UFS community engagement contributes to nation building

17 March 2021 | Story Karen Venter

UFS CE infographic 3 copy — As illustrated in the infographic, the input from engaged activities delivered by the UFS resulted in 285 engaged-activity outputs, of which the majority constituted engaged citizenship, followed by engaged research, and then engaged learning and teaching.

At the University of the Free State (UFS), engaged scholarship activities are guided by the vision of being a research-led, student-centred, and regionally relevant university, focused on development and social justice.

For enactment of this vision, the UFS invests physical resources and funding, as well as staff and student hours to contribute to nation building.

Demonstrating the heart of strategic partnerships

Engaged scholarship demonstrates the heart of strategic partnerships, where agreements are grounded in shared goals, designed and agreed upon in unity for socio-economic renewal to improve people’s living conditions, contributing to societal well-being. It links the best of the research and teaching skills of staff and students to specific needs of the community, including civil society, the private sector, government, non-governmental organisations, and enterprises.

Democratic knowledge co-creation emerges from engaged learning and teaching, engaged research, and engaged citizenship through interaction between the institution, its staff and students, and the community.

The curriculum, engaged research efforts, engaged learning and teaching, and graduate attributes are all enriched through collaborative and reciprocal learning activities. As illustrated in the infographic, the input from engaged activities delivered by the UFS resulted in 285 engaged-activity outputs, of which the majority constituted engaged citizenship, followed by engaged research, and then engaged learning and teaching.

Deep understanding of socio-economic and environmental challenges

Our students participate in community-engaged service-learning, leading to knowledge acquisition and a deep understanding of socio-economic and environmental challenges in mutual solidarity with the community. Service-learning also gives rise to the acceptance and understanding of diverse cultures and races and advances the ability to interact meaningfully with diverse people from different backgrounds.

Community-engaged learning increases awareness of own biases and stereotypes along the dimensions of race, ethnicity, culture, gender, sexual orientation, socio-economic status, age, physical abilities, religious beliefs, political beliefs, or other ideologies. By transcending their own comfort zones, combined with collaborative learning with diverse groups, students can gain greater appreciation of the strengths and capacities of diverse groups in the community.

Engaged scholarship also embraces the inculcation of citizenship and the social responsibility of the UFS to society by giving effect to one of the key ‘public good’ dimensions of the UFS.

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.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast 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.
