Summary: The objective of this study was to improve the protection of metallic structures against corrosion by combining organic corrosion inhibitors (tannins derived from pine bark) with anodic protection using chemically modified zinc oxide nanoparticles. Film evaluations were conducted according to ISO and ASTM standards. The study also evaluated the performance of two commercial coatings and conducted electrochemical impedance spectroscopy (EIS) characterizations at different exposure times. The results showed that the combination of tannins and encapsulated zinc oxide nanoparticles is a viable alternative to commercial coatings with synthetic compounds, providing high-performance corrosion protection.

Summary: This paper presents insights obtained after experimental research on the influence of input variables (the content of anticorrosive pigment in the coating, dry-film thickness, and conditioning time) on corrosion resistance of two-component epoxy coatings. The results show that the content of anticorrosive pigment and dry-film thickness have the greatest impact on the protective properties of the coating, while the conditioning time has a lesser influence.

Summary: Nanocomposites of p-type NiO/n-type ZnO heterojunction with varying NiO content were synthesized by sol-gel method, showing superior photocatalytic activity and corrosion resistance. Among the fabricated semiconductors, NiO/ZnO nanocomposites with 5% NiO demonstrated the best performance in degrading methylene blue dye. Increasing layer thickness and co-dopant concentration improved the corrosion resistance of the gel coating system on aluminum electrodes.

Summary: An organic-inorganic composite coating consisting of polyaniline (PANI) and aluminum tripolyphosphate (ATP) was prepared and applied on 304 stainless steel (304ss) for anti-corrosion treatment. The coating exhibited excellent corrosion resistance, as evidenced by the significant increase in low-frequency impedance and reduction in corrosion current density compared to bare steel. Its anti-corrosion performance remained superior even after long-term immersion experiments.

Summary: The inhibitory effects of sodium abietate (SA) and sodium lignin sulfonate (SLS) on the corrosion of AA2024-T3 Aluminum alloys in NaOH media were investigated. Experimental results showed that SA and SLS exhibited significant inhibition efficiency, reaching up to 96.02% and 98.82% at 5 x 10 -3 mol center dot L -1, respectively. Electrochemical methods confirmed that SA and SLS acted as anode-dominated mixed-type inhibitors. Surface analyses revealed the formation of an adsorbed film on the metal surface in the presence of SA and SLS. The adsorption of SA and SLS followed Langmuir isotherm and exhibited a combination of physical and chemical adsorptions. Quantum chemical calculations and molecular dynamics simulation provided insights into the inhibitive action of SA and SLS. This study suggests SA and SLS as eco-friendly options for anticorrosive applications.

Summary: Tannins have the ability to form complexes with proteins, limiting their degradation and thus inhibiting the synthesis of certain odour-active compounds. Different types of tannins can influence the volatile profile and flavour of meat, with tannin extracts reducing pastoral odour in lamb meat.

Summary: This study evaluates the corrosion of aluminum coupons using bacterial and fungal isolates, and synthesizes aluminum nanoparticles for anticorrosion testing. The results showed that the corrosion rate in the bacterial treated group (0.032 mm/y) was higher than that in the fungal treated group (0.026 mm/y), due to the corrosive environment created by microbial colonies. The synthesized nanoparticles exhibited good anticorrosion properties, as observed by scanning electron microscopy.

Summary: This study introduces a novel green corrosion inhibitor, Gliricidia sepium leaf extract, and investigates its anticorrosive activity on steel in a saline environment. The major corrosion inhibitor identified in the extract is sucrose, which contributes to the development of a protective layer at the metal-electrolyte interface. The prepared organic-inorganic hybrid coating offers exceptional corrosion resistance and shows promise for future applications in protective polymer coatings.

Summary: The addition of tara and quebracho colorado tannins significantly reduces the corrosion rate of aluminum in near-neutral and naturally aerated NaCl solutions. The tannins act as a mixed-type corrosion inhibitor and form a more homogenous and compact layer on the aluminum surface, preventing the adsorption of chlorinated compounds. The experimental results demonstrate the improved corrosion resistance of aluminum in the presence of tannins.
