The University of the Free State (UFS) recently welcomed senior members from the International Centre for Medical Research in Franceville (CIRMF), Gabon to sign a Memorandum of Understanding (MoU) between the two entities.
CIRMF is a non-profit medical research centre that was established in 1974. Its primary focus is on diagnosing infectious diseases that pose immediate problems in Gabon and the Central African sub-region. The centre is dedicated to improving public health through various initiatives, including the training of Gabonese health executives in doctoral and post-doctoral education.
“The signing of the MoU with CIRMF is a step in the right direction as the UFS continues to strengthen its footprint on the African Continent. This is seminal in driving the university’s internationalisation processes and opening an avenue to expanding research networks, especially in the African continent,” said Bonolo Makhalemele, Coordinator of strategic projects at the Office for International Affairs, UFS.
In the interest of developing broader research collaborations, the CIRMF delegation met with some UFS academics in a series of engagements, particularly in the Health Sciences Faculty and the Natural and Agricultural Sciences Faculty. “The integration of knowledge and practices that emanate from the continent provides opportunities for the co-creation of knowledge that can be shared with the rest of the world,” said Kagiso Ngake, Coordinator for Partnerships, Collaborative Degrees, and Outgoing Mobility at the Office for International Affairs, UFS.
A concrete roadmap was established to formalise the collaborations that resulted from these engagements and will commence as soon as April 2023. “We have laid a solid foundation and are on the way to a strong and rich partnership!” exclaimed Prof Jean Bernard Lekana-Douki, Director General at the CIRMF.
Prof Francis Petersen, Rector, and Vice-Chancellor of the UFS, further highlighted how the newly established partnership with the CIRMF aligns with the mandate of the UFS Vision 130 of expanding the UFS Africa research network.
Prof Tredoux turns theories regarding the formation of metals on its head

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.
The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.
This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.
Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.
The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.
For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.
“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”
Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
