TL;DR: In this paper, a novel hydrodynamic lift force sieving attained in an arc microchannel with a bifurcation at the downstream end is demonstrated, where fluorescent polystyrene particles with diameter of 10 or 20μm are dispersed in water or NaCl aqueous solutions so that the particles are completely neutrally buoyant, lighter or denser relative to medium.

TL;DR: In this paper, a comparison of three different micromixer types in different versions have been performed using the model system heptane/water (SDS) with regard to mean droplet size as function of total flow rate and specific energy input.

TL;DR: Two novel routes for the production of gasoline from pyrolysis oil and biogas are simulated, followed by a cradle-to-gate life-cycle assessment of the two production routes, revealing that the newly proposed processes have a clear advantage over the conventional process in some categories, particularly the global warming potential and primary energy demand.

TL;DR: In this article, a feasibility study in state-of-the-art multi-and monomode microwave cavities was conducted to outline important functionalities necessary in a microwave setup for continuous fine-chemicals synthesis.

TL;DR: In this article, the development of dedicated microfabrication technologies is summarized and recent developments of microsystems for typical application fields are shown, and specific problems of industrial application are discussed.
