Summary: The review discusses the favoured design concept of permanent disposal of high level nuclear waste in containers and considers the corrosion processes that can affect these packages. It demonstrates the methodology used to calculate corrosion depth in a Canadian geological repository environment and suggests areas for future study. Various corrosion sub-allowances are considered, and the expected depth of corrosion over time is evaluated for a specific site condition.

Summary: This study investigates the effects of gamma irradiation on CuO NPs@PVP/PEO nanocomposite and characterizes the changes in structural, optical, and electrical properties. The research shows that gamma radiation leads to structural rearrangements in the polymeric, influences the surface Plasmon resonance of CuO NPs, and improves the optical parameter values. Additionally, the dielectric properties were seen to decrease with increasing gamma radiation dose, making the irradiated CuO NPs@PVP/PEO nanocomposite suitable for electrical applications.

Summary: A 1-D reactive-transport model was developed to study the production and transport of sulfide in a deep geological repository and the subsequent corrosion of the copper canister. The model considered various processes, including microbial reduction of sulfate, sulfate supply from groundwater and gypsum dissolution, diffusive transport, and sequestration of sulfide as mackinawite. The results indicated minimal uniform corrosion and flux below the threshold for localized corrosion or stress corrosion cracking after 1 million years.

Summary: This article proposes a safe and environmentally friendly material for corrosion removal from metals using a deep eutectic solvent. The solvent, composed of choline chloride and ascorbic acid, effectively dissolves corroded copper without aggressive effects on other materials.

Summary: This study prepared protective bilayer composite coatings based on polyetherimide (PEI) containing ZnO or CuO particles on mild steel (MS) using the sol-gel dip coating method. The morphology and composition of the coatings were confirmed by scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy dispersive spectroscopy (EDS) analysis. Attenuated total reflectance (ATR) analysis showed that the presence of oxide particles did not affect the polymer structure, while water contact angle tests revealed that PEI-CuO exhibited hydrophobic behavior, while PEI-ZnO and PEI alone showed hydrophilic behavior. Electrochemical impedance spectroscopy (EIS) analysis demonstrated that the PEI-CuO coating had impedance values above 5 x 10(5) Omega.cm(2) after immersion in NaCl for 8 days, representing a protective efficiency greater than 99%.

Summary: Canister performance is crucial for reliable deep geological repositories storing spent nuclear fuels, and corrosion resistance determines canister durability. A 2-D multiphysics model was developed to predict copper canister corrosion rate and potential in deep geological repositories. The corrosion through long-cell action was limited, demonstrating copper's sufficient corrosion resistance and canister durability of approximately 1.7 million years.

Summary: The corrosion behaviors of copper and tin in chloride-containing borate buffer solutions under UV illumination were studied. It was found that copper exhibited photoenhanced pitting corrosion while tin showed photo-induced passivation in a borate buffer solution containing 0.025 M NaCl. The effect of UV illumination on corrosion depended on the interaction between photo-generated carriers and metal oxides, as well as the photostability of the oxide film. Chloride anions were observed to decrease the photostability of the oxide film.

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 effect of pre-oxidation in air at 300-500°C on the initiation and development of liquid metal corrosion attack on 316L austenitic steel in static lead-bismuth eutectic (LBE) has been investigated. It was found that pre-formed oxide films can protect the surface against dissolution, while high temperature pre-oxidation leads to localized corrosion.

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.
