Summary: Dilution of ionic liquid with appropriate cosolvents can modify the physicochemical properties, and even low concentrations of cosolvents can lead to significant changes in their dynamics. Molecular dynamics simulations were used to study the impact of cosolvent polarity on the motional features of ionic liquids.

Summary: In this study, molecular dynamics (MD) simulations were used to investigate the electrical behavior of atomic charges of a fullerene in an ionic liquid. By combining solute-solvent configurations and density functional theory (DFT) calculations, the convergence of atomic charges and dipole moment during the dissolution process was obtained through an iterative process of MD simulations and DFT calculations. A comprehensive analysis of atomic charge behavior was conducted to examine the impact on solute-solvent structure, highlighting the importance of complete solute polarization in the solution. Additionally, quantum calculations of nuclear magnetic resonance (NMR) and absorption spectra were performed to observe the impact of electronic C-60-solvent interaction on spectroscopy results, revealing a smaller chemical shift and a more intense electronic transition band for the fully polarized C-60 in solution.

Summary: This study investigated the dissolution of waste wool using an ionic liquid solvent and an additive, and found that the additive enhanced the solubility of keratin. The dissolution process resulted in a reduction in molecular weight and degradation of the keratin structure. However, the protein nature and function of keratin were retained. The study also suggested that the solvent and additive could induce minor structural alterations in wool without significantly modifying its properties.

Summary: Here, we present a novel electrochemical sensing mechanism for ammonium ions (NH4+) which involves the two-electron oxygen reduction reaction (ORR) and the hydrazine reaction. By using a self-supporting Ag/TiO2 nanotube array composite electrode modified with hematite (Ag/Fe2O3/TNTs), NH4+ can be electrooxidized to hydrazine by H2O2 produced from the ORR. The Ag/Fe2O3/TNT sensor exhibits high sensitivity, short response time, fine selectivity, and good reproducibility, making it suitable for accurate detection of NH4+ in real water samples. Moreover, this mechanism shows certain universality in various Ag/transition metal oxide/TNT sensing systems, providing a new design basis for electrochemical ammonia nitrogen sensors that are urgently needed.

Summary: The concentrations of terrestrially sourced dissolved organic matter (DOM) in aquatic ecosystems have increased in recent decades. The mechanisms of organic matter-mineral interactions, one major pathway for soil organic matter sequestration, are not well understood. This study investigated the effect of calcium phosphate mineralization on humic acid (HA) fixation in simulated soil solutions with or without clay mineral montmorillonite (Mt). It was found that Mt promoted nucleation and crystallization of calcium phosphate, contributing to the long-term persistence and accumulation of HA. The findings highlight the crucial role of Mt in DOM sequestration and suggest knowledge gaps that can improve soil C sequestration.

Summary: In order to achieve a high separation efficiency of photogenerated carriers in semiconductors, constructing high-quality heterogeneous interfaces as charge flow highways is critical and challenging. This study successfully demonstrates a new strategy for constructing high-quality heterogeneous interfaces by consciously modulating interfacial chemical bonds and internal electric fields (IEFs) in a 0D/0D/1D-Co3O4/TiO2/sepiolite composite catalyst. The results show that the interfacial Co2+-O-Ti bond plays a major role as an atomic-level charge transport channel at the p-n junction, and increasing the Co2+/Co3+ ratio enhances the IEF intensity, thereby enhancing the photoelectron separation and migration efficiency. The study also shows the efficient synergy between photocatalysis and peroxymonosulfate activation for deep pollutant degradation and reduced ecotoxicity.

Summary: With the advancement of nanotechnology, micro/nanorobots (MNRs) have emerged as promising medical tools with their precise navigation capability. However, simulating the motion mechanism, functional strategies, and adaptability of MNRs in complex dynamic environments remains challenging due to the complex biological interactions and limitations of current experimental methods. Finite element analysis (FEA) has become an effective method in MNR research by simulating the motion mechanism, proposing theoretical models combined with experimental results, and reducing experimental errors. This review introduces the design, driving mechanism, solutions for dynamic environments, and application of FEA in MNR research, summarizing the current challenges and future directions.
