Summary: (1-x)Ba0.5Sr0.5TiO3-xLi(2)MgTiO(4) and (1-x)Ba0.5Sr0.5TiO3-xLi(2)Mg(3)TiO(6) composite ceramics were prepared and their microstructures and dielectric properties were investigated. Both the Li2MgTiO4 phase and Li2Mg3TiO6 phase can coexist with the cubic perovskite BST phase. The dielectric constants of the composite ceramics decrease with increasing Li2MgTiO4 or Li2Mg3TiO6 content, while the dielectric loss remains low and the tunability decreases.

Summary: In this study, the transport properties of van der Waals heterojunctions of two-dimensional atomic crystals were investigated using density functional theory and nonequilibrium Green's function technique. It was found that the formation of heterojunctions does not open the Dirac point of graphene, but preserves the band structures of both graphene and WS2. The origin and mechanism of the unique linear I-V characteristics were revealed through analysis of transmission spectra, density of states, and transmission eigenstate.

Summary: Monolayer graphene and hexagonal boron nitride (h-BN) have excellent barrier properties and are suitable for the development of coating technologies. However, the high electrical conductivity of graphene limits its application in anti-corrosion coatings, and the poor dispersibility of h-BN nanosheets hinders their use as fillers. This study demonstrates a simple method to fabricate highly water-dispersible h-BN nanosheets and incorporate them into ZrO2 coatings, resulting in excellent corrosion resistance and hydrogen isotope barrier properties.

Summary: In this study, a Cu-Cr-Y alloy strengthened by nano-Y2O3 dispersion (ODS Cu-Cr-Y alloy) was prepared by mechanical alloying. The ODS Cu-Cr-Y alloy showed excellent high temperature tensile strength and softening resistance, attributed to the thermodynamic stability of nano-Y2O3 dispersions and the inhibition of Cr nanoparticle growth by Y addition and residual Cr particles. The alloy provides an optimal combination of strength and thermal conductivity at high temperature, making it promising for use as heat dissipation material in severe conditions like fusion plants and rocket engines.

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.

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 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.
