Summary: Three gemini cationic surfactants with different hydrophobic tails were synthesized and confirmed spectroscopically. Surface tension measurements were conducted to examine their corrosion inhibition efficiency. It was found that the hydrophobicity and temperature affected their adsorption and micelle formation. The synthesized surfactants showed efficient affinity to mitigate steel corrosion, with GSBH exhibiting the highest inhibition efficiency of 94.5%. The adsorption of the inhibitors on C-steel was confirmed, and their behavior followed a modified Langmuir isotherm. The synthesized surfactants also showed affinity to mitigate sulfate reducing bacteria, with GSBO being the most effective.

Summary: In this study, effective Gemini cationic surfactants (CSII, CSIV) were synthesized and characterized. The adsorptive properties of CSII and CSIV at HCl/air and C-steel/HCl interfaces were investigated using surface tension and electrochemical parameters. The results showed that CSII and CSIV have high adsorption affinity at the HCl/air interface, with aliphatic chains promoting surfactant adsorption. Electrochemical impedance spectroscopy and potentiodynamic polarization revealed that CSII and CSIV act as mixed inhibitors, significantly enhancing the charge transfer resistance of C-steel in HCl. Theoretical calculations and simulations supported the experimental findings, demonstrating the relationship between corrosion inhibition and molecular structure.

Summary: Gold nanoparticles were deposited onto titania nanotubular layers using photocatalytic deposition and compared with composites prepared from gold colloidal solutions. The method of photodeposition affected the size, distribution, structure, and surface characteristics of the deposited gold nanoparticles. Photoreduction deposition resulted in higher activity in the oxygen electroreduction reaction compared to sol-modified electrodes, which can be attributed to the consolidation of the gold-TiO2 interface and the absence of ligands on the gold nanoparticles' surface.

Summary: Re-evaluation of conventional wastewater treatment processes is important for improving the quality of aquatic environment. Electrochemical Advanced Oxidation Processes (EAOPs) using Boron-doped diamond (BDD) technology show promising results in degrading and mineralizing water pollutants. This study uses systematic literature review and bibliometric analysis to assess the synergism between AO using BDD technology and other oxidation methods. The findings suggest that combining AO with add-ons or Fenton-based methods enhances degradation and mineralization efficiencies, and further research is needed for effective application in wastewater treatment facilities.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
