University of the Free State (UFS) Alumni may be based all around the world, but the United Kingdom (UK) Alumni Chapter aims to reconnect with all those members.

The UK Chapter is a hub of a developing UFS international programme. “We want to provide an opportunity for alumni to share their university experiences with wider audiences,” explains Carmenita Redcliffe Paul, Assistant Director: Alumni Relations and Business Development at the UFS.

Platform to celebrate successes

“The programme aims to provide a platform to alumni to celebrate their successes and provide a window to the landscape of the life and times of the university and the people who shaped it.”

“We also want to celebrate the diversity of our former students and the many touchpoints which unite them.”

Two key projects, Global Citizen and Voices from the Free State, came to life as a result of the collective collaboration of this chapter. The Global Citizen invites people in a series of “courageous conversations” to rethink their relationship with the world. Voices from the Free State is a series of personal podcast narratives by outstanding alumni wherein they reflect their experiences at the UFS. They tell their stories and explain how their university years shaped their future and paved the way to their respective successes.

Relevant association with the UFS

“Furthermore, they motivate why their ongoing association with the UFS is still relevant and important,” says Redcliffe Paul.

The UK Alumni Chapter is led by alumni Francois van Schalkwyk and Keenan Carelse and supported by Adrienne Hall.

Redcliffe Paul says Carelse and Van Schalkwyk have been instrumental in the Voices from the Free State initiative as they are strategically and operationally invested. They create and co-host the podcast series.

Van Schalkwyk is an entrepreneur and innovator consulting with clients globally. Carelse is employed in the healthcare sector in the UK.

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.
