Summary: This study investigated the regulatory mechanisms of autoinducer-2 (AI-2) on Q235 carbon steel corrosion caused by Desulfovibrio sp. Huiquan2017 in cultures with extremely deficient organic electron donor. It was found that AI-2 promoted bacterial chemotaxis to Fe2+ and enhanced biofilm formation, leading to increased weight loss and aggravated selective phase corrosion.

Summary: The crevice corrosion of X70 steel varies in different pH solutions, with pH=2 and pH=12 solutions promoting crevice corrosion while pH=6.8 solution prevents it. The increase of pH and Cl- inside crevice contribute to crevice corrosion in pH=2 solution, while the decrease of pH and increase of Cl- inside crevice lead to crevice corrosion in pH=12 solution.

Summary: This study focused on obtaining a black coating on a low carbon steel surface using three different solutions, revealing that the protective layer obtained through 15 minutes immersion at boiling point was dense and adherent, while longer or shorter immersion times resulted in non-uniform layers with porosities. The use of a cold solution led to an uneven layer and reduced corrosion resistance. The morphology, color, defects, composition, and corrosion resistance of the protective layer were evaluated through various microscopic and spectroscopic techniques.

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 study explores the scale formation behavior of N80 steel in CO2 environments at different temperatures and immersion times. It is found that temperature and immersion time significantly influence the electrochemical behavior, as a result of different scales formed on the steel surface.

Summary: In H2O-saturated supercritical CO2, H2S promotes the formation of a protective FeS layer, but increasing temperature or adding O-2 can destroy the integrity of this layer and enhance corrosion significantly. The corrosion is likely controlled by gas chemical reactions instead of electrochemical reactions, and the sulfide stress cracking susceptibility of strained pipeline steels is lower than expected.

Summary: Carbon-based materials have attracted great interest for their unique properties and breakthroughs in clean energy applications. However, their low selectivity and poor conductivity have hindered their commercialization. To improve hydrogen production efficiency, researchers are exploring ways to increase surface area, create interconnected porous channels, and enhance stability of carbon-based materials. This review summarizes the structural advantages and performance improvements of various porous carbon-based materials and evaluates the performance of hydrogen production methods. The role of active sites in promoting charge transport, electrical conductivity, and stability during hydrogen production is discussed. Challenges and future directions for the development of high-efficiency hydrogen 3D porous carbon-based materials are also discussed.

Summary: This study investigated the inhibition of corrosion of deposit-covered pipeline steel in seawater containing CO2 in the presence of Pseudomonas stutzeri. The results showed that the presence of deposits led to a decline in the corrosion rates of the steel, and the corrosion rates were slower when P. stutzeri was present. The corrosion inhibition efficiency of P. stutzeri was reduced in the presence of deposits, likely due to the lowered biological activity.

Summary: In this study, a highly efficient electrocatalyst was developed by anchoring Co nanoparticles on N-doped porous carbon material. The catalyst showed comparable catalytic activity with commercial 20% Pt/C for the oxygen reduction reaction. A home-made Zn-air battery exhibited excellent performance with a stable discharge voltage for up to 9 days. The enhanced performance of the electrocatalyst was attributed to its high content of pyridinic-N and graphitic-N species, extra Co loading, and porous structure.

Summary: Readily synthesized and highly antibacterial polyhexamethylene guanidine molybdate (PHMG-MoO4) can significantly improve the resistance of epoxy coating to sulfate reducing bacteria (SRB) biofilm as a filler. In SRB inoculated medium, no SRB biofilm formed on PHMG-MoO4/epoxy coating after 120 days, and the corrosion current density of the epoxy coating painted carbon steel decreased by 99.0% after addition of PHMG-MoO4 in the coating. There were also fewer fouling organisms on PHMG-MoO4/epoxy coating after 4 months of immersion in the actual seawater.

Summary: Inspired by the self-cleaning properties of crustaceans, chitosan (CS)/Poly (vinyl alcohol) (PVA) hydrogels were prepared and their anti-biofouling and salt tolerance were investigated. The CS/PVA hydrogels showed controllable triggering at low pH and self-adjustment for enhanced anti-biofouling performance. Their hydration was enhanced in seawater due to their low salt sensitivity and super hydrophilicity. Field tests confirmed the excellent anti-biofouling ability of CS/PVA hydrogels after 6 months of testing.

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.

An odd random phase electrochemical impedance spectroscopy (ORP-EIS) approach is used to analyze the diffusion of ions independent from water uptake. The results show that a higher PVC leads to a more homogeneous coating structure, resulting in faster diffusion of ions and enhanced water uptake.

Summary: The relationship between configurational entropy and lattice distortion in novel rare earth monosilicates was investigated, and the effect of configurational entropy on their properties was studied. The results showed that lattice distortion increased with the increase of configurational entropy, but a highly symmetrical crystal structure was formed when the configurational entropy was large enough, inhibiting the lattice distortion.
