Systems, devices, and methods are provided that are useful in generating a fluid suspension of nanoplasmoid bubbles. Such systems utilize a nanobubble/nanoplasmoid generator in conjunction with mechanisms for applying energy to the fluid in the form of electrolytic events, pressure waves, electrical fields, and/or magnetic fields. The nanobubble/nanoplasmoid generator is of modular construction that is readily adaptable to a wide variety of applications. Various applications of nanoplasmoid bubble suspensions so produced are described.

This in-line active and reverse calculating mass balance blending system can maintain a chemical at desired control points, such as with respect to concentration, temperature, and/or pressure, while the output flow rate is changing dynamically to a point of use. A blending unit is configured to receive and blend at least two species and deliver a mixture at selected concentrations to points of use. A controller can be configured to determine a mass balance to maintain the concentrations in the mixture using information from metrology systems and a flow in an output to the at least one point of use. The controller also can be configured to maintain a concentration in the mixture within a concentration range by controlling flow rates to the blending unit.

One or more homogenizing elements are employed in a flow through, multi-detector optical measurement system. The homogenizing elements correct for problems common to multi-detector flow-through systems such as peak tailing and non-uniform sample profile within the measurement cell. The homogenizing elements include coiled inlet tubing, a flow distributor near the inlet of the cell, and a flow distributor at the outlet of the cell. This homogenization of the sample mimics plug flow within the measurement cell and enables each detector to view the same sample composition in each individual corresponding viewed sample volume. This system is particularly beneficial when performing multiangle light scattering (MALS) measurements of narrow chromatographic peaks such as those produced by ultra-high pressure liquid chromatography (UHPLC).

A continuous acoustic chemical microreactor system is disclosed. The system includes a continuous process vessel (CPV) and an acoustic agitator coupled to the CPV and configured to agitate the CPV along an oscillation axis. The CPV includes a reactant inlet configured to receive one or more reactants into the CPV, an elongated tube coupled at a first end to the reactant inlet and configured to receive the reactants from the reactant inlet, and a product outlet coupled to a second end of the elongated tube and configured to discharge a product of a chemical reaction among the reactants from the CPV. The acoustic agitator is configured to agitate the CPV along the oscillation axis such that the inner surface of the elongated tube accelerates the one or more reactants in alternating upward and downward directions along the oscillation axis.

A mixing connector includes an intake passage, an EGR passage that fetches a portion of exhaust gas exhausted from an engine body to use as EGR gas, and that returns the EGR gas to the intake passage, and a merging section that connects the EGR passage to the intake passage so that longitudinal directions of the intake passage and the EGR passage intersect each other. An upstream side region located on an inlet port side of the intake passage from the merging section on an opposite wall surface configuring an inner surface of the intake passage and located on a side opposite to the merging section includes a first wall surface and a second wall surface which are sequentially arranged at an interval from the merging section side toward the inlet port, and a third wall surface projecting inward of the first wall surface between the first and second wall surfaces.

The present disclosure is directed towards improved systems and methods for large-scale production of nanoparticles used for delivery of therapeutic material. The apparatus can be used to manufacture a wide array of nanoparticles containing therapeutic material including, but not limited to, lipid nanoparticles and polymer nanoparticles. In certain embodiments, continuous flow operation and parallelization of microfluidic mixers contribute to increased nanoparticle production volume.

An analysis instrument may perform analytical operations on an analyte that is combined with multiple reagents prior to being introduced into a flow cell. The instrument may include a nozzle sipper that aspirates reagents from a recipient, along with an analyte. The reagents may be directed to a volume and may be repeatedly moved into and out of the volume by cycling of a pump. The reagents may be ejected into a destination recipient with the nozzle sipper promoting vorticity in the recipient to enhance mixing. The repeated aspiration and ejection through the nozzle sipper effectively mixes the reagents and the template in an automated or semi-automated fashion.
