  • Characterizing CaCO3 particle dispersion in blown film 
    Radebe, Lucky; Wesley-Smith, James; Focke, Walter Wilhelm; Ramjee, Shatish (De Gruyter, 2023-01)
    A novel method for the visualization and quantification of the state of dispersion of calcium carbonate particles in thin blown polymer films is described. Particle imaging was achieved by elemental mapping using energy ...
  • Formulating calcium carbonate masterbatches 
    Radebe, Lucky; Wesley-Smith, James; Focke, Walter Wilhelm; Ramjee, Shatish (De Gruyter, 2023-01)
    The effects of filler content, filler particle size and surface coating, as well as the natures of the wax and metal stearate lubricants on the properties of calcium carbonate-filled linear low-density polyethylene compounds ...
  • Malic acid production by aspergillus oryzae : the role of CaCO3 
    Geyer, Monique; Onyancha, Faith M.; Nicol, Willie; Brink, Hendrik Gideon (The Italian Association of Chemical Engineering, 2018)
    This study investigated the malic acid production capability of Aspergillus oryzae NRRL 3488 with three different CaCO3 concentrations, 20 g/L, 80 g/L, and 120 g/L, used as pH buffers and CO2 supply. A black box model ...
  • Microbial lead(II) precipitation : the influence of growth substrate 
    Brink, Hendrik Gideon; Mahlangu, Zanele (The Italian Association of Chemical Engineering, 2018)
    The objective of the study was to explore the influence of various growth substrates on the removal of aqueous lead from solution. The fermentation media tested consisted of glucose- and xylose-supplemented LB-broth, ...
  • The tensile behaviour of highly filled high-density polyethylene quaternary composites : weld-line effects, DIC curiosities and shifted deformation mechanisms 
    Viljoen, David; Fischer, Matthieu; Kühnert, Ines; Labuschagné, Johan (MDPI, 2021-02)
    The interactive effects between additives and weld lines, which are frequent injectionmoulding defects, were studied in high-density polyethylene (HDPE) and compared to weld-line-free reference samples. These materials ...
