The University of the Free State Library and Information Services (UFSLIS) hosted stakeholders from SABC Lesedi FM, the Free State Department of Sport, Arts, and Culture, the Pan South African Language Board (PanSALB), and delegates from the National Library for the launch of the first-ever African Languages University Press in South Africa and Africa.  The launch, which took place on 24 May, deliberately coincided with the Africa Month commemorations – as the UFS’ answer to the United Nations General Assembly (Resolution A/RES/74/135) proclamation of the period between 2022 and 2032 as the International Decade of Indigenous Languages.  

This proclamation aims to draw global attention to the critical situation of many indigenous languages, and to mobilise stakeholders and resources for their preservation, revitalisation, and promotion. The University of the Free State Department of African Languages aims to be a publisher of high-quality original African language monographs and research in order to promote access, preservation, and use of marginalised African languages.  

In his opening remarks, Marcus Maphile, Assistant Director: Library Services, said, “As a broad academic publisher, the African Languages Press will be working across a number of markets, all presenting challenges and opportunities for established and engaged university presses. One of the opportunities will be to challenge the mainstream book publishers to re-enter the indigenous language publishing market.” He further said that this was done to make writing and reading in African indigenous languages fashionable, for other nations to envy our rich multilingual cultural heritage. 

The guest speaker for the launch was the UFS honorary Doctor of Letters (DLitt) recipient, Dr Jerry Mofokeng wa Makhetha, who applauded the University of the Free State for taking such a bold step towards enriching and developing African indigenous languages. 

The launch offered the UFS the opportunity to reach out and engage the international community on potential partnerships and collaborations towards developing African languages. The Library Director, Ms Jeanette Molopyane, provided insight into the challenges faced by libraries due to the shortage of books in African languages, while positioning the University of the Free State Library as a trendsetter and a leader in the development of best practices in the field of libraries.

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.
