Summary: This research investigates the rheological behavior and microstructure evolution of CoCrFeMnNi high-entropy alloy (Cantor alloy) during UV-assisted deformation. It is found that Cantor alloy exhibits an unusual acoustic residual softening (ARS) phenomenon, which is related to the alleviation of severe lattice distortion effect and the increase of stacking fault energy during the UV process. Mathematical models are developed to quantitatively characterize the ultrasonic softening (US) and ARS, which can well predict their influences.

Summary: In this study, κ-carrageenan (κC) and transglutaminase (TG) were used to modify fish gelatin (FG). Three types of modified gelatin groups FG-κC, FG-TG, and FG-κC-TG were prepared. Results showed that κC and κC-TG complex modification greatly enhanced the gel strength and textural properties of FG gels, while pure TG modification weakened the gelling properties. The pure 0.1% κC modified FG had the highest gel strength and hardness. Rheological behavior indicated that the complex modified FG samples had the highest viscosity, gelling points, melting points, and G'∞.

Summary: This study investigated the thermal, electrochemical, and mechanical properties of Zn-30Sn solder alloy with different contents of CrFeCoNiCu high-entropy alloy (HEA) (0, 0.5, and 1 wt%). Ultrasonic stirring was introduced into the melting process. The results showed that the addition of HEA refined the microstructure and increased the precipitation phases. Ultrasonic treatment dispersed the phases and facilitated the formation of dense and uniform corrosion products. The Zn-30Sn solder alloy containing 1.0 wt% HEA exhibited the lowest corrosion current density, highest mechanical properties, and slightly decreased melting temperature.

Summary: The comprehensive mechanical properties of a low Y and Ni containing magnesium alloy can be further improved by doping with Al element and ultrasonic vibration treatment. Doping Al into the alloy reduces the amount of LPSO structure and precipitates Al2NiY phases near the block LPSO structure. Ultrasonic vibration treatment modifies the Al2NiY phase into short flakes and distributes them uniformly in the matrix.

Summary: Melting point is one of the defining characteristics of ionic liquids (ILs) and plays a crucial role in their selection for various applications. The development of predictive tools is essential to estimate the physiochemical properties of ILs, and the prediction of melting point is the starting point for such approaches. Previous attempts to predict IL melting point using group contribution methods have had limited success due to the complex relationship between IL structure and melting point. In this study, a new hybrid group contribution method is proposed based on an extensive database of IL melting points, combining functional group parameters with simple structural parameters. The new method performs better quantitatively and qualitatively than the standard group contribution method.

The adsorbent showed enhanced thermal stability and porous surface. Optimum conditions for phenol removal were determined, and the adsorption process followed pseudo-second order kinetics and fitted the Freundlich isotherm model. The adsorbent could be regenerated and reused for at least four cycles without significant loss in adsorption efficiency.

Summary: This study measured the thermal conductivities of nine different bis-((trifluoromethyl)sulfonyl)imide-based ionic liquids using the modified transient plane source method. The thermal conductivities of all the studied ILs decreased with increasing temperature and fell within the reported range for ILs. Two extended group contribution models were tested and yielded average absolute relative deviations of 5.5% and 4.9% respectively for the entire dataset.

Summary: Polyurethane foams (PUFs) are widely used but highly flammable, and the development of PUFs with fire-retardant properties is crucial. Graphene-based nanomaterials (GNs) improve the thermal stability of PUFs and delay ignition. However, the sheet structure of GNs affects their dispersion and compatibility, which can be addressed through modification.

Summary: The use of Ag-RGO as an antibacterial agent in water-based acrylic paints was investigated. The nanocomposite showed strong antibacterial activity against E. coli and S. aureus. Increasing the concentration of Ag-RGO in the paint enhanced the inhibition efficiency. Microscopy images revealed that the bacteria's lengths decreased and degraded after 24 h of exposure to the antibacterial paint. The antibacterial activity of Ag-RGO against S. aureus was higher than that against E. coli.

Summary: In this study, the aggregation and possible coalescence of a pair of core-shell Pt@Au nanoalloy particles were simulated in different solvents. The results showed that the tendency for aggregation is greater in water and benzene + water systems, weaker in IL, ethanol, and benzene, and there is a very small change in the structure of the nanoalloys in different solvents. The study also examined the effects of nanocluster shape and core by simulating truncated octahedral (Au)374 and pure icosahedral (Au)309 nanoclusters in water.

Summary: Sulfur dioxide emissions from fossil fuel combustion can have negative impacts on health and the environment. The current hydrodesulfurization method used by refineries has limitations in producing ultralow sulfur diesel at reasonable costs. Ionic liquids have been explored as potential alternatives, but there is limited research on their industrial-scale feasibility and integration into process simulators. This study screened and evaluated 26 commercially available ILs for desulfurization of diesel fuel using COSMO-based models and Aspen Plus, and proposed an optimized process using 1-butyl-3-methylimidazolium thiocyanate that achieves ULSD with minimal loss of the IL.

Summary: Producing freshwater from seawater and wastewater is important, and a three-dimensional carbonized pine cone (CPC1) was fabricated as a low-cost and efficient photoabsorber for this purpose. CPC1 exhibited high conversion efficiency and evaporation flux due to its large solar-light-harvesting ability, porosity, rapid water transportation, water/air interface, and low thermal conductivity. It also showed good stability and the ability to purify seawater and wastewater through the removal of organic dyes and reduction of polluting ions.
