Antiferromagnetic–paramagnetic state transition of NiO synthesized by pulsed laser deposition

Author: Nkosi, SS ; Yalisi, B ; Motaung, DE ; Keartland, J ; Sideras-Haddad, E ; Forbes, A ; Mwakikunga, Bonex W Date: Jan 2013 Thin films of nickel oxide (NiO) were deposited on Al substrates at different substrate temperatures using pulsed laser deposition (PLD). Microwave power absorption measurements at 9.4 GHz (X-band) were carried out on these PLD grown films. ... Read more
Colour tuning from violet to blue emission stimulated by various nickel oxide nanostructures: Influence of bias voltage towards volatile organic compounds vapours

Author: Mokoena, Teboho P ; Swart, HC ; Hillie, Kenneth T ; Motaung, DE Date: Mar 2021 Propanol and benzene, toluene, ethylenebenzene and xylene (BTEX) vapours are within the volatile organic compounds (VOCs) family and are utilized in industrial and petroleum goods, are greatly toxic in human health and environment. Therefore, ... Read more
Influence of mesoporous defect induced mixed-valent NiO(Ni2+/Ni3+)-TiO2 nanocomposite for non-enzymatic glucose biosensors

Author: Rajendren, S ; Manoj, D ; Raju, Kumar ; Dionysiou, DD ; Naushad, M ; Gracia, F ; Cornejo, L ; Gracia-Pinilla, MA ; Ahamad, T Date: Jul 2018 An extraordinary sensitive and selective non-enzymatic glucose sensor has been demonstrated based on the electrochemically highly stable NiO-TiO2 mixed oxide comprising the defect induced mesoporous TiO2 nanoparticles with Ni2+ and Ni3+ ions ...
