TL;DR: In this article, the effects of the capillary length (0.4-2.2 m), flow rate ( 0.1-12 mL/min), and aqueous-to-organic volumetric flow ratio (0.,25-9) on the slug, bubbly, parallel, and annular flow hydrodynamics were investigated.

TL;DR: In this paper, the direct synthesis of NOx from N2 and O2 by non-thermal plasma at an atmospheric pressure and low temperature is presented, which is considered to be an attractive option for replacement of the Haber-Bosch process.

TL;DR: In this article, a method and a micromixer for mixing at least two liquids is described, which is characterized by the following steps: a plurality of separated liquid currents of both liquids are brought together and alternately adjacent liquid lamellae of both liquid streams are formed; the combined liquid currents are carried away and a focussed total liquid current is formed.

TL;DR: A selection of five-membered hetero-aromatics were successfully trifluoromethylated and perfluoroalkylated within several minutes (8-20 min) and the application of microflow technology could greatly enhance and intensify these reactions.

TL;DR: In this article, successful applications of the chemical microprocess technology in the field of screening and the synthesis of fine chemicals using also new preparation routes are presented, which allows new screening methods for the preparation of compound libraries or the investigation of catalysts, and offers novel possibilities for the production of chemicals on an industrial scale.
