Summary: This study synthesized a magnetic heterojunction Cu2O/CoFe2O4 (CC) catalyst for Peroxymonosulfate (PMS) activation and proposed an innovative reaction mechanism based on electron migration from Cu2O to CoFe2O4 and the magnetic moment of CC. The CC/PMS system demonstrated efficient removal of antibiotic tetracycline (TC), with 98.0% removal after 30 minutes. The catalytic activity of CC/PMS was higher than that of Cu2O/PMS and CoFe2O4/PMS, and was pH-insensitive. Additionally, coexisting inorganic ions and humic acid did not inhibit TC removal, and the CC/PMS system exhibited excellent reusability.

Summary: This paper addresses the classification problem of permutation matrices and the importance of permutation similarity relations in investigating symmetric matrix equations. Three problems are solved: the canonical form of a permutation similarity class, the standard form of arbitrary permutation matrix, and finding the permutation matrix T such that T(-1 )AT is in canonical form for any permutation matrix A. The paper also demonstrates the decomposition theorem of permutation matrices and the factorization theorem of both permutation matrices and monomial matrices.

Summary: Previous studies focused on direct interactions of plastics with microorganisms, but ignored their ecotoxicity effects on the dissemination of antibiotic resistance genes (ARGs). This study reveals that environmentally relevant concentrations of phthalates (PAEs) significantly enhance the transfer of ARGs among environmental microorganisms. The interaction between PAEs and cell membrane phospholipids lowers membrane fluidity and increases permeability, facilitating gene transfer. Increased levels of reactive oxygen species and overexpression of conjugation-associated genes under PAE stress also contribute to enhanced gene transfer. This study provides important insights into the environmental risks of plastics and the control of ARG spreading.

Summary: In this study, a g-C3N4 supported NiCx nanoclusters catalyst (NiCx-CN) was developed and its capability in activating peroxymonosulfate (PMS) was investigated. The mechanism investigation revealed that singlet oxygen (1O2) formed during the catalytic process had limited contribution to BPA elimination. Interestingly, high-valent nickel-oxo species (Ni&+=O) generated after the interaction of NiCx-CN and PMS were identified as the dominant reactive oxygen species (ROS). The prepared NiCx-CN also exhibited excellent resistance to interference from inorganic anions. Three BPA degradation routes were proposed based on the transformation intermediates. This study provides a new approach for the efficient degradation of organic pollutants using heterogeneous Ni-based catalysts through PMS activation via a nonradical mechanism.

Summary: Clarifying the reaction pathways at the solid-water interface and in bulk water solution is crucial for designing heterogeneous catalysts for selective oxidation of organic pollutants. In this study, the origin of organic oxidation reactions with metal oxide catalysts is unraveled, showing that radical-based advanced oxidation processes prevail in bulk water but not on solid catalyst surfaces. These findings provide a fundamental understanding of catalytic organic oxidation processes at the solid-water interface and can guide the design of heterogeneous nanocatalysts.

Summary: This study investigates the dynamics of nitrogen removal and antibiotic resistance genes (ARGs) between Shortcut nitrification-denitrification (SCND) and full nitrification-denitrification (FND) processes under long-term selective pressure conditions. The results show that the SCND process exhibits higher extracellular polymers, respiratory activity, TN removal performance, and impact resistance compared to the FND process. Furthermore, the SCND process maintains a lower abundance of total ARGs and shows better inhibition effect on potential pathogenic bacteria proliferation.

Summary: In this study, it was found that natural polyphenols can assist in the activation of peracetic acid by conveniently obtained Fe(III), leading to efficient removal of bisphenol A. Hydroxyl radicals (center dot OH) are the main contributors to BPA degradation, with superoxide radicals (O2 center dot-) functioning as intermediates. The reaction intermediates between polyphenols and reactive oxygen species play a crucial role in the regeneration of Fe(II) and enhanced activation of peracetic acid.
