    Morphology, Nucleation, and Isothermal Crystallization Kinetics of Poly(ε-caprolactone) Mixed with a Polycarbonate/MWCNTs Masterbatch حسب Gumede, Thandi P.

    منشور في 2017
    "…Isothermal crystallization experiments performed by DSC showed an increase in the overall crystallization kinetics of PCL with increases in MWCNTs as a result of their nucleating effect. Nevertheless, the crystallinity degree of the nanocomposite containing 4 wt % MWCNTs decreased by about 15% in comparison to neat PCL. …"

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

    منشور في 2018
    "…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). The PC-rich phase contained a small amount of PBS chains that acted as a plasticizer and enabled crystallization of the PC component. …"

    Release of colloids in saturated porous media under transient hydro-chemical conditions: A pore-scale study حسب Nishad, Safna

    منشور في 2021
    "…Favorable, medium-favorable and unfavorable colloids (i.e., repulsion absent, repulsion at long-range of separation distances and attraction absent with the micromodel surface, respectively) were deposited in the micromodel and then a series of colloid release experiments were conducted at different conditions including increasing the flow rate, decreasing the ionic strength and increasing the solution pH. …"

    Development of a stacked machine learning model to compute the capability of ZnO-based sensors for hydrogen detection حسب Behzad, Vaferi

    منشور في 2024
    "…Trend and relevancy analyses indicated that the sensor sensitivity intensifies with increasing hydrogen concentration and decreasing temperature. The reduced graphene oxide (rGO) dose initially improves sensor sensitivity toward hydrogen detection up to a maximum value and then continuously decreases it. …"
