Dougie Heymans
Dougie Heymans was the Head of Rugby at the University of the Free State until his passing.

A Shimla great, a passionate rugby and family man, and a dream colleague are just some of the descriptions of how Dougie Heymans will be remembered.

Heymans, Assistant Director: KovsieSport and Head of Rugby, passed away on Monday due to the COVID-19 disease. He was 58.

He will leave a massive legacy in his capacity as rugby administrator, said DB Prinsloo, Director of KovsieSport. “Dougie was so precise in his work. He had a huge work ethic. Everything he did was textbook stuff. He is going to be missed immensely.”

According to Prinsloo, messages of condolence have been pouring in from far and wide. One of many was from former Protea cricket great, Allan Donald, nowadays the head coach of the Knights cricket team.
“It is indeed a shock to the entire sporting world. I knew Dougie very well, his involvement with varsity rugby, but also rugby in the Free State, made a huge impact on sports. This is a huge loss not only for the Cheetahs, but also Bloemfontein and the entire region. We sadly lost a legend,” he said.

Heymans played for the Shimlas between 1989 and 1994 and went on to represent the Free State in 154 matches until 2001.In 2009, he started working for the University of the Free State. He was the man in charge of Varsity Cup matches at Shimla Park.
“They say no one is irreplaceable, but it is going to be tough to follow in his massive footsteps. It is very hard not having him around anymore. He was a fantastic colleague,” Prinsloo said.

Former Shimla and Springbok, Toks van der Linde, who played with and against Heymans, said he had lost a great friend. “He was more than a friend, like a brother to us younger guys. RIP big brother, we are going to miss you.”

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.
