Ghanaian contemporary artist, Ibrahim Mahama, visited the Department of Fine Arts at the University of the Free State (UFS) to share insights with staff and students during his stay in the country.
Dr Adelheid Von Maltitz, Senior Lecturer in the Department of Fine Arts at the UFS, highlighted the significance of Mahama’s visit which took place from 21 to 28 March 2024, marking the first instance of such interaction between a Fine Arts department in South Africa and Mahama. She remarked, “It is truly astounding that a person of his calibre dedicated time to focus on our department, and I believe this has catalysed a positive shift within our department.”
Mahama’s impactful presence at UFS
Dr Von Maltitz emphasised that Mahama’s visit aimed to offer staff and students a glimpse into his artistic process and mindset. During his time at the UFS, Mahama, who was virtually overseeing his latest recent large-scale artwork titled Purple Hibiscus, which involved wrapping the Barbican Centre in London, engaged extensively with staff and students from the department about their research. He shared insights into his creative journey, presented select works, and conducted critique sessions with fourth year and postgraduate students, among other activities. Dr Von Maltitz believes this interaction, particularly with students, has significantly bolstered their confidence as aspiring artists, preparing them for professional endeavours.
Broader implications and future prospects
Mahama’s visit not only energised the department’s academic environment but also holds broader implications. Dr Von Maltitz asserted that it will solidify the department’s identity nationally and create avenues for students to pursue residencies in countries like Ghana. Therefore, maintaining a fruitful relationship with Mahama remains a priority for the department.
Reflecting on the visit Dr Von Maltitz concluded, ‘’the key takeaway, especially for the students, was witnessing the potential of their works within the broader South African and international contexts. “
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.
