    • Amplification of the discharge current density of lithium-ion batterieswith spinel phase Li(PtAu)0.02Mn1.98O4nano-materials 

      Mailu, Stephen N.; Iwuoha, Emmanuel I.; Ikpo, Chinwe O.; Baker, Priscilla; Njomo, Njagi; Masikini, Milua; Matinise, Nolubabalo; Tsegaye, Abebaw; Mayedwa, Noluthando; Waryo, Tesfaye; Ozoemenab, Kenneth I.; Williams, Avril (Elsevier, 2014)
      In this study the synergistic and catalytic properties of a novel nano-composite cathode material ofnominal composition Li(M)xMn2-xO4(M = Pt-Au; x # 0.2) has been explored. Li(PtAu)xMn2-xO4nano-material for use in lithium-ion ...

    • Electronics of Conjugated Polymers (I): Polyaniline 

      Molapo, Kerileng M.; Ndangili, Peter M.; Ajayi, Rachel F.; Mbambisa, Gcineka; Mailu, Stephen M.; Njomo, Njagi; Masikini, Milua; Baker, Priscilla; Iwuoha, Emmanuel I. (International Journal of ELECTROCHEMICAL SCIENCE, 2012-12)
      Conducting polymers have elicited much interest among researchers because of their reasonably good conductivity, stability, ease of preparation, affordability and redox properties compared to other organic compounds. In ...

    • A Fumonisins Immunosensor Based on Polyanilino-Carbon Nanotubes Doped with Palladium Telluride Quantum Dots 

      Masikini, Milua; Mailu, Stephen N.; Tsegaye, Abebaw; Njomo, Njagi; Molapo, Kerileng M.; Ikpo, Chinwe O.; Sunday, Christopher E.; Rassie, Candice; Wilson, Lindsay; Baker, Priscilla G. L.; Iwuoha, Emmanuel I. (2014-12-24)
      An impedimetric immunosensor for fumonisins was developed based on poly(2,5-dimethoxyaniline)-multi-wall carbon nanotubes doped with palladium telluride quantum dots onto a glassy carbon surface. The composite was assembled ...

    • Graphenated tantalum (IV) oxide and poly (4-styrene sulphonic acid)-doped polyaniline nanocomposite as cathode material in an electrochemical capacitor
