2024 Senate Conference
Keynote speakers during the UFS 2024 Senate Conference included, from the left: Prof Kristina Josefsson from University West, Sweden; Prof ‘Funmi Olonisakin from King’s College London, England; Prof Francis Petersen, Vice-Chancellor and Principal of the UFS and Chairperson of the Senate; and Prof Relebohile Moletsane from the University of KwaZulu-Natal.

The University of the Free State (UFS) presented its inaugural Senate Conference on the Bloemfontein Campus from 11 to 12 March 2024.

The conference, themed ‘Making Change through Engaged Scholarship’, initiated an important suite of conversations aligned with the UFS’ aspirations with Vision 130. The programme – which covered a wide range of topics by national and international speakers – included case studies of engaged scholarship from faculties, as well as breakaway sessions during which pertinent questions around engaged scholarship were discussed. A key element of the programme was the screening of a documentary film titled One Day, which accentuated the significance of engaged scholarship.

The organisation of the conference – both conceptually and logistically – was led by Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation at the UFS, supported by an organising committee consisting of various role players across the university.

Importance of engaged scholarship for universities

In his opening remarks, Prof Francis Petersen, Vice-Chancellor and Principal of the UFS, said that in the higher education sector, universities in South Africa, continentally, and globally are grappling with the key challenges of our time, including social justice, environmental degradation, and economic growth and job creation.

“We encounter these challenges in a global context that is increasingly volatile, and in which universities must constantly innovate and adapt in order to remain vibrant, relevant, and impactful. This is a time for higher education that is demanding, fraught, and disruptive. The challenges are many and complicated,” said Prof Petersen.

“Engaged scholarship is crucial for universities, particularly those in the Global South, as it fosters community collaboration, addresses local challenges, and promotes sustainable development,” he said.

Conference proceedings showcased of UFS’ involvement in engaged scholarship

On day 1, presentations included a discussion on ‘Engaged Scholarship in a Time of Geopolitical Contestation: An African Perspective’ by Prof ‘Funmi Olonisakin from King’s College London, England; and ‘Knowledge Products and Scholarship Engagement: The Way Forward for Universities’ by Prof Eugene Cloete from Stellenbosch University. The programme included a screening of a documentary film about engaged scholarship, titled One Day. Produced by Charlene Stanley from Storytown Productions, the film focused on the collapse of the tailings dam wall at the Jagersfontein Mine in September 2022 and the severe sludge damage to houses, property, and the environment. In particular, the film highlighted how the university’s interventions made a difference to the community. The day was concluded with presentations of engaged scholarship case studies from faculties, as well as group discussions.

Day 2 started off with a presentation by Prof Kristina Josefsson from University West, Sweden, on ‘Work-Integrated Learning and Engaged Scholarship – Meetings of Knowledge to Create Positive Change’, followed by a presentation on ‘Rurality, Community and Engaged Scholarship’ by Prof Relebohile Moletsane from the University of KwaZulu-Natal. As was done the previous day, presentations of engaged scholarship case studies from faculties and group discussions rounded off the day.

Some of the issues that have been identified and need to be taken further in order to embed engaged scholarship within the UFS, include the need to create a common understanding of engaged scholarship through careful interrogation of the terminology; the co-creation of knowledge, inter- and transdisciplinary approaches to solving problems; the impact of engaged scholarship on teaching, learning, and research interventions; and the sustainability of projects when the engaged scholars leave a community, and how to measure success or otherwise.

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.
