Summary: The effects of various Gd additions on the microstructure evolution, tensile properties, and corrosion resistance of Mg-6Zn-0.5Ca-1Mn (ZMX6105) alloys were examined. The addition of Gd promoted the formation of Ca2Mg6Zn3 phase during solidification and inhibited dynamic recrystallization, resulting in the refinement of dynamic recrystallized grains and strengthening of basal texture. Additionally, the ZMX6105-0.2Gd alloy exhibited excellent tensile properties and optimal corrosion resistance in a 3.5 wt% NaCl solution.

Summary: The micro addition of Ca effectively increases the strength and ductility of Mg-Zn-Ce alloy by enhancing alloying segregation at grain boundary. The addition of Ca leads to enhanced Zn segregation and co-segregation of Zn, Ce, and Ca. This is attributed to the decreased segregation energy and promoted diffusion process of Zn by Ca, which accelerates the thermodynamic and kinetic process of segregation. The controllable segregation at grain boundary, induced by Ca, contributes to the development of advanced magnesium alloys by stabilizing grain boundary, refining grain size, inhibiting dislocation mobility, improving strength, and enhancing grain boundary cohesion and ductility.

Summary: The addition of Ce retards dynamic recrystallization process and results in a bimodal microstructure, with a weakened texture in the DRXed region. The enhancement in strength of Mg-Zn-Ca alloy with Ce addition is attributed to the fine microstructure and strong texture, but it also deteriorates the corrosion resistance in NaCl solution due to the dispersed second phases and weakened basal texture in the DRXed region.

Summary: GFs/ZX50 (graphite flakes/Mg-5Zn-0.5Ca) composites were successfully fabricated by ultrasonic-assisted semi-solid stirring followed by extrusion process. The microstructure observation shows that hot extrusion effectively regulates the orientation of GFs. The GFs/ZX50 composites exhibit excellent thermal conductive property of -145.6-174.2 W/(m center dot K) and high yield strength of -386.8-407.8 MPa. The excellent strength-thermal conductivity synergy of the composites is mainly attributed to the highly orientated GFs, the clean Mg-graphite interface, the ultrafine grains, and the MgZn2 nano-precipitates.

Summary: The effects of Ca addition on the microstructure and mechanical properties of Mg-Zn-Sn-Mn alloys were investigated. With increasing Ca content, the eutectic phase and grains were refined, and the morphologies of the CaMgSn phases changed. Small amounts of Ca can improve properties at room temperature. However, increasing Ca content results in the deterioration of alloy properties. A small amount of Ca can improve the high-temperature plasticity.

Summary: Organic materials with controllable molecular design, such as crystalline quinones, show promise as electrode materials in rechargeable batteries due to their voltage tunability and environmental friendliness. However, the detailed mechanism of proton-coupled electron transfer (PCET) in quinone crystals remains elusive. In this study, the performance of the density functional tight-binding (DFTB) method, specifically DFTB3, in describing charge transport in crystalline quinones was benchmarked. The results highlight the deficiencies of DFTB3 in accurately predicting the proton affinity, structural, and electronic properties of crystalline quinones, calling for further development of the DFTB method in this context.
