Corrosion Inhibition of Mild Steel using Potato Peel Extract in 2M HCl Solution حسب Ibrahim, Taleb

"…A reasonable corrosion inhibition level was obtained at a concentration of 50 ppm (>70% inhibition efficiency). Nyquist plots from Impedance data showed that upon increasing the PPE concentration, the charge transfer resistance increased and the doubled layer capacitance decreased. …"

Recyclable polyaspartate-coated magnetic nanoparticles for sustainable control of calcite and barite scales in oilfield operations حسب Abdelrahman T. Abdelaal (14674629)

"…Dynamic tube-blocking tests at 100 °C and 1000 psi further confirm effective scaling suppression for 60 min at 50 ppm, demonstrating that immobilization of PASP on a magnetic carrier preserves its intrinsic inhibitory function while enabling recyclable deployment not achievable with free PASP. …"
