A Master of Commerce degree with specialisation in Industrial Psychology will be conferred on Kgalalelo Motlhabane, a graduate and funding officer at the Postgraduate School at UFS on Friday 9 October 2020 in a virtual graduation.

One of the success stories of this year’s virtual graduation is Kgalalelo Motlhabane, a graduate and funding officer at the Postgraduate School, University of the Free State (UFS), who was presented with an award from the National Research Foundation as the best designated authority for 2019.

Motlhabane, who lost her mother when she was in high school, didn’t just have to overcome poverty on her way to her first qualification, but also the fear of ending up on the street. On Friday 9 October she received a Master of Commerce degree with specialisation in Industrial Psychology.

A lot of challenges

“I had a lot of challenges during my first-year undergraduate studies. I could not afford textbooks and stationery. I spent most of my time in the library studying. More often I would be without food and proper clothes to wear.

“I would get warnings from my landlord when the rent was late. Sometimes I would find my room locked and my personal stuff removed. Not being able to pay outstanding fees restricted me from receiving my final results at the end of semesters and exacerbated the situation,” says Motlhabane.

Regardless of all these challenges, she was determined to not give up and return home to the impoverished community of Itireleng village near Pampierstad in the Northern Cape.

Overcoming the challenges

It was actually the distress, poverty and the difficult situation at home, together with her daily struggles that kept her focused. Through hard work, she managed to receive funding from NSFAS for her second and third years and despite the hardships, she obtained her BSocSci degree with distinction at the end of 2012.

“I was then selected to enroll for an Honours degree in Industrial Psychology in 2013. Without any funding prospects for my studies, I wrote to the former university rector Prof Jonathan Jansen, seeking financial assistance.

“Prof Jansen was very impressed with my exceptional academic performance and offered to pay my fees. He also offered me a position to work as a student assistant. I worked for three hours every day before going to the library to do my assignments and prepare for classes, presentations, tests and exams. I completed my Honours degree in 2013.”

In 2014, Motlhabane was employed as an intern at the UFS Human Resources Department and also enrolled for a postgraduate diploma in gender studies, which she obtained at the end of that year. The following year she joined the postgraduate school and started with her Master’s degree in late 2016.

Obtaining a Master’s degree

This was no easy task as she was employed full time which left her with little time to work thoroughly on her thesis, her limited knowledge about research, work pressures and demands, rejections, lack of support, discouragements, accidents and the inability to cope also played a role.  

“I would like to thank God for the strength he gave me to cope throughout my journey, my family for their prayers and continued support, as well as Prof Jonathan Jansen, Prof Petrus Nel and Prof Ebben van Zyl for their kind support and contribution towards my studies. Indeed, the future belongs to those who believe in the beauty of their dreams,” says Motlhabane.

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.
