Summary: This study focused on improving the mixing effect of hydrogen peroxide in ozone-based advanced oxidation processes by modifying the injection facility. CFD analysis revealed that conventional diffuser systems were inefficient for mixing oxidizer and feed water, suggesting the need to increase the number of diffusers to improve hydrogen peroxide injection flow. Further research is needed to explore the dissociation and reaction between hydrogen peroxide and contaminants or scavengers.

Summary: Microbial desalination cells (MDCs) are bioelectrochemical devices that recover energy and chemicals from organic wastes while desalinating saltwater. Using MDCs to produce H2O2 can reduce the salinity of feed water and disinfect microorganisms, alleviating the energy requirements and biofouling of reverse osmosis (RO) processes. The combination of H2O2-producing MDCs and UV-based advanced oxidation process (AOP) showed high desalination efficiency and microorganism inactivation kinetics.

Summary: Organic contaminant abatement by upgraded electrochemical process is highly efficient. An electrochemical advanced oxidation process is developed by combining in situ electro-generation of persulfate on beta-PbO2 anode and hydrogen peroxide on carbon cathode. The presence of reactive species, such as 1O2, ·OH, and SO4·-, produced on-site contributes to the strong oxidant power and mineralization. The application of oxygen-depolarized electrode not only produces hydrogen peroxide but also reduces cell voltage and energy consumption.

Summary: Solar water splitting is a promising approach for converting sustainable solar energy into hydrogen production. Compared to the conventional four-electron process for producing hydrogen and oxygen, a two-electron process with simultaneous production of hydrogen and hydrogen peroxide is more attractive as it allows for spontaneous product separation. This article introduces two-electron solar water splitting from both thermodynamic and kinetic perspectives and assesses the critical issues involved in this process. It also presents technoeconomic analysis and research opportunities to promote the development of this promising technology for practical applications.

Summary: Hydrogen peroxide is a crucial chemical attracting attention for energy and environmental applications. The environmentally friendly solar-driven production of hydrogen peroxide, which only requires water, oxygen, and light energy, has gained the most attention. The rational design of functional photo-responsive catalysts promotes hydrogen peroxide production in photo(electro)catalytic approaches. This review systematically summarizes strategies for these catalysts and discusses prevailing hypotheses, state-of-the-art catalysts, critical challenges, and perspectives to enhance comprehension and promote interest in sustainable hydrogen peroxide production.

Summary: The simultaneous removal of oxytetracycline (OTC) and phosphate (P) in water by O-3/CaO2 advanced oxidation process was studied. Increasing the CaO2 dosage enhanced the degradation efficiency of OTC and the removal efficiency of P. Higher amount of O-3 had a positive effect on the removal efficiency of OTC but had little effect on the removal efficiency of P.

Summary: The effect of the two-way injection method during copper chemical mechanical planarization (CMP) process was investigated. The two-way slurry-injection method not only prevents slurry degradation but also shortens the process time by eliminating the need for slurry and H2O2 mixing. Compared to the conventional method, the two-way injection method has a material removal rate equivalent to less than 9%. Particularly, when injecting near the center of the pad, the influence of nozzle positions and flow rates is negligible, making it a worthy slurry-supply method to study.

Summary: This study systematically characterized the binding of ASK and BSA to understand the pharmaceutics properties of the ligand and the conformational changes of BSA upon the addition of ASK. The results indicated a temperature-dependent binding constant between ASK and BSA. Thermodynamic analysis revealed viable hydrophobic and hydrogen bonds in the moderate-affinity complex formation. CD spectroscopy showed changes in the secondary structure of BSA, with an increased content of alpha-helices upon the addition of ASK. AFM and DLS techniques demonstrated slight conformational shrinkage and the formation of large particles upon ASK binding. Molecular modeling suggested allosteric modulation of BSA structure in the vicinity of the tryptophan residue. Overall, the results of ASK-BSA interaction have significant implications for expanding the bio-applications of shikonin.

Summary: A microplastic sampling device was designed and developed to obtain a high recovery rate of microplastics and prevent contamination. The device was evaluated using microplastic reference materials and computational fluid dynamics analysis. It has the capability to process both large (100 μm) and easily contaminated microplastics (around 20 μm), achieving a recovery rate of 94.2% and separating particles through filtration. This method improves the accuracy and reproducibility of microplastic contamination results and facilitates consistent collection and management of microplastic data.
