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 ...
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 ...
