Summary: This study prepared cyanobacterial biochars enriched/doped with non-metallic elements by pyrolysis of biomass amended with different N, S, and P containing compounds. It was found that P doping significantly improved the catalytic reactivity of the biochar, with organic phosphorus dopants showing the best performance. Post-acid-washing further enhanced the catalytic activity, especially the acid-washed triphenyl-phosphate doped biochar, which exhibited the highest degradation rate and NOR mineralization. The high reactivity of P-doped biochar was mainly attributed to its large specific surface areas, high adsorption, high C-P-O content, graphitic P, and non-radical degradation pathway.

Summary: This study investigates the oxidation of the antibiotic norfloxacin (NOR) using cyanobacterial nitrogen rich biochars (CBs) as catalysts for peroxydisulfate (PDS). The results show that CB950, pyrolyzed at 950 degrees C, is highly effective in degrading NOR, with a faster degradation rate compared to low pyrolysis temperature (PT) CBs. The high pyrolysis temperature CBs also exhibit full reactivity after repeated uses and high defluorination and mineralization rates. The study suggests that high pyrolysis temperature biochars from algal bloom biomass can be used as catalysts for organic contaminant oxidation.

It also discusses the application of biochar-based multifunctional nanocomposites in activating PMS to remove PPCPs, along with the influencing factors and degradation mechanisms involved. Additionally, the study proposes future research directions for the industrial application of biochar-based nanocomposites. Overall, this study provides valuable insight for the efficient removal of PPCPs using biochar-based catalysts in PMS-AOPs.

Summary: The application of heterogeneous advanced oxidation processes (AOPs) in wastewater treatment is hindered by low oxidant utilization efficiency, slow catalytic cycling, and matrix interference. This study demonstrates that amorphous zirconium dioxide (aZrO2), a redox-inert metal oxide, can efficiently activate peroxymonosulfate (PMS) to degrade organic micropollutants even under low oxidant doses and complex matrices. The surface Zr(IV)-PMS* complex is identified as the principal reactive species, and the interaction between Zr atom and PMS leads to prolonged O-O bond and elevated oxidation potential for direct reaction with contaminants.

Summary: Currently, medical image classification algorithms are crucial in clinical diagnosis. However, these algorithms still face limitations due to lack of data labels, small sample size, uneven distribution, and poor domain generalization. To address these issues, a deep learning training network for disease classification and recognition of multimodal few-shot medical images is proposed, incorporating meta-learning, transfer learning, and few-shot learning methods. The network also combines the multi-source domain generalization method from person re-identification field to improve its structure. Experimental results verify the applicability and effectiveness of the model, showing better accuracy than advanced models in this field and similarity between classified areas and manually labelled areas. This research has far-reaching significance in enhancing future clinical auxiliary diagnosis, patient diversion, and promoting the development of Wise Information Technology of Med.

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.
