MERG at WITS invests in a Bio-Logic impedance analyser coupled with a high temperature furnace for materials and analysis
Members of the Materials for Energy Research Group (MERG) at the University of the Witwatersrand (from both Schools of Chemistry and Physics) recently purchased a MTZ-35 Impedance Analyser with High Temperature Furnace and a VMP300 Multichannel Potentistat/Galvanostat with Electrochemical Impedance Spectrometry from Bio-Logic. These will be used to study various types of energy materials.
The high temperature measurements (up to 1 100°C with this system) will be used to study predominantly mixed metal oxides for possible application in solid oxide fuel cells. At this stage Biologic is the only complete commercially available setup that can readily do high temperature measurements. The ambient temperature work will be based around a range of materials, with one of the focus areas including thin films with possible application in photovoltaics.
