Summary: Non-degenerate pump-probe transmission spectroscopy was used to study the ultrafast dynamics of photo-excited carriers in hematite nanoforms. A coupled rate equation model was employed to investigate the formation of self-trapped excitons (STE) and their interaction with free excitons leading to exciton annihilation. The results demonstrate that the majority of excitons are trapped by polaronic trap states and form self-trapped excitons within approximately 3.5 ps. There is a nonlinear interaction between free excitons and STEs, similar to trap-assisted bi-molecular Auger recombination.

Summary: To solve the problem of information storage, a resistive variable memory of Au/Bi2Ti2O7/NiO/ITO was fabricated and its resistive switching characteristics were studied. The device showed diode-like rectifier characteristics and exhibited good durability and stability under 100 cycles of read-and-write tests. At a reading voltage of 0.44 V, the resistive switching ratio of the device reached 102. Combining XPS O 1s spectrum and further analysis of I-V double logarithmic curve, it was found that the conduction mechanism of the device was mainly related to the ohmic conduction mechanism and the space charge limiting current mechanism, and its resistive switching behavior was related to the migration of oxygen vacancies to change the interface barrier.

Summary: Achieving precise control over the 3D morphology of the active layer in all-polymer solar cells is crucial for improving efficiency and stability. This study explores the generation of uniform thin film morphologies using crystallization-driven polymer assemblies in non-halogenated solvents, resulting in well-aligned structures comparable to those prepared with halogenated solvents. The long-term stability of the resulting thin film morphology surpasses that of blend films due to robust intermolecular packing.

Summary: This study investigated the abiotic transformations of the antibiotic sulfamethoxazole (SMX) by intermediates produced during biological nitrogen removal processes, including hydroxylamine (NH2OH), nitrite (NO2-), and nitric oxide (NO). The results showed that while NH2OH was not directly able to transform SMX, NO2- and NO could chemically transform SMX through various reactions. The study also determined the rate constants of SMX with NO2- and NO under different pH and oxygen conditions. The findings enhance our understanding of antibiotic fate during biological nitrogen removal and emphasize the role of reactive nitrogen species in antibiotic degradation.

Summary: In order to enhance the utilization of peroxymonosulfate (PMS) and the stability of catalyst, a dual-reaction center catalyst Cu-Mg0.388Al2.408O4-BN was developed without expensive rare metals. The presence of Mg resulted in a positively charged surface, which facilitated the adsorption of bisphenol A (BPA) and PMS anions under neutral pH conditions. The formation of an electron-rich Cu center was achieved due to the relatively low electronegativity of Mg and the cation-pi interaction between Cu and boron nitride (BN). The combination of electrostatic attraction and dual-reaction center enabled the rapid degradation of BPA through electron transfer and subsequent activation of PMS.

Summary: In this study, the complete defluorination of PFOA using ultrasound/persulfate (US/PS) was investigated, and 100% defluorination was achieved after 4 hours of ultrasound treatment alone. The addition of persulfate suppressed defluorination, possibly due to the increased competition with PFOA for adsorption sites. The study also challenges the previous understanding that defluorination occurs at the bubble-water interface.

Summary: This study investigated the CO3·-mediated oxidation of the frequently detected micropollutant ibuprofen. The results showed that the H atom abstraction pathway dominated the degradation process, regardless of the protonation state. Calculation of the reaction rate constant considering explicit solvent molecules yielded a value in agreement with the measured one. Significant charge transfer was observed from the CO3 center to the solvation shells. The study also constructed a contour plot demonstrating the contribution of CO3·- to the elimination of various micropollutants, highlighting the importance of CO3·- in sunlit surface waters.

Summary: Urbanization and industrialization have negatively impacted water quality, leading to a demand for reliable and eco-friendly treatment technologies. Persulfate-based advanced oxidation processes (AOPs) have shown promise in treating challenging industrial wastewaters and remediating contaminated groundwater. Comparisons of reaction rate constants for different pathways suggest that radical-based AOPs can achieve high removal efficiency with short contact times, while nonradical AOPs are advantageous for complex wastewater treatments with minimal interference. However, nonradical pathways require significantly higher energy requirements. These comparisons inform the prioritization of basic research and the understanding of system-specific application merits and limitations.

A Z-scheme plasmonic photocatalyst Bi-CeO2/Ag-0/BiO2 was designed and fabricated to activate dissolved oxygen in water for micropollutant degradation under visible light. The doped Bi improved the separation of electron-hole and narrowed the band gap of CeO2, while metallic silver (Ag-0) acted as an electronic transmission vehicle in a Z-scheme mechanism.

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.
