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.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
