Summary: Different hierarchical porous In2O3 nanostructures were synthesized, and their gas sensing properties towards methane were studied. The results showed that the sensor based on In2O3 obtained after 48-hour hydrothermal reaction had a response of about 10.4 to 500 ppm methane, exhibiting good reproducibility and exponential linear relationship. This study provides a feasible strategy for enhancing the gas sensitivity of In2O3 towards methane at low temperatures.

Summary: Effective detection of toxic and hazardous gases is crucial for ensuring human safety, and high-performance metal oxide-based gas sensors play an important role in achieving this goal. In2O3 is a widely used n-type metal oxide in gas sensors, and various In2O3 nanostructures have been synthesized for detecting small gas molecules. In this review, we provide a brief summary of current research on In2O3-based gas sensors. We discuss methods for synthesizing In2O3 nanostructures with various morphologies, and mainly review the sensing behaviors of these structures in order to better understand their potential in gas sensors. Additionally, the sensing mechanism of In2O3 nanostructures is discussed. Our review further indicates that In2O3-based nanomaterials hold great promise for assembling high-performance gas sensors.

Summary: Uniformly distributed In2O3 nanoparticle modified reduced graphene oxide sheets (In2O3/rGO) were synthesized via a normal-pressure microwave-assisted method with an in situ growth process. In the In2O3/rGO composites, In2O3 nanoparticles with sizes ranging from 3 to 26 nm are evenly fixed on rGO surfaces. In2O3/rGO sensors exhibit high sensitivity, rapid response and recovery, and high selectivity toward 1-50 ppm NO gas at 150 degrees C. The mass ratio of indium nitrate to GO dramatically influences the NO-sensing properties of In2O3/rGO composites, and the 20-In2O3/rGO sensor shows the highest response at the optimal operating temperature of 150 degrees C. Compared with the In2O3 sensor, the 20-In2O3/rGO sensor presents greatly improved gas-sensing properties, including higher response, lower optimal operating temperature, and better selectivity toward NO gas. The response of the 20-In2O3/rGO sensor toward 50 ppm NO at 150 degrees C is 30.6, 6 times higher than that of the In2O3 sensor. The enhanced NO-sensing properties of the In2O3/rGO nanocomposite could be attributed to the synergistic effect of In2O3 particles and rGO sheets.

Summary: In this study, a method of applying KF water-in-salt electrolyte in Cu-Zn battery was proposed, and a battery system based on the shuttle of fluoride-ion was constructed. Due to the new anode conversion mechanism, the discharge platform was improved to 1.9 V and the battery worked steadily for 1600 cycles. The battery takes advantage of the high conversion voltage of metal fluoride, while retaining the characteristics of Cu-Zn batteries such as low price and environmental friendliness. This work not only avoids the generation of zinc dendrites, but also provides a new strategy to make Cu-Zn battery rechargeable.

Summary: Incorporation of alkali metal ions into Ag nanoparticles dispersed on SBA-15 silica can enhance the catalytic activity for hydrogenation of dimethyl oxalate to methyl glycolate. Specifically, 5Ag(1)-Li-0.05/SBA-15 shows superior thermal stability and can double the MG yield compared to pristine 5Ag/SBA-15 under identical conditions. The cationic charge of alkali metal ions plays a role in maintaining dispersion and modulating the surface valence of Ag NPs.

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.
