Summary: The study investigates the degradation of norfloxacin (NOR) using the MPUV/PAA process, with higher degradation efficiency observed at pH 7 and 9, possibly due to the impact of pH on the ionic forms of NOR and the generation of reactive oxygen species (ROS). Additionally, it was found that center dot OH is primarily responsible for degradation at pH 5, while organic radicals are mainly responsible at pH 7 and 9.

Summary: The presence of polycyclic aromatic hydrocarbons (PAHs) in groundwater poses a significant threat to human health worldwide, with Fenton oxidation processes showing promising results in removing naphthalene (NaP). Among different oxidants, hydrogen peroxide (H2O2) proved to be the most effective in degrading NaP. Additionally, the inhibitory effects of weak alkaline pH and HCO3- in actual groundwater can be counteracted by increasing dosages of oxidants and Fe(II).

Summary: Reactive oxygen species (ROS) act as secondary messengers that activate signal transduction and alter gene expression. The chemical identity and subcellular origin of ROS determine the transcriptome response. Transcriptomic studies on altered ROS metabolism in plant peroxisomes reveal common transcriptional footprints involved in metabolic pathways, gene regulation, and plant responses to abiotic stresses. Human orthologs of peroxisomal-dependent proteins are associated with cancer pathologies. Peroxisomal footprints provide valuable insights into peroxisomal functions in cellular metabolism under normal and stress conditions.

Summary: This study investigates the decomposition of H2O2 over six different iron minerals and finds hematite and goethite to be the most promising minerals for environmental cleanup due to their high ROS production. Magnetite and maghemite are highly active for both H2O2 decomposition and O-2 production at neutral and basic pHs. Ferrihydrite and feroxyhyte, on the other hand, are problematic minerals for CHP as they have high O-2 production and negligible ROS generation at all pHs.

Summary: In this study, a nanozyme-loaded hydrogel, Fe3O4-CaO2-Hydrogel, was modified and analyzed as a root canal disinfectant material. The results showed that Fe3O4-CaO2-Hydrogel exhibited excellent release profile, biocompatibility, and antibacterial activity against E. faecalis and S. sanguis biofilms. It also effectively eliminated the root canal bacterial biofilm and prevented inflammation expansion in vivo.

Summary: This study reveals the significant influence of the C/Fe molar ratio on the production of hydrogen peroxide and hydroxyl radical during the oxygenation of reduced iron and natural organic matter in the subsurface. The accumulation of hydroxyl radical increases more prominently with the increase in the C/Fe ratio.

Summary: This study presents a synergistic strategy to enhance the efficiency of Cu-Fenton reactions at near-neutral pH by introducing MoO3 cocatalyst and creatinine assistant. The introduced CuCr2/MoO3 cocatalytic system exhibits excellent activity, facilitating the rate-limiting step of Cu-Fenton reactions and enabling efficient decomposition of H2O2 for ROS generation. This system shows great potential in Cu2+ detection, ROS-based chemodynamic therapy, and sterilization.

Summary: UV/chlorine showed higher BPA degradation efficiency and pH-dependency than UV/H2O2 due to chlorination and the synergy of center dot OH and RCS. The primary radicals, center dot OH and Cl center dot, played a pivotal role in BPA degradation in UV/chlorine process at all pH investigated. Chlorination, hydroxylation, and breakage of the isopropylidene chain were the decomposition pathways in the UV/chlorine system, while only hydroxylation and breakage of the isopropylidene chain occurred in the UV/H2O2 system. Toxicity analysis revealed that the UV/chlorine system produced a mixture with higher toxicity compared to the UV/H2O2 system. Careful consideration of the possible environmental risk is required when using UV/chlorine to remove BPA in real waters.
