Life cycle assessment of facile microwave-assisted zinc oxide (ZnO) nanostructures

Author: Papadaki, D ; Foteinis, S ; Mhlongo, Gugu H ; Nkosi, SS ; Motaung, David E ; Ray, Suprakas S ; Tsoutsos, T ; Kiriakidis, G Date: May 2017 The life cycle assessment of several zinc oxide (ZnO) nanostructures, fabricated by a facile microwave technique, is presented. Key synthesis parameters such as annealing temperature, varied from 90 °C to 220 °C, and microwave power, varied ... Read more
Selective detection of propanol vapour at low operating temperature utilizing ZnO nanostructures

Author: Kortidis, Ioannis ; Lushozi, S ; Leshabane, N ; Nkosi, SS ; Ndwandwe, OM ; Tshilongo, J ; Ntsasa, N ; Motaung, David E Date: Sep 2019 We report on the propanol vapour (C3H8O) gas sensing characteristics of ZnO nanostructures prepared via hydrothermal assisted method. The ZnO-4h sensor showed a high response (i.e. resistance ratio), sensitivity and selectivity toward C3H8O ... Read more
Structural, photoluminescence and XPS properties of Tm3þ ions in ZnO nanostructures

Author: Kabongo, GL ; Mhlongo, Gugu H ; Mothudi, BM ; Hillie, Kenneth T ; Mbule, PS ; Dhlamini, MS Date: Jul 2017 In the present study, a succession of thulium (Tm)-doped zinc oxide (ZnO) nanostructures samples were prepared by sol-gel method using zinc acetate dihydrate, thulium nitrate pentahydrate and sodium hydroxide species with absolute ethanol as ...

Temperature-dependence on the structural, optical, and paramagnetic properties of ZnO nanostructures

Author: Mhlongo, Gugu H ; Motaung, DE ; Nkosi, SS ; Swart, HC ; Malgas, GF ; Hillie, KT ; Mwakikunga, Bonex W Date: Feb 2014 Violet-blue emitting ZnO nanostructures were synthesized by a microwave-assisted hydrothermal method followed by post-synthesis annealing at different temperatures. Scanning electron microscope analysis revealed a morphological transformation ... Read more
