Reading Culture
The University of the Free State Faculty of Humanities and the Library Information Services proudly established a brand-new school library at Kagisano Combined School on 14 May 2024.

In a bid to cultivate a culture of reading within the community and bolster the University of the Free State's (UFS) Vision 130, the Faculty of The Humanities has embarked on a transformative journey of collaboration with the Library Information Services (LIS). This partnership symbolises a commitment to not only academic excellence, but also social responsibility, aiming to make a tangible difference in the lives of those within our community.

On 14 May, the Dean’s office – in synergy with LIS and the Department of Plant Sciences – undertook a meaningful venture at Kagisano Combined School in Ikgomotseng to establish a school library, making it an engaging and welcoming space for learners.

Led by Dr Dimitri Veldkornet and supported by four dedicated PhD candidates, the Department of Plant Sciences has made a remarkable impact by enhancing the library's surroundings with indigenous flowers. Beyond mere beautification, this initiative also served as an educational opportunity, as five learners from the school were trained to care for these plants, fostering a sense of ownership and environmental stewardship.

Colleagues from LIS meticulously and simultaneously organised the library space, ensuring that reading materials were properly catalogued and shelved for easy access. In addition, LIS generously donated furniture, including shelves, tables, and chairs, to create an inviting environment conducive to learning and exploration.

The collaborative effort extended beyond academic circles, as the community of Ikgomotseng and Letsatsi Trust demonstrated remarkable hospitality by combining resources to provide refreshments for UFS colleagues and community members involved in the initiative. This gesture exemplifies the power of collective action and highlights the interconnectedness between the university and its surrounding communities.

By revitalising the school library and fostering a culture of reading, this partnership exemplifies the core values of social responsibility and community engagement espoused by the UFS. Moreover, it underscores the university's commitment to Vision 130, which envisions a future where education transcends the confines of academia to positively impact society at large.

As we continue to forge ahead, let us remember that true progress is measured not only by academic achievements, but also by the meaningful contributions we make to the communities we serve. Together, through collaboration and compassion, we can create a brighter, more inclusive future for all.

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.
