    An efficient green ionic liquid for the corrosion inhibition of reinforcement steel in neutral and alkaline highly saline simulated concrete pore solutions حسب Sliem, Mostafa H.

    منشور في 2020
    "…The inhibition efficiency was improved as the concentration of Q-32 and pH values were increased. However, it decreased as the temperature was raised. A Q-32 concentration of 20 µmol L–1 exhibited a 94% inhibition efficiency at 20 °C. …"

    Cyclic voltammetry and XPS studies of poly (aniline-co-3-aminophenol) حسب Waware, Umesh Somaji

    منشور في 2022
    "…In the electrochemical study, the copolymers differ from PA in the single-electron oxidation and reduction, reversibly at various scan rates ranging from 20 to 50 mV. The current density decreases from PA-co-3-AP20 to PA-co-3-AP80 by increasing the loading weight percentage of 3-aminophenol in the polymeric backbone. …"

    Performance of sustainable concrete incorporating treated domestic wastewater, RCA, and fly ash حسب Abushanab, Abdelrahman

    منشور في 2022
    "…This study evaluates the impact of using treated wastewater (TWW), recycled concrete aggregates (RCA), and fly ash (FA) on the mechanical, durability, and microstructural properties of concrete. A total of eight concrete mixes were manufactured and tested. …"

    Combined influence of temperature and flow rate of feeds on the performance of forward osmosis حسب Hawari, Alaa H.

    منشور في 2016
    "…It was also found that when increasing the draw solution (DS) temperature from 20 °C to 26 °C the flux increased linearly and then started decreasing when temperature increased over 26 °C due to the development of a temperature gradient. …"

    Iron Sulfide Scale Inhibition in Carbonate Reservoirs حسب Gasimli, Nijat

    منشور في 2022
    "…Moreover, the presence of the salts (CaCl2 and MgCl2) considerably decreased the adsorption of 10 wt % EDTA to 56% (CaCl2) and 52% (MgCl2) and caused nearly 20% more permeability reduction, while more inhibitor soaking time resulted in comparably higher adsorption and lesser permeability diminution. …"

    Flexural behavior of reinforced concrete beams prepared with treated Wastewater, recycled concrete Aggregates, and fly ash حسب Abushanab, Abdelrahman

    منشور في 2022
    "…The test parameters include mixing water type (fresh water and TWW), coarse aggregate type (natural gabbro and RCA), and FA content (0% and 20%). The results suggested that the use of TWW, RCA, and FA had no significant effect on the beams' cracking patterns and reinforcement strain at yielding, whereas TWW and RCA decreased the beams' ductility by 8.7% and 15.9%, respectively. …"
