A story of hope, courage, resilience, and working your way to the top. Dilahlwane Mohono started working as a cleaner at the UFS in 1992. Today, she is a Senior Faculty Officer in the Faculty of Natural and Agricultural Sciences and holds two honours degrees.

Fuelled by her deep pain due to falling pregnant during her matric year, as well as the desire to one day hold a qualification, Dilahlwane Mohono – Senior Faculty Officer in the Faculty of Natural and Agricultural Sciences – says her story is her favourite, as it is a story of hope, courage, resilience, and working your way to the top.

Because of her pregnancy, Mohono did not complete Grade 12 in 1990. She got married immediately thereafter. In 1992, she began working as a cleaner for a company that was insourced to provide meals on the University of the Free State Qwaqwa Campus. She says this experience often left her with mixed feelings, as it hurt to see her peers studying further, but this is also what ultimately motivated her to complete her matric. “Graduation ceremonies were the most painful events for me. This eventually pushed me to turn to ABET to complete my matric in 1994. From there, I was determined to start my academic journey, so I registered with Stanford Business College for a Secretariat and Computer Skills Diploma. It was a six-month course, but I graduated in the end. That graduation inspired me. It motivated me to study further. Juggling work and studying became challenging, because I was a young mother and wife, but I had to attend classes after work.”

The joy of education

In 2000, she registered for a Higher Diploma with Unisa, and at the same time took up a new position in the library on campus. At the time, it was still called the University of the North Qwaqwa Campus. She recalls this as the beginning of her upward trajectory in life. “The joy of education and seeing how far I have come made me realise how much potential I have, so in 2003 I registered for a BA Sociology and English degree at the UFS, and thereafter went on to do my BA Honours in Sociology.”

She took up a new position as Assistant Officer in the Faculty of Education. Wishing to be relevant to her new faculty, Mohono completed a Postgraduate Certificate in Education (PGCE), and thereafter a second honours degree in Curriculum Studies. “I felt like I was flowing. My colleagues helped me out and I wanted to ensure that I was the best in everything, because I did not want to disappoint them. What always encouraged me, were my children. I separated from my husband in 2003, so I found myself raising my kids single-handedly, and I needed to show them that we could all make it, and life would still go on.”

In 2018, the Faculty of Natural and Agricultural Sciences advertised a senior position. Mohono says she took a chance and applied because she wanted more growth. “I am now a Senior Faculty Officer. I was privileged to be afforded an opportunity to work for the university, so I always thought – how can I work in an academic higher learning environment and not use the opportunity to study and pursue an education.”

Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?
It has to be my late mother. She was a very hardworking woman, but she passed on very early, in her early 40s. She worked in the same dining hall I started in, and a lot of the women I worked with then worked with her too. They took me under their wings and motivated me to continue chasing my dreams. Some were not even educated themselves, but they motivated me. I drew a lot of inspiration from them.

What advice would you give to the 15-year-old you?

She must take pride in being a woman, know who she is, and know that she must be brave and confident, and run with education as the key to her success. If it wasn’t for education, I shudder to think where I could’ve been. When I look back and see what I have achieved, being able to rise from all that while single-handedly raising my children, it makes me feel very strongly about myself. I am a very powerful woman.

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.
