During the Faculty of Education ceremony, Louzanne Coetzee, a blind UFS alumna and speaker, shared her remarkable journey. From her days as a high school learner to becoming a student, she highlighted her challenges and how she overcame them.

The April graduations at the University of the Free State (UFS) were a remarkable celebration of diversity and inclusivity, with 44 graduates with learning difficulties, visual, mobility, or hearing impairments honoured for their achievements.

Despite facing unique challenges throughout their academic journeys, these resilient students triumphed over adversity to earn their degrees, inspiring their peers and educators alike – all with the assistance of the Centre for Universal Access and Disability Support (CUADS) within the Division of Student Affairs.

Words of advice from the recent graduates

Nkosingiphile Nyanale, who is blind, recently graduated with a Bachelor of Laws (LLB) degree. He emphasised the importance of mutual understanding between students and educators as a way of helping students with disabilities to overcome the extra hurdles they face. “One of the most challenging parts of my journey was reaching a common understanding with some facilitators on how I could be reasonably accommodated in class,” Nyanale said. “Some lecturers would deny themselves the opportunity to understand the challenges of students with visual impairments and viewed my requests as a way of seeking an easy pass. So, peers and lecturers understanding various impairments helped shape my journey.

Sthembiso Dlamini, a BSc Mathematics and Mathematical Statistics graduate who lives with dysgraphia, a condition that creates challenges related to handwriting, spelling, and organising thoughts on paper, said, “In my third year, I struggled to focus during high-stress exams. I willingly sacrificed much of my leisure time to tackle this obstacle head-on. I committed myself to honing my learning methods and enhancing my time-management abilities.” 

Relebohile Moloi, a nursing graduate, thanked CUADS for its help, and said greater awareness of the centre and its services could help more students. “They should assess students regularly for impairments, because sometimes people don’t know they have an impairment. CUADS should visit each faculty to give information on who they are and what they offer.”

The speaker

Louzanne Coetzee, a blind UFS alumna, shared her story during the last graduation session of the season on 20 April. “After matriculating at the Pioneer School in Worcester [Western Cape], where it was a protected environment, I did not know what to expect from the UFS. However, the UFS gave me a conducive environment by allowing my guide dog, Isabel, into the residences. I was the first person to be allowed such.” [Listen to her full speech here.]

Inclusive environment

Martie Miranda, Deputy Director at CUADS, said she’s proud of the graduates, as they embody the UFS’s dedication to an inclusive environment that caters to all its students, in line with the university’s Vision 130, which aims to foster academic excellence in a diverse and equitable environment. “In celebrating our graduates, we honour not just their achievements but the enduring commitment of CUADS staff and the university to foster an inclusive environment where every student's journey is valued and supported."

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.
