  • Blooming of chlorfenapyr from polyethylene films 
    Mapossa, António Benjamim; Moyo, Dennis Simbarashe; Wesley-Smith, James; Focke, Walter Wilhelm; Androsch, Rene (American Institute of Physics, 2020-11)
    FTIR, in ATR and in transmission modes, enabled the tracking of the migration of the insecticide Chlorfenapyr to the surface of a polymer film. It also allowed estimation of the apparent solubility in the polymer. However, ...
  • Blooming of insecticides from polyethylene mesh and film 
    Mapossa, António Benjamim; Sibanda, Mthokozisi Mayibongwe; Moyo, Dennis Simbarashe; Kruger, Taneshka; Focke, Walter Wilhelm; Androsch, Rene; Boldt, Regine; Wesley-Smith, James (Taylor and Francis, 2021)
    Malaria remains a public health concern with vector control still the vital component of disease prevention, control, and elimination strategies. Recent years has seen a “stalling” in the progress made towards the reduction ...
  • Cellulose acetate/organoclay nanocomposites as controlled release matrices for pest control applications 
    Mphateng, Thabang N.; Mapossa, António Benjamim; Wesley-Smith, James; Ramjee, Shatish; Focke, Walter Wilhelm (Springer, 2022-05)
    This study aimed to develop cellulose-based polymer matrices as controlled release devices for plant-based insect repellents and attractants, with the aim of finding sustainable and environmentally friendly pest control ...
  • Development, characterization and modeling of mosquito repellent release from microporous devices 
    Sitoe, Alcides Everildo José; Mapossa, António Benjamim; Focke, Walter Wilhelm; Muiambo, Herminio; Androsch, René; Wesley-Smith, James (Wiley, 2020-12)
    Nanocomposite strands with mosquito repellent DEET or Icaridin incorporated in a poly(ethylene-co-vinyl acetate) (EVA) matrix, with either pyrogenic silica or an organoclay as a nanofiller, were prepared by a twin-screw ...
  • Estimating binary liquid composition from density and refractive index measurements : a comprehensive review of mixing rules 
    Pretorius, Franco; Focke, Walter Wilhelm; Androsch, Rene; Du Toit, Elizabeth Louisa (Elsevier, 2021-04)
    A comprehensive review of refractive index mixing rules of binary solutions is presented. All published mixing rules, with the exception of the Wiener mixing rule, can be reformulated into expressions with a linear dependence ...
  • Mosquito repellent microporous polyolefin strands 
    Mapossa, António Benjamim; Focke, Walter Wilhelm; Sitoe, Alcides Everildo José; Androsch, Rene (American Institute of Physics, 2020-11)
    Pyrogenic silica and organoclay nanocomposite strands containing liquid mosquito repellents were prepared by twinscrew extrusion compounding. The mosquito repellents DEET and Icaridin were immobilized in the pores of a ...
  • 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)
    Please read abstract in the article.
  • A promising azeotrope-like mosquito repellent blend 
    Izadi, Homa; Focke, Walter Wilhelm; Asaadi, Erfan; Maharaj, Rajendra; Pretorius, Jannie; Loots, Mattheus Theodor (Nature Publishing Group, 2017-08-31)
    Topical repellents play a key role in reducing the outdoor transmission of mosquito-borne diseases by reducing human-vector contact. Excellent repellents are available, but there is always room for improvement. This ...
  • Properties of mosquito repellent-plasticized poly(lactic acid) strands 
    Mapossa, António Benjamim; Lopez-Beceiro, Jorge; Diaz-Diaz, Ana Maria; Artiaga, Ramon; Moyo, Dennis Simbarashe; Mphateng, Thabang N.; Focke, Walter Wilhelm (MDPI Publishing, 2021-09-28)
    Poly(lactic acid) (PLA) is an attractive candidate for replacing petrochemical polymers because it is fully biodegradable. This study investigated the potential of PLA as a sustainable and environmentally friendly ...
