mixture before it is delivered to the coater. The wax supply is in fluid communication with the mixer and a wax pump may deliver a volume of wax from the wax supply to the mixer, and the control system may selectively adjust the operation of the wax pump to substantially maintain a desired viscosity of said coating asphalt mixture.

The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems.
