Author:Oliphant, CJ; Arendse, CJ; Camagu, ST; Swart, HDate:Feb 2014Filament condition during hot-wire chemical vapor deposition conditions of multi-walled carbon nanotubes is a major concern for a stable deposition process. We report on the novel application of electron backscatter diffraction to characterize ...Read more
Author:Malgas, GF; Arendse, CJ; Cele, NP; Cummings, FRDate:Feb 2008This paper reports on the growth of carbon nanotubes (CNTs) by thermal Chemical Vapour Deposition (CVD) and investigates the effects of nitrogen carrier gas flow rates and mixture ratios on the morphology of CNTs on a silicon substrate by ...Read more
Author:Mwakikunga, Bonex WDate:2014This review outlines, in great detail, the history of the phenomenon of ultrasonic nebulization of liquids since the discovery of such an effect by Michael Faraday and the explanation of the phenomenon by capillary wave mechanism and “cavitation” ...Read more
Author:Thabethe, BS; Malgas, GF; Motaung, DE; Malwela, T; Arendse, CJDate:Jan 2013The authors report on the synthesis of tin oxide (SnO(sub2)) nanowires by a chemical vapor deposition (CVD) process. Commercially bought SnO nanopowders were vaporized at 1050°C for 30 minutes with argon gas continuously passing through the ...Read more
