Summary: Anodic polarization treatment was used to investigate the microbiologically influenced corrosion (MIC) behavior of 316 L-Cu stainless steel against marine Pseudomonas aeruginosa. The results showed that the treatment decreased the corrosion current and increased the pitting potential of 316 L-Cu stainless steel compared to conventional 316 L stainless steel. Surface morphology observations and XPS analysis revealed that 316 L-Cu stainless steel effectively inhibited bacterial reproduction and promoted the formation of a protective extracellular polymeric substance (EPS)-Fe membrane, leading to reduced susceptibility to pitting corrosion compared to 316 L stainless steel.

Summary: The presence and activities of microorganisms can affect corrosion on metal surfaces. This study investigated the dynamics and differences in microbial communities on various types of stainless steels before and after corrosion incidents. The results showed that non-corroded stainless steels had slowly altered microbial communities with decreased diversity over time, while corroded stainless steels had low diversity microbial communities with enrichment of specific bacteria. The findings suggest that the composition of the stainless steel did not significantly affect the microbial communities on healthy metal surfaces.

Summary: The microbiologically influenced corrosion (MIC) behavior of 304 stainless steel by sulfate-reducing bacteria (SRB) in ZnO nanofluids was investigated. The results showed that ZnO nanoparticles (NPs) had little effect on the corrosion resistance of stainless steel but effectively inhibited the MIC and reduced the adhesion of biofilm. This was due to the antibacterial effect of ZnO NPs, which reached 89.5% at a concentration of 100 mg/L. Electrochemical tests revealed that the presence of ZnO NPs decreased the passive current density, increased the film resistance, and inhibited the MIC in ZnO nanofluids containing SRB. The antibacterial effect of ZnO NPs was attributed to the generation of strongly oxidizing ·OH in water, which inhibited the formation of biofilm and deposition of sulfide on stainless steel surface, thereby slowing down the corrosion damage caused by SRB.

Summary: The study demonstrated that D-cysteine (D-cys) can inhibit the formation of Pseudomonas aeruginosa biofilms on stainless steel surfaces, thereby reducing the microbiologically influenced corrosion (MIC) rate. X-ray photoelectron spectroscopy (XPS) analysis and scanning electrochemical microscopy (SECM) analysis showed that the biofilm inhibition effect of D-cys greatly decreased the destructive effect of Pseudomonas aeruginosa cells on the passive film of stainless steel, ultimately inhibiting MIC.

Summary: Due to its excellent resistance to corrosion, stainless steel has a broad employment scope in oilfields. However, it is defenseless against microbiologically influenced corrosion (MIC). Microorganisms directly cause corrosion by releasing disruptive metabolites or collecting electrons from the metal for breathing. Only a few successful reports on combating MIC have been published. This article provides a comprehensive review of studies on stainless steel in the presence of microorganisms and analyzes microbiological contamination. It highlights the importance of understanding the various factors involved in selecting a certain material for a specific purpose.

Summary: The microbiologically influenced corrosion of 201 stainless steel by Shewanella algae was studied by modulating the concentration of fumarate in the medium and constructing mutant strains induced by ∆OmcA. Results from ICP-MS and electrochemical tests showed that the presence of S. algae enhanced the degradation of the passive film, which was further aggravated by the lack of an electron acceptor, mainly affecting the early stage of MIC. Electrochemical tests and atomic force microscopy characterization revealed that the ability of ∆OmcA to transfer electrons to the passive film was reduced in the absence of the c-type cytochrome OmcA associated with EET progress, resulting in a lower corrosion rate of the steel.

Summary: The effect of Cu addition on the corrosion behavior of 304 austenitic stainless steel was studied through various tests and analyses. The results showed that 304Cu exhibited higher corrosion resistance than 304 in a NaCl solution, but the beneficial effect of Cu diminished after prolonged exposure. Both penetrating and non-penetrating corrosion pits were observed on both steel types after immersion in a FeCl3 solution, but the corrosion rates of 304Cu were much higher. Cu and Cu2+ were the main forms of Cu in the as-received 304Cu, and Cu+ formed during corrosion in chloride solutions. The study highlights the importance of considering the corrosion resistance of steel in aggressive environments for long-term exposure.

Summary: Photocatalytic technology utilizing sunlight as a driving force can convert solar energy into other energy sources for storage and use. CdS, as a typical reducing semiconductor, has attracted attention in photocatalysis due to its suitable bandgap and strong reducing ability. However, the photocatalytic performance of CdS is limited by carrier recombination and photocorrosion. Therefore, CdS has been widely developed as a reducing photocatalyst in constructing S-scheme heterojunctions to overcome these limitations.

Summary: A novel compliant spinal fixation based on compliant mechanisms is designed to effectively reduce stress-shielding effect and adjacent segment degeneration (ASD), but it requires high properties of the used materials. Bulk metallic glasses (BMGs), as young biomaterials, demonstrate excellent comprehensive properties, making them attractive for compliant spinal fixation. In this study, the large deflection deformation behaviors of Zr61Ti2Cu25Al12 (at.%, ZT1) BMG beam were systematically investigated, including elastic, yielding, and plastic deformations. The theoretical nonlinear analytical solution curve predicts the load-deflection relation within the elastic deformation regime and assists in capturing the yielding event, serving as a powerful design tool for engineers. To accurately capture the beginning of the yielding event in biomedical implant applications, the concept of bending proof strength (sigma p,0.05%) with tiny permanent strain of 0.05% was proposed and determined, which is significant for setting the allowable operating limits of the basic flexible elements. The plastic deformation driven by the bending moment can be classified into two stages: the initial stage characterized by nucleation and intense interaction of shear bands, and the second stage dominated by the progressive propagation of shear bands and emergence of shear offsets. The plasticity of BMG beam structures depends on the BMG's inherent plastic zone size (rp), and when the half beam thickness is less than that of rp, the plastic deformation of BMGs behaves in a stable manner, effectively serving as the margin of safety.

Summary: Fe-based metallic glasses are promising materials in the fields of advanced magnetism and sensors. This study proposes a novel approach to tailor the amorphous structure through liquid-liquid phase transition, and provides insights into the correlation between structural disorder and magnetic order. The results show that the liquid-liquid phase transition can induce more locally ordered nanodomains, leading to stronger exchange interactions and increased saturation magnetization. The increased local heterogeneity also enhances magnetic anisotropy, resulting in a better stress-impedance effect.

Summary: Metal-organic frameworks derived composites are promising EMW absorbers. Cation substitution can improve their absorption performance by regulating morphology and atomic space occupation. However, the mechanisms of how cation substitution affects EMW absorption performance are still not well understood. In this study, imidazolic MOFs were fabricated and tailored by cation substitution strategy to prepare porous composites. The samples showed optimal reflection loss and effective absorption bandwidth values under low filling rate and thin thickness conditions. The intercoupling between multiple atoms and the porous structure introduced by cation substitution contribute to the improved absorption performance.
