Summary: The application of heterogeneous catalysts in continuous-flow enantioselective hydroacylation reactions was studied. Catalysts were prepared by mixing supports and rhodium complexes, and showed excellent activity and enantioselectivity. Under optimized conditions, the catalysts exhibited high turnover numbers and could be applied to various substrates. Furthermore, sequential-flow reactions with other heterogeneous catalysts were demonstrated for the synthesis of biologically active molecules and functional materials.

Summary: A continuous-flow procedure for the synthesis of beta-ketoesters using a Sn-MCM-41 catalyst has been developed. This methodology showed good to excellent yields with a variety of aldehydes and diazoesters. The prepared beta-ketoesters were also successfully transformed into coumarin derivatives and 5-pyrazolone through sequential reactions.

Summary: A carbon nanotube-based packed-bed microreactor was developed for on-chip oxidation of silanes. The process is catalyzed by a heterogeneous gold-carbon nanotube hybrid embedded in the device with a micrometric restriction zone. Integration of the nanohybrid enables efficient flow aerobic oxidation of substrates into corresponding silanols with high selectivity and sustainable conditions.

Summary: After a century of research on heterogeneous electrocatalysis, the specific mechanisms involved, particularly in the oxygen evolution reaction on IrOx, are still not fully understood. A new proposal suggests that the reaction is driven by changes in the redox state of the Ir-O active sites rather than changes in the interfacial electric field.

Summary: This study suggests that the fine chemical and pharmaceutical sectors may soon begin to widely adopt supported transition metal catalysts, thanks to the emergence of new generation supported metal catalysts and flow chemistry. In the future, both heterogenized metal nanoparticles as well as single-site molecular and single-atom catalysts are expected to become common.

Summary: This paper presents a facile method for sorting and controlling the density of random-network sc-SWNT films. By using chemical self-assembly and click reaction, a high-purity sc-SWNT ink and chemical binding with the substrate are achieved. The resulting FETs exhibit dense and uniform SWNT films with high hole mobility, as well as good performance uniformity and resistance to exogenous disruptions.

Summary: A novel copper metal-organic framework (Cu-MOF) was constructed through self-assembled coordination under hydrothermal conditions, showing promising applications in catalysis and luminescent sensors. The Cu-MOF exhibited high catalytic efficiency in CO2 epoxidation to cyclic carbonates and could serve as a turn-on Fe3+-selective luminescent sensor. It also demonstrated excellent recycling ability and regenerability in both catalysis and sensing.

Summary: Carbon nanotubes exhibit a powerful nucleating effect on the crystallization kinetics of polyamide 66, accelerating the process significantly. Moreover, flow-induced effects, such as shear work introduced by rotational rheometry, can also influence the onset time and morphology of PA 66 crystallization.
