student dialogue
Dialogues presented by the Office for International Affairs provide a safe space for people to voice their opinions, to learn, and to engage. Here are, from the left: Montsi Ramonaheng, third-year BSc student majoring in Biochemistry and Genetics; Lebohang Lesenyeno, third-year LLB student; Motsaathebe Serekoane, Lecturer in Anthropology; and Bulelwa Moikwatlhai from the Office for International Affairs.

Will the creation of one African country solve the problem of xenophobia? 

This was the question raised at a recent dialogue session on the University of the Free State Bloemfontein Campus.

Most attendees believed the concept of ‘one Africa’ implied that only one language and one dominant culture would be needed – resulting in the spirit of multiculturalism ceasing to exist. When one speaks of a united Africa, it means that the continent recognises the diversity of its cultures and embraces these diversities. It was concluded that one Africa was not a solution to ending xenophobia.

Awareness of xenophobia from a human rights perspective

The Office for International Affairs hosted the two-dialogue series aimed at addressing an array of social issues such as xenophobia, cultural appropriation, and xenocentrism. They wanted to demonstrate the influence these issues have – not only on the mindsets of individuals, but also on how it can contribute towards the development of an unjust society devoid of embracing difference.

The first session was titled: Burn the Phobia, with the theme: ‘We are all foreigners somewhere’. The aim of this dialogue was to create awareness of xenophobia from a human rights perspective. 

Recently, a second dialogue session was presented, with the theme ‘Appropriation vs Xenocentrism’. According to Bulelwa Moikwatlhai, Officer in the Office for International Affairs, the purpose of this session was to encourage people to appreciate their own cultures and to respect other peoples’ cultures.

“We wanted to critically discuss cultural appropriation versus xenocentrism in an attempt to find a human response that is inclusive in nature,” says Moikwatlhai.

Direct outflow of UFS Integrated Transformation Plan

The lecture was presented by Motsaathebe Serekoane, Lecturer in the Department of Anthropology at the UFS, who urged attendees to always keep it authentic. He also stated that, as boundaries between the North and the South collapsed and knowledge flowed in and out, knowledge from the South was not taken seriously. 

“We lost ourselves within what happened in the North. We want to be appropriate and we want what they have, because it is more beautiful than what we have. We need to find something in Africa that will define us as African,” he says. 

These dialogues are a build-up to the International Cultural Diversity Festival that will take place at the Thakaneng Bridge on 13 September 2019 from 12:00 to 14:00.

The dialogue is a direct outflow of the university’s Integrated Transformation Plan. “We strive to cultivate a culture where everyone feels welcome and comfortable. We want to create common ground for international and South African students to get together and to collaboratively discuss issues from both parties in order to find innovative solutions to student challenges,” indicates Moikwatlhai.

Much of what is learnt in these sessions is used for reflection in order to improve the overall student experience. According to Miokwatlhai, it is essential to ensure that all processes related to students are structured to be socially just and inclusive. 

“As an institution of higher learning, we need to continuously create such platforms so that we have rich engagements about pertinent issues that affect the UFS community, and find human solutions to overcome barriers,” she concludes.

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.
