Summary: Grain refinement is essential for powder bed fusion additive manufacturing, and this study investigated the effects of different grain refiners on the grain size of Al-2 wt%Cu alloys. The results showed that Ti and Zr were the most effective grain refiners, while V and W had detrimental effects on grain refinement. Additionally, the addition of B also significantly contributed to grain refinement. The relationship between lattice parameters and grain size, as well as epitaxial strain/lattice match, was not clearly established.

Summary: In this study, (La0.2Nd0.2Sm0.2Gd0.2Yb0.2)2Zr2O7 (Ln2Zr2O7) ceramic powders with nanoscale were synthesized using the concurrent chemical coprecipitation method. The thermal behaviors and structural evolution of the Ln2Zr2O7 precursor were investigated. The results showed the formation of a complex polymeric compound in the precursor, which transformed into Ln2Zr2O7 crystals through calcination. The bulk Ln2Zr2O7 ceramics displayed a lower thermal conductivity due to the high-entropy effect resulting from the introduction of multiple rare earth elements.

Summary: Flame-retardant CaAl-PO4-LDHs were synthesized via the coprecipitation method using PO43- as the anion of an intercalated calcium-aluminum hydrotalcite to improve the flame retardancy of bamboo scrimber. The CaAl-PO4-LDHs were characterized and used as flame retardants for bamboo scrimber, and their effects on flame retardancy were evaluated. The results showed that the CaAl-PO4-LDHs significantly decreased the peak heat release rate, delayed the time to exothermic peak, increased the Time to Ignition, and reduced the production of CO and CO2 in the bamboo scrimber.

Summary: The effect of adding cobalt salt on the growth mechanism of coatings prepared on the surface of 2024 aluminum alloy by micro-arc oxidation was investigated. The addition of cobalt salt prolonged the spark discharge phase and achieved co-film formation. Changes in the physical composition, surface morphology, and chemical composition were studied using XRD, SEM, EDS, and XPS. The addition of cobalt salt significantly promoted the formation of alumina in the coating, leading to enhanced hardness and corrosion resistance. The coating prepared in cobalt-containing electrolyte for 60 minutes showed the best corrosion resistance.

Summary: Environmental problems caused by fossil energy utilization have led to increased focus on renewable energy. This study synthesized NiCo2O4 as a catalyst for biomass pyrolysis and evaluated its performance in toluene pyrolysis and hydrogen production. The results showed that NiCo2O4 effectively pyrolyzed toluene at 300 degrees C, with a hydrogen yield of 0.6%. In the longevity test, toluene could be completely pyrolyzed for at least 5 hours at 400 degrees C, maintaining a high hydrogen yield of above 80%. The study suggests that NiCo2O4 has potential as a catalyst for ultra-low temperature biomass pyrolysis to produce hydrogen.

Summary: Cobalt hexacyanoferrate (CoFe(CN)6; CoHCF) was synthesized as a cathode material for Na-ion aqueous batteries at different solution temperatures. It was found that low temperature synthesis resulted in small particles with high defects, which exhibited good rate performance and high Na accommodation; while high temperature synthesis produced large particles with fewer defects, but lower specific capacity due to irreversible redox reactions.
