A novel electrowetting-on-dielectrics (EWOD) device in open planar geometry allows probing of droplet mixing on a superhydrophobic substrate under quasi contact-free conditions. We demonstrate a droplet-based microreactor with integrated convective-flow mixing for the reactive-mixing of CaCl(2)/Na(2)CO(3) solutions. The device provides unique conditions for scattering, spectroscopy and imaging ...

Density gradient ultracentrifuge separation has been employed as a process-analysis microsystem combining a microreactor and a separator. As a paradigm, intermediates formed after tens of seconds in the galvanic replacement of Ag nanoplates in high concentrated AuCl(4)(-) solution are captured, providing evidence of the mechanism of the reaction, which is difficult to obtain in other ways.

In this study, an efficient and green process for the synthesis of dihydropyrimidin-2(1H)-ones from aromatic benzaldehydes, ethyl acetoacetate and urea using Al-MCM-41 as heterogeneous catalyst and microreactor under solvent-free conditions has been developed. The advantages of this method are easy work-up procedure, regeneration of the catalyst, clean and neutral reaction conditions.

The single particle hydrogenation of methylene blue over a Pd/SiO2 catalyst was monitored in droplet-microreactor, using red/green/blue optical microscopy.

Hypervalent iodine(III)/TEMPO-mediated oxidation of various aliphatic, aromatic and allylic alcohols to their corresponding carbonyl compounds was successfully achieved by using microreactor technology. This method can be used as an alternative for the oxidation of various alcohols achieving excellent yields and selectivities in significantly shortened reaction times.

We found that an integrated flow microreactor system enables the preparation of boronic esters bearing electrophilic functional groups using organolithium chemistry and that it allows for their use in Suzuki-Miyaura cross-coupling without intentionally added base. Based on this method, cross-coupling of two aryl halides bearing electrophilic functional groups was accomplished to obtain the corr...

Microreactor technology and flow chemistry could play an important role in the development of green and sustainable synthetic processes. In this review, some recent relevant examples in the field of flash chemistry, catalysis, hazardous chemistry and continuous flow processing are described. Selected examples highlight the role that flow chemistry could play in the near future for a sustainable...

Silver microflower arrays constructed by upright nanoplates and attached nanoparticles were fabricated inside a microfluidic channel, thus a robust catalytic microreactor for allowing in situ SERS monitoring was proposed. On-chip catalytic reduction shows that the silver microflowers have high catalytic activity and SERS enhancement.
