Discussing progress in green energy and nuclear medicine during the recent ReMec2, were from the left: Dr Dumisani Kama (UFS), Prof Roger Alberto (University of Zurich), Prof Andreas Roodt (UFS), and Dr Orbett Alexander (UFS).
Scientists in South Africa and Switzerland, with a research collaboration of 20 years, are working together to make a difference. A major focus of their work is nuclear medicine and green energy. 

Since the end of October, 22 speakers from five countries met for five days at four different sites in South Africa to discuss their work during the second symposium on reaction mechanisms, better known as ReMec2. The Department of Chemistry at the University of the Free State (UFS) hosted this event. 

Considerable reduction of carbon dioxide

According to Prof Andreas Roodt, lead researcher from the UFS Department of Chemistry, ReMec2 focused mainly on two projects: nuclear medicine and an R8 million project titled: Solar Light-driven Homogeneous Catalysis for Greener Industrial Processes with H2 (hydrogen gas) as Energy Source and CO2 (carbon dioxide) as C1 Building Block. This is a sunlight-driven project in search of new catalysts, which are chemical compounds that make the reactions faster and more effective, but which are not consumed during the reaction. The aim is to provide greener industrial processes with hydrogen as energy source, and to reduce carbon dioxide in the environment.

This research, if applied, has the probability of preventing the release of more than 100 kg of harmful carbon dioxide for every one kg of hydrogen produced. “Together with the Swiss group, we are at that stage of the research where these compounds, with just one molecule of the catalyst, can make 80 000 hydrogen molecules (very clean energy, as hydrogen in a car's engine burns to clean water; not like gasoline that burns to harmful carbon dioxide),” Prof Roodt explains. 

The UFS and the research group from Prof Robert Alberto at the University of Zurich have been working together on this research for the past twenty years. According to Prof Roodt, they are studying complete reaction mechanisms, including the time profile of how the different chemical compounds are reacting with each other and not just the simple product analysis as studied by most groups in the world. 

International patent on nuclear medicine

In June 2019, they registered an international patent on nuclear medicine model compounds. The patent was granted. During ReMec2, a lecture was presented on this patent, according to which a compound with an imaging isotope [Tc-99m] that has its own ‘X-rays’, can shed light on an affected organ in the human body for doctors to see where medicine should be administered. The same compound also contains the medicine to treat the disease. 

The work of these scientists is 100% in line with South Africa’s National Development Plan and it supports the UFS Strategic Plan. “The programme also builds on students’ research and increases network and collaboration possibilities. We receive more international acknowledgement for our research efforts and compete with the best in the world. Our research is not necessarily about having the best equipment (although it is very important), but critically it is about the generation of innovative ideas,” says Prof Roodt.

UFS on the right track with transformation - Fulbright scholars

“I think the university is not only on the right track but can really become a model for how to negotiate certain difficult processes, such as transformation, within a short period of time. I think it can become a model, not just for other universities, but also for the world.”

This was said by Dr Rozetta Wilmore-Schaeffer, who together with Rev. Dr Frederick J. Streets, recently worked with the International Institute for Race, Reconciliation and Social Justice at the University of the Free State (UFS) as Fulbright specialists. They helped the institute come up with ideas in terms of making the changes that are necessary for the transformation of the university.

“There is a great deal that has already been done despite the sense of urgency and impatience, and I think there is a great deal more to be done,” said Dr Wilmore-Schaeffer.

“I think this sense of urgency comes from those who are involved in the process of looking at the destination, the place that they want to be at, and feeling that they are very far from it.”

During their visit here the two had numerous conversations with both staff members and students.

“I have been most impressed by the students who I think are ready to make changes in many different ways – I am talking about students of all racial groups and gender. The fact that they are referring to transformation as ‘their struggle’ shows that they are prepared to make changes,” said Dr Wilmore-Schaeffer.
She, however, cautioned that there were those who were still against transformation taking place at the university.

“I think there is still some resistance from some quarters on both sides of the fence and I would expect that at this point in time. I think what is really hopeful is that there are so many students who are ready to make the changes, who are making the changes, who are struggling with issues around making the changes; and I think that is really the hope for the university and the hope for the future,” she said.

“The resistance is complex,” added Rev. Dr Streets. “It is around a fear for the future, the loss of identity on the part of both black and white students, and the desire for cultural continuity amongst white students as well as amongst a variety of ethnic black students.

“The resistance is about learning that you are not the only kid on the block anymore and how you then overcome the feeling of realising that you are not the dominant person anymore and that your culture is not the dominant culture anymore.”

They have given a preliminary report of their findings to the Rector and Vice-Chancellor of the UFS, Prof. Jonathan Jansen, which will be followed by a more detailed report later on.
