Dr Karen Venter
Dr Venter received her PhD at the December graduation ceremonies. She focused on addressing societal challenges through the practice of engaged scholarship in community-university research partnerships for the common good.

When asked what inspired her to pursue a PhD, Dr Karen Venter, Head of the Division of Service Learning in the Directorate Community Engagement at the University of the Free State (UFS), said she wanted to make a difference in addressing societal challenges through the practice of engaged scholarship in community-university research partnerships for the common good. 

“Also, I love to learn and share knowledge – and that is exactly what I did in this PhD, titled: An integrated service-learning praxis approach for flourishment of professional development in community-higher education partnerships.” 

She explains, “My five-articles-style thesis explored the contribution of an integrated service-learning praxis approach towards the flourishment of engaged scholarship in community-higher education partnerships. The approach combined community engaged service-learning (CESL), appreciative inquiry and appreciative leadership, to advance the praxis of engaged scholarship. The study was demarcated in the field of higher education, applied in the discipline of nursing education, and contextually bound to three interrelated action research cycles and settings – for international, national, and local level engagement.”

Community members participate in the research journey

“The intent of the study was to recognise the community-led action learning of community member participants at the core action learning set,” says Dr Venter. 

The study followed a participatory action learning and action research methodology. During her research journey, she was joined by members of the community, specifically from Bloemshelter – a shelter for the homeless. “They co-constructed and completed a four-year community-led action learning pathway to holistic development (spiritual, personal, professional), which brought about holistic social change and well-being in their livelihood, moving from dependence on others to establishing viable multiple micro-enterprises,” she says.

The UFS affiliated with GULL to reward the community member participants’ action learning. “Already in 2019, GULL certified their action learning with a Professional Bachelor’s degree, while I still had to document the action research, and only now received the PhD,” says Dr Venter. 

“I am grateful to all the participants who co-created action-oriented knowledge with me in the study, from international, to national, to local level of engagement.”

Integrating a PhD with work and life

A PhD requires a lot of hard work and effort, to the point that the lines between studies, work, and life become blurred. Dr Venter acknowledged that she tried to balance work/life and study, but “I was not very good at it”. 
Passion, patience, peace, perseverance, positivity, and prayer are good principles to maintain when you are in the process of completing a PhD. – Dr Karen Venter 

She elaborates, “Studying became an integrated part of my work and life.  For the duration of my studies, I started working at 03:00 and I also did not watch any television.” She did, however, make time for herself by joining the wellness workout programme presented by the UFS, enjoyed gardening, and playing with her grandchildren. “I also tried to rest one day over weekends, and made time to praise and worship, which energised me for the next week,” she adds. 

“Passion, patience, peace, perseverance, positivity, and prayer are good principles to maintain when you are in the process of completing a PhD, she believes. 

Dr Venter says that although writing a PhD is indeed lonely, it is also an exciting journey, “especially when you reach those moments of breakthrough that can only come to life after deep reflection.” She also describes it as a deep spiritual journey. “Almost like walking in and out of a labyrinth – and where many hours become equal to a breath.

She is very grateful to her supervisors, Dr Somarie Holtzhausen, Prof Mabel Erasmus, and Dr Elanie Myburgh. “I deeply honour and salute you for your unconditional and continuous coaching, compassion, and care – guiding, supporting, motivating, mentoring, and keeping me grounded until I completed the journey.”

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.
