The Johannesburg High Court Judiciary Chambers donated a new wheelchair to David Phakoa Mashape from the UFS.

The Johannesburg High Court Judiciary Chambers contacted the University of the Free State (UFS) Center for Universal Access and Disability Support (CUADS), expressing their desire to donate some wheelchairs to Kovsies in need. 

David Mashape, UFS Corporate and Marketing Communication student, heard the news and did not hesitate to show his keenness to possibly receive the wheelchair. He was soon after contacted by CUADS; Free State High Court Judge, Pitso Molitsoane, personally delivered the wheelchair to David at the UFS CUADS offices in April 2019.

David explained that he had been saving up for a new wheelchair for a while, as his own was quickly wearing out.  He further mentioned that he has aspirations to play wheelchair track sports, including wheelchair racing and wheelchair rugby, and that he can now focus his savings on purchasing himself a brand-new racing wheelchair, courtesy of the generous donation from the Johannesburg High Court Judiciary Chambers. 

As stipulated in their operative mandate, CUADS strives to facilitate, create opportunities for, and enhance students’ critical thought and ways of being that are consistent with human rights and the principles of social justice. This mandate is evident in the small every-day victories, such as David’s, facilitated by the department to ensure humanising daily lived experiences essential to cultivate student academic success, social engagement, and cohesive institutional culture.

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.
