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.

UFS researcher engineers metal surfaces
2015-03-03

It is well known that the surface of a component is much more vulnerable to damage than the interior, and that surface-originated degradation such as wear, corrosion, and fracture will eventually destroy the component.

“Engineering the surface, based on scientific knowledge, is essential to control these damaging processes. It also creates electronic and geometric structures on the surface which opens up a world of new devices, especially considering the properties on the nano-length scale,” said Prof Wiets Roos from the Department of Physics at the University of the Free State (UFS).

At elevated temperatures, atoms are more mobile and can migrate to grain boundaries and surfaces, which have a major influence on material properties. The redistribution of solute atoms between the surface and the bulk of the material is known as segregation. Knowing the behaviour of segregation at the surface/environment interface can be very useful in the development of new materials. As an example materials can be improved higher efficiency and lower fuel consumption, thus reducing environmental pollution.

The main aims of Prof Roos’s research are to understand surface segregation, use it as a tool, and contribute to the various surface engineering fields.

The surface characterisation laboratories at the UFS are well equipped to do high temperature segregation measurements, and have already proven a success, not only in the ability to prepare the specimens for characterisation, but also in developing models and procedures to quantify the segregation parameters.

The most recent results have demonstrated the importance of taking evaporation into account during quantification.” This has laid the foundation for future studies by installing the necessary hardware in a surface characterisation spectrometer, establishing experimental protocols, and improving an existing model (developed in this laboratory) for simulating segregation profiles,” said Prof Roos.

Segregation parameters allow the researcher to predict and utilise the surface concentration behaviour as a function of temperature and time. “This not only contributes to fields involving corrosion, oxidation, sintering, wear, chemical poisoning, powder metallurgy, and lubrication but adds to the development of self-healing devices,” said Prof Roos.
