Africa Month celebration on the UFS South Campus
Attending the Africa Month celebrations on the UFS South Campus were, from the left: Temba Hlasho, Executive Director: Student Affairs; Thandeka Mosholi, Head: Social Responsibility, Enterprise, and Community Engagement; Prof Colin Chasi; Ms Zola Thamae; Prof Francis Petersen; Simphiwe Dube, South Campus SRC President; Dr Cornelius Hagenmeier, Director: Office for International Affairs; Poloko Masuelele; Nombulelo Shange, Lecturer in Sociology; and Bulelwa Moikwatlhai (seated), Office for International Affairs.

Amid great fanfare, colour, and song, the South Campus of the University of the Free State (UFS) kicked off Africa Month in celebration of education on the African continent.

Delivering welcoming remarks on behalf of Dr Marinkie Madiope – the South Campus Principal – was Poloko Masuelele, Assistant Director heading the Curriculum Design and Development Unit on the South Campus. “The African continent is suffering a great deal of challenges, including the scourges of malnutrition and strained delivery of basic education. How revolutionary would it be if we could simultaneously eradicate these vices by formulating policies, mechanisms, and vehicles that would enable us to feed, heal, and teach our people? It is incumbent on us as thought leaders to take the lead in this significant enterprise.”

Bringing a government prospect, was Ms Zola Thamae, the Acting Director in the Free State Department of Sport, Arts, Culture and Recreation. She stated that there is much that could be done to address challenges in Africa if the university and government take hands. She also urged students to read and educate themselves in order to change their background. 

Searching for African solutions

Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, delivered the keynote address. Focusing on the theme of Africa Month, he said when it comes to educational development, there is no other continent that has faced the same trials and challenges as ours. “But in the harsh crucible of history, character, tenacity, and a sense of ubuntu were forged, translating into an exciting, fertile breeding ground for new knowledge creation, independent thought, and innovation,” he added. 

He quoted Paul Kagame, President of Rwanda, who said, “Africa’s story has been written by others; we need to own our problems and solutions and write our own story,” and added that over the past few decades, on many fronts and in many spheres – also in education – this is exactly what has been happening.

“We are actively searching for African solutions to African problems. The value we can offer is substantial,” he said.

Prof Petersen expressed confidence not only in Africa’s people, but also in what they are bringing to the table. “While Africa has established itself as an attractive investment destination, it is now more sought after for its people than for its physical assets. And its people have been driving exciting and encouraging developments in education.”

“In terms of Africa’s contribution to global knowledge, the world is slowly but surely acknowledging the abundant evidence of scientific innovation contributed by African scholars – not only at present, but since the earliest times.”

He also trusts that Africans have advanced considerably in decolonialising curricula. “Across our continent, African history, achievements, and discoveries have been absorbed into school curriculums, replacing a Eurocentric focus in education, and fulfilling the vision of Africans owning their own story. Most higher education institutions – the UFS included – have over the past decade or two also been engaged in a comprehensive, systematic process of decolonising our curricula – incorporating the knowledge created on our own continent in various study fields.”

Despite these encouraging milestones that education has reached in Africa, Prof Petersen is of the opinion that much remains to be done. “As custodians of higher education in Africa, and as part of the larger education sector, we have our work cut out for us,” he stated.

He believes that the unique point in time in which Africa finds itself presents an opportunity to completely reimagine the entire education landscape.

Collectively we will succeed

Also contributing some valuable input to the celebratory event, was Prof Lynette Jacobs, Associate Professor in the Department of Open and Distance Learning. She stated that one of the problems of colonial education is that it does not cultivate African self-esteem. Quoting President Julius Nyerere, she shared that “Education should not alienate students from their traditions but should rather make them appreciate themselves as Africans.” 

According to her, Africans have lost the confidence to celebrate themselves in their African cultures and traditions within the formal education environment.

“Collectiveness, togetherness, dialogue, and being authentically human are what Africa brings to the world. The world has so much to learn from Africa,” she said and asked the audience, “Do you embrace who you are and are you proud to share it with the rest of the world?”

Representing the Unit for Institutional Change and Social Justice was Prof Colin Chasi. He emphasised the importance of working together to bring about positive change in Africa. “We enhance our capacity if we are working together. Collectively we will succeed; separately we will suffer a terrible fate,” he stated.

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.
