Summary: In this study, UV/KI system was used to decompose and defluorinate PFOS. It was found that the system can effectively promote PFOS decomposition and defluorination at a lower concentration of hydrated electron source chemicals and a wider pH range. The decomposition process followed a pseudo-first-order model, and the main products were environmentally friendly ions and acids.

Summary: The study found that aqueous electrons generated in the UV-Na2SO3 system have a good reductive degradation effect on CCl4, efficiently removing it. However, oxygen, inorganic ions, and NOM have a negative impact on the degradation process. The degradation process follows a pseudo-first order kinetic model and is primarily induced by aqueous electrons.

Summary: In this study, a novel approach utilizing hydrated electrons induced by alcohols as catalysts was developed to enhance the decomposition of perfluorooctanoic acid (PFOA). The addition of alcohols not only protected hydrated electrons from quenching, but also improved the dispersion of PFOA in solution, leading to higher yield and utilization efficiency of hydrated electrons. Furthermore, the UV/H2O/alcohol system demonstrated adaptability to different environmental variables, such as solution pH and reaction atmosphere.

Summary: The team synthesized PMAO-KI NPs that can slowly release iodide into cancer cells, enhancing the production of reactive oxygen species induced by radiation therapy. This promotes radiotherapy against breast cancer by causing DNA damage and lipid peroxidation in cancer cells, ultimately leading to tumor eradication in 80% of treated animals without additional toxicity.

Summary: Advanced reduction processes (ARPs) using hydrated electrons (e(aq)(-)), such as UV-sulfite, are effective in treating recalcitrant water contaminants. This study investigated the pH-dependent quenching of e(aq)(-) by dissolved carbonate species and found that H2CO3* dominated the quenching despite being a minor species. The pH-dependent trends in UV-sulfite ARPs can be attributed to the variable acid-base speciation of dissolved carbonate and the sulfite sensitizer.

Summary: Schwertmannite as an adsorbent for Cr(VI) removal has been widely studied, but the photoreduction driven dissolution and fate of Cr(VI) loaded on SCH in the presence of dissolved organic matter (DOM) has been limited. This study examined the effect of tartaric acid (TA) on the stability of SCH-Cr(VI) under simulated solar radiation, showing that TA enhanced the release of total Fe while decreasing total Cr. The mechanism proposed involves reduction of Cr(VI) to Cr(III) by Fe(II) generated from Fe(III)-TA(n) via ligand to metal charge transfer.

Summary: Structural characterization is crucial for understanding protein function. Though electron crystallography can be performed on nanometer-sized crystals and provide additional information, its widespread use has been limited due to the fragility of such crystals. This work demonstrates a methodology to preserve these nanocrystals in their natural environment at room temperature for electron diffraction experiments.

Summary: The electron durability and deterioration mechanism of phenethylammonium (PEA(+))-modified reduced-dimensional metal halide perovskites (RD-MHPs) are systematically studied using an in situ photoelectron spectroscopy technique. The experiment reveals the formation of detrimental metallic lead (Pb-0) and the decomposition of PEA(+) under electron-beam radiation, which changes the photophysical properties of PEA(+)-doped RD-MHPs. These findings provide deep insight into the impact of injected electrons on the performance of PEA(+)-doped perovskite LEDs and offer potential guidance for designing robust and effective organic spacers for RD-MHPs.

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.
