According to Austin (1998:34), language is a tool used by human beings to communicate with each other. All languages have communicative value, meaning, and allow people to share thoughts, feelings, ideas, and exchange knowledge and opinions. No language is better or worse than the other, as all languages are equal in terms of their value and function. On the other hand, language dominance is a social process in which different languages are assigned different levels of importance, such that one language and its speakers carry higher social, economic, and political status than others. Subsequent to this practice, certain speakers struggle for recognition, while others enjoy a broader audience. Addressing language dominance, one needs to remember that language is not naturally hierarchical and that one must respect linguistic diversity and human rights at both individual and collective level. The concept of listening to one another then becomes a challenge, hence the theme: ‘Hearing you hearing me’ is so important in the 21st century.

How then can we as people resist or disrupt language dominance:
• Name and trace the history of language dominance
• The effects of inequity in daily language usage – not hearing each other
• The awareness and significance of multilingualism – learning other languages
• What universities can do and should do on a practical level to promote multilingualism

These are some of the aspects we look forward to discussing in the forthcoming webinar.

Prof Angelique van Niekerk is Associate Professor at the University of the Free State and the HOD in the Department of Afrikaans and Dutch, German and French. Her research focus is on applied linguistics within the field of semantics and pragmatics and on the linguistic nature of advertising communication. She has published many accredited publications within linguistics and communication sciences, in which she integrates her interest in both fields. She has a passion for teaching and (blended learning) course design within language acquisition. This has resulted in different registered SLPs within the department, focusing on Afrikaans as foreign language and Dutch as foreign language.

Prof Nhlanhla Maake is currently the Managing Director of the biggest merchandising company in South Africa, a position he has held since 2018. He has just completed a translation of SM Mofokeng’s Pelong ya Ka into English. The book is to be published in London, New York, and Calcutta in 2021 under the Elsewhere Texts series, edited by Gayatri Spivak and Hosam Aboul-Ela. 

He has held several academic positions nationally and globally and has served on several language task teams under the auspices of the Department of Arts and Culture; as a member of the Parish Pastoral Council at Our Lady of Mt Carmel in Thokoza; as a member and chairperson of the Catholic Bible College; as member and acting Chairperson of the English National Language Body of PANSALB; as Council member of the English Academy of Southern Africa; as Council member of the Afrikaanse Taalmuseum en -monument (2015 to 2017); and as Council member of the Wits Council on Education.

Prof Maake was an NRF (National Research Foundation) rated scholar (2006-11) and has held fellowships at Aarhus University (1983), on the Southern African Research Program (Yale University, 1989), Ernest Oppenheimer fellowship (UCT, 1992), and the Distinguished Scholars Programme (Wits, 1993). He was admitted to the Golden Key International Honour Society in 2005. He has presented papers and keynote addresses at more than 80 international and local conferences, is widely published, and has won several literary awards and recognitions.

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.
