Summary: The synthesis and characterization of a new Cu(II) complex with a bidentate Schiff base were reported. The structure of CuL2 was determined using single crystal X-ray diffraction, revealing a square planar geometry with two naphthyl substituents perpendicular to the molecular plane. Additional analysis was conducted using IR and UV-Visible spectroscopy techniques. The catalytic activity of CuL2 in the oxidation of primary and secondary alcohols was investigated, with TBHP and imidazole identified as an effective oxidant/additive combination.

Summary: In this study, excellent H2S removal performance was achieved by wet scrubbing persulfate solution combined with UV irradiation. The H2S removal efficiency was enhanced with the increase of UV power and initial (NH4)2S2O8 concentration, but restrained with the increase of initial H2S concentration and gas flow. Free radicals of sulfate radicals and hydroxyl radicals played a leading role in H2S oxidation in the advanced oxidation process.

Summary: The efficient synthesis of amino acid Schiff base copper(II) complexes was achieved using a microfluidic device. Schiff bases and their complexes are highly biologically active and catalytic. A conventional beaker-based method required a reaction time of 4 hours at 40 degrees C, but in this study, a microfluidic channel enabled quasi-instantaneous synthesis at room temperature (23 degrees C). The products were characterized using UV-Vis, FT-IR, and MS spectroscopy. The efficient generation of compounds using microfluidic channels has the potential to greatly contribute to drug discovery and material development due to high reactivity.

Summary: Sulfate radicals (SO4 center dot- )-based advanced oxidation processes have gained significant attention for their high catalytic activity in treating water pollutants. The combination of iron-based materials with peroxymonosulfate (PMS) or persulfate (PS) is an effective way to generate reactive sulfate radicals. The analysis of different heterogeneous iron-based catalysts for PMS or PS activation provides insights into their microstructure, electrical properties, and the effects of various engineering approaches on activation.

Summary: In this study, mackinawite (FeS) was used to activate persulfate (PS) for the removal of tetracycline (TTC). The effect of coexisting Cu(II) on TTC degradation was investigated at different initial pHs. It was found that at an initial pH of 3, nearly 100% removal of TTC was achieved in 5 minutes, with or without Cu(II). Furthermore, a significant increase in the degradation rates of TTC was observed in the presence of Cu(II) at an initial pH of 9.

Summary: A new ethynylated Schiff base complex, [Cu(SALANI)2], was synthesized and characterized. The 1H NMR spectra of the complex were obtained and interpreted despite its paramagnetic character. Polyacetylene-type micro/mesoporous organometallic networks were prepared by copolymerization with appropriate monomers or by postpolymerization metalation. The new porous organometallic networks exhibited a high specific surface area and Cu2+ content, and showed catalytic activity in the oxidation of linalool to linalool oxide.

Summary: Despite the advances in understanding flexibility in organic single crystals and their defect-free packing, they are rarely used in electronic devices. This study reports on the modulation of mechanical flexibility and fluorescence of pyrene-functionalized naphthalidenimine single crystals in response to chemical stimuli. Crystallographic investigations reveal that subtle changes in weak intermolecular interactions play a crucial role in defining the mechanical flexibility of these crystals. Furthermore, the multi-stimuli responsive properties of these single crystals are used to build a multiple-input, multiple-output molecular logic gate.

Summary: A novel sandwich-like alpha-ketoglutaric acid Schiff base-aminated chitosan composite (alpha-kGl-AmCsSB) was synthesized by reacting alpha-ketoglutaric acid and aminated chitosan. The morphology, surface charge, and chemical composition of alpha-kGl-AmCsSB were analyzed by various characterization tools, confirming the successful formation and linkage between alpha-kGl and AmCs. It exhibited high adsorption efficiency for Congo red (CR) with a maximum adsorption capacity of 434.78 mg/g at 25°C and pH 3, and followed a pseudo-second-order model for adsorption kinetics. The adsorption mechanism was proposed and discussed, and the material showed excellent reusability with a recycling rate above 72% for five cycles.

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: 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.
