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.

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
