“…The gram-negative bacteria are more resistant to antibiotics than that of gram-positive bacteria, fungi and yeast. The presence of outer membrane of the Gram-negative bacterial cell wall contains lipopolysaccharide molecules acting as a barrier to the penetration of antibacterial substances making the Gram-negative bacteria more resistant to antibiotics [47][48][49][50][51]. It appears from the data shown in Table 4, that the antibiotic effect of our prepared cationic surfactants is higher on gram-positive bacteria, fungi and yeast than Gram-negative bacteria.…”

Three cationic surfactants containing amide groups were prepared by quaternization of dimethylaminopropylamine with benzyl chloride. FTIR and 1 H-NMR spectroscopy were used to confirm the chemical structure of the prepared cationic surfactants. The surface parameters were estimated using surface tension measurements at three different temperatures. The prepared cationic surfactant showed a lower CMC than conventional cationic surfactants. Thermodynamic parameters of adsorption and micellization depend mainly of alkyl chain length and temperature. The adsorption process is more favorable than micellization. The biological activity of the three surfactants was estimated using inhibition zone showing that amidoamine cationic surfactants have good activity and the surfactants C12Bn is the most effective one.

“…In cathodic polarization curves, the current reaches a peak value and then stabilizes at a plateau value that is relatively constant (limiting current i L ) and this shows that the predominant cathodic reaction in the corrosion of copper in 0.1 M H 2 SO 4 is the reduction of oxygen gas at the cathodic sites (Shaban et al., 2015) of copper electrode. The polarization curves were analyzed, and the values of polarization parameters, the corrosion potential: E corr.…”

“…Figure 4 shows the Nyquist plots for copper in 0.1 M H 2 SO 4 at 25 C. The capacitive loops at low the high frequencies region are ended by the diffusion tail at the low frequency region. This locus of impedance Nyquist plots indicated that the corrosion of copper in 0.1 M H 2 SO 4 is under diffusion control (Ma et al, 2002;Shaban et al, 2015).…”

A novel, cheap, less toxic, and easier-prepared gelatin surfactant is successfully used as corrosion inhibitor for the corrosion of copper in 0.1 M H 2 SO 4 at the temperature range: 25-55 C. The critical micelle concentration of the surfactant was determined from surface tension measurements. The inhibition efficiency was determined from potentiodynamic polarization and electrochemical impedance spectroscopy techniques. For surfactant acted by adsorption at copper/solution interface, an inhibition efficiency up to 68 was obtained at critical micelle concentration (70 ppm) of surfactant at 35 C. The free energy of adsorption was calculated and discussed. The surface parameters of gelatin surfactant were calculated and correlated to the inhibition efficiency. They were also calculated from its surface tension profile including: critical micelle concentration), maximum surface excess (C max ), and minimum surface area (A min ). The thermodynamic of micellization, free energies of micellization (DG mic ) and entropy of micellization, was calculated and discussed. The formation of compact and adherent monomolecular adsorbed film on copper substrate was confirmed.

“…In the FTIR spectrum (Fig. ) of the zwitterionic surfactant before aging, the two stretching vibrations at 2920 and 2849 cm −1 were seen corresponding to the methyl (–CH 3 ) and methylene (–CH 2 –) groups in the hydrophobic tail (Dardir, Mohamed, Farag, Ramdan, & Fayad, ; El‐Lateef, Abo‐Riya, & Tantawy, ; Shaban, Aiad, Fetouh, & Maher, ). The stretching vibration of the carbonyl group was observed at 1641 cm −1 and C–N stretching vibration was detected at 1070 cm −1 (Zaky, Badawi, El Sabbah, Ghani, & Hendawy, ).…”

High-temperature/high-salinity (HTHS) reservoirs contain a significant fraction of the world's remaining oil in place and are potential candidates for enhanced oil recovery (EOR). Selection of suitable surfactants for such reservoirs is a challenging task. In this work, two synthesized zwitterionic surfactants bearing a saturated and an unsaturated tail, namely 3-(N-stearamidopropyl-N,N-dimethyl ammonium) propanesulfonate and 3-(N-oleamidopropyl-N,N-dimethyl ammonium) propanesulfonate, respectively, were evaluated. The surfactant with the unsaturated tail showed excellent solubility in synthetic seawater (57,643 ppm) and in formation brine (213,734 ppm). However, the unsaturated surfactant with a saturated tail showed poor solubility, and therefore it was not evaluated further. The thermal stability of the synthesized unsaturated surfactant solution in seawater was evaluated by heating the solution at 90 C in a sealed aging tube for 2 weeks. The thermal stability of the unsaturated surfactant was confirmed by FTIR and NMR analysis of the aged samples at such harsh conditions. The critical micelle concentration (CMC) of the synthesized unsaturated surfactant in seawater was 1.02 × 10 −4 mol L −1 , while the surface tension at CMC was 30 mN m −1 . The synthesized unsaturated surfactant was able to reduce the oil-water interfacial tension tõ 10 −1 mN m −1 at different conditions. A commercial copolymer of acrylamide and 2-acrylamido-2-methylpropane sulfonic acid (AM-AMPS) was tested for EOR applications in HTHS conditions. The addition of the synthesized unsaturated surfactant to the AM-AMPS copolymer increased the viscosity of the system. The increase in oil recovery by injecting the unsaturated surfactant solution and the surfactant-polymer mixture in solution was 8 and 21%, respectively. The excellent properties of the synthesized unsaturated surfactant show that surfactants with an unsaturated tail can be an excellent choice for HTHS reservoirs.
