Summary: This article presents a straightforward and low-cost method that combines stereolithography (SLA) and selective electroless metallization (EM) for the fabrication of 3D parts with complex shapes and end-use multifunctionalities. A novel photocurable composite based on acrylate resin loaded with nickel (Ni) particles is developed for high-resolution SLA printing with self-catalytic properties. The metallized SLA cured samples exhibit good electrical and magnetic properties and improved robustness compared to their non-loaded counterparts. Selective metallization of 3D printed parts is achieved through multi-material SLA printing with strong adhesion at the interface, providing a cost-effective approach for rapid prototyping of functional free-form features on 3D structures.

Summary: This study investigates the effect of 2D MAX phase nanoflakes on the plastic deformation process of a copper matrix. The results show that the MAX phase nanoflakes and the interface structure facilitate the initial plastic deformation and achieve significant forest hardening at high strain levels. The interface-induced microstructure evolution also promotes the mechanisms of crack bridging and deflection, enhancing the toughness of the material. These findings provide a possible strategy to simultaneously enhance the strength and ductility by tailoring the geometric shape of reinforcements and their interface with the metal matrix.

Summary: By combining spark plasma sintering and deformation, ultra-high strength steel with good ductility was successfully fabricated in this study. The martensite matrix produced by a distinctive mechanism in spark plasma sintering resulted in ultra-high strength of the specimens, while good ductility was observed in the specimens due to the gradual closing of micro-pores during SPS compression. The high Co-Ni steel produced achieved ultra-high strength and good ductility directly without the need for complicated traditional heat treatment processes.

Summary: Aluminum oxynitride ceramics doped with different sintering aids were synthesized, and their microstructures, mechanical, and optical properties were investigated. The results showed that the optimal amount of sintering aids was 0.06 wt% La2O3 + 0.16 wt% Y2O3 + 0.30 wt% MgO. The addition of La3+ and Mg2+ decreased grain boundary migration, promoted pore elimination, and inhibited grain growth. The addition of Y3+ facilitated liquid-phase sintering. Furthermore, the addition of Mg2+ effectively promoted twin formation, hindering crack propagation and dislocation motion. The doped AlON ceramic exhibited excellent mechanical and optical properties.

Summary: Extensive research has revealed that oxygen evolution reaction (OER) in alkaline conditions involves dynamic surface restructuring. The development and design of sulfide/oxide pre-catalysts can reasonably adjust the composition and structure after surface reconstruction, which is crucial for OER. This study utilized a simple two-step hydrothermal method to achieve in situ S leaching and doping, inducing the composition change and structure reconstruction of CoFe oxides. The transformed FeOOH and CoOOH exhibited excellent OER activity and could be easily mass-produced using low-cost iron based materials and simple methods.

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

Summary: In this study, six bimetallic FeCo particles were synthesized via the hydrothermal method at different Fe:Co ratios. The Fe:Co ratio not only modulates the composition of the particles but also influences their structure and magnetic properties. The FeCo alloys showed a transformation from an Fe-based structure to a Co-based structure with increasing Co content. The Fe:Co ratio of 1:1 and 3:1 resulted in particles with the highest and lowest saturation magnetization, respectively.

Summary: We conducted a study on the formation of ultra-fine Y-Ti-Ta-O nano-oxides in Ta+B micro-alloyed 13CrWTi-ODS alloys using electron microscopy and first-principles calculations. The Y-Ti-Ta-O nano-oxides were found to be mainly Y2(Ti,Ta)2O7, with an average size of 7 nm and a number density of 6.8 x 1023 m-3. Excess boron was found to enhance the adhesion of some low-sigma grain boundaries but weaken the Fe/Y2Ti2O7 interface, while excess tantalum enhanced the Fe/Y2Ti2O7 interface but caused serious degradation of grain boundaries.

The redistribution of Co2+ and Fe3+ ions between octahedral and tetrahedral sites was observed due to Mn2+-Tb3+ co-doping. The coercivity and magnetization saturation of co-doped samples were significantly improved, leading to a maximum energy product that is 190% higher than that of the un-doped sample.

Summary: Recently, there has been an increasing interest in developing ultra-fine nanostructured electrodes with extensive reaction areas to enhance the performance and low-temperature operation of solid oxide fuel cells. The use of a refined approach involving co-sputtering metal alloys and oxide targets has demonstrated the feasibility of nano-columnar structures in perovskite-based electrodes, expanding the temperature range of thin film electrodes. This study systematically examines the effects of chamber pressure control in the co-sputtering process and identifies the intricate relationship between sputtering pressure and film structure. By fine-tuning the columnar growth in the electrode, significant improvements in performance and thermo-mechanical properties were achieved, resulting in high-performance all-sputtered solid oxide fuel cells.
