The management of the University of the Free State (UFS) is deeply concerned about the continued xenophobic and Afrophobic attacks in our country, specifically the actions of, and statements made by groups and individuals. 

The UFS condemns all forms of xenophobic and Afrophobic actions and thinking and expresses its solidarity with the members of the university community hailing from other regions of the African continent and the world. The UFS is committed to promoting diversity, social justice, inclusivity, and transformation and is united in its diversity. As a university community, it cherishes diversity as a catalyst for positive change, innovative research, and cutting-edge teaching and learning. Xenophobic actions, threats, or statements will not be tolerated at the UFS. The UFS is committed to nurturing and entrenching a human-rights culture and advocating human rights, both within the context of the university and beyond.

Xenophobia, Afrophobia, and discrimination jeopardise the process of internationalisation at any university. It limits the international and multicultural exposure of our students, which is important to achieve graduate attributes and to specifically develop students’ international and intercultural competence. The UFS is strategically strengthening its collaborations and partnerships in Africa and beyond. It recognises the positive power of diversifying the knowledge paradigms with which it interacts. International staff members, postdoctoral fellows, and students make a significant contribution to the academic project, scholarship traditions, and intellectual diversity of the university. 

The management of the UFS will do everything in its power to ensure the well-being of all members of its international university community.

Xenophobia is the ‘fear and hatred of strangers or foreigners or of anything that is strange or foreign’ (Merriam-Webster Dictionary), whereas Afrophobia can be understood as the ‘fear and hatred of the cultures and people of Africa’.

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.
