Dr Faith Mkwananzi’s road from secondary school to university has been paved with challenges. After repeating her matric five times in Zimbabwe, she became an international university student in South Africa in 2006. Some years later, on 3 April 2019, the University of the Free State’s (UFS) Bloemfontein Campus witnessed the launch of her excellent book titled: Higher Education, Youth and Migration in Contexts of Disadvantages: Understanding Aspirations and Capabilities, which was informed by these and many circumstances.

Aspirations formation

The book speaks to her own life. “Born and raised in Zimbabwe in KwaBulawayo, I had my own aspirations. I knew I did not want be a nurse   my mother’s earnest interest and desire for me,” said Dr Mkwananzi as she related the fluid dreams her seven-year-old self had that culminated into aspirations to enter academia.

Aspirations enabled Dr Mkwananzi’s capabilities to pursue a PhD in Development Studies at UFS, and then write her book. “Higher education aspirations are worth pursuing,” said the current postdoctoral researcher at the university’s South African Research Chair Initiative (SARChI) in Higher Education and Human Development Research Programme, as she reflected on her academic journey.

Voices of marginalised migrants
 

Dr Mkwananzi has focused her book on the lives, experiences and the formation of higher education aspirations among marginalised migrant youth in Johannesburg. She gives these young people a voice to narrate their own story, making this research an essential work for understanding the conditions necessary for youth to live valuable lives in both local and international contexts.

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.
