  • 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 ...
  • Fatty acid intercalated layered double hydroxides as additives for Jojoba oil and polymer matrices 
    Moyo, Lumbidzani (University of Pretoria, 2012)
    Fatty acid intercalated layered double hydroxides were used as additives for Jojoba oil and polymer matrices. The first phase of the study was to intercalate carboxylic acids (C14 to C22). These were successfully intercalated ...
  • 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 ...
