  • Deposition of SiC/Si coatings in a microwave plasma-assisted spouted bed reactor 
    Van Laar, Jean H.; Bissett, H.; Barry, J.C.; Van der Walt, I.J.; Crouse, Philippus L. (Elsevier, 2018-04)
    Silicon carbide (SiC) layers were deposited onto alumina particles in a microwave plasma-assisted spouted bed reactor using methyltrichlorosilane (MTS) and hydrogen mixtures, in argon, as precursor gas feed. The operating ...
  • Desulphurization of medium sulphur Waterberg steam coal in a batch operated scale : microbial solution 
    Makgato, Stanford S.; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)
    The current study evaluates pre-combustion microbial desulphurization of medium – sulphur type coal containing total sulphur (1.45 wt.%) and pyritic sulphur (≥ 0.51 wt. %) in a laboratory scale. Coal samples used in the ...
  • The effect of additives on the burning rate of silicon-calcium sulfate pyrotechnic delay compositions 
    Tichapondwa, Shepherd Masimba; Focke, Walter Wilhelm; Del Fabbro, Olinto; Labuschagne, George (Wiley, 2016-08)
    The effect of fuel particle size as well as the influence of inert and reactive additives on the burning rate of the Si-CaSO4 composition was evaluated. The burning rate decreased with increase in fuel particle size, while ...
  • Mn+Sb2O3 thermite/intermetallic delay compositions 
    Montgomery, Yolandi C.; Focke, Walter Wilhelm; Atanasova, Maria T.; Del Fabbro, Olinto; Kelly, Cheryl (Wiley, 2016-10)
    The binary Mn + Sb2O3 pyrotechnic composition was investigated for mining detonator time delay applications. EKVI thermodynamic modelling predicted two maxima in the adiabatic reaction temperature. The local maximum, at ...
  • Spontaneous microencapsulation of geraniol by zein 
    Ferreira, I.V.W. (Ignatius); Focke, Walter Wilhelm; Du Toit, Elizabeth Louisa (Budapest University of Technology, 2018)
    Geraniol was successfully micro-encapsulated with zein in a one-step phase separation process in which the zein and geraniol were both initially dissolved in a water-ethanol mixture. Microcapsules were only formed at ...
