Summary: Extractive desulfurization using ionic liquids has attracted attention due to its simplicity and easy operating conditions. However, the selection of suitable cations and anions remains a challenge. This study developed a methodology to screen cation and anion molecules for maximum sulfur removal efficiency. Through genetic algorithm and principal component analysis, it was determined that certain imidazolium and pyridinium cations combined with specific anions are promising for extractive desulfurization. The selected ionic liquid, [HMPY][N(CN)2], was synthesized and evaluated, showing potential as a solvent for removing DBT or BT from n-heptane.

Summary: In this article, a series of effective catalysts based on betaine and sulfuric or phosphomolybdic acids were obtained. These compositions were characterized and tested in the oxidation of sulfur- and nitrogenous-containing compounds by H2O2. The acidity change is non-linearly influenced by the amount of heteropolyacid (HPA), and the removal of sulfur-containing compounds is correlated with the concentration of Bronsted acid sites on the catalyst surface. On the other hand, the removal of pyridine is primarily determined by the content of heteropolyacids in the catalyst.

Summary: Regulation of Hybrid Materials of Ministry of Education. Bimetallic nanoclusters with synergistic effect exhibit better stability and activity than monometallic nanoclusters in catalytic applications. The influence of calcination temperature on catalytic performance of AuCu24/AC in homocoupling and heterocoupling of terminal alkynes was investigated by fabricating AuCu24/AC-X (X=0, 200, 300, 500, 800) catalysts. The results showed that the catalytic activity of AuCu24/AC-X exhibited a volcanic trend with the increase of X (heat treatment temperature) and the content of Cu2+ also changed with the increase of X. The AuCu24/AC-200 bimetallic catalyst showed the highest catalytic activity in homocoupling and heterocoupling of terminal alkynes under mild conditions.

Summary: Non-thermal plasma (NTP) surface modification technology is a new method for controlling the surface properties of materials. In this study, Cu/ACF adsorbent was modified with NTP to remove H 2 S and PH 3 simultaneously under low temperature and micro-oxygen conditions. The performance test results showed that NH 3 plasma modification had the best removal effect on H 2 S and PH 3 . The NH 3 plasma modification introduced amino functional groups on the surface of the adsorbent and increased the types and number of alkaline sites, thereby improving the adsorption performance. The deactivation of the adsorbent was mainly caused by the consumption of active components and the accumulation of sulfate and phosphate on the surface and inner pores.

Summary: The influence of asymmetric faces on the dynamic failure of fully clamped CFRP/aluminum foam composite sandwich beams under low-velocity impact was investigated. Three types of geometrically asymmetric sandwich cross-sections with equal area density were designed, and low-velocity impact experiments were conducted to examine the dynamic response and failure modes. The results showed initial failure modes of top face fracture, indentation, and core shear, while final failure modes included top face fracture, core shear, bottom face fracture at one end, and debonding between the core and bottom face. It was found that the asymmetric composite sandwich beams with a thinner top face exhibited better impact resistance.

Summary: A high-fat diet is a risk factor for many chronic diseases, and ingesting retrograded starch can help manage hyperlipidemia symptoms by reducing triglyceride and LDL cholesterol levels. The intervention of retrograded starch was found to increase the relative abundance of Bacteroides, which produce propionic acid and had a positive correlation with butyric acid that has anti-inflammatory functions. Thus, retrograded starch intervention may regulate the body's health by altering intestinal bacteria.

Summary: Learning from nature, particularly from the purple orchid leaf, is a promising approach to design superhydrophobic surfaces. By analyzing the wettability difference of the leaf as it grows and its relation to surface morphology, it is found that the presence of well-developed micro-scale basic unit bumps with a dense nano-scale waxy layer contributes to the best hydrophobicity of the mature leaf. The study also demonstrates that the nano-waxy layer is more effective in enhancing surface wettability than the micro-bumps.

Summary: By constructing surface microstructures and improving their hydrophobicity, severe adhesion of biological fluids on surgical electrodes can be effectively reduced. Inspired by purple orchid leaves with self-cleaning properties, the dynamic behavior of water and biological droplets on superhydrophobic microstructured surfaces (SMSs) heated over 100°C was studied. The SMSs with Cassie-Baxter state showed a pseudo-Leidenfrost effect for water droplets, and the dynamic evolution mechanism of plasma droplets on heated surfaces was proposed. The findings contribute to understanding the anti-adhesion mechanism of surgical electrodes at the microscopic level.
