Prof Bonang Mohale.


The executive management of the University of the Free State (UFS) and the university community extend heartfelt congratulations to Prof Bonang Mohale on his appointment as President of Business Unity South Africa (BUSA). 

“Prof Mohale’s extensive expertise and experience in leadership roles, contributions to the growth of many multinational companies, and involvement in education and the business sector, will undoubtedly strengthen the ties between various sectors and civil society, and further contribute to the stabilisation and growth of South Africa,” said Prof Francis Petersen, UFS Rector and Vice-Chancellor, in his congratulatory letter to Prof Mohale. 

BUSA’s role in influencing policy and legislative development for inclusive growth and employment, and in building an enabling environment for the creation of a vibrant, diverse, and globally competitive economy that harnesses the economic and human potential in South Africa, is well documented. This potential resides in our higher education institutions in the form of our students, future graduates, and graduates who are the building blocks for the development of South Africa. 

At a time when our country is facing a social and economic crisis, we are confident that BUSA will consider the perspectives across sectors with a view to creating partnerships, collaboration, and co-creation and further play an integral role in our higher education institutions for the benefit of our students. 

“Prof Mohale’s support to the UFS is appreciated, especially his role as Chancellor and his contribution towards our Thought-Leader and Global Citizen programmes, through which important national and global issues are addressed.
 
We wish Prof Mohale every success in his endeavours, particularly as President of BUSA,” said Prof Petersen.

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.
