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.

The disclosure relates to microchemical (or microfluidic) apparatus as well as related methods for making the same. The methods generally include partial sintering of sintering powder (e.g., binderless or otherwise free-flowing sintering powder) that encloses a fugitive phase material having a shape corresponding to a desired cavity structure in the formed apparatus. Partial sintering removes the fugitive phase and produces a porous compact, which can then be machined if desired and then further fully sintered to form the final apparatus. The process can produce apparatus with small, controllable cavities shaped as desired for various microchemical or microfluidic unit operations, with a generally smooth interior cavity finish, and with materials (e.g., ceramics) able to withstand harsh environments for such unit operations.

A structure having excellent rectification performance and durability and having a micro flow channel is provided. The structure has a flow channel in the inside, wherein the cross section of the flow channel has a shape in which a region surrounded by a substantially elliptical curve and a line segment is connected to a triangular region with the base being the line segment, the region surrounded by the line segment and the substantially elliptical curve is semielliptical or more, and the base angle of the triangular region is 45 degrees or more.

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.
