Author:CSIRDate:Jun 2009Energy is a key economic and environmental driver. South Africa, with a large endowment of coal, has an electricity production system that is highly carbon intensive. It generates two-thirds of Africa's electricity, approximately 90% of which ...Read more
Author:Kabongo, GL; Mhlongo, Gugu H; Malwela, T; Mothudi, BM; Hillie, KT; Dhlamini, MSDate:Apr 2014Un-doped and Tb(Sup3+) doped ZnO nanocrystals with different concentrations of Tb(Sup3+) were synthesized by a sol–gel method and their photoluminescence (PL) properties were investigated. The successful incorporation of Tb(sup3+) ions with ...Read more
Author:Kesavan Pillai, Sreejarani; Moloto, N; Ray, SSDate:Feb 2009The organization of metal or semiconductor nanoparticles like quantum dots (QDs) on carbon nanotubes (CNTs) is one good example motivated by the desire to combine the properties of two functional nanoscale materials to achieve a wider range ...Read more
Author:Mbule, PS; Mhlongo, Gugu H; Pitale, SS; Swart, HC; Ntwaeaborwa, OMDate:May 2012In this study, red cathodoluminescence (CL) ( emission=614 nm) was observed from Pr3+ ions in a glassy (amorphous) SiO2 host. This emission was enhanced considerably when ZnO quantum dots (QDs) were incorporated in the SiO2:Pr3+ suggesting ...Read more
Author:Kabwe, KP; Nsibande, SA; Lemmer, Yolandy; Pilcher, LA; Forbes, PBCDate:Nov 2021This work explores the potential use of cadmium-based quantum dots (QDs) coupled to mycolic acids (MAs) as a fluorescent probe to detect anti-MA antibodies which are biomarkers for tuberculosis (TB). The use of free MAs as antigens for the ...Read more
