A continuous flow reactor for the efficient synthesis of nanoparticles with a high degree of crystallinity, uniform particle size, and homogenous stoichiometry throughout the crystal is described. Disclosed embodiments include a flow reactor with an energy source for rapid nucleation of the .[.procurors following.]. .Iadd.precursors to form nucleates followed .Iaddend.by a separate heating source for growing the nucleates. Segmented flow may be provided to facilitate mixing and uniform energy absorption of the precursors, and post production quality testing in communication with a control system allow automatic real-time adjustment of the production parameters. The nucleation energy source can be monomodal, multimodal, or multivariable frequency microwave energy and tuned to allow different precursors to nucleate at substantially the same time thereby resulting in a substantially homogenous nanoparticle. A shell application system may also be provided to allow one or more shell layers to be formed onto each nanoparticle.

The invention relates to a reactor system for continuous flow reactions that comprises at least two blocks (1, 2), two interlayers (8, 9) and a contact pressure device, and at least one inlet (10) and one outlet (11), wherein the first block (1), the interlayers (8, 9) and the second block (2) form a stacked arrangement fixed by the contact pressure device and, in the reactor system, at least one interlayer comprises a sealing layer (8) and one interlayer comprises channel structure element (9) comprising a reaction channel, wherein the inlet (10) is functionally connected to the inlet side of the reaction channel and the outlet (11) to the outlet side of the reaction channel, and the stacked arrangement is detachable.

Emulsion breaking and phase separation is achieved by droplet adhesion. An emulsion breaking device includes a channel having distinct adjacent zones with distinctly different surface wettability characteristics, namely, solvophilic and solvophobic surfaces. The device is positioned such that the upstream portion of the device is configured to be wetted by the continuous phase of the emulsion, and the downstream portion of the device is configured to be wetted by the dispersed phase of the emulsion. As the emulsion flows from the upstream zone to the downstream zone, the change in surface wettability characteristics promotes adhesion of the dispersed phase as the dispersed phase wets the surface of the downstream portion of the channel, which results in breaking of the emulsion. Subsequent collection of the broken emulsion in a collection vessel results in separation of the disparate phases to facilitate their recapture and recycling.

Provided are formation method and device for slug flow capable of suitably forming a stable slug flow. The formation method for slug flow includes a step of preparing a microreactor (1) that forms a fine flow passage (11), and includes a wall surface having a hydrophilic property, a hydrophilic liquid supply step of supplying the fine flow passage (11) with only a hydrophilic liquid out of the hydrophilic liquid and a hydrophobic liquid, and a step of supplying the fine flow passage (11) with the hydrophilic liquid and the hydrophobic liquid after executing the hydrophilic liquid supply step, thereby forming a slug flow in which cells formed of the hydrophilic liquid and cells formed of the hydrophobic liquid are alternately arranged in a fine-flow-passage length direction of the fine flow passage (11) in the fine flow passage (11).

The present disclosure relates to the production of platelets from megakaryocytes (Mks). In particular, the present disclosure provides systems and methods for the in vitro production of platelets from Mks using a microfluidic bioreactor having a center flow channel and uniform high-shear micrometer slits. Use of this microfluidic bioreactor enables the continuous production of millions of platelets and facilitates real-time and long-term visualization of proplatelet and platelet generation.

Different AuPd nanoparticles, ranging from sharp-branched octopods to core@shell octahedra, can be achieved by inline manipulation of reagent flowrates in a microreactor for seeded growth. Significantly, these structures represent different kinetic products, demonstrating an inline control strategy toward kinetic nanoparticle products that should be generally applicable.
