Summary: The efficient and cost-effective removal of polycyclic aromatic hydrocarbons (PAHs) can be achieved through combined cavitation and oxidation processes. Various methods such as sonochemistry, biodegradation, photodegradation, Fenton oxidation, ozone oxidation, and photochemical oxidation have been reviewed for PAH removal. Factors controlling cavitation under sonochemical irradiation, the performance of different reactors, and the influence of gas sources on degradation efficiency have been discussed. Further research has shown that the reduction of PAHs can be significantly improved under certain conditions and with the use of specific gases.

Summary: This study found that the presence of salted aqueous aerosol suppresses the formation of secondary organic aerosol (SOA) from phenol compounds. Phenol and o-cresol produce phenoxy radicals through photochemical oxidation, which then undergo heterogeneous reactions with salted aqueous aerosol under sunlight and humidity, leading to the suppression of SOA formation.

Summary: Sonochemistry utilizes ultrasound to generate reactive radicals, offering a green alternative for hydrogen production, wastewater treatment, and chemical synthesis. Conventional sonochemical reactors often have design limitations resulting in low efficacy and slow reaction kinetics. A novel reactor design was constructed, creating intense localized high pressure amplitudes capable of spontaneous cavitation, leading to significantly higher hydroxyl radicals production rate and sonochemical efficiency.

Summary: The investigation of cavitation activity during ultrasonic treatment of magnesium particles revealed that the characteristics of cavitation zone may vary depending on the concentration of magnesium particles in the suspension and the nature of the medium. Scanning electron microscopy, X-ray diffraction analysis, and thermal analysis were used to characterize ultrasonically treated magnesium particles, showing the presence of magnesium hydroxide and magnesium hydride in different dispersed media. Furthermore, the incorporation of magnesium hydride in the magnesium matrix was found to be possible by adjusting the conditions of ultrasonic treatment. Additionally, the reactivity of magnesium was confirmed by measuring cavitation activity in various dispersed media.

Summary: The paper focuses on the degradation of recalcitrant pollutants using the sono-photo-ferrioxalate system and provides a critical analysis of process parameters that influence mineralization efficiency. The primary operating parameters that affect the kinetics in the sono-photo-ferrioxalate system are solution pH, temperature, molar ratio of Fe3+/C2O42-, H2O2 concentration, source of light, ultrasound intensity, dissolved gases, and size of cavitation bubble. Multiple oxidizing radicals are generated in this system, such as HO center dot, HO2 center dot, C2O4 center dot-, CO2 center dot- and O-2(center dot-), contributing to degradation.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
