Summary: Gas sensors based on In2O3 exhibited high sensitivity to methane when loaded with Pd. However, they also showed high cross-sensitive responses to NO2, CO, and ethanol. By adding a Pt-Al2O3 catalyst film filter, the sensors were able to selectively respond to methane even in the presence of interfering gases. The catalytic conversion of CO and ethanol to CO2 and H2O, as well as the blocking of nitrogen dioxide molecules on the surface of the catalyst film, contributed to the improved selectivity of the sensors.

Summary: Laser cladding was conducted using Cr7C3/Ni3Al alloyed powder and Cr3C2/Ni3Al mixed powder to prepare a Cr7C3 reinforced Ni3Al composite cladding layer. The microstructure and tribological properties of the cladding materials were studied, revealing that the alloyed powder cladding layer exhibited a microstructure mainly composed of Ni3Al, NiAl, and in-situ formed Cr7C3, while the mixed powder cladding layer contained Cr3C2. The alloyed powder cladding layer showed lower friction coefficient and wear loss compared to the mixed powder cladding layer, and was more friendly to its counterpart. The improved wear resistance of the alloyed powder cladding materials can be attributed to the homogeneous distribution of fine in-situ formed Cr7C3, effectively separating the friction pair.

Summary: This study investigates the influence of prestrain-induced dislocations on the formation of both coherent and incoherent precipitates in medium-entropy alloys (MEAs). The results show that prestrain increases the formation of incoherent precipitates and refines their size, while having little effect on the formation of coherent precipitates.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
