The Office for International Affairs (OIA) at the University of the Free State (UFS) implemented the second iteration of its Umoja Buddy Programme (UBP) in 2020. The UBP is a flagship internationalisation-at-home programme aimed at the smooth academic, social, and cultural integration of first-entering international students at the UFS by pairing them with senior UFS students. It offers local students an international experience on the home campus and develops their international and intercultural competence through direct interaction with international students. The UBP contributes to the achievement of the UFS vision, whereby every student will in future have an international experience during their studies at the UFS.


Internationalisation at home

On 13 February 2020, a welcome function themed Echoes of Sophiatown set the tone for this year’s edition. Chevon Slambee, Chief Officer in the OIA and UFS master’s student, welcomed the students and explained the theme of the day. She said that, “as students, we have a responsibility to be active citizens and contribute to change and social transformation”. Programme coordinator Bulelwa Moikwatlhai introduced the function and framework of the programme and highlighted the importance of internationalisation at home. Also in attendance was the Dean of Students, Pura Mgolombane, who encouraged students in his address to honour their heritage, “so that together, we can be able to appreciate one another”. He emphasised the importance of social justice for academic success. The SRC member for the International Student Council, Simba Matheba, expressed his support for the UBP. The UFS Arts, Culture, and Dialogue office provided entertainment at the event.

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.
