The registration process for senior students at the University of the Free State (UFS) is well underway; for the first time in the history of the university, students can only register online this year. Online registration and orientation for senior undergraduate and postgraduate students started on 8 February 2021 and will conclude on 26 February 2021. For first-year students, online registration and orientation will take place from 1 to 13 March 2021.


“At the end of 2020, the UFS was one of the few universities in the country that was able to complete its academic year in December. This is indeed an achievement to be extremely proud of. 2021 will be a year like no other for our students and staff. Apart from the normal activities on our campuses at the beginning of an academic year, we are following a minimalistic approach to the return of staff and students during the first semester, as our country is still in lockdown. It is also important to keep our staff and students safe,” says Prof Francis Petersen, Rector and Vice-Chancellor of the UFS. 

During the first semester, the UFS will continue with an online/blended learning and teaching approach for first-year and senior undergraduate students. This means that some classes will be online, some in contact or face-to-face mode, and others a combination of contact and online. “The COVID-19 pandemic has resulted in a global shift towards the integration of technology into learning and teaching, which the university is embracing this year,” says Prof Petersen. 

Due to the national lockdown regulations and the capacity of the university’s infrastructure to adhere to physical distancing protocols, the UFS is limiting the number of students who will be returning to the campuses next month. Students will be contacted by their faculties if they are required to return to the campuses. 

“We look forward to welcoming back our students for the first semester. Strict safety protocols are maintained on all our campuses, including hygiene, social distancing, and the wearing of masks. It is also a privilege to welcome the new cohort of first-year students entering the university for the first time,” says Prof Petersen.

The university also offers online academic advising to help students plan their academic journey and to guide them through decision-making processes related to their study modules. Academic advising for senior and postgraduate students will take place from 1 to 26 February 2021, and for first-year students from 8 to 13 March 2021.

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.
