Virtual Exchange
UFS NAS Students participating in the HSWT Online course: Soyama Nonkotwane, Emma Witten, Chris Sambo and Rorisang Modibedi.

Five undergraduate students from the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) - Chris Sambo, Angelique Strydom, Soyama Nonkotwane, Rorisang Modibedi and Emma Witten - have embarked on an online semester at Weihenstephan-Triesdorf University of Applied Sciences (HSWT) in Bavaria, Germany. Running from 1 September 2025 to 14 March 2026, this initiative marks an important step in advancing UFS’s commitment to inclusive and transformative internationalisation.  

The exchange is made possible through an active Memorandum of Understanding (MOU) between UFS and HSWT, which continues to strengthen academic collaboration. 

Reflecting on the opportunity, Prof Corli Witthuhn, Professor in Sustainable Food Systems and Development, highlighted that the opportunity for undergraduate students at the UFS to attend the International Online Semester offered by HSWT greatly contributes to their professional development. “The programme provides education and training in agriculture with a focus on improved farming practices. Students gain not only new insights and skills but also experience an international classroom and work environment. This opportunity allows our students to internationalise without the expense of travelling, serving as an excellent example of internationalisation at home.” 

 

Building digital fluency and intercultural competence 

Virtual exchanges such as this extend beyond academic mobility; they are strategic interventions that foster two vital skill sets for the 21st century: digital fluency and intercultural communicative competence. 

Prof Lynette Jacobs, Interim Director at the Office for International Affairs added that this valued collaboration with HSWT demonstrates the University of the Free State’s commitment to embedding inclusive internationalisation at every level of our academic offering, in diversified ways. “Virtual exchanges provide scalable, equitable opportunities for students to develop the digital and intercultural competencies needed in today’s interconnected world.”   

In an era of rapid technological advancement, students must be able to navigate digital platforms, collaborate across borders, and engage meaningfully with diverse perspectives. 

“I am grateful for the opportunity to broaden my studies through a different institution. For me, this experience opens the door to further studies abroad, and with that knowledge, I want to contribute to the betterment of South Africa,” expressed Emma Witten, one of the participating students. 

 

Skills gained through the exchange 

Through this online semester, UFS students will acquire practical digital skills, including: 

  • navigating international learning management systems,
  • participating in synchronous and asynchronous virtual collaboration,
  • using digital tools for research, presentations, and communication,
  • managing time and tasks in a cross-cultural virtual environment.

They will also strengthen intercultural competencies by:

  • engaging in dialogue with peers from diverse cultural and academic backgrounds,
  • practising respectful communication across cultural norms,
  • reflecting critically on global issues from multiple perspectives,
  • developing empathy and adaptability in diverse learning contexts.

 

Preparing students for global opportunities 

Study abroad opportunities - whether virtual or physical - are a vital part of preparing UFS students for success in a global context. They expose students to different academic systems, build adaptability and resilience, and cultivate leadership and problem-solving skills valued in the workplace. 

For many, these experiences serve as steppingstones to postgraduate study, international research collaboration, and global employment opportunities. This initiative directly supports the vision outlined in the Vice-Chancellor’s Installation Address, demonstrating institutional agility by showing how virtual exchanges can be flexible and scalable tools for internationalisation. 

As these five students embark on their virtual semester, they are not only engaging with new academic content but also stepping into a transformative learning experience. They will sharpen their digital skills, deepen intercultural understanding, and gain competencies increasingly vital in a globally connected, technologically driven world. 

Prof Witthuhn added that the Faculty of Natural and Agricultural Sciences is proud of the students and hopes that they will share their experiences and knowledge with peers and staff in Agriculture. “We believe that the Online Semester will also better prepare them for future employment.” 

This exchange reflects the UFS’s strategic commitment to Institutional Agility and Transformational Culture, ensuring students are equipped for both academic excellence and meaningful participation in a digitally connected world.

Link between champagne bubbles and the UFS?

What is the link between the bubbles in champagne and breakthrough research being done at the Mayo Clinic in America? Nano research being done at our university.

Prof. Lodewyk Kock of Biotechnology says a human being consists of millions of minute cells that are invisible to the eye. The nano technology team at the UFS have developed a technique that allows researchers to look into such a cell, as well as other microorganisms. In this way, they can get an idea of what the cell’s “insides” look like.

The UFS team – consisting of Profs. Kock, Hendrik Swart (Physics), Pieter van Wyk (Centre for Microscopy), as well as Dr Chantel Swart (Biotechnology), Dr Carlien Pohl (Biotechnology) and Liza Coetsee (Physics) – were amazed to see that the inside of cells consist of a maze of small tunnels or blisters. Each tunnel is about 100 and more nanometres in diameter – about one ten thousandth of a millimetre – that weaves through the cells in a maze.

It was also found that these tunnels are the “lungs” of the cells. Academics doing research on yeast have had to sit up and take notice of the research being done at the UFS – to the extent that these “lungs” will appear on the front page of the highly acclaimed FEMS Yeast Research for all of 2013.

The Mayo Clinic, in particular, now wants to work with the UFS to study cancer cells in more detail in order to fight this disease, says Prof. Kock. The National Cancer Institute of America has also shown interest. This new nano technology for biology can assist in the study and development of nano medicine that can be used in the treatment of cancer and other life threatening diseases. Nano medicine uses nano metal participles that are up to one billionth of a metre in size.

Prof. Kock says laboratory tests indicate that nano medicine can improve the efficacy of anti-cancer medicine, which makes the treatment less toxic. “According to the Mayo Clinic team, nano particles are considered as a gold cartridge which is being fired directly at a cancer tumour. This is compared to fine shot that spreads through the body and also attacks healthy cells.”

“This accuracy implies that the chemotherapy dose can be lowered with fewer side effects. The Mayo Clinic found that one-tenth of the normal dosage is more effective against pancreas cancer in this way than the full dosage with a linkage to nano particles. According to the clinic, this nano medicine could also delay the spread of cancer,” says Prof. Kock.

The nano particles are used as messengers that convey anti-cancer treatment to cancer cells, where it then selectively kills the cancer cells. The transport and transfer of these medicines with regard to gold nano particles can be traced with the UFS’s nano technology to collect more information, especially where it works on the cell.

“With the new nano technology of the UFS, it is possible to do nano surgery on the cells by slicing the cells in nanometre thin slices while the working of the nano medicine is studied. In this way, it can be established if the nano medicine penetrates the cells or if it is only associated with the tiny tunnels,” says Prof. Kock.

And in champagne the small “lungs” are responsible for the bubbles. The same applies to beer and with this discovery a whole new reach field opens for scientists.
