Post-synthesis surface modification of Cu/Zr metal azolate framework: A pathway to highly sensitive electrochemical biosensors for atrazine detection.

Anal Chim Acta

Dept. of Electronic Materials Engineering, Kwangwoon University, Seoul, 01897, Republic of Korea. Electronic address:

Background: Atrazine (ATZ), a pesticide that poses serious health problems, is observed in the environment, thereby prompting its periodic monitoring and control using functional biosensors. However, established methods for ATZ detection have limited applicability. Two-dimensional (2D) metal azolate frameworks (MAF) have a higher surface area per unit volume and provide easier access to active sites.

Given the growing concern over the impact of brain health in individuals with overweight, understanding how mental exertion (ME) during exercise affects substrate oxidation and cardiorespiratory outcomes is crucial. This study examines how ME impacts these outcomes during an incremental exercise test in adults with overweight. Seventeen adults who were overweight completed an incremental exercise test on a cycle ergometer two times, with and without the Stroop task.

College of Animal Science and Technology, Northwest A&F University, 22 Xinong Road, Yangling, Shaanxi 712100, China. Electronic address:

Heat-induced stress has a significant impact on the health of broilers. It induces panting behavior and elevates oxygen consumption, leading to considerable strain on the broiler lungs. However, the precise effects of heat stress on lung injury, along with changes in the lung and gut microbiota, are not yet fully understood.

Anion vacancy engineered Cu/ZnInS-V/TiO-V S-scheme heterojunction for enhancing photocatalytic overall water splitting.

J Colloid Interface Sci

January 2025

National Center for International Research on Photoelectric and Energy Materials, Yunnan Key Laboratory for Micro/Nano Materials & Technology, School of Materials and Energy, Yunnan University, Kunming 650091 China; Southwest United Graduate School, Kunming 650091 China. Electronic address:

Heterojunction materials for photocatalytic overall water splitting (POWS) become popular in recent times. However, even in the superior S-scheme heterojunction, the two semiconductor materials still do not have an efficient activity to separate and migrate photogenerated carriers. To further improve the charge separation and enhance the activity of POWS, a novel S-scheme heterojunction photocatalyst, Cu/ZnInS-V/TiO-V, was synthesized using solvothermal and calcination methods.
