Characteristics of point defects on the room temperature ferromagnetic and highly NO2 selectivity gas sensing of p-type Mn3O4 nanorods

Author: Kortidis, Ioannis ; Swart, HC ; Ray, Suprakas S ; Motaung, David E Date: Apr 2019 This study investigates the room temperature (RT) gas-sensing and ferromagnetic behavior of p-type materials based on a comparison of NiO, Mn3O4, and CuO nanostructures prepared using a hydrothermal method. The Mn3O4 nanorods based sensor ... Read more
Detailed understanding on the relation of various pH and synthesis reaction times towards a prominent low temperature H2S gas sensor based on ZnO nanoplatelets

Author: Kortidis, Ioannis ; Swart, HC ; Ray, Suprakas S ; Motaung, David E Date: Mar 2019 An unceasing scientific challenge to monitor the emissions of toxic and flammable gases in a selective approach is of great importance for safety of human health. As a result, herein, we report on the detailed study of the gas sensing ... 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
Structure-property relationship of the laser cladded medium carbon steel: The use of butter layer between the substrate and the top clad layer

Author: Botes, Annelize ; Bolokang, Amogelang S ; Kortidis, Ioannis ; Matjeke, V Date: Mar 2019 The structure-property relationship of the laser deposited 316 L/St 1.2311 and Fe/St 1.2311 on E9 substrate was investigated. The variation in the geometrical features of the deposited layers, width, thickness, depth of penetration into the ... Read more
