Summary: Copper and its alloys are widely used in marine environments, and anisotropic corrosion affects the corrosion kinetics of copper. This paper studied the corrosion behavior of Cu(100) and Cu(111) using electrochemical impedance spectroscopy (EIS) after OCP tests. The results showed that Cu(100) exhibited better corrosion resistance. The corrosion mechanism of Cu(100)/Cu(111) in different stages was proposed based on the equivalent electrical circuit (EEC) diagrams.

Summary: Advancements in energy storage, photocatalysis, and sensors have generated large amounts of electrochemical impedance (EIS) data. Interpreting this data is challenging, but recent progress in machine learning (ML) models for EIS classification has been made. However, most models lack physical descriptor representation. In this study, variational autoencoders (VAE) were applied to EIS data analysis, achieving accurate classification, parameter prediction, and physical descriptor visualization.

Summary: An identification algorithm based on gene expression programming is introduced to support researchers in deciding which equivalent electrical circuit to use for analyzing electrochemical impedance spectroscopy measurements. This algorithm enhances the interpretability of resulting circuits by removing redundant components and departing from an initial population of widely applied circuits, enabling quick identification of known circuits capable of modeling the data.

Summary: In PEM fuel cells, oxygen diffusion is influenced by both the gas diffusion layer and the cathode catalyst layer. Experimental data shows that the low-frequency diffusion impedance is mainly related to the gas diffusion layer, while the high-frequency impedance is primarily affected by the ionomer film in the cathode catalyst layer. Therefore, the appropriate equivalent electrical circuit is the series connection of the Kulikovsky diffusion impedance and the ORR kinetics circuit.

Summary: This study aims to improve the performance of solid-state supercapacitors (SSCs) by simulating their impedance using a defined equivalent circuit (EC) model. Two models, a mathematical model and a physicochemical model, were used and the impedance was measured using electrochemical impedance spectroscopy (EIS). The physicochemical model showed higher approximation ability due to its more complex circuit design, but also required more modeling and optimization effort.

Summary: In this work, the damage degree of freeze-thaw of engineered cementitious composites (ECC) was assessed by electrochemical impedance spectroscopy (EIS) technique. The results showed that the EIS behavior of ECC varied with the freeze-thaw cycles, with the diameter of the Nyquist curve in high frequency gradually reduced and the volume resistance decreasing. A simplified microstructure and conductive paths were used to describe the freeze-thaw damage mechanism of ECC, and an equivalent circuit model of ECC exposed to freeze-thaw cycles was proposed.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
