Prof Loyisa Jita
Member of sixth Umalusi Council, Prof Loyiso Jita


Umalusi council members are appointed by the Minister of Education for their professional expertise in education and training. The council is formally mandated to research matters related to the sub-framework of qualifications responsible for the General and Further Education and Training qualifications. Prof Jita will be playing a governance role in Umalusi as an organisation.

Appointment a recognition of contribution to quality assurance systems

Sharing his sentiments on the appointment, Prof Jita said it was an affirmation of his dedication to delivering quality education in the country. “Being on the council is further recognition of one’s contribution to the quality assurance systems of the country and an elevation of the role in decision-making. The council, for instance, provides final approval of Grade 12 national results in public and private schools.”

He previously served on one of the Umalusi sub-committees responsible for assessment and standards, also known as the Grade 12 Standardisation Committee.

The sixth council will meet for the first time in September for induction and allocating specific roles to members.
 
Prof Jita joined the UFS in 2012. In 2014, the University of the Free State (UFS), in partnership with the South African National Roads Agency, launched the SANRAL Chair in Science, Mathematics, and Technology Education on the Bloemfontein Campus, and Prof Jita was appointed as the first SANRAL Chair. In 2017, he was appointed as Dean of Education.

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.
