All academic activities on the campuses of the University of the Free State (UFS) will resume face-to-face on Monday 7 August 2023.

This decision by the university’s executive management comes after campus-wide protests on 2 August 2023, and the subsequent decision to continue the academic programme online until 4 August 2023.

The university can confirm that a large number of UFS-registered students funded by the National Student Financial Aid Scheme (NSFAS) who have been excluded from payment, have received their allowances on Friday 4 August 2023. The university is aware that a small number of students have not yet onboarded successfully with eZaga – an online digital banking service tasked with disbursing direct payments to NSFAS beneficiaries. These students have been requested to urgently onboard successfully with eZaga in order to receive their allowances.

On a sectoral level, the university would also like to confirm that a statement has been issued by Universities South Africa (USAf) in which NSFAS and the Department of Higher Education, Science and Innovation are, among others, requested to urgently resolve the matter of the direct payment of allowances to students. The UFS fully supports the statement and is hopeful that an amicable and urgent solution to the matter can be found.

Protection Services and the South African Police Service remain on high alert and are monitoring the situation on the campuses closely. The necessary security measures are in place to ensure the safety of students and staff.

Prof Francis Petersen, Vice-Chancellor and Principal, will address our staff and students on 8 August 2023 about last week’s protest action. Please monitor the communication platforms for more information on this important engagement session.

message from Prof Francis Petersen, Vice-Chancellor and Principal, to staff and students about last week’s protest was also shared on 3 August 2023.

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.
