The field of flow chemistry has garnered considerable attention over the past 2 decades. This Perspective highlights many recent advances in the field of flow chemistry and discusses applications to the pharmaceutical industry, from discovery to manufacturing. From a synthetic perspective, a number of new enabling technologies are providing more rationale to run reactions in flow over batch techniques. Additionally, highly automated flow synthesis platforms have been developed with broad applicability across the pharmaceutical industry, ranging from advancing medicinal chemistry programs to self-optimizing synthetic routes. A combination of simplified and automated systems is discussed, demonstrating how flow chemistry solutions can be tailored to fit the specific needs of a project.

The examination of wastewater and effluents flowing into receiving water bodies is crucial for identifying pollutant sources and implementing scenarios to reduce them. In this study, QUAL2kw was used to identify, assess, and predict the pollutant load of a drainage canal located 6 km away from Anzali Wetland. Initially, the model was calibrated and validated with data collected in 2017.

Enhancing the protein content and production efficiency of is crucial as an alternative protein source. This study screened nongenetically modified yeast strains with high protein content for food ingredient production and explored the underlying mechanisms. Yeast protein levels were found to correlate with RNA, leading to a high-throughput screening method using RNA fluorescence and flow cytometry.

Achieving efficient and sustainable hydrogen production through photocatalysis is highly promising yet remains a significant challenge, especially when replacing costly noble metals with more abundant alternatives. Conversion efficiency with noble-metal-free alternatives is frequently limited by high charge recombination rates, mainly due to the sluggish transfer and inefficient consumption of photo-generated holes. To address these challenges, a rational design of noble-metal-free cocatalysts as oxidative sites is reported to facilitate hole consumption, leading to markedly increased H yield rates without relying on expensive noble metals.

Sediments are key reservoirs for rare bacterial biospheres that provide broad ecological services and resilience in riverine ecosystems. Compared with planktons, there is a lack of knowledge regarding the ecological differences between abundant and rare taxa in benthic bacteria along a large river. Here, we offer comprehensive insights into the spatiotemporal distributions, co-occurrence networks, and assembly processes of three divided categories namely always rare taxa (ART), conditionally rare taxa (CRT), and conditionally rare and abundant taxa (CRAT) in sediments covering a distance of 4,300 km in the Yangtze River.

Electricity is frequently used to produce CAPP via a variety of techniques, including plasma jets, corona discharges, dielectric barrier discharges, and glow discharges. The type and flow rates of the carrier gas(es), temperature, pressure, and vacuum can all be altered to control the desired properties of the CAPP.
