According to Prof Gerhard Bosman (bottom left), the biggest advantage of the COIL exchange for Architecture students was their cultural and online collaboration development while addressing urban diversity, multiplicity, and complexity in the built environment. During an online engagement between academics, were from the left: Prof Mark DeBoer and Prof Chiara De Santi; and bottom, right: Prof Carlo Citter.

In South Africa, student exchange programmes – especially at undergraduate level – remain extremely limited. The national Policy Framework for Internationalisation of Higher Education in South Africa, however, makes internationalisation of the curriculum mandatory and directs that it ‘must not negate curriculum transformation imperatives which higher education institutions in South Africa have an obligation to fulfil'.

The University of the Free State (UFS), through its Office for International Affairs, coordinates the iKudu project, which seeks to transform curricula through internationalisation and virtual exchanges. iKudu, a Capacity Building for Higher Education (CBHE) project, is funded by the European Union’s Erasmus+ programme with EUR999 881 (approximately R20 million) and is implemented over a three-year period. Partner universities in the project are the South African Central University of Technology, Durban University of Technology, University of Limpopo, and University of Venda, with the University of Antwerp, Amsterdam University of Applied Sciences, The Hague University of Applied Sciences, Coventry University, and the University of Siena the European partners in the project.

The dream

According to Cornelius Hagenmeier, Director of the UFS Office for International Affairs, at least 50 academics and 5 250 students from South Africa and Europe will participate in the project through the collaborative online international learning (COIL) exchange model. Academics are receiving training on accredited courses in a virtual setting where the classrooms (each located in a different country or cultural setting) of two or more higher education institutions are linked, working with colleagues from partner universities to implement COIL virtual exchanges for the benefit of their students. 

He says: “Students with different cultural and geographical perspectives and experiences have the opportunity to learn from each other through cross-cultural dialogue, bringing a global dimension to the course content. Apart from developing the intercultural competence, technological skills, and the ability to work in groups, students also enhance their employability.”

Another major advantage of this model is that it gives effect to the South African Policy Framework by contributing to internationalisation at home through purposeful integration of international and intercultural dimensions into the formal curriculum. 

Hagenmeier believes that, besides a transformed curriculum at all partner universities, this process will also influence policy development at national and regional level.  

The opportunity

BArchHons students from the History of Urban Settlement module in the UFS Department of Architecture are but one example of a group of students who benefited from the exchange programme. UFS associate professor and researcher in Earth Architecture, Prof Gerhard Bosman, collaborated with academics from Italy, Japan, and the USA to engage with 85 students across four continents. 

From the University of Siena, Italy, Prof Carlo Citter, an associate professor in Medieval Archaeology, participated in the programme. He was joined by Prof Mark deBoer, a lecturer from the English for Academic Purposes (EAP) programme at the Akita University in Japan, and Prof Chiara De Santi, an assistant professor of Modern Languages, teaching film and cultural courses in English and Italian at the Farmingdale State College in the USA.

Prof Bosman says the COIL exchange programme, which started on 12 April 2021, was executed in three parts. He shares his account of the nine-week journey: “After students introduced themselves on Padlet, they were divided into twelve teams to collaborate in groups of seven to eight students (while creating a digital presence on Google Drive) to discuss, explore, and reflect on the urban environment and the portrayal of society during war/the aftermath of a war as depicted in a selected main steam film. Six weeks later, the groups had to submit final video and slide presentations on these topics. In the last part of the exchange programme – where students benefited from the perspectives of academics in four different cultures – a group and individual assessment reflecting the course discipline of the four student groups had to be accommodated. 

Overcoming challenges

The process unfortunately also had its challenges. Due to the time difference at most of the institutions, students found it difficult to meet. They also had to overcome the language differences, since not all students at the four institutions were English first-language speakers. However, the use of Google Meet (an online tool) with its English caption function helped individuals to follow the text from English voices.

As academics and students worked through the challenges, Prof Bosman confirmed that the COIL exchange programme has significant advantages. He states that the biggest advantage of the COIL exchange for Architecture students was their cultural and online collaboration development while addressing urban diversity, multiplicity, and complexity in the built environment. 

A follow-up COIL exchange between the four new partner universities in 2022 is well underway in the development and planning phases.

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.
