Author:Malwela, Thomas; Khumalo, VM; Salehiyan, Reza; Ray, Suprakas SDate:Jul 2018The influences of surface treatment and the concentration of boehmite alumina (BA) particles on polypropylene and polystyrene (PS) (80/20) blends produced via melt compounding were examined. The results show that p-toluene sulfonic acid-treated ...Read more
Author:Thabethe, S; Arendse, CJ; Mwakikunga, Bonex WDate:Dec 2014Advanced core–shell FeSi@SiO(subx) nanowires are observed when FeCl(sub3) vapour is made to flow over a SiO(sub2)/Si substrate at 1100 degress C. The thickness of the SiO(subx) sheath (d0) is found to depend inversely as the period of time ...Read more
Author:Kesavan Pillai, Sreejarani; Ray, SS; Scriba, Manfred R; Ojijo, Vincent O; Hato, MJDate:Jul 2013Biocomposites containing ultraviolet (UV) radiation absorbing inorganic nanofillers are of great interest in food packaging applications. The biodegradable polylactide (PLA) composite films were prepared by solvent casting method by incorporating ...Read more
Author:Motloung, Mpho P; Ojijo, Vincent O; Sinha Roy, JayitaDate:Nov 2019This work investigates the effect of cellulose nanocrystal (CN) loading on the properties of polylactide/poly(e-caprolactone) (PLA/PCL) (70/30) blend processed in a twin-screw extruder as a potential material that can be utilized in various ...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
Author:Mwakikunga, Bonex W; Malwela, T; Hillie, T; Ndlovu, GDate:Oct 2011Traditional gas sensors involve heating the sensor material for gas selectivity. New gas approaches require activation by a broadband UV light source. The authors propose to employ a tuneable UV source in which this source is tuned for its ...Read more
