Lerato Mbongo and Opheleleyo
Double belted! Opheleleyo Qwabe and Lerato Mbongo revel in the moment.

Their friendship began in high school, where they were constantly told by teachers that they would not make it to university, but these best friends never gave up. On Thursday 21 April 2022, they received their honours degrees in the Faculty of Natural and Agricultural Sciences together during the afternoon ceremony of the University of the Free State’s April Graduations.

Lerato Mbongo and Opheleleyo Qwabe, who have been friends since Grade 9, said being picked on in class for not being the brightest learners brought them together and motivated them to work harder.Mbongo obtained a Bachelor of Agriculture Honours majoring in Wildlife Management, and Qwabe received a Bachelor of Agriculture Honours majoring in Agricultural Economics.

“We’ve always dreamed big, but if you had told us back then that we would one day be two-time graduates, we wouldn’t have believed it. During one of our Maths lessons back in Grade 9, our teacher went around asking the ‘smarter’ kids what they wanted to study after matric, but when he got to us, he said there was no point in asking because we wouldn’t make it that far anyway,” Qwabe said.

The friends, who both started at the university’s South Campus, said they were grateful for the UFS Preparation Programme, as it boosted both their marks and their confidence. “The programme helped us to believe in ourselves again, and also played a big role in helping us discover what we wanted to study. The courses we enrolled in really unlocked an unstoppable passion in us and helped us realise that nothing is impossible. Today, here we are celebrating 10 years of friendship, and our honours degrees. We’ve conquered once again, and we're sharing our victories together,” Mbongo said.

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.
