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 postdoctoral Fellow expands international opportunities for women in Science Communication

Mikateko Höppener, postdoctoral Fellow at the
Centre for Research on Higher Education and
Development (CRHED), University of the Free State (UFS),
who was selected as one of five South African women
to participate in the Best Practice in Science
Communication UK study tour.

“Often, the power lies in our own hands as individuals to take the initiative, be curious about opportunities to learn, develop an interest to make a positive contribution in society through our research, and make use of our networks within and outside of academia to effect positive change.”

This is according to Mikateko Höppener, a postdoctoral Fellow at the Centre for Research on Higher Education and Development (CRHED), at the University of the Free State (UFS), who was selected as one of five South African women to participate in the Best Practice in Science Communication UK study tour. This was part of the British Council and Academy of Science South Africa (ASSAf) women in science project.

Höppener said she saw this as an opportunity to expand opportunities for women in Science, Technology, Engineering and Mathematics (STEM). “The whole experience reinforced my conviction that there is a lot of untapped potential for young people to practise and enhance science communication in South Africa for the betterment of our communities,” she said.

During her visit to the UK, Höppener was exposed to an international networking platform of science communication practitioners and stakeholders such as the Director for Development of Vitae, departments at The Royal Society, science journalists at the BBC World Service, policy advisers and public engagement teams at the Welcome Trust, the Director of SciDev.net, and the Science Adviser for STEM Education and Public Engagement at the British Council.

Höppener said each of these meetings had highly interactive presentations and discussions with members of various organisations and the South African delegation. 

Being selected for the science communication fellowship and attending the study tour was not only personally and professionally rewarding for Höppener, it also enabled her to pass on what she had learnt to fellow emerging women researchers in South Africa.

Earlier this year, she hosted a WiSTEM (Women in Science, Technology, Engineering and Mathematics) Science Communication and Engagement Workshop at the UFS and through press releases and radio interviews, brought positive attention to the UFS to inspire young women across the country to get involved in science communication training.

“I intend to establish a science communication and engagement centre at the UFS where ongoing training, mentorship and support will be offered to young researchers to learn how to orient their knowledge and research to community development through science communication,” said Höppener.

The Best Practice in Science Communication UK study tour took place from 24 to 28 October 2016 as part of the Newton Fund Professional Development Programme South Africa.
