Summary: Green corrosion inhibitors, such as Citrus limetta peel extract, have gained attention for their cost-effectiveness, biodegradability, and eco-friendly characteristics in inhibiting the corrosion of metallic alloys. This study investigates the corrosion inhibition efficiency of Citrus limetta peel extract on mild steel surfaces in an acidic environment using electrochemical methods. The results demonstrate that the extract exhibits a corrosion inhibition efficiency of 93% on mild steel surfaces in hydrochloric acid media. The adsorption mechanism of the peel extract on mild steel surfaces involves both physisorption and chemisorption.

Summary: The application of organic compounds, particularly heterocyclic compounds, as corrosion inhibitors is an effective and economical method to prevent steel corrosion. These compounds form a hydrophobic film on the metal surface to inhibit corrosion. The effectiveness of these compounds depends on the substituents present in their molecular structures. They block active sites responsible for corrosion through adsorption, mainly following the Langmuir adsorption isotherm model. These compounds act as mixed- and interface-type corrosion inhibitors, inhibiting both anodic and cathodic Tafel reactions and increasing charge transfer resistance.

Summary: Triazine derivatives TPA and DTT were synthesized in a one-step process and used as highly effective corrosion inhibitors for carbon steel in oil production. Experimental tests showed that TPA and DTT exhibited excellent inhibition performance with inhibition efficiencies of 97.8% and 99.1% respectively. The adsorptions of TPA and DTT on the steel surface were determined to be through the S, N, O atoms of TPA or the S, N atoms and phenyl ring of DTT.

Summary: A thick cementite skeleton exposed on a ferritic-pearlitic C1018 steel surface significantly reduced inhibition efficiency after pre-corrosion, while this effect was insignificant for a lower carbon X65 steel with dispersed cementite microstructure, as only a small amount of cementite remained on its surface after pre-corrosion. Normalizing the increased cathodic area in the presence of residual cementite back to the original area inhibited both anodic and cathodic reactions to the same extent as on bare steel with a sufficient inhibitor concentration. However, the detrimental effect of cementite cannot be completely eliminated due to its galvanic coupling effect.

Summary: Autonomous healing coatings based on hybrid organic-inorganic sol-gel coatings impregnated with chrome-free corrosion inhibitors such as Zr4+ and various rare-earth elements were investigated. The effects of direct addition of corrosion inhibitors and halloysite nanoclay encapsulated corrosion inhibitors on coating performance and self-healing action were evaluated. The study showed that coatings derived from the direct addition of Zr4+ and Ce3+ exhibited excellent performance, while all Z/RE-H coatings had a higher current density of 10(-6) A/cm(2) compared to other rare-earth elements and nanoclay encapsulated coatings.

Summary: This study investigates the use of anionic polyacrylamide hydrogels for the removal of cationic dye crystal violet from aqueous solutions. Batch adsorption studies show that the maximum adsorption capacity of the dye is 378 mg/g at an initial concentration of 300 mg/L, pH = 5, T = 298 K, and 0.039 g of the adsorbent. The adsorption mechanism follows the pseudo-second-order model, and the equilibrium adsorption follows the Langmuir model. Thermodynamic analysis suggests that the adsorption process is spontaneous and endothermic. Density functional theory (DFT), molecular dynamic (MD), and Monte-Carlo simulation studies were used to support the experimental findings.

Summary: Carbon nanocage structures, including fullerene, nanotubes, nanocapsules, nanopolyhedra, cones, cubes, and onions, have been extensively studied since the discovery of C60, and they hold great potential for investigating low-dimensional materials in an isolated environment. Boron Nitride (BN) nanomaterials, such as nanotubes, nanocapsules, nanoparticles, and clusters, have also been investigated and are expected to find applications in electronic devices, high heat-resistant semiconductors, nanocables, insulator lubricants, and gas storage materials. In this work, the interaction and electronic properties of octahedral B12N12 nanocage cluster covalently modified with alkyl and aryl radicals are analyzed using Density Functional Theory calculations. This study provides the first comprehensive investigation of the impact of grafted aryl and alkyl groups on the electronic properties, band gap, and density of states of B12N12, and it also presents the first complete description of these radicals attaching to the surface of B12N12 nanocage cluster.

Summary: Compatibility problems during the co-injection of corrosion and gas hydrate inhibitors in oil and gas pipelines were addressed using newly synthesized dual-purpose inhibitors (DPIs). Experimental and computational studies showed that DPIs effectively prevented gas hydrate formation and reduced corrosion rates on mild steel surfaces. Molecule dynamics simulations revealed that DPI2 disrupted gas transportation to hydrate cages and formed hydrogen-bonding networks for hydrate formation. These findings demonstrate the potential of DPIs for hybrid corrosion inhibition and gas hydrate prevention in flow assurance applications, leading to cost reduction.

Summary: Through monthly water quality monitoring in Lake Badovci using microbiological, physico-chemical, and diatomic indicators, we provided credible data regarding the quality of water in the lake. The highest levels of physicochemical and microbiological indices were found in January and February due to increased inflows from rivers caused by torrential rains. The diatomic indices showed that the lake has an excellent ecological status, except for some indices indicating a moderate ecological status and mesotrophic level.

Summary: In this study, a tetrafunctional epoxy resin called TGP was tested as a potential corrosion inhibitor for mild steel in 0.5 M H2SO4 solution. Various techniques were employed to investigate the corrosion inhibition process, including PDP, EIS, TE, SEM, EDS, and theoretical approaches. The results showed that at the optimal concentration (10(-3) M), the epoxy resin had corrosion efficacies of 85.5% (EIS) and 88.6% (PDP). The resin acted as an anodic inhibitor, forming a protective layer on the metal surface and preventing sulfur ion attack. DFT calculation and RDF, MC, and MD simulations provided further insights into the inhibitory efficiency of the epoxy resin.
