Summary: A mass transfer model based on spatial superposition assumption is proposed to reflect the effect of heterogeneous structure on downer mass transfer behavior. This model requires fewer concentration parameters compared to the multi-scale method and is in good agreement with experimental data. The presence of clusters significantly affects gas-solid mass transfer effectiveness, deteriorating the reaction rate. The simulation shows that mass transfer near the inlet region plays a dominant role, while along the flow direction, the influence of the reaction process gradually becomes stronger.

Summary: In this study, a cluster-based mass transfer and reaction model was proposed and coupled with three-dimensional Computational Particle Fluid Dynamics (CPFD) approach to simulate the ozone decomposition in a gas-solids downer reactor. The results showed that the model considering the clustering effects predicted better ozone concentration distribution and accurately predicted the flow behaviors and reaction characteristics. The effects of operating conditions on the hydrodynamics and reaction characteristics were fully analyzed based on the accurate model predictions.

Summary: A novel rotating packed bed reactor integrated with plasma (plasma-RPB) was developed to enhance wastewater treatment by fully utilizing ozone. The ozone-water mass transfer efficiency of the plasma-RPB with different liquid distributor structures was evaluated. The plasma-RPB exhibited prominent degradation performance, with sulfamethoxazole and TOC removal efficiency reaching up to 87.6% and 82.7%, respectively, within 5 minutes.

Summary: This study found that the presence of phosphate can trigger a more efficient catalytic activation of peroxymonosulfate (PMS) at trace Co2+ dosages. The fast degradation of atrazine was observed in the Co2+/PMS/phosphate system, with phosphate promoting the production of sulfate radicals. The ligand effect on the cobalt-mediated sulfate radicals-based advanced oxidation process was investigated, with phosphate levels impacting the effectiveness of the process.

Summary: The study found that gas temperature has no significant effect on ozone concentration drop, but the appearance of electrical discharges leads to intensive ozone decomposition even at low temperatures and low powers. Ozone decomposition is mainly caused by momentary increase in gas temperature in microdischarge channels, hindering the removal of heat and affecting ozone concentration achieved.

Summary: The electrochemical fabrication of memristive devices based on Hf was demonstrated, with the impact of different phosphate buffers on conductive filament formation explored. Using 1 M phosphate buffer resulted in the formation of Hf-O-P compounds that hindered phosphate incorporation and improved the performance of anodic Hf memristors. High resolution atomic imaging provided further understanding of memristive switching in HfO2.

Summary: This review systematically evaluates and summarizes the effects of background phosphate ions on persulfate activation and contaminant degradation. Different forms of phosphate ions have different effects in different systems, and the mechanism of their influence on persulfate activation is still controversial. The presence of phosphate ions can both promote and inhibit contaminant degradation, depending on the specific reaction system.

Summary: The study used batch experiments and a numerical model to determine the optimal dosage and ratio of ozone in water treatment plants for increasing ozone absorption and utilization rates. Ozone absorption rate was minimally affected by water quality, while ozone utilization rate was closely related to water quality, with faster-consuming waters requiring equal ozone dosing in all three aeration parts for maximum utilization rate.

Summary: This study presents a semiempirical approach to model the degradation of acetaminophen by considering the rate of reactive chlorine species (RCS) production. The results show that hydraulic retention time and RCS production rate are crucial factors for ACE degradation. The developed model successfully reproduced the removal of ACE in distilled water at different concentrations. The study also assessed the degradation of ACE in actual seawater and demonstrated the positive environmental effect of the electrochemical treatment by removing both ACE and its antimicrobial activity.
