  • Advanced eva nanocomposites : developments and new opportunities 
    Gnanasekaran, Dhorali; Massinga, Pedro Horacio; Focke, Walter Wilhelm (Nova Science Publishers, 2015)
    The paper presents a complete conspectus of ethylene-co-vinyl acetate (EVA) nanocomposites based on different types of nanostructured materials incorporated into EVA polymers. The three types of nanostructured materials, ...
  • Alkyl ammonium intercalation of Mozambican bentonite 
    Massinga, Pedro Horacio; Focke, Walter Wilhelm; De Vaal, Philip L.; Atanasova, Maria Todorova (Elsevier, 2010-07)
    Organo-bentonites containing quaternary ammonium surfactants were prepared using purified bentonite from the Boane deposit in Mozambique. The intercalation was effected by intimate mixing of the surfactants into a concentrated ...
  • Co-intercalation of insecticides with hexadecyltrimethylammonium chloride in Mozambican bentonite 
    Merckel, Ryan David; Focke, Walter Wilhelm; Sibanda, Mthokozisi Mayibongwe; Massinga, Pedro Horacio; Crowther, N.A.S. (Nicolaas Andries Sadie), 1944- (Routledge, 2012-02)
    WHO-approved insecticides were co-intercalated with hexadecyl-trimethylammonium (HDTMA) chloride in bentonite in an attempt to improve their persistence. XRD and FTIR confirmed successful co-intercalation of the insecticides. ...
  • 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 ...
  • EVA nanocomposites based on South African Koppies clay 
    Massinga, Pedro Horacio; Focke, Walter Wilhelm; Del Fabbro, Olinto; Radusch, Hans-Joachim (Wiley, 2014-09)
    South African Koppies bentonite was organo-modified with single tail and double tail alkyl ammonium cationic surfactants with the latter intercalated both below and above the clay CEC. Corresponding poly(ethylene-co-vi ...
  • Intercalating cationic surfactants in Koppies bentonite 
    Massinga, Pedro Horacio; Focke, Walter Wilhelm (Routledge, 2012-02)
    Single and double chain cationic surfactants were intercalated into Koppies bentonite. The state of the chains in the interlayers was probed using XRD, FTIR spectroscopy and thermogravimetric analysis (TG). The degree ...
