Amplification of the discharge current density of lithium-ion batteries with spinel phase Li(PtAu)0.02Mn1.98O4 nano-materials

Author: Ross, N ; Iwuoha, EI ; Ikpo, CO ; Baker, P ; Njomo, N ; Mailu, SN ; Masikini, M ; Matinise, N ; Tsegaye, A ; Mayedwa, N ; Waryo, T ; Ozoemena, KI ; Williams, A Date: May 2014 In this study the synergistic and catalytic properties of a novel nano-composite cathode material of nominal composition Li(M)(subx)Mn(sub2-x)O(sub4) (M = Pt-Au; x # 0.2) has been explored. Li(PtAu)xMn(sub2-x)O4 nanomaterial for use in ... Read more
The effect of Co and In combinational or individual doping on the structural, optical and selective sensing properties of ZnO nanoparticles

Author: Maswanganye, MW ; Rammutla, KE ; Mosuanga, TE ; Mwakikunga, Bonex W Date: Aug 2017 Variably doped ZnO samples by the sol-gel process have been tested for response to humidity and industrial gases of CO, CH(sub4), NH(sub3) and H9sub2). The elements of Cobalt (Co) and Indium (In) either singly doped or co-doped at 5 wt% and ... Read more
Electrically active, doped monocrystalline silicon nanoparticles produced by hot wire thermal catalytic pyrolysis

Author: Scriba, Manfred R ; Britton, DT ; Härting, M Date: May 2011 Doped silicon nanoparticles have successfully been produced by hot wire thermal catalytic pyrolysis at 40 mbar and a filament temperature of 1800 °C, using a mixture of silane and diborane or phosphine. All particles are monocrystalline with ... Read more
Influence of Co doping on physiochemical properties of MnFe2O4/C nano compounds toward oxygen reduction reaction

Author: Matseke, Mphoma, S ; Zheng, Haitao ; Mathe, Mkhulu K ; Carleschi, E ; Doyle, B Date: Dec 2021 Recently, several researchers have found that the manganese ferrite (MnFe2O4) nanoparticle can be a promising candidate for the oxygen reduction reaction (ORR). However, the MnFe2O4 nanoparticles still face challenges on their ORR activity ... Read more
Transition metal alloy-modulated lithium manganese oxide nanosystem for energy storage in lithium-ion battery cathodes

Author: West, N ; Ozoemena, KI ; Ikpo, CO ; Baker, PGL ; Iwuoha, EI Date: Jul 2013 This paper explores the synergistic and catalytic properties of a newly developed lithium ion battery (LIB) composite cathode of LiMn(sub2)O(Sub4) modified with bimetallic (Au–Fe) nanoparticle. Spinel phase LiMn(sub)2O(sub4) was doped with ... Read more
