The University of the Free State (UFS) has selected MPhil (African Studies) student and self-proclaimed ‘radical feminist’, Shannon Arnold, and former Golden Key UFS Qwaqwa Campus Chapter President and Political Studies and Governance honours student, Samkezi Mbalane, to represent the institution this year on the Abe Bailey Travel Bursary tour

The Abe Bailey Travel Bursary is a leadership-development programme that honours and targets university students or junior lecturers with a strong academic background, and who have shown exceptional qualities of leadership and service during their university careers as well as in a wider social context. Recipients of the bursary are expected to function as an integral part of a select and highly skilled group of individuals who will be embarking on a five-stage tour in December, starting in Cape Town (South Africa) and finishing in London (United Kingdom).

“Success comes from a feeling of satisfaction in what I have done for myself” – Shannon Arnold

Shannon Arnold, who is originally from Grahamstown, Eastern Cape, completed her undergraduate and honours studies in Political and International Studies and English Literature at Rhodes University. She moved to the UFS and is currently completing her transdisciplinary MPhil in African Studies, focused on Peace and Conflict in Post-conflict African Societies from a gendered perspective. 

“Moving to the Free State was an interesting cultural transition,” Arnold remarked. 
She further expressed how “pleasantly enlightened” she was by the UFS’s active and direct approach to transformation, and how it allowed her to spearhead and coordinate crucial student-movement initiatives such as the total shutdown protest which saw women and students march from the UFS Bloemfontein Campus to the Supreme Court of Appeal in 2018. Arnold believes that her passion, work, and experiences with community and service-based organisations against South Africa’s plight of gender-based violence has branded her a leader and qualified her for becoming an ‘Abe’.

Arnold grew up in a community-minded family and has thus been aligned with politics from a very young age. She is inspired by the thought of manifesting a reality where women in South Africa are able to pursue their own choices. She looks forward to exposing herself to foreign cultures on the tour to the UK, engaging with people who have like-minded convictions. 

“The desire and compassion to motivate and uplift others is what inspires me.”  – Samkezi Mbalane

Eastern Cape, Mount Fletcher-born Samkezi Mbalane, who graduated from the UFS with his undergraduate degree in Political Studies and Governance (Cum Laude), labels his life journey as ‘very difficult, yet fascinating’. 

Having been raised by a struggling single mother, he reflects on being dependant on other people in his immediate community for basic needs. He lived in a foster home for three years (Grade 10 to 12) as a means of survival. Mbalane explained that such experiences motivated him to pursue a career in politics, as he dreams of playing a pivotal role in the creation and implementation of South African governmental policies that will one day effectively benefit the poor.

Mbalane believes his claim to leadership came through ‘hard work and persistence’. He has served in various leadership positions, including President of the Golden Key Society UFS Qwaqwa Campus Chapter, Prime at Steve Biko Residence, active member of the Institute for Reconciliation and Social Justice, Enactus, and the Secretary General of the Student Parliament. Mbalane deemed being selected an ‘Abe’ as an “iconic opportunity for all aspirant leaders in South Africa.” 

He looks forward to working with people from different cultural backgrounds and career fields, but mostly, to seeing the world outside South Africa from a unique perspective.

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.
