The iKudu project, which is an European Union-funded Capacity Building in Higher Education (CBHE) project, has recently launched its blog, which aims to amplify the diverse voices of all iKudu stakeholders. In this space, members of the iKudu team will regularly share their views on the project and related international education topics.
The iKudu project focuses on developing a contextualised South African concept of Internationalisation of the Curriculum (IoC), which integrates Cooperative Online International Learning (COIL) virtual exchanges. The project was launched by the UFS in 2019, together with nine European and South African partner universities. It is funded by the European Union’s Erasmus+ programme with EUR999 881 (approximately R20 million) and is implemented over a three-year period.
The iKudu project is based on the fundamental belief that it is necessary to rethink internationalisation in an uncertain world. First, it is crucial to recognise and transform the power dynamics underlying international academic collaboration. Second, it is essential to develop pedagogies that allow every student to participate in international education, integrating technology where appropriate.
However, while all stakeholders agree on the fundamental tenets of the project and its principal goals, all iKudu stakeholders contribute different perspectives. In the blog, the iKudu stakeholders will provide a space for intellectual discourse on the project and related international education topics, which will allow constructive and critical engagement.

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.
