Understanding elemental corrosion currents and visualizing corroding topographies provide a detailed insight into corrosion mechanisms at the nano-scale. Here, we develop a strategy to understand the elemental composition, corrosion resistivity and local stability of passive materials. Specifically, we utilize a pulse…

Developing scalable and environmentally benign anticorrosion coatings is critical for protecting steel infrastructure in chloride-rich environments. Here, a nacre-inspired multilayer epoxy coating reinforced with four MXene systems is investigated. This architecture forms a dense lamellar network that increases…

Corrosion of materials not only accounts for about 3 to 4% of economic losses in GDP in an industrial nation, but it also contributes significantly to greenhouse emissions and climate change because material production is one of the largest greenhouse emitters. According to a recent research study [1], steel production…

One hour of immersion is enough to distinguishing different performances depending on the system (Fig. 10a and b). It is noticeable the low impedance values that were observed for samples with rGO 0.1 wt% and 0.15 wt%. However, considering the behaviour observed in the free film experiments, the low impedance values…

Desulfovibrio vulgaris and Desulfovibrio ferrophilus were previously proposed to have distinct iron corrosion mechanisms because D. ferrophilus corroded faster. However, the chloride concentration in the D. ferrophilus ‘marine’ medium was much higher than in the D. vulgaris ‘freshwater’ medium. D. vulgaris corrosion…

Microbially-induced corrosion (MIC) has been well-studied in the context of damage to iron-bearing infrastructure, where microbes can solubilize solid elemental iron using redox-active metabolites such as phenazines. Whether such pathways can solubilize economically-critical cobalt remains poorly understood. We…
