    Recycled Waste Tires Management in Constructions by Hamid, Salma Mohamed

    Published 2020
    “…The LCCA results show that the rubberized concrete (RC2), obtained by replacing 5% of aggregate and mixing it with seawater, is more cost-effective than RC1, with a cost savings of 30%.LCCA data were acquired by investigating thirteen concrete mixes (a control mix; 5%, 10%, and 20% rubber aggregate substitutions mixed with freshwater; and 0%, 5%, and 10% rubber aggregate substitutions mixed with seawater). …”

    Morphology, nucleation, and isothermal crystallization kinetics of poly(butylene succinate) mixed with a polycarbonate/MWCNTs masterbatch by Gumede, Thandi P.

    Published 2018
    “…The nanocomposites contained 0.5, 1.0, 2.0, and 4.0 wt% MWCNTs. Differential scanning calorimetry (DSC), small angle X-ray scattering (SAXS) and wide angle X-ray scattering (WAXS) results indicate that the blends are partially miscible, hence they form two phases (i.e., PC-rich and PBS-rich phases). …”

    Screening of Qatari Microalgae and Cyanobacteria for Application in CO2 Utilization by Schipper, Kira

    Published 2018
    “…The tolerance of the strains to increased concentrations of CO2 in the gas phase was also studied for CO2 concentrations ranging from 5% to 30% (v/v). With productivities of 53.7 ± 11.4, 162.2 ± 5.4, 333.8 ± 29.1 and 312.8 ± 12.8 mg L-1 d-1 for 5, 10, 20 and 30% CO2 respectively, Tetraselmis sp. showed that a significant productivity increase could be obtained with increased CO2 concentrations. …”

    Prospects Of Amino Acids And Ionic Liquids As Natural Gas Hydrate Inhibitors For Offshore Flow Assurance by Qureshi, M. Fahed Aziz

    Published 2018
    “…The inhibitors tend to show better hydrate inhibition effect at low pressures (40 bars) and their inhibition effect decreases as the pressure rises. At the same concentration (10 wt%), the ammonium-based ionic liquid [EA][Of] provided the inhibition effect similar to MEG and at the higher concentration (20 wt%) the amino acid glycine provided better hydrate inhibition effect than the MEG. …”
