This work investigated the effect of Desulfovibrio caledoniensis (D. caledoniensis) and Pseudomonas aeruginosa (P. aeruginosa) on microbiologically influenced corrosion (MIC) behaviour 70Cu-30Ni alloy using surface analysis electrochemical techniques. The results demonstrated that mixed medium containing D. P. further accelerated MIC compared to single species medium. addition exogenous pyocyanin (PYO) increased maximum pit depth from 5.40 μm 6.59 μm, current density (icorr) by one order magnitude. From perspective bioenergetics extracellular electron transfer (EET), comprehensive mechanism induced was proposed.

Numerous strategies have been developed for the corrosion protection of steel; however, most them a significant environmental impact and employ toxic compounds. Tannins are green promising solution sustainable strategies. In this context, work was focused on natural (condensed hydrolysable) tannin layers as possible strategy carbon steel. The tannins’ dissolution medium (ultrapure water or Phosphate-Buffered Saline), surface pre-treatment (acid pickling plasma), deposition technology (dipping spin coating) layer homogeneity adhesion has evaluated. effects these parameters coating formation, homogeneity, investigated by means visual inspections, swabbing, Fourier Transformed Infrared spectroscopy (FTIR), Scanning Electron Microscopy equipped with Energy Dispersive Spectroscopy (SEM-EDS) tape tests. Preliminary electrochemical tests performed material (carbon steel acid pickled coated hydrolysable solved in to estimate protective ability highlight main criticisms be overcome.

Graphitic carbon nitride (g-C3N4, CN) has emerged as a promising photocatalytic material due to its inherent stability, antibacterial properties, and eco-friendliness. However, tendency aggregate limited dispersion hinder efficacy in practical applications. To address these limitations, this study focuses on developing composite hydrogel coating, which sodium alginate (SA) molecules interact electrostatically through hydrogen bonding anchor CN, thereby significantly improving dispersion. The optimal CN loading of 35% results with tensile strength 120 MPa an rate 99.87% within 6 h. enhanced mechanical properties are attributed between the -NH2 groups -OH SA, while SA facilitate attraction photogenerated holes from promoting carrier transfer separation, strengthening action. Moreover, coating exhibits excellent corrosion resistance capabilities against Pseudomonas aeruginosa 316L stainless steel (316L SS), laying foundation for advanced antimicrobial anticorrosion systems.
