Summary: EH40 steel's corrosion behavior in seawater enriched with Methanococcus maripaludis was investigated, showing initial inhibition of corrosion followed by eventual propagation. The presence of M. maripaludis promotes both anodic and cathodic reactions of EH40 steel, while the protective corrosion products film inhibits corrosion during early immersion stages. Pitting corrosion is closely related to uneven distribution of M. maripaludis biofilm on EH40 steel surface.

Summary: D-phenylalanine has been shown to prevent localized corrosion on Q235 carbon steel by inhibiting biofilm formation and altering biofilm structure when lactate is the main electron donor. When lactate and yeast extract are removed, D-Phe significantly reduces overall corrosion loss, likely due to its involvement in the Stickland reaction involving L-cysteine and bacteria-transformed L-phenylalanine.

Summary: The influence of Ca2+ on the growth mechanism of CO2 corrosion products was explored through weight loss, in situ electrochemical measurements, and analysis of corrosion products. The increase in Ca2+ concentration in the solution weakened the crystallinity of the product film, FexCa(1-x)CO(3), gradually transforming it into an amorphous structure. This resulted in reduced protectiveness and an elevated corrosion rate. Higher concentrations of Ca2+ led to unstable growth of FexCa1-_xCO3. At 10000 mg L-1 Ca2+, complex FexCa1_xCO(3) structures with varying Ca content were formed. A linear relation between Ca2+ concentration in the solution and the molar fraction of Ca in the film was also proposed.

Photolysis at the metal-ligand charge transfer band (MLCT) of the isomers released nitric oxide (NO) at different rates. We investigated endothelium-dependent vasodilation induced by cis-[Ru(bpy)2(4-pic)(NO2-kappa N)]+ and cis-[Ru (bpy)2(4-pic)(NO2-kappa O)]+ in aortic rings and found that the release of NO was three times faster for cis-[Ru(bpy)2(NO2-kappa O)Ln-](n-1) compared to cis-[Ru(bpy)2(NO2-kappa N)Ln-](n-1).

Summary: This article critically evaluates the literature on the use of the Langmuir isotherm in inhibitor research. The validity of the Langmuir isotherm has been challenged, particularly by Walczak et al. (2019), leading to its rejection by some researchers. Imposing limitations on the Langmuir isotherm would affect heterogeneous kinetics, impedance interpretation, and other transient techniques. This discussion paper provides a more in-depth analysis of these aspects.

Summary: This research examined the corrosion inhibition effect of three extracts from soybean meal and a soybean protein commercial sample on mild steel, using mass loss tests, electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization (PDP). The soybean meal extracts' anti-corrosive properties were investigated by normalizing the peptide/protein amount. The inhibitors were characterized chemically and the surface of mild steel was studied by scanning electron microscopy (SEM). The results showed that all inhibitors showed the same inhibition efficiency when the normalization in peptide/protein amount was performed, indicating that proteins/peptides are responsible for inhibiting corrosion. For example, at 100 mg L-1 in protein content, the inhibition efficiency was 84% and 82% from EIS and PDP results, and 89% and 93-94% after 2 and 24 h immersion time, respectively, from mass loss measurements. Polarization curves indicated that all inhibitors behave as a mixed-type inhibitor, particularly for the cathodic branch. SEM results suggested that all extracts promoted a protective action against corrosion of the mild steel in H2SO4 solution.

Summary: High porosity Co-Al-Fe intermetallics with 3D-microstructures were successfully synthesized in one step via a thermal explosion reaction. The link between pore structure and permeability was investigated using 3D-XRM technology. The corrosion resistance of the samples with different Fe contents was studied at 900 degrees C under an oxygen/sulphur atmosphere for up to 120 h. The results showed that the samples maintained stable pore structure and intact internal matrices, attributed to the formation of a thin protective layer on the surface. In addition, inward diffusion of S resulted in the formation of FeS nodules.

Summary: In this study, an environmentally friendly volatile corrosion inhibitor, lysine salts (LA), was prepared between graphene oxide (GO) layers using an in situ intercalation technique. The corrosion inhibition effect of LA was evaluated, and it was found that LA-GO2 achieved a 99.3% corrosion inhibition efficiency after composition optimization. The inhibition of the electrochemical anodic process on the surface of mild steel was the main reason for the high corrosion inhibition efficiency of LA-GO2. The properties of the surface film on the corroded steel were also characterized in detail to understand the corrosion inhibition mechanism of LA-GO2.

Summary: This study presents a new approach to studying the mechanism of filiform corrosion in organic coated steel using the scanning vibrating electrode technique (SVET) and micropotentiometry (potentiometric SECM). The electrochemical activity under the coating was evaluated by mapping the ionic current densities coming from artificial defects made in specific locations of the filament. Antimony tips were also used to investigate the pH changes associated with different corrosion reactions at the metal-paint interface. Local pH levels along the filament in the anodic and cathodic regions were determined.
