Prof Rodwell Makombe, Associate Professor in the Department of English on the Qwaqwa Campus.

Prof Rodwell Makombe, Associate Professor in the Department of English on the university’s Qwaqwa Campus, will be joining a prestigious group of more than 100 academic staff from African universities for this year’s University of Michigan African Presidential Scholars (UMAPS) programme.

Each year, the programme hosts more than 180 academics from different universities in Africa for a five-month fellowship, providing academics with access to the university’s research libraries and facilities, on-campus housing, health insurance, and a stipend to cover living expenses.

Fellowship an opportunity for collaboration and career growth 
 
The fellowship comes at just the right time for Prof Makombe, who said he is looking forward to mentorship for his growth and career development in a new environment and atmosphere. “I am very excited about this opportunity, which I think has come at the right time. It will expose me to a broad network of scholars, which I need for collaboration purposes, and it will also give me an opportunity to share my research and learn from the experiences of other scholars from different parts of the world. Given that I will be working closely with a faculty member of the university for the duration of the fellowship, the programme will also provide me with the mentorship that I need for my growth and career development.”
 
Apart from the exposure to broad academic and research scholars, he said he was looking forward to having the time and resources to finish writing his second book.

“I have just published my first book in October 2021, and I have already started doing research for my second book. The fellowship will give me time and space to focus on writing the book without the usual interruptions associated with my teaching responsibilities. The book focuses on cultures of resistance in post-Mugabe Zimbabwe. It is a sequel to my recent book,Cultural texts of resistance in Zimbabwe: Music, Memes, Media, which explores discursive resistance in Zimbabwe in the context of crisis.”

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.
