Kovsie Eco vehicle parade
A highlight for first-year and senior students is the ACT eco-vehicle building and parade through the streets of Bloemfontein.

Sunny skies, cheerful faces, and an overall great atmosphere surfed the University of the Free State (UFS) Bloemfontein Campus on Saturday, 1 February 2020 for the final series of events in the Kovsie ACT 2020 line-up.

The eco-vehicle parade kick-started the activities for the day and saw various student teams displaying their personalised pit-stop ‘sculptures’ along the streets of Bloemfontein.  UFS residence teams Sonverlief (Houses Sonnedou, Veritas, Madelief); Soetmarmentum (Houses Soetdoring, Marjolein, Armentum); and Beykasium (Houses Beyers Naudé, Akasia, Imperium) came in first, second, and third respectively, obtaining the highest scores out of nine teams for their pit-stop sculpture constructions. 
 
Following the parade, there were a number of fun but competitive eco-vehicle races between the teams. This included the Drag Race, Obstacle Course Race, Formula E Race, Endurance Race, and the Slalom Course Race that took place on the Mokete Square. 

In the evening, students were serenaded by artists such as Early B and Spoegwolf. They danced to performances from the latest Amapiano music sensation, Kabza de Small, and legendary deep-house music duo, Black Motion, at the Rag Farm. 

Assistant Director of UFS Student Life and Director of the Kovsie ACT office, Karen Scheepers, earlier urged students to get more involved in student-life programmes such as Kovsie ACT, in order to equip themselves with a variety of skills and a fulfilling university experience.

A number of senior and first-year students who were part of the action on the UFS Bloemfontein Campus this past Saturday, can attest to Scheepers’ advice.
“I’ve been looking forward to starting university for the longest time, and I am glad that I ended up at the UFS. I don’t feel alone, I feel like I can actually do this,” said first-year Psychology student, Thulisa Shezi.

“University isn’t as bad as everyone thinks it is, it’s just a matter of staying motivated, doing your work, and surrounding yourself with the right people in the process.” – Fourth-year Business Management student, Earl van der Westhuisen.

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

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.
