“…Microreactors were built to realize difficult or unfeasible-to-control procedures of highly exothermic or fast reactions with toxic compounds for which the reaction volume has to be as low as possible. [2,3] We found that the advantages of microscale reaction technologies for biotransformation are similar to those in chemocatalysis. This is mainly the very large surface to volume ratio in, e.g., a falling-film microreactor (FFMR).…”

“…directly affecting costs and sustainability. [13][14][15][16] Enzymes are biocatalysts that can operate under mild conditions and that provide exceptionally high selectivity. These properties translate into low energy consumption, high quality products and less down-stream processing, which explains the considerable interest for their application in industrial processing.…”

This mini-review discusses some of the recent work on Novel Process Windows by the group of Micro Flow Chemistry and Process Technology at the Eindhoven University of Technology, and their associates. Novel Process Windows consist of unconventional approaches to boost chemical production, often requiring harsh reaction conditions at short to very short time-scales. These approaches are divided into six routes: the use of high temperatures, high pressures, and high concentrations (or solvent-free), new chemical transformations, explosive conditions and process simplification and integration. Microstructured reactors, due to their inherent safety, short timescales and the high degree of process control, are the means that make such extreme chemistry possible.

Pattern width homogeneity in an exposure field of gradient-index (GRIN) lens array was greatly improved by changing the sub-scan method for averaging the pattern widths. By investigating the pattern width distribution in the exposure field, it was clarified that the parts, where the printed patterns were degraded and pattern widths were notably changed, appeared as striped lines. It was supposed that the striped abnormal pattern-width change was caused by the extra exposures for the times when the sub-scan stage was stopped at both the sub-scan ends for turning the scan direction. For this reason, sub-scan length was vastly extended, and the sub-scan stage was turned at the both ends after all the patterns on a reticle passed over the actually used parts of a GRIN lens array. By this method, no patterns were exposed and projected on a wafer while the sub-scan stage was stopped for turning at the both ends. As a result, 15-µm L&S patterns were almost homogeneously printed in the exposure field within a variation range of ±6%.
