Grassroots Champions Rising Above Challenges

Reciprocity. That’s what it’s all about when it comes to engaged teaching and learning in a community context.  Everyone must benefit – which includes getting recognition for what you’ve achieved,” says Karen Venter, Head of Service Learning in the Directorate: Community Engagement.
   
This conviction was put into practice at the recent Grassroots Community Engagement Awards. It was an opportunity to thank and award all the role players who made a success of this year’s Learning Festival, presented in partnership with Bloem Shelter on the Bloemfontein Campus earlier this year. During the festival, 55 skills development workshops were offered in a collaborative effort to create sustainable income-generating micro enterprises.

Global University for Lifelong Learning graduates

The awards function also doubled as a proper ‘Cap and Gown’ ceremony for 18 participants in the Global University for Lifelong Learning (GULL) programme. For the past three years, they’ve been involved in action learning on a uniquely designed Professional Bachelor Pathway to Holistic Development. This pathway is rooted in spiritual, personal, and professional development, where the learning of skills for entrepreneurship is key to gain personal and professional viability, moving from dependence to independence.

“GULL’s approach is to give people in the community a chance to advance themselves. Our focus is professional and not academic. It’s about life skills and professional skills where people don’t have the funds or qualifications to follow an academic route,” explained Prof Richard Teare, President of GULL, who came all the way form the UK to officiate the ceremony.
  
Academics and Life Skills running parallel

“What makes the UFS involvement in our programme so great, is that it’s run parallel with an excellent academic programme offered by the university.”

He emphasised the importance of graduation ceremonies, as it instilled a sense of pride and gave graduates an opportunity to reflect on how far they’ve come in improving their own circumstances. 

“This is a deep form of learning, because we are enabling people to move from their difficult circumstances and release their own inner potential.”

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.
