  • Development and size distribution of Polystyrene/ZnO nanofillers 
    Ayeleru, Olusola Olaitan; Dlova, Sisanda; Ntuli, Freeman; Kupolati, Williams Kehinde; Olubambi, Peter Apata (Elsevier B.V., 2019-04)
    In this paper, the preparation and characterization of ZnO nanofillers from polystyrene (PS) polymer waste for use as reinforcement was presented. This was done to achieve a better means of upcycling polymer wastes that ...
  • Effectiveness of using milled Moringa Oleifera seeds as a disinfectant in waste water treatment 
    Tsie, Mpho Edwin; Ntuli, Freeman; Lekgoba, Tumeletso (The Mattingley Publishing Co., Inc, 2020-01)
    Water disinfection is a crucial water treatment process because it deals with the removal of pathogens to make water safe to drink. Moringa oleifera extract was used as a disinfectant and the total coliform count was ...
  • Energy densification of animal waste lignocellulose biomass and raw biomass 
    Pahla, Godwell; Mamvura, Tirivaviri Augustine; Ntuli, Freeman; Muzenda, Edison (Institution of Chemical Engineers ,Published by Elsevier, 2017-06)
    The need to reduce carbon emissions has encouraged more research into use of biomass energy in place of coal. Biomass is carbon neutral; its use can therefore lower net emissions. Biomass can be upgraded to a fuel similar ...
  • Influence of coal properties on coal conversion processes-coal carbonization, carbon fiber production, gasification and liquefaction technologies: a review 
    Keboletse, Kamogelo P.; Ntuli, Freeman; Oladijo, Oluseyi Philip (Springer Nature Switzerland AG., 2021-02-08)
    Coal due to its relatively large quantities and wide distribution worldwide has generated renewed interest in research and development with the aim of establishing coal conversion technologies that are technically reliable, ...
  • Influence of pyrolyzed sludge use as an adsorbent in removal of selected trace metals from wastewater treatment 
    Matheri, Anthony Njuguna; Eloko, Nicelette Shako; Ntuli, Freeman; Ngila, Jane Catherine (Elsevier Ltd, 2020-09)
    The disposal of sludge processes accounts for 60% of the total operation and 40% of total emissions of greenhouse gas from wastewater treatment plants operations. Moreover, sludge contains pathogenic microorganisms, organics, ...
  • Manufacture of fly ash based coagulants for use in water treatment 
    Maila, Goitseone Baby; Ntuli, Freeman; Lekgoba, Tumeletso (: The Mattingley Publishing Co., Inc, 2020-01)
    Fly ash was explored as a raw material for the production of three fly ash-based coagulants being raw, calcined and calcined– sodium hydroxide complex coagulants. Calcined fly ash and calcined fly ash – sodium hydroxide ...
  • Optical properties of bimetallic (SrO-K2O) nanofillers 
    Ayeleru, Olusola Olaitan; Dlova, Sisanda; Ntuli, Freeman; Kupolati, Williams Kehinde; Olubambi, Peter Apata (Elsevier B.V., 2019-04)
    In this study, bimetallic nanofiller capable of usage as reinforcement was synthesized from expanded polystyrene (EPS). Bimetallic materials consist of two different metals. The bimetallic nanofiller consisting of SrO and ...
  • Sulphate removal from acid rock drainage using steel slag 
    Ntuli, Freeman; Magwa, Nomampondo (IOP Publishing Ltd, 2018-07)
    The removal of sulphates from acid rock drainage (ARD) using basic oxygen furnace (BOF) slag was investigated. The results indicated that sulphates removal using BOF- slag increased with temperature increase (25-45oC), ...
  • Synthesis and characterization of SnO2 nanofiller from recycled expanded polystyrene 
    Ayeleru, Olusola Olaitan; Dlova, Sisanda; Ntuli, Freeman; Kupolati, Williams Kehinde; Olubambi, Peter Apata (Elsevier B.V., 2019-04)
    Polymer waste that has been viewed as a major threat to our environment is currently gaining attention as valuables resources are being obtained from it. Researchers are now developing nanocomposites/blends from plastic ...
