University of the Free State students participating in one of the many projects coordinated by the Engaged Scholarship Office.
To help make a change and push for sustainable development, the University of the Free State Division of Student Affairs works with communities around Bloemfontein fostering a culture of creating sustainable solutions.
Gernus Terblanche, Kovsie Support Services and Assistant Researcher in the Division says, ‘it is important for the university to be actively involved in the community as it makes up such a large portion of the Bloemfontein and students also
represent many different communities on and off- campus.’
Terblanche said: “As an educational institution it is vital for the UFS to support and guide students towards creating innovative solutions; both local and globally. Our experience is that students often come up with real solutions that can
make a real impact in the lives of real people – and it would be crucial to support such initiatives.”
The office has worked with BloemShelter, VermiVillage, GAP Equip, National Hospital and as part of the programmes of 2022 also with Lighuis, Talita Cumi, ROC Kids and the Universitas Neighborhood association. “We are also very fortunate to have,
Shanen Emam, Miss Free State 2023 as one of our students that are involved with our programmes,” added Terblanche.
One of the students involved is Prince Sijane, Bloemfontein Campus Student Representative Council member responsible for Civic and Social Responsibility when asked why student participation is important, he said, “By actively participating in
initiatives that address social issues or promote community well-being, students become more aware of the challenges faced by society.”
Tereblanche said: “The produce of these gardens addresses hunger and malnutrition amongst students on campus. KovsieACT also facilitates an eco-vehicle project during which student teams learn how to build electric vehicles powered by solar charging
stations. This project is aimed at developing skills appropriate to the 4th Industrial Revolution and sustainable resources development including clean and green energy.”
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.
