Summary: Insights were gained into the roles of geometry, size, and composition on MnS inclusion dissolution to initiate pits in 304L SS through a combination of operando and ex-situ electron microscopy, EDS, and atomistic modeling. It was found that the majority of MnS on the SS surface did not dissolve even after prolonged exposure, with only a small number causing an attack on the SS. Operando TEM during potentiodynamic polarization confirmed that MnS attack was followed by corrosion of the nearby SS substrate, and atomistic modeling suggested that elemental variations in surface composition may differentiate pitting initiation by sulfur species.

Summary: The parametric study identified specific conditions that lead to corrosion of mild steel in marginally sour environments, including temperature, H2S pH, solution pH, and sodium chloride concentration. Transmission electron microscopy revealed a porous layer containing mackinawite and magnetite, with corrosion initiating when the mackinawite layer broke down and exposing the steel surface to corrosive substances, leading to propagation of corrosion due to galvanic coupling.

Summary: The microstructural evolution and pitting performance of Cr-13 type martensitic stainless steel tempered at 500°C for different times were studied. Severe corrosion was observed when tempering was done within 2-24 hours, while passivation was recovered when tempering time was increased to 48 hours or longer. The research provides a new approach to optimizing the corrosion resistance of martensitic stainless steels through tempering time.

Summary: The study investigated the effect of Te concentration in molten FLiNaK salt on the corrosion and mechanical properties of 304 stainless steel. The corrosion depth of samples decreased with increasing Te concentration after 48 h immersion at 600 degrees Celsius. Additionally, the 1.0 wt% Te sample showed less reduction in mechanical properties compared to the 0.1 wt% Te sample. It is hypothesized that a protective Cr-oxide layer is formed beneath the Ni-Fe rich layer formed by selective leaching of Cr.

Summary: The pitting corrosion resistance of duplex stainless steel welds was investigated. It was found that pitting corrosion mainly occurs in the high-temperature heat-affected zone and is initiated by (Ti, Cr)N in the ferrite. Titanium-containing nitrides can precipitate in the heat-affected zone even with a low titanium content. The lack of a passive film on the (Ti, Cr)N surface also contributes to pitting corrosion initiation.

Summary: The effect of tellurium (Te) on the localised corrosion mechanism in 15-5PH stainless steel in a simulated marine environment was investigated. The addition of Te changed the composition and size of inclusions, impacting the corrosion behavior of the steel. Inclusions were found to have good electrical conductivity and were electrochemically dissolved. The presence of Te in the inclusions altered the localized corrosion mechanism, with the appropriate addition of Te improving the pitting potential and corrosion resistance of the steel.

Summary: Various methods based on impedance and nonlinear frequency response are evaluated for determining the state-of-health (SOH) of commercial lithium-ion cells. Frequency response-based measurements provide a spectral representation of the underlying physicochemical processes in the cell, giving evidence about its internal physical state. These methods can be carried out more rapidly and offer more efficiency in determining the SOH of aged lithium-ion cells.

Summary: Differentiation of a Li-ion battery cycling profile results in a pair of complementary measures, differential capacity and differential voltage, which are used to diagnose cell state and aging mechanisms. This article presents a fundamental theory of differential analysis from single electrode measurements to full cell data, considering cell balancing and degradation. The new approach uses a graphical heuristic to superimpose voltage and capacity data on a 2D representation of the cell state, harmonizing various complementary approaches from existing literature.

Summary: A physicochemical model of electrochemical potential distribution in a proton exchange membrane water electrolyser (PEMWE) stack is developed to understand the corrosive potential at the anode bipolar plate (BPP) and porous transport layer (PTL). The model predictions suggest that cheaper materials can be used instead of highly corrosion-resistant materials, which would significantly reduce the cost of green hydrogen.

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.
