Summary: The technique of mechanical alloying has evolved from producing superalloys for aerospace to synthesizing a wide range of advanced materials, such as nanostructured materials and nanocomposites. This process involves repeated cold welding, fracturing, and rewelding of powder particles to enhance alloy formation. The resulting materials can include supersaturated solid solutions, intermetallics, quasicrystalline alloys, high-entropy alloys, amorphous alloys, and composites, with most having nanometer-sized grain structures.

Summary: Contrary claims have been made regarding the behavior of the honeycomb compound Ag3LiIr2O6, with some suggesting Kitaev spin-liquid behavior and others suggesting ordered behavior. Experimental evidence, including muon spin relaxation and Li-7 nuclear magnetic resonance, confirms the presence of low-temperature magnetic order. Density functional theory calculations further support this finding, indicating an appreciable Heisenberg exchange term favoring magnetic ordering.

Summary: This article reports the effect of nano-structuring and purity on the thermal and thermoelectric properties of alpha-SrSi2. The results show that nanostructured pellets with a grain size of about 200 nm can be obtained using ball milling and spark plasma sintering, which reduces the lattice contribution to the thermal conductivity. The figure of merit ZT is improved to 0.20 around room temperature after nano-structuring. The influence of Sr purity on the thermoelectric properties is also presented.

Summary: The carrier concentration in n-type Bi2Te3-based thermoelectric material is stabilized by high-energy refinement and hot-pressing, combined with SbI3 doping and hot deformation, resulting in optimized carrier concentration and high texture degree. The peak figure of merit (zT) of 1.14 is achieved for Bi2Te2.7Se0.3 + 0.05 wt.% SbI3 sample with a bending strength of 100 Mpa. Additionally, a thermoelectric cooling device consisting of n-type Bi2Te2.7Se0.3 + 0.05 wt.% SbI3 and commercial p-type Bi0.5Sb1.5Te3 legs generates a large maximum temperature difference (Delta T-max) of 85 K at a hot-side temperature of 343 K.

Summary: Mechanical instabilities, such as bistable and multistable mechanisms, have attracted attention for enhancing the capabilities of soft robots and structures. This study proposes a simple approach to overcome the limitations of bistable mechanisms by dispersing magnetically active microparticles and using an external magnetic field to control their responses. The predictable and deterministic control of bistable elements under varying magnetic fields is experimentally demonstrated and numerically verified. This strategy enables precise control of transition waves in multistable lattices and the implementation of active elements for mechanical signal processing.

Summary: In this study, a novel microwave-assisted method was developed to synthesize high-entropy oxide (HEO) nanoparticles. By varying the composition (Cr0.2Fe0.2Mn0.2Co0.2-xNi0.2Znx)3O4 (x = 0, 0.05, 0.1, and 0.2), nanoparticles with uniform distribution of metallic elements and particle sizes ranging from 10 to 50 nm were obtained. The suggested methodology is an excellent synthesis method due to its advantages of ultrafast, low-temperature fabrication of nanoscale and high-purity products at a relatively low cost.

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.

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.

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.
