Conference
At the meet-and-greet last night, were from left Prof Ruad Ganzevoort, Diversity Officer and Dean of Theology and Religion at VUA, Prof Francis Petersen and Dr Gene Block, Chancellor of UCLA.

The Unit for Institutional Change and Social Justice at the University of the Free State (UFS) is hosting a colloquium on Fragility and Resilience: Facets, Features and Transformation in Higher Education which started on 29 January, with the official progamme concluding on 30 January 2020.

The colloquium is a annual collaborative partnership between the UFS, University of California, Los Angeles (UCLA), and the Vrije Universiteit Amsterdam (VUA).

Apart from the overarching themes the colloquium also placed some focus on mental health, within this context as all three regions are witnessing a spike in mental health issues among students and staff as well as a deficit in terms of being able to sufficiently address the crisis.

“All three universities are committed to discussing global developments in diversity and transformation in higher education to discussing global developments in diversity and transformation as it may constitute itself in higher education circles around the globe,” says Dr Dionne van Reenen, convener of the 2020 colloquium and research fellow at the unit.  

The idea is to discuss what has and has not worked and, hopefully, access best practices in a variety of contexts. The partnership between the three universities spans over six years starting in 2014 when the UFS first hosted the research colloquium. It is the third time the UFS has hosted the colloquium.
 
Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, along with other members of the UFS Rectorate, attended a meet-and-greet on Monday 28 January 2020, and was joined by Dr Gene Block, Chancellor of UCLA, Vice Provosts Cindy Fan, Patricia Turner, Charles Alexander, Professors Abel Valenzuela, John Hamilton and Dr Shalom Staub, director of Community Learning, as well as Prof Ruard Ganzevoort, Chief Diversity Officer and Dean of Theology and Religion at VUA

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.
