The post-school life of Francois de Beer, one of the graduates in the Faculty of Natural and Agricultural Sciences who obtained his qualification in Chemistry and Biochemistry during the April graduation ceremonies, can be seen as one great act of ‘magic’. Other people may describe it as coincidence with a couple of miracles as the end result.

An opportunity 

After completing his schooling at Hoërskool Fichardtpark in 2008, Francois decided to study at the University of the Free State (UFS). “Kovsies gave me the opportunity when nobody else would,” said Francois. 

He did not have Maths subjects at school but wished to study in a Science field. “It is the closest one will ever come to doing magic,” he said.

The human element

Francois, who initially did not perform very well academically, did a bridging course in Mathematics and since then achieved distinctions in all his subjects. He related his story: “I did not have any Maths subjects at school, therefore it was very difficult for me to get to this path. The big difference was that Ms Elzmarie Oosthuizen from the UFS bridging programme saw something in me when nobody else did. She gave me the opportunity to do the Mathematics course, after which I was able to further continue on the Science path.”

“I would definitely recommend the UFS to other prospective students. I think Kovsies has a human element that really looks after students,” Francois said. 

Francois is currently pursuing his postgraduate studies in Chemistry. He wants to make a difference in the lives of other people, just as others made a difference in his life.

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.
