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 can lead SA in race relations - Ramphele

The University of the Free State (UFS) could well be a perfect model of excellence in race relations that the whole of South Africa could emulate.

This was said by Dr Mamphela Ramphele, the first African to be a Managing Director of the World Bank, during the Anti-Racism Network in Higher Education (ARNHE) Colloquium held at the UFS recently.

“Healing circles need to be constructed on this campus to address issues raised by the Reitz incident,” she said.

“You might yet be the pioneer of what needs to happen on a nation-wide level.

“Can we confidently commit today to go on this quest for a true humanity and walk together as fellow citizens and strive for a more human face for our society? That is our challenge. That is what the UFS is called to give leadership to.”

“It is this human face which has the power to liberate us from the body of death and strengthen us in our struggle for meaningful life together in South Africa,” added one of the main speakers, Dr Allan Boesak, a cleric and former anti-apartheid activist.

However, said Dr Ramphele, this could only be achieved if all South Africans, black and white, abandoned the fear for each other that was hindering, if not stalling, progress in this regard.

“Fear of each other is the most important impediment to the sustainability of our journey into a society united in our diversity,” she said.

“People in this country are afraid to stand up and be counted, including many vice-chancellors and clerics. They are afraid of being seen to be difficult, and that is a major problem. Fear is the most destructive emotion that you can have because it makes you really incompetent and unable to respond to challenges.”

She said the biggest impediment, though, to ending racism was denial. “White people deny vehemently that they are or have ever been racist,” she said.

“We need to go through a process of acknowledging our wounds and scars from our racist past and present missteps in public policy.”

“Instead of saying they are sorry, those who are conscious of their whiteness should rather say what they are sorry for,” said another main speaker, Prof. Dennis Francis, the Dean of the Faculty of Education at the UFS.

On the other hand, according to Dr Boesak, blacks were and still are, to a large extent, also to blame for their own ongoing oppression. “The key here was the acknowledgement of our sheepish timidity, our complicity,” he said.

The Chairperson of ARNHE, Prof. Norman Duncan, had this to say: “If we are to confront and eradicate racism in higher education institutions, we should not do so to create comfort zones for ourselves.”

The theme of this ARNHE Colloquium was Black consciousness and those conscious of their whiteness. It was presented by the International Institute for Studies in Race, Reconciliation and Social Justice at the UFS.
