Every year, several of our staff and students are involved in projects in our community to make a positive difference. One of the projects where we are making a difference is at Bloemshelter.
I am because you are. Ubuntu. What better month do we have to celebrate our Ubuntu, our South Africanness, than September – Heritage Month. 

South Africans are known for their warm and generous spirit, their humanity. Closer to home, here at the University of the Free State, this is also a reality. 

Bettering the lives of others

Numerous staff members and students engage in community projects and partnerships. “As a regionally engaged university, the UFS supports development and social justice through the practice of engaged scholarship,” says Karen Venter, Head of the Division: Service Learning within the Directorate of Community Engagement.

Engaged scholarship occurs at the heart of community-university partnerships in close and co-operative interaction with several organisations in broader society for the common public good.

A few of the flagship partnership projects that come to mind are Bloemshelter (caring for the homeless and developing as a social enterprise); Towers of Hope (caring for the vulnerable and transforming the city); and the Princess Gabo Foundation (in Thaba ‘Nchu, where they obtained a zero teenage pregnancy rate in school with a simulating doll-parenting programme to initiate responsible reproductive health education). 

In Qwaqwa, Community Engagement partnerships involve the Itemoheleng Soy Project and the AGAPE Foundation for Community Development. Here, the development focuses on nutrition to boost people’s immune systems – especially during the COVID-19 pandemic. According to Moodi Matsoso from the Directorate: Community Engagement on our Qwaqwa Campus, the AGAPE Foundation is manufacturing rosehip juice, which helps with digestion and the healing of ulcers. 

Bishop Billyboy Ramahlele, Director of Community Engagement, is also passionate about sharing knowledge and skills regarding enterprise development to others, supporting them to reach their full potential with the building of tiny houses. 

According to him, an estimated 3 000 of our students are spending at least 127 000 hours per year engaging in the community through 73 academic service-learning modules, excluding the engagement of student organisations such as the Enactus UFS and co-curricular KOVSIE ACT (Active Civic Teaching) residential schools projects.

Vegetables for the food insecure

Another project that is making a difference not only in the lives of our students, but also for food-insecure families, is the UFS Community Garden Project. 

Kovsie ACT, in collaboration with Student Affairs and the university’s Centre for Sustainable Agriculture, Rural Development and Extension (CENSARDE), is running a project where they provide fresh vegetables, including cabbage, carrots, beetroot, kale, and peas to food-insecure families. 

Heritage Month is an ideal opportunity for everyone to show their Ubuntu spirit. Get involved and share some of your time, your talents, and your treasures to improve the lives of others.  There are several causes in Bloemfontein and Phuthaditjhaba that need support (clothes, food, blankets, toys, funding). 

You saw what some of our colleagues and students are doing. What are you doing to make a difference in communities?

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.
