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 ... -
Determination of Anthracene on Ag-Au Alloy Nanoparticles/Overoxidized-Polypyrrole Composite Modified Glassy Carbon Electrodes
Mailu, Stephen N.; Waryo, Tesfaye T.; Ndangili, Peter M.; Ngece, Fanelwa R.; Baleg, Abd A.; Baker, Priscilla G.; Iwuoha, Emmanuel I. (Molecular Diversity Preservation International, 2010)A novel electrochemical sensor for the detection of anthracene was prepared by modifying a glassy carbon electrode (GCE) with over-oxidized polypyrrole (PPyox) and Ag-Au (1:3) bimetallic nanoparticles (Ag-AuNPs). The ... -
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 ... -
Impedimetric Response of a Label-Free Genosensor Prepared on a 3-Mercaptopropionic Acid Capped Gallium Selenide NanocrystalModified Gold Electrode
Ndangili, Peter M.; Jijana, Abongile N.; Olowu, Rasaq A.; Mailu, Stephen N.; Ngece, Fanelwa R.; Williams, Avril; Waryo, Tesfaye T.; Baker, Priscilla G.L.; Iwuoha, Emmanuel I. (2011)Biocompatible and water soluble 3-mercaptopropionic acid cappedgallium selenide nanocrystals were synthesized from hydrated gallium (III) perchlorate and selenide ions. The nanocrystals were non-fluorescent but ... -
In - situ Electrochemical Synthesis, Microscopic and Spectroscopic Characterisations of Electroactive poly(2,5-dimethoxyaniline) – Multi-Walled Carbon Nanotubes Composite Films in Neutral Media
Masikini, Milua; Mailu, Stephen N.; Tsegaye, Abebaw; Ikpo, Chinwe O.; Njomo, NJagi; Waryo, Tesfaye T.; Baker, Priscilla G. L.; Iwuoha, Emmanuel I. (International Journal of ELECTROCHEMICAL SCIENCE, 2014-09-29)Poly(2,5- dimethoxyaniline)-multi-wall carbon nanotubes (PDMA-MWCNT) nanocomposite films were synthesised by in –situ electrochemical polymerisation. The films were characterised by cyclic voltammetry (CV), ultra–visible ...
