Due to the seriousness of the global COVID-19 outbreak, the Rector and Vice-Chancellor, Prof Francis Petersen, established a Coronavirus Task Team comprising representatives from various key function areas on the University of the Free State (UFS) campuses. This includes members of the executive management, virologists, infectious disease experts, and representatives of the academic and support-service functions. The team meets frequently to discuss the contingency and preparedness plans for the university’s three campuses. 

In response to the current pandemic, the UFS has opted to postpone all graduation and related prize-giving ceremonies scheduled to take place from 20 to 24 April 2020 and 10 to 12 June 2020 on the Bloemfontein Campus,  as well as those from 8 to 9 May 2020 on the Qwaqwa Campus. We know that this was the best decision to curb the spread of the disease as far as possible.

The university acknowledges the importance of graduation ceremonies and appreciates the diligence displayed by our students. We also recognise the virtual graduation ceremonies held by other institutions to confer and award qualifications. As such, a survey was issued to the April, May, and June 2020 graduates to determine their preference between virtual and traditional ceremonies.  

We are grateful for the response to the survey, which indicated that the overwhelming majority of graduates prefer a traditional graduation ceremony. The university’s executive management subsequently resolved that a final decision regarding virtual or traditional ceremonies would be made towards the end of July or the beginning of August 2020. The university still hopes to host the graduation ceremonies on its campuses in 2020 so that we can celebrate this joyous occasion with our graduates and their families. We will continue to evaluate the decision in light of the developments related to COVID-19, as well as taking into account the national lockdown level at the time. 

We will continue to support and assist students who require confirmation of their qualification and academic records for either employment or to further their studies.  Please contact us at 051 401 9666 or studentadmin@ufs.ac.za for any enquiries about the graduation ceremonies.

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.
