Reactive oxygen species (ROS) play a critical role in regulating various physiological processes. To gain a comprehensive understanding of their distinct functions in different physiological events, it is imperative to detect binary ROS simultaneously. However, the development of the sensing method capable of binary ROS detection remains a significant challenge.

The contamination of water with dyes stemming from the discharge of industrial waste poses significant environmental risks and health concerns. In this study, the phytoremediation potential of the wetland plant was investigated (as a function of plant biomass, pH, contact time, and initial dye concentration) for the removal of methylene blue and methyl red dyes from wastewater. The experimental adsorption capacities under the optimum conditions were found to be 1.

Interfacial solar vapor generation (ISVG) accompanied by photocatalytic degradation holds immense potential to mitigate water scarcity and pollution. Distinct from the two detached functional components (photothermal agent and photocatalyst) in a conventional evaporator, in this study, an all-in-one photothermal/catalytic agent, nitrogen-containing honeycomb carbon nanosheets (NHC), was engineered for synergistic high-efficiency steam generation and photocatalysis functions. It was demonstrated that the superoxide radical generated on the surface of NHC conferred its catalytic activity to the photodegradation of organic pollutants under full solar spectrum irradiation.

In this study, a novel "OFF-ON" fluorescent probe MPZ ((E)-5-((10-ethyl-2-methoxy-10H-phenothiazin-3-yl)methylene)thiazolidine-2,4-dione) based on phenothiazine is synthesized, which can rapidly (7 s) detect biogenic amines (BAs) through deprotonation, utilizing both colorimetric and fluorescent dual channels. An app for visual portable detection of fish freshness, named "Visual Evaluation", is independently developed. This app integrates several functions, including image capture, editable scanning of red, green, and blue (RGB) values, data analysis fitting, data storage, and verification.
