Takudzwa Nyamunda.

Takudzwa Nyamunda is the proud new representative of the University of the Free State (UFS) for the 2020 Commonwealth Future Student Leadership programme. Nominated at a recent workshop themed ‘Reimagining Peace’, organised by the Association of Commonwealth Universities in collaboration with the British Council and the Durban University of Technology, Takudzwa demonstrated exceptional leadership, coupled with his experience of issues related to the UFS student committee, which provided the perfect foundation for his selection. 

“From a personal point of view, this was one of the most enriching experiences I have ever had, both in terms of the relationships established and the world knowledge gained. I am personally grateful for the opportunity to attend and would support any further initiative of this nature. I think the essence of this workshop was to encourage the young leaders present – all of whom were active citizens in their communities in one way or another – to continue fighting the good fight. The core message from the panellists was that it is all worth it in the end, and that even in the face of adversity and discouragement, we should keep fighting for the work we believe in,” says Takudzwa. 

Participants from 13 nations, including activists and thought leaders on non-violence affiliated with the International Centre of Nonviolence, the Gandhi Development Trust, and the Commonwealth Countering Violent Extremism Unit, contributed to the workshop. Over the course of three days, participants were divided into five groups and worked together on projects linked to three main themes – gender-based violence, global warming, and inequality.

The selection committee was convened by the Vice-Rector: Research and Internationalisation, Prof Corli Witthuhn, and facilitated by the Office for International Affairs. Currently in the final year of his Master of Industrial Psychology degree, Takudzwa’s wealth or experience includes being the founder and first president of the International Students Association (2016), and holder of the International Student portfolio as Student Representative Council (SRC) member (2017), coupled with being co-founder and first vice-chairperson of the South African Board for People Practices (SABPP): UFS Chapter and Vice-president of the SABPP National Youth Council (2019).

“I will continue to do what I have been doing for the past five years at the UFS, which is to make a difference in my sphere of influence”, says Takudzwa.

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.
