Summary: This study investigated the corrosion behavior of brass in various cooling water conditions and TiO2 nanofluid, finding that the presence of SDBS as a dispersing agent led to the formation of a protective adsorption film on the brass surface in SCW-SDBS medium, reducing corrosion rate. However, the competitive adsorption of TiO2 nanoparticles and SDBS anions in SCW-SDBS-TiO2 nanofluid hindered the formation of the protective SDBS adsorption film on the brass surface, leading to reduced corrosion inhibition performance.

Summary: The use of nanofluids as vehicle coolant can improve heat exchange efficiency, but it is important to understand their corrosiveness to metals. The study investigated the corrosion behavior of aluminum alloy in different coolant solutions and found that SDBS exhibited good corrosion inhibition effect on aluminum alloy, forming a compact passivation film on the alloy surface. However, in the presence of both SDBS and Al2O3 nanoparticles, the corrosion inhibition effect of SDBS was weakened due to electrostatic attraction between the nanoparticles and SDBS, reducing the protective effect on the metal surface.

Summary: The critical micellar concentration (cmc) is a fundamental property of surfactant solutions, which can be determined using a concentration model and equations for different surfactant properties. This modular concept allows for systematic and unambiguous determination of cmc, and can be applied to study both surfactants as well as non-surfactant systems.

Summary: Surfactants are widely used in various industries such as household cleaning, personal care, and cosmetics. However, most of the surfactants currently in use are derived from fossil fuels and are environmentally unfriendly and toxic. Therefore, there is a need for greener alternatives. The determination of the critical micelle concentration of surfactants is crucial for their development as analytical tools and commercial materials. A fast and cost-effective method using dried drop coffee ring image analysis is proposed for determining the surfactant critical micelle concentration.

Summary: When two or more surfactants are mixed, the performance of the mixed system is improved compared to a single surfactant solution. The Markov chain model can analyze the critical micelle concentration (CMC) of mixed micelles and yield similar results to the regular solution theory. This study tested two hypotheses and derived equations to describe the data of CMC and partition coefficient well.

Active sites appeared on the surface of 2205 DSS at a lower Cl- concentration compared to 2507 DSS, resulting in higher surface roughness and weight loss.2507 DSS exhibited lower degree of general corrosion and less surface corrosion products.

Summary: The corrosion resistance of both the base metal (BM) and the weld metal (WM) of 2205 duplex stainless steel (DSS) decreases with increasing immersion time in an ash/water suspension. After 4 hours of immersion, active sites appear on the WM surface, indicating the beginning of pitting corrosion, while it takes 8 hours for active sites to appear on the BM surface. The pitting corrosion resistance of the 2205 DSS base metal is better than that of the weld metal with a high proportion of dendritic ferrite in the metallographic structure.

Summary: The effect of ZnO nanoparticles on sulfate-reducing bacteria and their adhesion behaviour on stainless-steel surfaces was investigated. The concentration of ZnO NPs and light treatment greatly influenced the antibacterial performance. Low concentration of ZnO NPs promoted SRB growth and biofilm adhesion, while higher concentrations exhibited antibacterial effects. Under visible light irradiation, ZnO NPs showed antibacterial performance at all concentrations, and the efficacy increased with concentration. Light treatment stimulated ZnO NPs to generate reactive oxygen species, which exhibited good antibacterial properties. The adhesion amount of SRB on the stainless-steel surface was inversely proportional to the antibacterial efficiency of ZnO NPs.

Summary: The scaling on the cathode surface increased as the polarization potential shifted negatively, while the scale inhibition performance of PBTCA was enhanced with increased concentration. However, lower concentrations of PBTCA promoted scaling on the cathode surface at lower polarization potentials. The CaCO3 crystals formed in the blank solution were mainly calcite, while those in the solution containing PBTCA were all calcite due to increased Ca2+ concentration and pH near the cathode surface.

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: The oxidation behavior of FeCrNi medium entropy alloy was investigated through experimental observations and density functional theory (DFT) calculations. The study found that at 900 degrees C, the alloy forms a desirable and continuous oxide layer, while at 1000 degrees C, the oxide layer becomes discontinuous with penetration of oxide. These observations highlight the significant role of phase structure in promoting the formation of protective oxide scales and influencing oxidation resistance.

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.

Summary: This work explores the correlation between electrolyte transport properties and the variation of pigment volume concentration (PVC) in organic coatings. 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.
