Spin polarization induced by atomic strain of MBene promotes the ·O2 – production for groundwater disinfection
Published 2025-01-01“…An emerging approach for green disinfection lies at photocatalysis, which levers the locally generated superoxide radical (·O2 −) for neutralization. However, the spin-forbidden feature of O2 hinders the photocatalytic generation of active ·O2 −, and thus greatly limited the disinfection efficiency, especially for real groundwater with a low dissolved oxygen (DO) concentration. …”

Effects of Luteolin Treatment on Postharvest Quality and Antioxidant Capacity of Nanfeng Tangerines
Published 2024-12-01“…Furthermore, luteolin treatment inhibited malondialdehyde (MDA) and H<sub>2</sub>O<sub>2</sub> accumulation by enhancing the content of total phenols and flavonoids content, augmenting antioxidant enzyme activities (peroxidase (POD), catalase (CAT), and superoxide dismutase (SOD)), and elevating the overall antioxidant capacity measured through the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging rate. Collectively, these results demonstrate that luteolin has potential as a preservative for promoting postharvest quality and antioxidant capacity. …”

Solar Photocatalytic Degradation of Bisphenol A on Immobilized ZnO or TiO2
Published 2013-01-01“…Degradation in wastewater is slower than that in pure water up to five times, implying the scavenging behavior of effluent’s constituents against hydroxyl radicals. Finally, the presence of other endocrine disruptors, such as 17α-ethynylestradiol, spiked in the reaction mixture at low concentrations usually found in environmental samples (i.e., 100 μg/L), neither affects BPA degradation nor alters its kinetics to a considerable extent.…”
