Communities are beginning to wonder if universities exist for themselves or for their communities. This is the view shared by Prof Pearl Sithole, Campus Vice-Principal: Academic and Research, during the opening of the two-day Travelling Seminar that was recently hosted on the Qwaqwa Campus. 

Research in communities

“This event is well-placed, considering what many communities are currently going through. We must ask ourselves what we are doing with and for our communities. We must be careful to not only reap data from them, but to be scientific in a way that accommodates our communities and allows the African and indigenous agenda into the world of science,” she added.

Providing background to the concept of homestays, the Director: Institute for Rural Development at the University of Venda, Prof Joseph Francis, acknowledged the role played by communities in research.

 “This seminar seeks to develop a testable framework for homestays; a concept enabling postgraduate students to be placed with rural families while conducting research in the area. It is also aimed at giving birth to a vibrant, community-based rural and regional development network connecting grassroots communities, business, government, and non-governmental stakeholders,” he said.

“We do not only train students for local deployment and within national borders. It is important to produce an ‘all-weather’ graduate who stands out wherever they are. Graduates must ask themselves, ‘what in me stands out among the rest?’ As a student and researcher, never see yourself as being confined to the space where you are,” he added.

Students as ambassadors

Cornelius Hagenmeier, Director: Office of International Affairs at the University of the Free State, said for internationalisation to work, it has to be inclusive and create student ambassadors. “As this seminar will show, our networks of stakeholder communities go beyond the national confines and borders. We must strive, through this project, to create ambassadors of the university, of communities, of the broader South Africa and Africa,” he said.

Participants in the seminar were academics and postgraduate students from both the Universities of the Free State and Venda. Also present were community and traditional leaders from Qwaqwa and the Vhembe District in Limpopo.

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.
