Summary: The study aimed to synthesize and explore the inhibitory effects of three morpholinium cationic surfactants on carbon steel corrosion in petroleum wells formation water containing 3 M HCl solution at different temperatures. The synthesized compounds were characterized by FTIR and HNMR analysis, with inhibition efficiencies reaching up to 93.1%. Temperature effects on corrosion behavior were studied and the Villamil adsorption isotherm was found to be the most suitable model. Additionally, the biocidal activity and surface morphology improvements of the surfactants were investigated, showing promising results in corrosion inhibition.

Summary: In this study, N80 carbon steel and 26Cr3Mo chromium steel pipelines were tested for sulfate-reducing bacterium (SRB) microbiologically influenced corrosion (MIC) mitigation using a THPS-based commercial biocide and a synthetic cyclic peptide as a biocide enhancer. The results showed that the addition of 200 nM peptide reduced the dosage of the THPS biocide by nearly half and exhibited significant inhibition of microbial biofilms within 1 hour.

Summary: A novel porphyrin derivative (P1) and its brominated analog (P2) were successfully synthesized and their corrosion inhibition properties on stainless steel 304 (SS304) were studied. The protection efficiency increased with increasing concentration of the compounds and Langmuir's isotherm provided the best fit for describing the adsorption capabilities on SS304 surface.

Summary: The research investigated the effects of temperature and ultraviolet radiation on the corrosion behavior of carbon steel in a high humidity atmospheric environment. Results showed that the corrosion rate of carbon steel in high humidity marine atmosphere is significantly influenced by environmental temperature, with weight loss rate increasing as temperature rises. Additionally, both the composition and morphology of the rust layer changed with increasing temperature, and UV illumination had a greater impact on carbon steel at higher temperatures.

Summary: This study prepared and tested three new phospho-surfactants as corrosion inhibitors for carbon steel in aggressive HCl medium. The results showed that the surfactant tail length had a significant impact on the corrosion protection process, with longer chain surfactants exhibiting higher inhibition efficiency. The highest inhibition efficiency was achieved at 70 degrees C, following Langmuir adsorption isotherm, with ZGH surfactant showing the highest efficiency compared to other candidates.

Summary: In this study, we investigated the corrosion-inhibition performance of PMBMH as an inhibitor for mild steel in hydrochloric acid solution. The results showed that PMBMH effectively reduced the corrosion rate and increased the inhibitory efficacy. Experimental and theoretical findings indicated that PMBMH formed a protective adsorption layer on the mild-steel surface, contributing to the inhibition of corrosion.

Summary: Characterising the corrosion behaviour of pipeline steels in impurity-containing dense phase CO2 is crucial for cost-effective carbon capture and storage projects. Experimental studies have been conducted to predict and control corrosion using various testing methods. However, the reliability and reproducibility of published literature on corrosion rates are lacking due to challenges in controlling test parameters, highlighting the urgent need for a standard test method.

Summary: The corrosion inhibition effect and synergistic mechanism of a novel imidazoline derivative and benzimidazole in simulated concrete solution were studied. It was found that when the concentrations of the two inhibitors were 0.1 g/L and 0.9 g/L respectively, they showed the best synergistic effect, forming a protective film to inhibit the corrosion of carbon steel. Molecular dynamics simulations confirmed the stable adsorption of the composite inhibitor on the surface of carbon steel, with the highest stability at the above concentrations.
