Summary: This study investigated the cytotoxicity of chemically relevant imidazolium PILs with different alkyl side chains and compared it with aprotic analogues. The results highlighted the role of anion type in determining the cytotoxicity of ILs with short alkyl side chains. Even low-toxic PILs showed harmful effects on eukaryotic cells when used as cryopreservation agents, and the studied IL/water mixtures tended to form simple solid hydrates due to the weak amphiphilic properties of imidazolium cations with short alkyl side chains.

Summary: Nanoconfinement effect has a significant impact on chemical reactivity. Chemists have designed various porous nanoconfined systems for catalyzing reactions, but achieving effective flow reactions under mild conditions remains challenging. In this study, multilayer aminated graphene oxide (GO-NH2) membranes were prepared to achieve rapid and efficient Knoevenagel condensation with directional flow. By reducing the interlayer spacing of GO-NH2 membranes, the conversion of the reaction increased, reaching nearly 100% at 22 degrees Celsius with a short reaction time when the interlayer spacing was 14.7 angstroms. Mechanistic studies showed that interlayer confinement enhanced the matching of reactants' frontier orbital symmetry. The characterization of catalysts and density functional theory calculation demonstrated that the delocalized pi electrons of graphitic domains on GO-NH2 could reduce the overall confined reaction energy level. This work provides insights for constructing artificial catalytic systems with high conversion under mild conditions.

Summary: In this study, a complexation-distribution separated extraction process was proposed to accelerate the extraction of inert platinum group metals (PGMs). Water-soluble complexes of Ru(III) and Rh(III) with PDA were successfully formed in aqueous solution, and then extracted to the organic phase containing Tf2N- within minutes at room temperature. The use of water-soluble ligands and anionic phase-transfer catalyst proved to be effective in promoting the extraction of PGMs.

Summary: A spiral mosquito-repellent incense-shaped channel was designed and used in a flow electrode capacitive deionization system. Computational fluid dynamics analysis was conducted to study its hydrodynamic performance. The newly designed channel showed low flow resistance and minimal stagnant regions. The effects of flow rate and mass loading on desalination performance were investigated and compared to traditional runway and snake-shaped channels. The MR-shaped channel exhibited a higher salt removal rate. Vortices in the corners of the traditional channels aided in charge transfer.

Summary: Capacitive deionization (CDI) is a novel electrochemical water-treatment technology that utilizes activated carbon (AC) as an electrode material. This study adopted ball milling to produce ball milled AC (BAC) with improved physical and electrochemical properties. BAC exhibited excellent pore structures and favorable surfaces for ion adsorption, leading to reduced electron transfer resistance and ion migration resistance. The average salt adsorption rates and energy-normalized removal salt were significantly enhanced in both membrane capacitive deionization (MCDI) and flow-electrode capacitive deionization (FCDI) using BAC as the electrode material.

Summary: Recently, there has been increasing attention on the development of efficient materials for degradation and detoxification of antibiotics in wastewater treatment. AgVO3, as a visible light active material, has been widely studied for environmental remediation. In this research, a novel heterojunction of AgVO3/rGO/BiVO4 was prepared through a hydrothermal method to improve its efficiency and stability. The results showed that the degradation efficiency of AgVO3/rGO/BiVO4 towards Norfloxacin (NFC) antibiotic was significantly higher compared to pure AgVO3 and BiVO4. The enhanced efficiency can be attributed to the formation of heterojunction and faster charge separation.

Summary: The present study compared the effects of high glucose and glucose fluctuation on apoptosis and autophagy in MC3T3-E1 osteoblasts. The results showed that high glucose and glucose fluctuation decreased cell proliferation and activated autophagy. They also induced oxidative stress, mitochondrial damage, and apoptosis, with more significant differences observed in the glucose fluctuation group. Antioxidant treatment eliminated reactive oxygen species, inhibited autophagy and apoptosis, while autophagy inhibition enhanced apoptosis in the osteoblasts.
