Summary: In this work, the effect of newly synthesized polymeric borate ester (PBE) additives on the electrochemical performance of high-capacity silicon-graphite (Si-C) anode was investigated. The results showed that the PBE additive exhibited excellent electrochemical stability and improved battery performance in carbonate electrolyte solutions. The improvements in cycling performance were attributed to changes in electrode morphology and the formation of a stable solid electrolyte interface (SEI) layer.

Summary: The choice of proper solid electrolyte interphase (SEI) additives is important for the formation of a stable SEI layer that protects the necessary electrolyte components in a battery. The study investigates the reduction pathways followed by the solvent and additives during SEI formation and highlights the significant role played by additives in determining the extent of SEI formation. The results suggest that for Al batteries, VC additives with EC solvents may be a better choice for a stable SEI layer.

Summary: The use of self-protected Solid electrolyte interphase (SEI) in carbonate-based electrolyte with Vinylethylene carbonate (VEC) additive offers a solution to the issues faced by lithium metal batteries during charging. The addition of VEC prevents lithium salts and solvent decomposition, forming a self-protected highly uniform and mechanically strong SEI layer on the lithium metal surface. This results in uniform lithium plating/stripping and high Coulombic efficiency, leading to improved cycling stability and rate capability in lithium metal batteries.

Summary: This study investigated the effects of fluoroethylene carbonate (FEC)-induced solid-electrolyte-interface (SEI) layers on carbon-based anode materials for potassium ion batteries (PIBs) and achieved a remarkable enhancement of cycling performance. By adding a small amount of FEC (0.2 wt%) in a carbonate-based electrolyte system, a well-balanced organic-inorganic hybrid SEI layer was formed, effectively blocking additional electrolyte decomposition and significantly improving Coulombic efficiency and capacity retention. Additionally, the FEC additive reduced the self-discharge rate, demonstrating its beneficial effect on cycling stabilities.

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.
