Prof Geofrey Mukwada says funding from the US Embassy and Consulates in South Africa will reinforce the ARU mandate.

The University of the Free State (UFS) will further strengthen its ties with the Appalachian State University in the next two academic years through a mountain-to-mountain research project funded by the US Embassy and Consulates in South Africa.

The R8 million project between the UFS and the US institution will cover the two master’s degree programmes in underdeveloped niche areas, meteorological weather stations, leadership capacity building for black women in academia, and doctoral research projects. Qwaqwa Campus departments that will be involved are Physics, Geography, Community Development, and the ARU.

Talking about this collaboration, the project leader, Prof Geofrey Mukwada, said it would bring together researchers from both the UFS and Appalachian State University and enable them to work together to develop what is currently an underdeveloped research niche, i.e. mountain studies. 

“This project will reinforce the mandate of the Afromontane Research Unit (ARU). It will provide the basis for a long-term development agenda through training and infrastructure development. For instance, the project will fund the implementation of two master’s degree programmes – the MSc in Mountain Environments and the MA in Community Development – which are long-term projects,” he said. 

“It will also support innovation in climate change research. Through this project, it will be possible to receive climate data from weather stations that are situated in distant, isolated, and generally inaccessible locations without travelling to those locations. We will be able to understand how the climate of the region is changing and assist in developing adaptation measures and decisions that are applicable to agriculture, water, tourism, environment, and other sectors. This will enhance the capacity of the ARU to contribute to the development of research in mountain environments,” he added. 

There will be a virtual launch of the project on Tuesday 10 November 2020 at 15:00 (CAT).

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.
