Summary: This study evaluates the integration of activated sludge process with biological Fenton reaction to enhance the treatment of antibiotics in wastewater. The research findings demonstrate that the anaerobic/aerobic sequencing batch reactor (SBR) with magnetite achieved stable and enhanced removal of sulfamethoxazole (SMX) compared to the reactor without magnetite. The presence of magnetite facilitates the generation of hydroxyl radicals (.OHs) and microbial Fe (III) reduction, resulting in improved removal efficiency of SMX and chemical oxygen demand (COD).

Summary: The production of hydroxyl radicals ((OH)-O-center dot) during composting and its effect on composting efficiency were investigated in this study. Iron mineral supplemented thermophilic composting (imTC) was proposed as a method to enhance (OH)-O-center dot production and accelerate the maturation of composting. The results showed that imTC had a 1.39-fold increase in (OH)-O-center dot production compared to ordinary thermophilic composting (oTC). The increase in (OH)-O-center dot significantly improved organic matter degradation and humic substances formation, resulting in a 25% reduction in maturity time.

Summary: This study showed that reduced oxygen mainly generates center dot OH, and photolysis products can trigger the formation of H2O2 under 254 nm UV. Additionally, evidence of direct photolysis-induced indirect photolysis phenomenon was presented, along with a comprehensive methodology to identify the presence and sources of radicals.

Summary: In this study, it was found that hydroxyl radical (center dot OH) generated from the intracellular Fenton reaction can induce significant cell death. The Fenton reaction between Fe2+ with H2O2 resulted in a shift in lipid peroxidation and cell cycle arrest. The center dot OH generated from the Fenton reaction triggered severe apoptosis but did not lead to DNA double-strand breakage.

Summary: The study compared the performance, mechanism, degradation pathways, and product toxicity of Fe(III) activated persulfate (PS) and H2O2 modified by catechin (CAT) systems in degrading atenolol (ATL) as a model contaminant. The H2O2 system showed higher degradation efficiency (91.0%) compared to the PS system (52.4%) under the same experimental condition. CAT concentration influenced ATL degradation in the H2O2 system, while the optimal CAT concentration in the PS system was 5 μM. Both systems reduced luminescent bacteria inhibition rates by approximately 25%.

Summary: This study investigated the degradation of Carbamazepine by electro-Fenton oxidation using a FeS2/carbon felt cathode, accelerating the reaction between H2O2 and ferrous ions to produce more hydroxyl radicals and eliminate iron sludge. Various operational parameters were explored, and an empirical kinetic model was established to predict changes in CBZ concentration. The contribution of different oxidation types to the EF process was calculated and the role of the FeS2-modified cathode was verified through kinetic analysis and quenching experiments.

Summary: This study demonstrates an electrochemical advanced oxidation process (EAOP) that can simultaneously catalyze the hydrogen evolution reaction (HER) and the oxygen reduction reaction (ORR) to generate atomic hydrogen (H*) and hydrogen peroxide (H2O2) in situ. By using a palladium-coated carbon-PTFE gas diffusion electrode (Pd/C GDE) as a catalytic cathode, hydroxyl radicals ((OH)-O-center dot) can be formed by the reaction of electrogenerated H* with H2O2. The H*/GDE process is more effective in degrading organic contaminants compared to the conventional H*/H2O2 process.

Summary: Sodium-ion batteries (SIBs) are promising for large-scale energy storage applications, but face challenges due to hindrance of sodium ion diffusion. Researchers have developed a three-dimensional carbon network composed of V5Se8 and multi-walled carbon nanotubes to enhance the reversible sodium ion storage capacity and cycling stability. The V5Se8/MWCNTs electrodes exhibit outstanding rate capacity, initial reversible capacity, and cyclic stability. The reaction mechanism of the electrode in SIBs has been investigated, and the full cell coupled with a Na3V2(PO4)(2-)F-3@reduced graphene oxide cathode demonstrates excellent discharge capacity and cycling stability.

Summary: We developed a tunable, ultrafast (5 seconds), and mass-producible seed-mediated synthesis method to prepare branched Au superparticles consisting of multiple small Au island-like nanoparticles by a wet chemical route. We revealed and confirmed the toggling formation mechanism of Au superparticles between the Frank-van der Merwe (FM) growth mode and the Volmer-Weber (VW) growth mode. These Au superparticles demonstrate broadband absorption from visible to near-infrared regions due to their multiple plasmonic coupling, making them suitable for applications in sensors, photothermal conversion, and therapy.
