Uncovering the key factors influencing sustainable green production behavior among Chinese medicinal herb growers.

Promoting green production behavior among farmers is crucial for enhancing income, improving industrial efficiency, and ensuring ecological security. This study analyzes the determinants of green production behavior among farmers in Cheifeng, China, Using a binary logistic model on a sample of 860 microdata. The result of empirical analysis pointed out that the implementation rate of rural households was low at 54.5 %, highlighting the need for intervention. The results suggest that age, party members, total income, total area, irrigation conditions, market, policy, social factors, and knowledge transfer ability significantly influence green production behavior. Among these factors, age, party member, total area, irrigation conditions, and knowledge transfer ability have negative effects, while other factors positively affect green production. To promote green production behavior, this study recommends improving access to information, developing a training system, enhancing quality and safety information disclosure, establishing traceability mechanisms, and providing policy subsidies. This stud also highlights the need to strengthen publicity, technical guidance, and media persuasion for promoting the green production of Chinese medicinal materials.

Metal organic framework loaded fluorescent nitrogen-doped carbon nanozyme with light regulating redox ability for detection of ferric ion and glutathione.

The redox state disorder of biological system caused by oxidative stress can lead to a variety of clinical dysfunction and diseases. It is an important challenge to find artificial materials that can efficiently adjust the redox balance to maintain health. In this work, a nitrogen-doped carbon (NCDs) redox nanozyme loaded into metal organic framework (MOF, UiO-66) is designed to form NCDs/UiO-66 nanocomposites. The high specific surface area and porosity of UiO-66 serve as ideal carrier to support multifunctional NCDs. NCDs/UiO-66 nanocomposites are comprehensively investigated for their ability to scavenge or generate reactive oxygen species (ROS) and free radicals. Experimental results demonstrate that NCDs/UiO-66 can remove intrinsic free radicals (•OH, O2•- and ABTS•+), exhibiting superoxide dismutase-like activity and antioxidant capability. Moreover, NCDs/UiO-66 can efficiently produce ROS (•OH, O2•- and 1O2) under irradiation showing light induced oxidase-like activity and pro-oxidant capability. This suggests the anti-oxidant and pro-oxidant activities of NCDs/UiO-66 could be regulated easily by light irradiation. Using the fluorescent property and light-activated oxidase-like activity of NCDs/UiO-66, the methods for detection of ferric ion (Fe3+) and glutathione (GSH) are developed.
