    Graphene based nano-coatings: synthesis and physical-chemical investigations 

    Nyangiwe, Nangamso Nathaniel (UWC, 2012)
    It is well known that a lead pencil is made of graphite, a naturally form of carbon, this is important but not very exciting. The exciting part is that graphite contains stacked layers of graphene and each and every layer ...

    Multilayer graphene modified metal film electrodes for the determination of trace metals by anodic stripping voltammetry 

    Zbeda, Salma Gumaa Amar (2013)
    In this study multilayer graphene nanosheets was synthesize by oxidizing graphite to graphene oxide using H2SO4 and KMnO4 followed by reduction of graphene oxide to graphene using NaBH4. The graphene nanosheets were ...

    Nanocomposite-graphene based platform for heavy metal detection 

    Willemse, Chandre Monique (University of the Western Cape, 2010)
    This study reports the synthesis of graphene by oxidizing graphite to graphite oxide using H2SO4 and KMnO4 and reducing graphene oxide to graphene by using NaBH4. Graphene was then characterized using FT-IR, TEM, AFM, XRD, ...

    Microfluidic graphenised-paper electroanalytical devices (μGPED) for adsorptive cathodic stripping voltammetric detection of metal contaminants 

    Pokpas, Keagan William (University of the Western Cape, 2017)
    The need for clean, non-toxic drinking water supplies, free of pollutants and metal contamination is vital in impoverished areas and the developing world alike. With this in mind, the development of accurate, inexpensive, ...

    The design of ultrasensitive immunosensors based on a new multi-signal amplification gold nanoparticles-dotted 4-nitrophenylazo functionalised graphene sensing platform for the determination of deoxynivalenol 

    Sunday, Christopher Edozie (University of Western Cape, 2014)
    A highly dispersive gold nanoparticle-dotted 4-nitrophenylazo functionalised graphene nanocomposite (AuNp/G/PhNO2) was successfully synthesised and applied in enhancing sensing platform signals. Three label-free ...
