  • Anomalous shear viscosity-temperature behaviour of jojoba oil/LDH-stearate suspensions 
    Focke, Walter Wilhelm; Moyo, Lumbidzani; Labuschagne, F.J.W.J. (Frederick Johannes Willem Jacobus); Hoosen, N.G.; Ramjee, Shatish; Saphiannikova, M. (Elsevier, 2014-02)
    Stearate intercalated layered double hydroxide was synthesized by reacting the corresponding carbonate form with a large excess of stearic acid. Thermal analysis, FTIR, XRD and SEMEDS characterization indicated the ...
  • A critical assessment of the methods for intercalating anionic surfactants in layered double hydroxides 
    Moyo, Lumbidzani; Nhlapo, N.S. (Nontete Suzan); Focke, Walter Wilhelm (Springer, 2008-08)
    Anionic surfactant intercalated layered double hydroxides (LDH) of high purity are easily prepared via direct coprecipitation and also by the ion exchange method provided that the precursor contains a monovalent anion, ...
  • Degradation of insecticides used for indoor spraying in malaria control and possible solutions 
    Sibanda, Mthokozisi Mayibongwe; Focke, Walter Wilhelm; Labuschagne, F.J.W.J. (Frederick Johannes Willem Jacobus); Moyo, Lumbidzani; Nhlapo, N.S. (Nontete Suzan); Maity, Arjun; Muiambo, H.F. (Herminio Francisco); Massinga, Pedro Horacio; Crowther, N.A.S. (Nicolaas Andries Sadie), 1944-; Coetzee, Maureen; Brindley, Gordon W.A. (BioMed Central, 2011-10-18)
    BACKGROUND: The insecticide dichloro-diphenyl-trichloroethane (DDT) is widely used in indoor residual spraying (IRS) for malaria control owing to its longer residual efficacy in the field compared to other World ...
  • Properties of layered double hydroxide micro- and nanocomposites 
    Moyo, Lumbidzani; Focke, Walter Wilhelm; Heidenreich, D.; Labuschagne, F.J.W.J. (Frederick Johannes Willem Jacobus); Radusch, Hans-Joachim (Elsevier, 2013-03)
    Carbonate and stearate intercalated layered double hydroxides were used as fillers to prepare polymer micro- and nanocomposites, respectively. The stearate modified starting material was bilayerintercalated clay. During ...
  • Thermal properties of lauric- and stearic acid intercalated layered double hydroxides 
    Focke, Walter Wilhelm; Nhlapo, N.S. (Nontete Suzan); Moyo, Lumbidzani; Verryn, Sabine Marie Charlotte (Taylor & Francis, 2010)
    A commercial layered double hydroxide (LDH) with nominal composition [Mg0.689A10.311(OH)2](CO3)0.156.zH2O was intercalated with lauric and stearic acid using a surfactant-assisted method. X-ray diffraction, thermal analysis ...
