Pilot exchange programme between UFS and University of Wisconsin
Dionne van Reenen, JC van der Merwe, and Prof John Grider from the University of Wisconsin-Lacrosse.

The Institute for Reconciliation and Social Justice at the University of the Free State (UFS) partnered with the University of Wisconsin-La Crosse in the United States of America (USA) to pilot the first Global Education student-staff exchange. 

The pilot project hosted seven students from the USA and five students from the UFS in a joint tour. The group delved into the political histories of South Africa, visiting among others Freedom Park, the Voortrekker Museum, the Apartheid Museum, and Mandela House during the first leg of the tour in Johannesburg. Before departing from Johannesburg, they had enriching, thought-provoking round-table sessions with Sello Hatang, Leon Wessels, and some of the staff from the Nelson Mandela Foundation.

En route to Pilanesberg in North-West, the tour visited the Sterkfontein Caves and the Cradle of Humankind at Marupeng. Interactive days at the Mphebatho Cultural Museum and Pilanesberg National Park as well as an excursion to Korannaberg to view some San paintings, provided an opportunity to further survey the place of natural, environmental, and cultural heritage in a globalising, modern world.

JC van der Merwe and Dionne van Reenen were joined by Shirley du Plooy and Matau Setshase, together with La Crosse History Chair, Prof John Grider.

Insightful engagements on diverse issues
In Bloemfontein, the lecturing staff facilitated several full-day classes and dialogues at the UFS, after which students offered enlightening presentations on their insights, and showed some serious and deep engagement with legacies of segregation in many different contexts. 

During the closing evening’s discussions with Prof Francis Petersen, UFS Rector and Vice-Chancellor, staff conveyed that, while they usually expect personally transformative moments during such engagements, there is always hope for real critical developments and deepened understandings of how we see and are seen – students on the tour exceeded this hope by seriously grappling with a large array of social and political challenges and initiating lively, inclusive discussions, debating in their own time and spaces.  
“Education, in all its facets, flourished beyond the classroom for staff, students, hosts, and visitors alike, and both institutions look forward to further collaborations in what promises to be a really productive model for international higher-education exchange programmes,” Van der Merwe said.

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.
