  • Characterizing the thermal phase behaviour of fipronil polymorphs 
    Moyo, Dennis Simbarashe; Van der Merwe, E.M. (Elizabet Margaretha); Rademeyer, Melanie; Malan, F.P. (Frederick); Atanasova, Maria T.; Mapossa, António Benjamim; Focke, Walter Wilhelm (Springer, 2023-07)
    This manuscript reports the investigation of the polymorphic behaviour of fipronil using a systematic comparison of the thermochemical and structural properties of different crystal forms obtained in this study as well as ...
  • A degradation study of polyamide 11/vermiculite nanocomposites under accelerated UV test 
    Kaci, Mustapha; Dehouche, Nadjet; Focke, Walter Wilhelm; Van der Merwe, E.M. (Elizabet Margaretha) (Wiley, 2019-12)
    Accelerated photooxidation under ultraviolet (UV) test of polyamide 11 (PA11) films filled with unmodified vermiculite clay at 5 wt% was investigated up to 600 h. Film samples of ~60‐μm thick were prepared by melt compounding ...
  • The effects of unmodified vermiculite on photooxidation of polyamide 11 nanocomposites under accelerated UV test 
    Kaci, Mustapha; Focke, Walter Wilhelm; Van der Merwe, E.M. (Elizabet Margaretha) (American Institute of Physics, 2018-07)
    The effects of unmodified vermiculite (UMVC) clay on the photooxidation of polyamide 11 (PA11) were investigated by accelerated UV test up to 600 h. The clay was incorporated to the polymer at a content ratio of 5 wt. %. ...
  • Influence of hydrating agents on the hydration of industrial magnesium oxide 
    Matabola, Kgabo P.; Van der Merwe, E.M. (Elizabet Margaretha); Strydom, C.A. (Christiena Adriana); Labuschagne, F.J.W.J. (Frederick Johannes Willem Jacobus) (Wiley-Blackwell, 2010-12)
    BACKGROUND: The influence of different hydrating agents on the pH of the hydrating solutions, rate of hydration of MgO to Mg(OH)2 and product surface area was studied as a function of temperature of hydration. Hydrating ...
  • Mosquito repellent thermal stability, permeability and air volatility 
    Mapossa, António Benjamim; Sitoe, Alcides Everildo José; Focke, Walter Wilhelm; Izadi, Homa; Du Toit, Elizabeth Louisa; Androsch, Rene; Sungkapreecha, Chanita; Van der Merwe, E.M. (Elizabet Margaretha) (Wiley, 2020-03)
