Diffusion of Co and W in diamond tool induced by 10.6 µm CO2 laser radiation

Author: Masina, Bathusile N ; Forbes, Andrew ; Mwakikunga, Bonex W ; Bodkin, R Date: May 2011 At present it is known that diamond tools degrade with time as it is normally used at high temperatures. One of the questions the authors like to answer in this study is whether thermally induced problems in diamond tool arise as a result of ... 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
Formation, surface characterization, and electrocatalytic application of self-assembled monolayer films of tetra-substituted manganese, iron, and cobalt benzylthio phthalocyanine complexes

Author: Akinbulu, IA ; Ozoemena, KI ; Nyokong, T Date: Oct 2011 Molecular thin films of manganese (SAM-2), iron (SAM-3), and cobalt (SAM-4) phthalocyanine complexes, non-peripherally tetra-substituted with benzylmercapto, were formed on polycrystalline gold disc electrode by selfassembly technique. Surface ... 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
Reinvestigation of the structures of lithium-cobalt-oxides with neutron-diffraction data

Author: Gummow, RJ ; Liles, DC ; Thackeray, MM ; David, WIF Date: Nov 1993 The structures of LT-LiCoO2 (synthesised by reaction of Li2CO3 and CoCO3 at 400-degrees-C) and its delithiated product LT-Li0.4CoO2 have been reinvestigated by neutron powder diffraction. Despite an unusually close similarity between diffraction ... Read more
Spinel versus layered structures for lithium cobalt oxide synthesized at 400-degrees-c

Author: Gummow, RJ ; Liles, DC ; Thackeray, MM Date: Mar 1993 Rietveld refinements of X-ray data of LiCoO2 prepared at 400-degrees-C and a chemically-delithiated product Li0.5CoO2 using space group symmetries R3mBAR and Fd3m are reported. Refinements in both R3mBAR (layered-type structure) and Fd3m ... Read more
