Staff, students and other stakeholders of the University of the Free State (UFS) can look forward to a virtual music show honouring the values and beliefs of former President Nelson Mandela. Musicians such as Simple Stories, Sibongile Mngoma, Boitumelo Mohutsioa, and Lucy Sehloho have prepared performances that will be showcased on UFS communication platforms on 31 July. Concluding Mandela Month celebrations, the pre-recorded show will also feature performances by poets Braithan Moratwa and Zilungile Muqayi. The show is coordinated by the Division of Student Affairs at the UFS.  

Angelo Mockie, Senior Officer: Arts, Culture and Dialogue at Student Affairs, says the show was primarily produced to convey a message of hope, solidarity, and support to the UFS community. “We chose Mandela Month to publish it, because those are the values that he believed in. Now more than ever, we need to stand together as a community to find ways of adapting to the new normal.”

In a message to UFS staff acknowledging the life and legacy of Nelson Mandela, Prof Francis Petersen, Rector and Vice-Chancellor, said Madiba’s example of compassion and courage made him one of the best-known leaders in the world.
“His life was a true inspiration and his devotion to democracy, equality, learning, and caring for others have earned him the respect of communities around the world.

This year, the significance of Mandela Day will be even more important than ever before, as we demonstrate caring by looking after ourselves, our families, and those around us, while we navigate through the pandemic. Caring provides purpose, but also the motivation to fulfil that purpose. The COVID-19 pandemic should enable us to imagine a world that is fairer, safer, more stable, secure, and one that can prosper.”

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.
