UFS loveLife Computer Graduations
The group of 90 members of the Botshabelo community who successfully completed the 12-week ICT Services short-learning course through a collaboration between the UFS Directorate Community Engagement, the Department of Computer Science and Informatics, and the youth leadership organisation, loveLife.

With the COVID-19 pandemic, many people will look back at 2020 and 2021 with emotions of depression, anxiety, and hopelessness. But for a group of close to 200 community members in Botshabelo, the past two years have not only signified one of their biggest achievements in life; for them, the day that they graduated is also holding the promise of a new beginning.

Both this year’s group and the group of 100 community members who enrolled for the two ICT short learning courses in 2020, successfully completed the programme.

“After 12 weeks of training, the community members were very happy to receive their certificates,” says Alfi Moolman of the Directorate Community Engagement at the University of the Free State (UFS).

According to Moolman, this Information Technology service-learning project is a wonderful example of how the UFS responds to the needs of the community and addresses the digital divide through its Service-Learning programme.

Aiming for 100% digital literacy

Rouxan Fouché, Lecturer in the Department of Computer Science and Informatics who is also doing his PhD in Computer Information Systems, is focusing on the digital divide in his research study, titled: An exploration of service-learning strategies to address the South African digital divide: A Critical Utopian Action Research Approach. He quotes Molawa, who defines the digital divide as the separation of those who have access to digital information and communications technology and those who do not. “Molawa has confirmed that some of the challenges to information and communication technology (ICT) access in Africa have been caused by poverty due to high levels of unemployment, illiteracy, and skills shortage.”

In his study, Fouché states that South Africa is aiming for 100% digital literacy and skills to leverage the power of modern ICT for economic appropriation and to address inequity.

In his investigation, Fouché found that increasing the level of digital skills is the responsibility of many different stakeholders, from governments to universities. “Universities may play a vital role in helping to bridge the digital divide by providing free or affordable access to digital skills training and qualifications focused on groups from marginalised areas.”

He is currently concluding the last phase of his PhD study, which included the implementation of the service-learning action plan with the Botshabelo community – engaging them to strengthen the response to digital literacy.

Equipped with 21st century computer literacy skills

Moolman says they had to think of innovative ways to ensure that students continue to achieve their learning outcomes during lockdown. “A blended learning approach was decided on, where we introduced videos of the sessions that would have been facilitated face to face in the past.”

“As a collective change facilitator in the process, I connected Fouché and loveLife, a youth leadership organisation that has a Cyber Y lab at their youth centre in Botshabelo.”

“The match was a win. loveLife was equipping their target audience with 21st century computer literacy skills, Fouché could continue with his PhD, and his students have achieved their learning outcomes.”

Felix Morobe, the provincial manager of loveLife, believes the skills development opportunities provided by the UFS through their service-learning programmes are benefiting and growing young people in the community.

He says this programme has meant a great deal to the community, as it adds to their CVs. “Moreover, it also carries the logo of one of the best and most well-recognised universities. This course was a big motivation for the members of the community who attended; saying to them, ‘yes you can do it, despite the challenges that the country is facing in terms of youth unemployment’.”

Feedback from some of the attendees of the course, include, “I wish this course could continue and benefit others”; "I am one step ahead of those who did not attend the course"; and "I am going to apply for work now that I have this additional certificate".

“This is a brilliant example of engaged scholarship,” concludes Moolman.

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.
