- چکیده:
- چکیده انگلیسی: Crude oil is the main economic supply in many countries. Corrosion has been considered as the first fatal factor destroying the crude oil plants such as crude oil equipment, oil wells, separation vessels, storage tanks, and pipelines. This is the main reason encouraging many companies and researchers to develop new technological methods to manipulate corrosion. In this review, we discuss the types of corrosion, corrosion control methods (chemical and non -chemical methods), corrosion removal methods and corrosion monitoring process (direct and indirect measurement of corrosion). In addition some perspectives on SRB bacteria, types of inhibitors and gases removal methods were provided.

- چکیده:
- چکیده انگلیسی: Antibiotic-resistant pathogenic bacteria (e.g., multi-drug resistant bacteria, MDR) have been one of the major threats to human health. Nanoparticles, the newly emerging tools, hold the promise to solve the antibiotic resistance-related problems. This study aimed at evaluating the antibacterial activities of Ca-doped ceria nanoparticles (CDC) against the Gram-negative bacteria (Pseudomonas aeruginosa and Klebsiella pneumoniae) and Gram-positive bacteria (Staphylococcus aureus) using optical density measurement. Co-precipitation method was used to synthesize the Ca-doped ceria nanoparticles with and without addition of cetyltrimethylammonium bromide (CTAB, cationic surfactant). The prepared nanoparticles were characterized using the X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and UV-Vis spectroscopy. The XRD results demonstrated that, the CDC-CTAB nanoparticles (synthesized via CTAB-assisted co-precipitation method) had the smaller crystallite size (16.26 nm) and higher specific surface area (56.72 m2/g) compared to the CTAB-free synthesized sample (CDC nanoparticles). In addition, the CDC-CTAB nanoparticles exhibited a better inhibition percentage of bacteria growth (29.54-34.08%) against both the Gram-negative and Gram-positive bacteria. In terms of materials cost and toxicity, Ca-doped ceria nanoparticles can be considered as promising materials and, their biological activity might be evaluated against other microorganisms.
