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

    Published 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) by Waware, Umesh Somaji

    Published 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. …”

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

    Published 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 by Gasimli, Nijat

    Published 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 by Abushanab, Abdelrahman

    Published 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. …”

    The Separation of Emulsified Water/Oil Mixtures through Adsorption on Plasma-Treated Polyethylene Powder by Abdulkareem, Asma

    Published 2021
    “…The droplet size was directly proportional to sonication time and ranged from 135 nm to 185 nm. A sonication time of 20 min was found to be sufficient to prepare stable emulsions with an average droplet size of approximately 150 nm. …”

    Finite element study of functionally graded porous femoral stems incorporating body-centered cubic structure by Alkhatib, Sami E.

    Published 2019
    “…The highest micromotions (105‐147 µm) were observed for stems of 80% overall porosity, and the lowest (42‐46 µm) was for stems of 20% overall porosity. Finally, FGP stems with a grading exponent of n = 10 resulted in an 11%‐28% reduction in micromotions.…”
