    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 ...

    Graphite foams were prepared from a coal tar pitch that was partially converted into mesophase. Expandable graphite was used instead of an inert gas to ‘‘foam’’ the pitch. The resulting foam was subjected to a series of ...

    Hydrated filler-type flame retardants were coated with approximately a monolayer of stearic acid using a solvent technique. Compared to the uncoated powders, the BET surface area was lower, the powder packing density was ...
  • Ramjee, Shatish; Rand, Brian; Focke, Walter Wilhelm (Elsevier, 2015-02)
    The low shear rate rheology of two phase mesophase pitches derived from coal tar pitch has been investigated. Particulate quinoline insolubles (QI) stabilised the mesophase spheres against coalescence. Viscosity measurements ...

    The ageing population has become more active and live longer, these patients require hip replacement surgery at a younger age. Artificial hip implants, consisting of the acetabular cup and femoral head, affect the lives ...
  • Hlatshwayo, S.R.; Focke, Walter Wilhelm; Ramjee, Shatish; Rand, Brian; Manyala, Ncholu I. (Elsevier, 2013-01)
    The effect of adding poly(vinyl chloride) (PVC) and coke filler on the rheological behavior and thermal properties of a coal tar pitch was investigated with a view to developing an appropriate viscoelastic binder for the ...

    Pitch material is an important precursor in the production of carbon bre, carbon composites and synthetic graphite. It has a complex transformation during pyrolysis which incorporates the separation of a liquid crystalline ...
