Application of membrane technology in a base metal refinery
(SAIMM, 2013)Nanofiltration (NF) has attracted much attention over the past few years due to the reduced energy consumption compared to reverse osmosis (RO) and better separation performance compared to ultrafiltration (UF). Although ... -
Chitosan: a low cost material for the production of membrane for use in PEMFC – a review
(Taylor & Francis, 2013)Fuel cells, especially proton exchange membrane fuel cells, are considered promising and an attractive replacement for existing sources of energy. Despite the high potential of proton exchange membrane fuel cells as an ... -
A comparative study of the processing scheme of chitosan and Nafion 117 in membrane electrode assembly
(Taylor & Francis, 2013)The authors considered two fabrication techniques in the fabrication of the membrane electrode assembly. It was observed that catalytic deposition through electro-spraying was not successful for chitosan and Nafion 117 ... -
Development and testing of an anion exchange membrane electrolyser
(Elsevier, 2015)In the context of energy policy and the use of renewable energies, our research institute collaborates with other partners on the development of a compact, environmental-friendly and effective electrolyser for efficient ... -
Development of a compact, passive helium purification system for the advanced high temperature reactor
(North-West University (South Africa), 2020)In this study the possibility of a compact, passive membrane system to separate helium from the impurities that may be present in the AHTR primary system was investigated. The current helium purification systems that are ... -
Stability of acid-excess acid-base blend membranes in all-vanadium redox-flow batteries
(Elsevier, 2015)In this contribution the performance of two acid–base blend membranes in an all-vanadium redox-flow battery (VRFB) is studied. The first membrane is a nonfluorinated acid–base blend membrane composed of a sulfonated ...
