Microfluidic conditions were applied to acid-mediated reactions, namely, glycosylation, reductive opening of the benzylidene acetal groups, and dehydration, which are the keys to the practical synthesis of N-glycans and the immunostimulating natural product, pristane. A distinctly different reactivity from that in conventional batch stirring was found; the vigorous micromixing of the reactants ...

This paper demonstrates a methodology for micromixing that is sufficiently simple that it can be used in portable microfluidic devices. It illustrates the use of the micromixer by incorporating it into an elementary, portable microfluidic system that includes sample introduction, sample filtration, and valving. This system has the following characteristics: (i) it is powered with a single hand-...

Passive micromixing can efficiently mix laminar flows through molecular and convective diffusion. Microstructures are expected to be efficient, easily integrated into micromixers, suitable for micromixers over a wide range of Re. This paper presents the enhancement effects multiscale lateral microstructures on flow field characteristics mixing efficiency numerical simulations at Re = 0.01–50. I...

The micromixing efficiency in the rotor–stator spinning disk reactor is studied for increasing injection flow rates of limiting reagent. Using both Villermaux–Dushman method and second Bourne reaction, an increase segregation index was found with rate. Mechanistic models describing micro- mesomixing were reviewed implemented to describe effects A simplified turbulent-dispersion model this trend...

Effect of hydrodynamic heterogeneity on micromixing intensification in a Taylor–Couette flow (TC) reactor with variable configurations inner cylinder has been investigated by adoption parallel competing iodide-iodate reaction system. Two types cylinder, circular and lobed (CTC LTC), were used to generate heterogeneity, focusing the effects Reynolds number, acid concentration, feeding time perfo...
