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.

Tough future if nothing changes in Africa
2015-02-20

 

The Department of Political Studies and Governance at the UFS recently hosted a workshop with the Osaka School for International Public Policy and the Southern African Centre for Collaboration in Peace and Security Studies.

The workshop, which was held on Thursday 12 February, had the theme of Perspectives on African Peace and Security. During workshop sessions, thoughts and views on peace and security were discussed for both African and South African circumstances. This was the fourth year of this joint workshop at the UFS.

Prof Hussein Solomon from the Department of Political Studies and Governance at the UFS shared some notes:

“In terms of South Africa, the fact that only 11% of South Africans have a post-school education holds negative prospects for us attaining a so-called ‘knowledge economy’”, says Prof Solomon.

“This also means that unemployment will continue to remain high since, in certain key areas, the South African economy is quite sophisticated, and needs a sophisticated labour force. Therefore, high unemployment translates into further social unrest, especially if one considers that youth unemployment is approaching 50%.”
 
Moving to broader issues in Africa, Solomon states that governance remains a challenge.

“There is a need to move away from Eurocentric forms of governance to more hybrid forms, implementing a mix of western forms of governance alongside more traditional forms.”

“Otherwise, the probability of conflict remains high as we look into the future. The possibility of water wars between African states is distinct.”

“Terrorism too will be with us for some time to come, with three terrorist attacks per day in Africa. Making matters worse, whether it is conflict over water or terrorist atrocities, is the African Union’s inability to resolve these issues. It simply does not have the capacity”, says Solomon.
