Summary: The initial corrosion behavior and mechanism of 7B04 aluminum alloy under acid immersion and salt spray environments were studied using various characterization methods. Pitting corrosion occurred in the initial corrosion stage, and the potential difference between second phase particles was identified as the main cause. The main components of the corrosion products were Al2O3, Al(OH)(3), and AlCl3, with a higher generation rate under the salt spray environment. The Volta potential gradually shifted in a positive direction, indicating an inhibitory effect of corrosion products on corrosion. The corrosion current density was significantly lower for the salt spray sample, suggesting that a thicker corrosion product layer provided stronger inhibition of corrosion reaction.

Summary: This study investigated the initial corrosion behavior of Fe-Mn-Al-C-Ni lightweight steels with different B2-phase grain sizes in 3.5 wt.% NaCl solution. Quasi-in-situ short-period immersion tests and electrochemical experiments revealed the immersion corrosion process of Fe-Mn-Al-C-Ni mild steel and the selective corrosion characteristics of the alloy surface. Results showed that the grain size of granular B2 phase was significantly reduced compared to the striped B2 phase, and the diffuse distribution of granular B2 phase in the matrix led to a more uniform corrosion behavior and improved corrosion resistance of the alloy.

Summary: In this study, the microscopic adsorption mechanism of PAM on kaolinite surface in the presence of Ca2+ was investigated using DFT. The adsorption of PAM on kaolinite (001) surface was found to be dominated by three strong hydrogen bonds, while non-bonding interactions were observed on the kaolinite (00-1) surface. The presence of Ca2+ promoted the adsorption of PAM on the kaolinite (001) surface, but inhibited adsorption on the kaolinite (00-1) surface.

Summary: Organic carbonyl compounds as electrode materials have promising potential for next-generation aqueous rechargeable batteries. However, their poor cycling performance, caused by high solubility of discharge products, has limited their broader application. In this study, we developed a strategy to enhance the cyclability of aqueous zinc-organic batteries by modifying the structure of perylene-3,4,9,10-tetracarboxylic dianhydride. The modified cathode showed excellent discharge capacity and long cycling stability, with a reversible co-insertion mechanism of Zn2+/H+ at the carbonyl site.

Summary: This study proposes magnesium-doped layered manganese dioxide (Mg-MnO2) as cathode materials for aqueous zinc-ion batteries (ZIBs) to improve their performance. Mg-MnO2 with a larger specific surface area provides more electroactive sites and enhances the capacity of ZIBs. The electrical conductivity and ion diffusion coefficients of Mg-MnO2 are also improved by doping cations and oxygen vacancies in the MnO2 lattices. The assembled Zn//Mg-MnO2 battery exhibits a high specific capacity and reversible redox reaction between Zn2+ and MnOOH, promoting capacity and stability.

Summary: All-inorganic metal halide perovskites (MHPs) have great potential for flexible electronics due to their excellent photo-physical properties and low-cost fabrication. However, their suboptimal quantum yield and stability have hindered their diverse wearable applications. A water evaporation crystallization strategy is proposed to prepare salt-shelled metal halide solids, which exhibit narrow photoluminescence and high quantum yield. These materials can be used in waterborne transparency inks and flexible photoluminescent films, as well as in high-performance positive friction materials for triboelectric nanogenerators. Furthermore, a wearable photoluminescent sensor with voltage response range and quick response time is constructed. These metal halides open up possibilities for lightweight and multifunctional wearable electronics.

Summary: In this study, an electrostatic field layer (EFL) was established using an electrolyte additive of cobalt tetraaminophthalocyanine (Co(TAPC)) to address the instability issue of the Zn metal/electrolyte interface, parasitic reactions, and dendritic growth, resulting in low Coulombic efficiency (CE) and poor cycle life. The Co(TAPC) with a planar and large conjugated ring structure could preferentially absorb on the Zn metal anode to form a zincophilic EFL, which prevents direct contact of Zn and water, suppresses side reactions, promotes desolvation and Zn2+ diffusion kinetics, and balances the space electric field, thereby enabling high-rate and dendrite-free Zn deposition.

Summary: This study investigates the influence of He-V complexes on H behaviors on different W surfaces using DFT calculations. The results show that H dissolution is most difficult but H trapping is easiest on the W (110) surface, while the opposite is true on the W (111) surface. Moreover, the presence of He-V complexes increases the difficulty of H diffusion from bulk to surface and desorption.

Summary: This study proposes a probabilistic and diffusion-based model to describe the co-deposition of multiple hydrogen isotopes with slowly grown metal layers. The model calculates the relative concentrations of different hydrogen isotopes in the co-deposited metal layers. It is found that if hydrogen isotopes have different detrapping energies, only the isotope with the highest detrapping energy shows a monotonic decrease in concentration with deposition temperature. Furthermore, the study evaluates the uncertainty of tritium concentration in the co-deposited layer based on the uncertainty in detrapping energy of tritium and deuterium, predicting a >10% tritium concentration uncertainty for a 0.01 eV difference.
