Summary: A ternary mixed metal oxide coating of Sn-Ru-CoOx was prepared by ultrasonic treatment, and the effect of ultrasound on the electrochemical performance and corrosion resistance of the electrode was investigated. Results showed that the ultrasonically treated electrode demonstrated a more uniform oxide dispersion, smaller grain growth, and more compact surface morphology compared to the untreated anode. Additionally, the ultrasonically treated coating exhibited the best electrocatalytic performance with a 15 mV reduction in chlorine evolution potential. The ultrasonically pretreated anode also had a longer service life of 160 hours, 46 hours longer than the untreated anode.

Summary: This study proposes a dependable approach for the selective and sensitive identification of zinc, cadmium and lead in different sample matrices using an over-oxidized poly(xylenol blue) film glassy carbon electrode coated with bismuth (Bi/PXBov.ox/GCE). The best conditions for determining these elements were found to be a 0.1 mol L-1 acetate buffer solution as supporting electrolyte (pH 4.5), -1.5 V accumulation potential, and 180 s accumulation duration. Under these conditions, the detection limits of Zn(II), Cd(II) and Pb(II) were 3.20 μg L-1, 0.21 μg L-1 and 1.98 μg L-1, respectively. Moreover, this novel, cheap and easy-to-prepare Bi/PXBov.ox/GCE was successfully used for the analysis of Zn(II), Cd(II) and Pb(II) in lipstick samples, with consistent results compared to inductively coupled plasma mass spectrometry.

Summary: This study investigates the electrodeposition of PbO2 on a Ti substrate from nitrate bath to serve as the oxygen evolution anode. The effects of predeposition of alpha-PbO2 interlayer and the use of additives in the electrolyte were studied. Characterization of the coatings was done by X-ray diffractometry and SEM techniques. The electrochemical properties were evaluated and the most favorable performance was achieved with a Ti/alpha-PbO2/beta-PbO2 electrode produced in a nitrate solution containing NaF, Cu(NO3)2, and SDS, showing a significant increase in i(max) and a notable decrease in oxygen evolution potential.

Summary: This article analyzes the electrode performance of misfit-layered calcium cobaltite as a cathode and anode for solid oxide fuel cell and solid oxide electrolysis cell, respectively, using electrochemical impedance spectroscopy. The addition of Ce0.8Gd0.2O2-delta as a composite electrode phase significantly improves the electrochemical processes and reduces the polarization resistance. Short-term stability testing demonstrates that the composite material shows stable current density and no observable microstructure delamination at 700°C.

Summary: In this study, a new method for producing ultrathin Co3O4 nanoflakes on a nickel foam substrate is presented, resulting in a Co3O4@NF electrode with excellent catalytic performance. The electrode has an intrinsic cross-linked structure, strong affinity, good conductivity, and a large active surface area. As an additive-free electrode, it demonstrates low overpotential, a small Tafel slope, and durable stability in the oxygen evolution reaction. Additionally, when used with Pt@NF as the cathode and Co3O4@NF as the anode, the electrolyzer shows high current density and improved long-term stability.

Summary: In this study, the individual gas bubble nucleation and dynamics on nanoscale electrodes were investigated using scanning electrochemical cell microscopy (SECCM). The nanostructured catalyst surface showed significantly less supersaturation for gas bubble nucleation and a notable increase of bubble detachment compared to its flat counterpart. The results suggest that deliberate microstructure design on a catalyst surface is a promising strategy for improving electrocatalytic gas evolution in terms of both bubble nucleation and elimination.

Summary: The equiaxed zone with low hardness in fusion welded Zr-containing aluminum alloys is a significant threat to the structural integrity of welded components. High-angle grain boundaries in the equiaxed zone are decorated with a network of brittle omega (Al7Cu2Fe) and S (Al2CuMg) phases, leading to intergranular failure through void nucleation and strain localization. Time-lapse X-ray computed tomography and in situ scanning electron microscopy show that these phases contribute to failure at low plasticity levels.

Summary: In this study, the microstructure of AA6082 alloy under different manufacturing processes was investigated using three-dimensional visualization. The results showed that the formation of supersaturated solute front at the α-Al solid-liquid interface is the key condition for the formation of Fe-bearing intermetallics and Mg2Si phase. Grain refinement processing leads to severe interconnectivity of Fe-bearing α-intermetallics, while intensive melt shearing process can more evenly distribute and refine the intermetallics, thereby improving the properties of the alloy.

Summary: High-performance Nb-doped TiO2 thick films with enhanced thermoelectric performance are fabricated using facile and scalable screen-printing techniques. The films exhibit different defect structures, including crystallographic shear (CS) structures, twin boundaries, and Al-segregated CS structures, which contain abundant oxygen vacancies and enable energy-filtering effects. These CS structures contribute to the simultaneous enhancement of electrical conductivity and Seebeck coefficients, resulting in the highest power factor observed in TiO2-based TE films at elevated temperatures. The microstructure modification strategy provides a novel route for atomic-level defect engineering.

Summary: Five different heat treatments applied to AA7075 aluminum alloy resulted in distinct localized corrosion behaviors in 5 wt% NaCl solution. Certain treatments exhibited higher intergranular corrosion (IGC) susceptibility due to anodic nature of grain boundaries (GBs) caused by Cu depletion in the precipitate free zones (PFZs) along GBs. Neither Cu-enrichment nor an increase in intervals between η-phase grain boundary precipitates (GBPs) improved IGC resistance. Open circuit (OCP) and galvanostatic (GL) tests were able to differentiate corrosion behaviors, suggesting the potential use of GL testing as a faster method for predicting localized corrosion behaviors.
