Summary: This study modified a zinc-aluminum layered double hydroxide conversion coating on galvanized steel with benzotriazole as an organic corrosion inhibitor. The changes in the modified coating were investigated through microstructural and elemental analysis as well as electrochemical experiments. Results showed that benzotriazole was partially intercalated into the layered double hydroxide structure, and the modified films exhibited a 4 times increase in impedance compared to the as-synthesized films.

Summary: Ethylene diamine-N,N'-disuccinate (EDDS) is successfully intercalated into layered double hydroxide (LDH) sheets, resulting in the hybrid assembly [Zn2Al(OH)6]+ [EDDS]4-0.25 2H2O (LDH-EDDS4-). The presence of functionalized LDH-EDDS4- significantly decreases the surface reactivity of carbon steel in a neutral and aerated sodium chloride solution. The synergy effect between Zn2+ cations and EDDS4- anions is highlighted, and SEM and visual observations confirm the efficiency of hybrid LDH-EDDS4- in protecting the carbon steel surface from corrosion.

Summary: A super-hydrophobic anti-corrosion film was prepared by in situ growth of LDHs on AZ31 magnesium alloy and modification with PFOTMS, providing better corrosion resistance. The micro/nano hierarchical surface morphology and optimal hydrophobicity of the film contribute to a high contact angle, which remains above 140 degrees even after immersion in NaCl solution for 6 days.

Summary: In order to increase the corrosion resistance of a sample, its electrical impedance must be increased by modifying elements such as resistance, capacitance, and inductance. Multilayer thin films with zigzag structures exhibit better corrosion protection than conventional multilayer thin films, with zigzag structure 2 showing the highest corrosion resistance. This is attributed to the high electrical impedance of the structure due to its reduced capacitance and higher electrical resistance.

Summary: This study achieved in-situ incorporation of layered double hydroxides (LDH) nanocontainers into plasma electrolytic oxidation (PEO) coatings on AZ91 Mg alloy. Fumarate was selected as the Mg corrosion inhibitor for exchange and intercalation into the nanocontainers, which were then incorporated into the coating. It was found that the presence of LDH nanocontainers increased the thickness and compactness of the coatings. The corrosion resistance of the coatings was greatly enhanced and stabilized by the loaded inhibitor and nanocontainers through ion-exchange when corrosion occurred.

Summary: Gold nanoparticles were deposited onto titania nanotubular layers using photocatalytic deposition and compared with composites prepared from gold colloidal solutions. The method of photodeposition affected the size, distribution, structure, and surface characteristics of the deposited gold nanoparticles. Photoreduction deposition resulted in higher activity in the oxygen electroreduction reaction compared to sol-modified electrodes, which can be attributed to the consolidation of the gold-TiO2 interface and the absence of ligands on the gold nanoparticles' surface.

The synthesis of LDHs was performed in different growth solutions. The results showed that it was difficult to form LDHs on silicate-based PEO coating, while hydrothermal treatments in Al3+ containing solution played an important role in corrosion resistance for phosphate and silicate-based PEO coatings.

Summary: This study investigated the use of commercial synthetic hydrotalcite as an adsorbent for removing fecal indicator bacteria from water. The results showed that hydrotalcite had the potential to remove coliforms and enterococci from water, and the removal efficiency increased with higher hydrotalcite concentration, longer contact time, and lower pH. However, the removal efficiency decreased at low incubation temperature, and hydrotalcite did not exhibit bactericidal activity. The findings suggest that hydrotalcite could be used in technologies for water treatment from bacterial contamination.

Summary: Metal corrosion causes significant damage to the economy, environment, and industry. Smart self-healing coatings have attracted attention for active corrosion protection. These coatings achieve self-healing through either intrinsic or extrinsic methods. Intrinsic self-healing coatings utilize reversible physical and chemical interactions between molecules, providing permanent self-healing effects. Extrinsic methods involve embedding micro/nanocontainers in the coatings, which can sense changes in the micro-environment and repair the coating's surface. This review summarizes the research progress of micro/nanocontainer-based stimuli-responsive self-healing coatings, exploring their different functions and applications.

Summary: Re-evaluation of conventional wastewater treatment processes is important for improving the quality of aquatic environment. Electrochemical Advanced Oxidation Processes (EAOPs) using Boron-doped diamond (BDD) technology show promising results in degrading and mineralizing water pollutants. This study uses systematic literature review and bibliometric analysis to assess the synergism between AO using BDD technology and other oxidation methods. The findings suggest that combining AO with add-ons or Fenton-based methods enhances degradation and mineralization efficiencies, and further research is needed for effective application in wastewater treatment facilities.

Summary: In this study, the electrochemical responses and activities towards oxygen reduction reactions (ORR) of carbon-fiber-reinforced polymers (CFRP), glassy carbon, and Highly Ordered Pyrolytic Graphite (HOPG) were evaluated and ranked. The ranking of their activities in supporting cathodic reactions that can lead to galvanic corrosion on coupling with metallic materials is as follows: CFRP > glassy carbon > HOPG. The differences in the electrochemical responses of these carbon surfaces to ORR are postulated to be due to differences in the proportions of edge sites present on each carbon surface.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries.
