A Virtual celebration of Africa Month

On 25 May 2020, Africa will celebrate the 57th anniversary of the founding of the Organisation of African Unity. A central tenet of the organisation, which was the predecessor of the African Union, is African solidarity. Member states undertook to coordinate and intensify their cooperation and efforts to achieve a better life for the people of Africa. The University of the Free State (UFS) has a long tradition of commemorating Africa Day and the ideas underpinning it. Every year, diverse events aimed at advancing African unity and solidarity take place during Africa Month – traditionally, the highlight is the Africa Day Memorial Lecture hosted by the University's Centre for Gender and Africa Studies

This year, celebrating African unity through significant events involving the physical presence of a large number of people, will likely be impossible. COVID-19 is ravaging the world and Africa may become one of the world regions worst affected by the consequences of the virus. Social distancing may be difficult to achieve in a continent with densely populated urban centres that often feature large informal settlements. Besides, the economies of African nations are not as robust as those of other world regions. The challenge that Africa is facing, appears to be one that can only be mastered by its people acting in solidarity and unity. The continent has already developed an Africa Joint Continental Strategy for COVID-19 Outbreak to combat the virus, and an Africa Taskforce for Coronavirus has been established. The ideas of African togetherness and the underpinning philosophy of Ubuntu may be critical for strengthening African solidarity at a time when it may be more relevant than ever.

The commemoration of Africa Day takes a different theme each year. This year, the UFS 2020 Africa Month celebrations will take a virtual format, with the theme of ‘Africa together forever’ underpinned by the COVID-19 global pandemic. The theme is particularly significant considering the context of the African continent; and only through the demonstration of solidarity and unity can Africa overcome the challenges of the global pandemic.

The University will host a variety of cultural and intellectual contributions on the dedicated UFS virtual Africa Month website. On Africa Day (25 May 2020), a virtual Africa Day function, which will be posted on the website, will conclude the Africa Month commemorations.

The diverse contributions to the 2020 virtual Africa Month activities will highlight the University’s commitment towards creating a diverse, challenging intellectual environment. The UFS strives as a research-led university, to provide an environment in which new ideas are incubated and debated; contributing towards its transformation process and African unity.

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.
