UFS Africa celebration
I am not African because I was born in Africa, but because Africa was born in me,” Kwame Nkrumah, Ghana’s first president, and a founding father of the African Union.

Since the African Union’s establishment in 1963, the continent marks Africa Day on 25 May annually. To commemorate the achievements made by African leaders 56 years ago to decolonise the continent and pave the way for a united front on the global stage, the University of the Free State (UFS) hosts various events.

Ubuntu our beginning, ubuntu our ending 

The university celebrated Africa Day a day early this year. The Office for International Affairs coordinated the 2019 Africa Day Reflection and Celebration on 24 May 2019 at the Bloemfontein Campus. A dialogue session delved into the question of what ubuntu has evolved to mean in modern-day society and how best it can be embodied.

Moderator of the dialogue, Ace Moloi, reckoned that “we have a right not only to give ubuntu but to demand and invoke it from other people.” Staff, students and panellists engaged on the aphorism umuntu ngumuntu ngabantu and whether the philosophical principle is a pragmatic way of doing things or is only referred to when self-correcting.

Prof Colin Chasi, from the UFS Department of Communication Science, touched on how ubuntu is embedded in many Nguni languages. A case in point being the implied presence and connectivity typical found in indigenous language greetings. Other panellists including Prof Karin van Marle( Public Law lecturer at the UFS), Thapelo Mokoatsi,History lecturer at the UFS and Matau Setshase, UFS researcher, made contributions on decolonisation, individual identity, reconciliation, social issues, and traditional healers. The consensus reached was that a lot work still needs to be done in understanding and living the values represented by ubuntu.

Qwaqwa Campus Celebration

The Office for International Affairs (OIA) also hosted the first Annual Africa Day Student Dialogue on the Qwaqwa Campus under the theme: Health, Wellbeing, Access, Social inclusion, Equity and Equality on the African continent.

Africa Day Memorial Lecture

Presenting the 2019 Africa Day Memorial Lecture, Prof Francis Nyamnjoh, from University of Cape Town, delved into the topic of Ubuntuism and Africa: Actualised, Misappropriated, Endangered and Reappraised. “I seek to give currency to concepts such African communitarianism, ubuntu, Africanness, Afrocentricity, Afrocentrism, Africanity, Afrikology, humanness, wholeness and reciprocal altruism,” he said.

Hosted by the Centre for Gender and Africa Studies on 22 May 2019 the annual lecture is a calendar constant which reflects on the importance of celebrating the continent and its people.
 
Migration debate unpacked borders 

The UFS Debate Society reflected on borders and migration in Southern Africa on 21 May 2019. The debate unpacked the topic: The Southern African Development Community should develop a free internal migration policy. 

Lecturers also delivered presentations that dissected African societies, the nine frontier wars between the British and amaXhosa that formed South Africa’s borders, and the influence of labour and capital on migration. In closing, African international students shared their lived experiences, hardships and triumphs within the continent.

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.

 

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast 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.
