Summary: In this study, visible-light-driven heterogeneous micromotors were synthesized using a one-step hydrothermal method. These microdevices exhibit precise motion controlled by hydrogen peroxide and visible light. The velocity of the micromotors can be regulated by changing the concentration of hydrogen peroxide or the intensity of visible light. The photocatalytic propulsion of these micromotors can be conveniently switched on or off by adjusting the incident light. This approach has promising applications in environmental remediation, such as the degradation of Rhodamine B.

Summary: Growing awareness of the harmful effects of sunlight overexposure has led to the regular use of sunscreens. However, the increasing concentration of related pollutants has caused major environmental side-effects. To address this global threat, magnetically-driven photoactive microrobots have been developed for water remediation, offering an efficient solution. These microrobots exhibit magnetic steering motion and easy retrieval, thanks to their modified surface. By combining adsorption and photocatalytic activity, they can effectively degrade organic UV filters in suntan lotions. The magnetically-driven navigation contributes to the enhanced degradation of these harmful substances.

Summary: In this study, a series of crystalline Z-scheme photocatalytic heterojunctions BiOI@PCN-222 were constructed by integrating BiOI into the channel of a porphyrin-based Zr-MOF PCN-222. The resulting BP-X demonstrated stronger visible light absorption and retained the mesoporous nature. Among them, BP-3 exhibited superior adsorption and photodegradation activity towards tetracycline, attributed to its strong adsorption capacity and highly dispersed Z-scheme heterojunction.

Summary: In2S3/BiOI composites synthesized at room temperature significantly enhance the photocatalytic degradation of tetracycline hydrochloride under visible light irradiation. The heterojunctions of the composites enhance the separation ability of photogenerated carriers, with the 7-In2S3/BiOI composite achieving the best performance. The photocatalytic mechanism of In2S3/BiOI composites involving superoxide radicals and holes is proposed based on photo-electrochemical characterization and free radical tests.

Summary: Micromixers have been widely used in chemistry, biology, and medicine due to their small size, fast response time, and low reagent consumption. However, at low Reynolds numbers, the laminar flow conditions limit the fluid mixing effect, so external means are necessary to enhance mixing. In this paper, the classification and mixing principles of passive and active micromixers are reviewed, and their experiments and applications are briefly discussed. Finally, the future development trends of micromixers are summarized.
