Summary: Selenide-doped bismuth sulfides (Bi2S3-xSex) were prepared to improve electronic conductivity and interlayer spacing. Anisotropic ReS2 nanosheet arrays were grown on the surface of Bi2S3-xSex to form a hierarchical heterostructure (Bi2S3-xSex@ReS2). This strategy greatly improved the electrochemical conductivity and relieved volume expansion during charge/discharge processes, resulting in outstanding battery performance for SIBs and PIBs.

Summary: Sodium-ion batteries (SIBs) are considered as a promising alternative to lithium-ion batteries (LIBs) due to their abundant resources. Na3V2(PO4)3 (NVP) is a promising cathode material for SIBs, thanks to its unique structure, good stability, and fast sodium diffusion kinetics. However, its weak intrinsic conductivity hinders its further market application. Various strategies, such as foreign ion doping and carbon coating, have been proposed to solve this issue.

Summary: Heterogeneous bimetallic sulfides Bi2S3/Mo7S8 nanoparticles anchored on MXene nanosheets (MXene@Bi2S3/Mo7S8) were prepared and exhibited remarkable rate capability and cycling stability for sodium ion battery. The unique structure between Bi2S3 and Mo7S8 and the high conductivity of Ti3C2Tx nanosheets effectively decreased the Na+ diffusion barrier and charge transfer resistance. The hierarchical architectures of Bi2S3/Mo7S8 and Ti3C2Tx also prevented re-stacking and agglomeration, as well as alleviating volume expansion during charge/discharge processes.

Summary: This study reveals that the mechanism for improving the rate capability of carbonaceous anode through heteroatom doping is not as traditionally believed, which is to increase the diffusion-controlled capacity by expanding the interlayer spacing. Instead, it is found that doping has little impact on interlayer spacing in the bulk phase, but can significantly expand the spacing in the subsurface region when syngergized with tensile stress. This leads to improved accessibility of the subsurface region at high current densities, resulting in higher specific capacity and cycling stability for the electrodes.

Summary: The conversion of single-use non-biodegradable materials into hard carbon for secondary usage is crucial for reducing long-term environmental hazards and manufacturing costs. In this study, floral foam was transformed into hard carbon through a simple high-temperature treatment process, and it exhibited excellent electrochemical performance as a negative electrode in sodium-ion batteries. The favorable electrochemical performances can be attributed to the unique structure of the hard carbon, which enables reversible Na+ ion intercalation and deintercalation.

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.
