The University of the Free State’s Department of Private Law in the Faculty of Law recently hosted an enlightening seminar titled 30 years of democracy in South Africa on 26 April 2024. Dr Marianne Sèverin, from the Institute for African Studies at Bordeaux University in France, graced the event with her expertise. Her doctoral research delved into the Political Networking of the African National Congress (ANC), providing a rich backdrop for her discussion on South African democracy with the faculty’s esteemed staff and eager students.

Navigating the adolescent years

In her engaging discourse, Dr Sèverin likened South African democracy to that of “a teenager”, acknowledging the strides made since the advent of democracy in 1994. However, she astutely pointed out that despite the country boasting a robust Constitution, the pervasive issues of corruption and poverty remain significant hurdles. Drawing from her deep knowledge of the ANC, she shed light on the party’s overwhelming dominance in politics, which, unfortunately, provides fertile ground for corrupt practices to flourish unchecked.

The perspective of the ‘born free’ generation

Of particular interest to Dr Sèverin were the perspectives of the young attendees, affectionately known as the ‘Born Free’ generation, who never experienced the apartheid era firsthand. Their casual acceptance of democracy struck a chord with her. Dr Marda Horn, Senior Lecturer in the Department of Private Law noted, “She found through her discussions that they seemed to take democracy for granted and did not appreciate how lucky they were to live in a democracy.”

Lessons from across the continent

Throughout her presentation, Dr Sèverin artfully weaved in anecdotes from other African nations, such as Zimbabwe, Congo-Brazzaville, and the Democratic Republic of the Congo, where democracy has faltered. Her passion for South Africa was palpable as she recounted the emotional moment she experienced during the Rugby World Cup in France in 2023 when the national anthem resonated. Expressing her admiration for the ethos of “ubuntu” demonstrated by the Springboks, she confessed that this philosophy has become her guiding principle in life, a testament to the profound impact of South African culture on her.

A call to cherish and safeguard

The seminar provided a platform for deep reflection on the progress and challenges of democracy in South Africa, urging participants to cherish and safeguard the hard-won freedoms of the nation. As South Africa approaches the elections scheduled for 29 May 2024, the seminar serves as a timely reminder of the importance of youth engagement in shaping the country’s democratic future.

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.
