Effect of the annealing atmosphere on the layer interdiffusion in Pd/Ti/Pd multilayer stacks deposited on pure Ti and Ti-alloy substrates
Halindintwali, Sylvain; Donald, Earl; Cummings, Franscious; Arendse, Christopher (University of the Western Cape, 2019)Pd(50 nm)/Ti(25 nm)/Pd(50 nm) multilayer stack has been deposited on Ti and Ti6Al4V substrates; we have studied the intermixing of layers upon annealing at the hydrogenation temperature of 550 °C, under vacuum, H/Ar gas ... -
A highly responsive nh3 sensor based on pd-loaded zno nanoparticles prepared via a chemical precipitation approach
Cummings, Franscious (ScienceDirect, 2019)The gas-detecting ability of nanostructured ZnO has led to significant attention being paid to the development of a unique and effective approach to its synthesis. However, its poor sensitivity, cross-sensitivity to humidity, ... -
Opto-electronic properties of anodized TiO2 nanotube arrays investigated using electron energy loss spectroscopy
Cummings, Franscious (sciencedirect, 2019)A study of the nanoscale crystallinity of anodized TiO2 nanotubes is reported with the aim of demonstrating its influence on the localized optical and electronic properties of the structure. By employing scanning transmission ...
