Summary: The introduction of a charge collector needle in the traditional architecture of TENG allows for the conduction current, resulting in a new water tube TENG (DcCc-TENG) with high instantaneous power. Through a detailed physical process model, it is revealed that the high instantaneous power output of DcCc-TENG is based on the synergistic enhancement mechanism of displacement and conduction currents. The experimental results demonstrate a high instantaneous volumetric power density of 16.6 W/m(3) for a single device, capable of powering more than 120 LEDs, and the potential application of DcCcTENG is further demonstrated in a ship attitude sensor.

Summary: The nanoarchitecture of transition metal oxides is considered crucial in supercapacitor electrode materials. In this study, Co3O4 doped with transition metals (Ni, Mn, and Zn) was synthesized using a simple co-precipitation technique. X-ray diffraction analysis showed a face-centered cubic lattice for Co3O4, with slight variations in lattice parameters when iso-valent metals were doped at the Co site. The incorporation of a nominal amount of Ni, Mn, and Zn resulted in a favorable porous morphology and increased porosity. Electrochemical measurements revealed that Mn0.05Co2.95O4 displayed the highest specific capacitance of 80.8 F/g, making it a potential candidate for electrochemical supercapacitor applications.

Summary: Tin shows promising potential for aqueous batteries due to its multiple electron reactions, high corrosion resistance, large hydrogen overpotential, and excellent environmental compatibility. However, the efficient alkaline tin plating/stripping process has not been achieved due to high thermodynamic barrier and poor electrochemical kinetics. In this study, a highly reversible stannite-ion electrochemistry was demonstrated for the first time, leading to the development of a novel paradigm of high-energy Sn-based aqueous batteries. The alkaline tin anode exhibited low potential, high specific capacity, superb rate capability, and excellent cycling durability, which proves the feasibility of the alkaline Sn metal anode and suggests the potential of high-energy Sn-based aqueous batteries for safe, reliable, and affordable energy storage.

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.
