  • Patent number: 9269981
    Abstract: This invention relates to fuel cells, particularly proton exchange membrane fuel cells, more particularly to proton exchange membrane fuel cells employing nanocomposite sulphonated polystyrene-butadiene rubber-carbon nanoball (SPSBR-CNB) membranes as an electrolyte.
    Type: Grant
    Filed: June 22, 2010
    Date of Patent: February 23, 2016
    Assignee: University of the Witwatersrand
    Inventors: Sunny Esayegbemu Iyuke, Hendrik Christoffel Van Zyl Pienaar, Ambali Saka Abdulkareem, Ayo Samuel Afolabi, Christopher Avwoghokoghene Idibie
  • Patent number: 9102525
    Abstract: The invention provides a process for producing carbon nanotubes which includes supplying a continuous fluidized feed of a catalyst and at least one hydrocarbon to a reactor operating under conditions suitable to produce carbon nanotubes. The fluid is made to flow though the reactor with a swirling motion which ensures that the internal surfaces of the reactor are cleaned of deposits.

  • Publication number: 20120064142
    Abstract: This invention relates to a polymeric pharmaceutical dosage form for the delivery, in use, of at least one pharmaceutical composition in a rate-modulated and site-specific manner. The dosage form comprises a biodegradable, polymeric, scaffold incorporating loaded with at least one active pharmaceutical ingredient (API). The polymer or polymers making up the scaffold degrade in a human or animal body in response to or in the absence of specific biological stimuli and, on degradation, release the API or APIs in an area where said stimuli are encountered. Preferably the polymeric scaffold is formed from poly (D1L-lactide) (PLA) and polymethacrylate (Eudragit S100/ES100) polymers.
