If you attended the two-day workshop hosted by our Department of Political Sciences and Governance, you would understand how the South African higher education and political landscapes will be defined and transformed during this important election year.

Hosted for the ninth year in collaboration with the Osaka School for International Public Policy and the Southern African Center for Collaboration on Peace and Security Studies, the workshop brought together the cream of international and national political and security studies experts in the country. Prof Virgil Hawkins from the Osaka School for International Public Policy was the honorary guest.

Theme resonates with current issues
 
“The theme of the workshop ‘South Africa and Africa: Between Promise and Peril’ is fascinating. Between those is a sense of the in-betweens, the intermediate. This is basically where we found ourselves,” said Prof Heidi Hudson during her opening remarks at the worshop.  

Prof Francis Petersen, UFS Rector and Vice-Chancellor, spoke about the future of South African universities. “#RhodesMustFall and the subsequent #FeesMustFall movements were a crossroads which determined the path of higher education,” Prof Petersen said. This intervention reshaped higher education. Coupled with that was the announcement of subsidised free higher education for the poor and working class.

Service delivery and national elections

Dr Sethulego Matebesi from the UFS reflected on service-delivery protests. “Looking at key trends of service delivery, I have identified eight key trends since the eruption of service delivery protests in 2004.” Some of these trends include; the frequency of protests, geographic distribution, violent nature, the government’s response to these protests and new emerging trends of schools being held as a bargaining power.

“In each election year there seems to be a high prevalence of service-delivery protests,” he said.

Roland Henwood from the University of Pretoria spoke about the importance of the upcoming May elections and whether they will change anything for the country. “We have to be realistic about the expectations that surround the elections,” he said. There will not be any significant changes. “It is projected that the ANC will again win with a 50% majority. The results of the local elections of 2016 should not be referenced as different issues were at play then,” he said.

The workshop took place on 11 and 12 February 2019 on the UFS Bloemfontein Campus.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

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.
