Summary: This study investigated the spraying quality of four different coating methods and their effect on mango coating preservation. The results showed that dip coating method formed the smoothest and flattest film surface. Electrostatic spraying method was able to spray finer droplets and had the highest transfer efficiency. Both electrostatic spraying and dip coating methods showed similar preservation indices for mango coating. Electrostatic spraying method could save coating solution and drying time, reducing production costs and achieving continuous and automated coating operations.

Summary: Using 3D printing technology to prepare ceramic shells for precision investment casting offers a quick and efficient preparation process, but often results in low strength and accuracy. This paper proposes a silica sol room temperature dip coating treatment combined with high temperature sintering method to improve the strength and surface precision of ceramic shells prepared using binder jetting. The study shows that increasing the sol concentration and dip coating time significantly improves the mechanical properties and surface precision of the alumina ceramic shell.

Summary: This paper discusses the successful deposition of mono- and double-layer coatings of silane-Al2O3/multi-walled carbon nanotube (MWCNT) nanocomposites on magnesium alloy (AZ91) to enhance its corrosion resistance. Various characterization techniques were employed to evaluate the performance of the coatings with different MWCNT contents. Results showed that incorporating an appropriate amount of MWCNTs improved the corrosion resistance, with the double-layer coating showing better performance. This coating system has the potential to effectively protect AZ91 magnesium alloy against corrosion.

Summary: Developing highly efficient bifunctional oxygen electrocatalysts is crucial for zinc-air flow batteries. Metal-organic frameworks (MOFs) and covalent organic polymers (COPs) have emerged as promising alternatives due to their designable and controllable atomic-level structures. However, their catalytic performances are limited by conductivity and catalytic activity. In this study, nanosheet FeNi-MOF and iron phthalocyanine rich COP hybrid materials are assembled through the pi-pi stacking effect to create highly efficient bifunctional electrocatalysts. The resulting catalyst exhibits superior catalytic performance and stability, making it a promising candidate for zinc-air flow batteries.

Summary: In this study, we modified the electrolyte cubic plus association equation of state (e-CPA EoS) and integrated it with two electrical conductivity models to estimate the electrical conductivity of 11 monovalent electrolyte solutions in water. The modified e-CPA model demonstrated better performance and the hybridization with electrical conductivity models resulted in two predictive models for estimating the electrical conduction of dilute and concentrated electrolyte solutions. These predictive models showed relative average percentage deviations (AARD) of 11.15% and 13.87% over wide ranges of temperature and electrolyte concentration.
