    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). …”

    Spatial-temporal pattern of cultivated land productivity based on net primary productivity and analysis of influencing factors in the Songhua River basin by Yang, Shiliang

    Published 2022
    “…Meanwhile, this scientific study examined the spatio-temporal heterogeneity of cultivated land productivity (CLP) and determined the effect intensity and the direction of effect of various factors on productivity, using the Songhua River Basin (SRB) in China as a research case. We used genetic algorithms to modify and improve a neural network model of factor dimensionality reduction, combined with path analysis, cluster analysis, and regression analysis, to identify the main factors impacting CLP, synergies between these factors, and effect intensity and direction. …”
