Summary: Electrochromic (EC) batteries have great potential in applications such as smart windows and wearable electronics. However, the lack of stable electrolyte and matching EC electrodes remains a challenge for achieving high working voltage window and energy density. In this study, a highly transparent ion-conducting film (ICF) was used to develop a rechargeable EC battery. The ICF exhibited high optical transparency and ionic conductivity. An electrochromic battery (ICF-ECB) was fabricated using the ICF, with Li4Ti5O12 (LTO) and LiMn2O4 (LMO) as the EC layer and counter electrode, respectively. The ICF-ECB showed high energy storage performance, cycling stability, and a reversible color transition between discharge and charged states, providing real-time information on the energy level and work status of the device.

Summary: This work introduces a highly efficient and durable catalyst, MoOx nanoclusters decorated on spinel-type porous metal oxide nanosheets, for aerobic oxidative desulfurization reactions. The electronic structure of the MoOx nanoclusters can be modulated by the metal oxide carriers, with Mo(V) species identified as the active center. The catalyst MoOx/CuCo2O4, with air as the oxidant source under atmospheric pressure, achieves the aerobic transformation of dibenzothiophene at 90°C with a turnover frequency of 16.2 h-1 and shows no performance attenuation or structural deformation in six successive reuses.

Summary: CuMn samples with different weight percentages of CuO were synthesized by mechanochemical route. The catalytic activity of the samples in CO-PROX was determined in the temperature range of 40-250°C. The formation of spinel phase enhanced the CO adsorption active sites and modified the redox properties. The incorporation of copper into manganese oxide modified the catalytic activity and structural properties. The 5CuMn catalyst with the highest BET area exhibited excellent CO conversion and selectivity, as well as significant resistance to water.

Summary: In this study, MnO2 nanorods coated tea bag filter paper were developed as a self-standing, bendable, and disposable electrochemical probe for sensitive and selective H2O2 detection. By addressing challenges in H2O2 sensing and utilizing core@shell architecture with MoS2, the MnS@MoS2/TBFP probe showed low detection limit, excellent sensitivity, and wide linear range for H2O2 detection. The non-enzymatic H2O2 detection performances of MnS/MoS2/TBFP were found to be selective, decisive, repeatable, and stable, making them promising for practical applications.

Summary: This study investigates the plastic strain distribution of cold spray Cu powders and coatings using electron backscatter diffraction (EBSD) analysis. It is found that more dynamic recrystallization and plastic strain release occur in the as-sprayed EP and GA coatings compared to the WA coating. The influence of recrystallization of twin grains in the GA coating on the ductility of the coating is discussed. The static recrystallization in the postannealing treatment is more prominent in the EP and GA coatings, supporting differences in dynamic recrystallization among the cold-sprayed coatings determined through EBSD analysis. The thermal conductivity of cold-sprayed Cu coatings is affected by recrystallization and strain release.

Summary: When cold spraying is performed at a velocity equivalent to or greater than a material-dependent critical velocity, powders undergo plastic deformation and localized heating, leading to metallurgical bonding and/or mechanical interlocking. This study examined the characteristics of Cu feedstocks and their influence on the bonding strength of cold-sprayed Cu coatings. The results showed that annealing released plastic microstrains in Cu powders, and feedstock properties affected the resulting coating's ductility and hardness.
