The composition of the UFS Council is stipulated in the UFS Statute, which was published in the Government Gazette on 10 March 2023. The Convocation has to elect two (2) external Convocation members (who are neither employees nor students of the UFS) to the Council, as required by the Statute of the UFS. The elected members will serve on the Council for a period of four years.

The Convocation comprises all persons who obtained a formal qualification from the UFS, as well as all permanent and retired academic staff members.

Members of the Convocation are invited to submit written nominations by using the Nomination Form attached hereto.

Every nomination form must be signed by 2 (two) members of the Convocation and must contain the written acceptance of the nomination by the nominee under his/her signature, as well as an abridged CV and a motivation of ± 200 words.

All nominations must reach the office of the Registrar no later than 4 October  2024.

If more than two persons are nominated, an election will be held as stipulated in the Interim Institutional Rules. More information regarding this process will follow at that stage. 

Nominations are to be submitted to:
     e-mail: registrar@ufs.ac.za

or hand-delivered to:
     Mr NN Ntsababa
     Room 51 
     1st Floor
     Main Building
     UFS Bloemfontein Campus

For any enquiries, please contact Mr NN Ntsababa at registrar@ufs.ac.za or +27 51 401 3796.

Kindly take note that late or incomplete nominations will not be accepted or considered.

Each nomination must be submitted separately.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

17 September 2013

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.
