University leaders from Africa and beyond will take part in a Regional Universities Forum for Capacity Building in Agriculture (RUFORUM) webinar on Wednesday, 10 June, to look at universities’ responses to the COVID-19 pandemic. Prof Francis Petersen, Rector and Vice-Chancellor of the University of the Free State, will be one of four panellists who will be the main speakers of the day. He is the only panellist from South Africa. 

Prof Petersen will participate alongside university leaders such as Prof Arthur Mol, Rector Magnificus of Wageningen University and Research in the Netherlands, Mr Hicham el Habti, Secretary General at the Mohammed VI Polytechnique University (UM6P) in Morocco, as well as Prof Barnabas Nawangwe, Vice-Chancellor of the Makerere University in Uganda. 

Getting together with other university leaders from the continent and abroad, speakers will share insights from their respective countries in dealing with the pandemic. The webinar takes place on 10 June 2020 at 13:00 South African time (14:00 East African Standard Time)

RUFORUM is a consortium of 46 universities in Eastern, Central, Western, and Southern Africa mandated to oversee graduate training and networks of specialisation in the countries and universities where it works. 

What is the webinar about?
The RUFORUM webinar titled ‘Learning from a crisis: University leaders’ response to the COVID-19 Pandemic', aims to tackle issues such as the immediate needs of universities, including staff realignment, dealing with the digital divide in the student community, institutional finance for operations and innovations in a changing landscape, and international students in a crisis moment. 

This webinar provides a great opportunity to galvanise collective responses from university leaders on this pandemic. It brings together universities from within and outside Africa on lessons learnt in confronting the immediate challenges and how they are resetting for a long-term perspective in the ‘new normal’. Interactions during this webinar will hopefully lead to a consensus on strengthening collective response and how universities can leverage one another in terms of the best practices and resources.  

The impact of the Coronavirus on higher learning institutions 
Given the devastation caused by COVID-19 across the world since its outbreak in China in December 2019, the impact has been felt in all spheres of the economy and global operations. Universities have also seen significant interruptions, including the UFS. Recently, RUFORUM conducted a study on the readiness of African universities to respond to COVID-19 and other natural disasters. This was meant to determine the level of preparedness of our institutions in facing this global pandemic and how to move forward as a continent while preserving the quality of the higher education that we deliver.  

The webinar will build on those findings and project a way forward in this unchartered territory of diminished financial resources, personal and academic challenges for staff, students, and institutional systems, the urgent need for improved infrastructure to respond to the demand for blended learning as well as remote learning approaches, and the limited mobility of students, academic and other staff, among others. Addressing these issues resulted in collaborations such as those initiated by RUFORUM.

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

17 September 2013

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.
