Development of Proton Exchange Membrane (PEM) for Telecom fuel cell applications

Abdulkareem, A.S.; Afolabi, A.S.; Idibie, C.A.; Iyuke, S.E. (Southern Africa Telecommunication Networks and Applications Conference, 2009-09-20)

The high cost of fuel cells compared to other energy sources creates uncertainty about the projected full scale commercialization of this device. This paper describes the synthesis of a proton exchange membrane from the ...
Effect of tempering temperature and time on the corrosion behaviour of 304 and 316 austenitic stainless steels in oxalic acid

Afolabi, A.S.; Potgieter, J.H.; Abdulkareem, A.S.; Fungura, N. (2011)

The effect of different tempering temperatures and heat treatment times on the corrosion resistance of austenitic stainless steels in oxalic acid was studied in this work using conventional weight loss and electrochemical ...
Optimizing carbon nanotube continuous production in a swirled floating catalyst chemical vapour deposition reactor

Iyuke, S.E.; Pienaar, H.C. vZ.; Abdulkareem, A.S.; Afolabi, A.S. (South African Chemical Engineering Congress, 2006-09-20)

Effects of various factors affecting the rate of Carbon Nanotubes (CNTs) produced in a Swirled Floating Catalyst Chemical Vapour Deposition (SFCCVD) reactor were investigated. This study was performed in a vertical silica ...
Synthesis and purification of bimetallic catalysed carbon nanotubes in a horizontal CVD reactor

Afolabiac, A.S.; Abdulkareem, A.S.; Mhlang, S.D.; Iyuke, S.E. (2011)

Carbon nanotubes (CNTs) were synthesised by a conventional chemical vapour deposition (CVD) method using acetylene as carbon source and a bimetallic catalyst of Fe-Co supported on a CaCO3 support. The CNTs were characterized ...
