Summary: This study focused on the production of [Cu-10 Ni](x)-x wt% Si3N4 nanocomposites through mechanical alloying followed by spark plasma sintering. The results indicated that the incorporation of Si3N4 nanoparticles decreased the matrix powder particle size considerably and improved the compression strength of the sintered samples through stronger bonding and grain refinement.

Summary: This study explores intentionally doping high entropy alloys with non-metallic species to precipitate ordered phases and enhance hardness. The successful doping of nitrogen resulted in multiple nitrogen-rich secondary phases, including a unique ordered laminar phase and a complex carbonitride. Long term aging treatments and comparison with undoped alloys confirmed that intentional formation of complex nitride phases greatly increased the hardness by up to 3-4 GPa.

Summary: The microstructure and hydrogen storage properties of as-cast and annealed TiFe-6 wt % ZrCr2 alloy samples were investigated. Both samples exhibited three phases, with the amount of TiFe2 significantly reduced and fragmented in the annealed sample. Both samples were able to be hydrogenated under 31 bar of hydrogen at room temperature, with the annealed sample requiring an incubation period of around 40 hours.

Summary: Nanocrystalline alpha-ZnSe was successfully synthesized by mechanical alloying, forming a homogeneous phase after 1 hour of milling without further changes observed up to 10 hours. The minimum crystallite size achieved was 9 nm. Annealing the powder at 1000 degrees C for 1 hour resulted in an increase in lattice parameter, indicating a contraction in the nanocrystalline state and reaching equilibrium upon annealing. SEM and EDS techniques confirmed the XRD results. These findings demonstrate the synthesis of a homogeneous alpha-ZnSe phase during milling and an increased homogeneity range of the phase.

Summary: Nanocrystalline and α-ZnSe were synthesized by mechanical alloying. XRD studies showed a homogeneous phase formed after 1 hour with no further changes. The minimum crystallite size achieved was 9 nm. Annealing increased the lattice parameter, suggesting contraction in the as-milled condition and reaching equilibrium on annealing. SEM and EDS techniques confirmed the XRD results. These new findings demonstrate the formation of a homogeneous α-ZnSe phase during milling and an increased range of homogeneity.

Summary: The TiZrNb metal-matrix composites reinforced by in-situ formed borides were produced using different amounts of TiB2. The composites exhibited varying microstructures and mechanical properties with the increase in boride content. Load transfer strengthening was found to be the main contributor to the overall strength of the composite. The biocompatibility evaluation suggested a decrease in the proliferation rate of mesenchymal stem cells with an increase in boride content.

Summary: This article proposes a new method for serial section registration using an unsupervised optical flow network to measure feature similarity and eliminate nonlinear deformation. The optical flow network is also used to estimate and compensate for cumulative registration error, enabling the reconstruction of biological tissue structures. Experimental results demonstrate that this method effectively improves the spatial continuity of serial sections and enhances the accuracy of registration and reconstruction for biological tissue structures.

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.

Summary: The structure and magnetism of cobalt ferrites after Mn2+-Tb3+ co-doping were studied. Co-doped samples exhibited cubic spinel structure and spherical shape of ferrite nanoparticles. 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.
