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.

Postgraduates’ new Kovsies home

Postgraduate students and their academic 'parents' at the University of the Free State (UFS) now have a dedicated physical, emotional and electronic space to provide for their specialised needs in order to further promote research excellence at the UFS.

The university's Postgraduate School was launched in May 2011, but ventured further in the quest to fulfil and expand its mandate with new initiatives. These different aspects of the school were launched on Wednesday 8 May 2013 in the CR Swart Auditorium on the Bloemfontein Campus. The postgraduate strategy, postgraduate prospectus, the website and the headquarters of the Postgraduate School in the Johannes Brill Building were all unveiled and launched.

Prof Driekie Hay, Vice-Rector: Academic, who was a major driving force behind the formation of the Postgraduate School, during her address at the opening emphasised the multifaceted and unique relationships which often exist between students and supervisors.

Prof Hay, who has a distinguished academic background in postgraduate teaching, made plain her expectations for the Postgraduate School. She said it aims to "create an intellectual space for postgraduate students and supervisors" in order to produce world-class intellectuals at this university.

She said the school will empower both students who often don't know what to expect from supervision, as well as supervisors who often lack supervision skills. Through this it will be possible to create healthy, productive relationships between the distinct pairs in often misunderstood, unbalanced and intricate interactions.

Dr Henriette van den Berg, Director of the Postgraduate School, introduced the strategic plan of the school and emphasised the great strides that have already been made and what still needs to be done at the UFS in terms of postgraduate teaching. According to her, the Postgraduate School aims towards "holistic development of postgraduate students with transferable skills," through a multi-level and institution-wide approach at the university.

"Our aim is to develop a one-step service for postgraduate students, involving all the different stakeholders," she said.

The new Postgraduate School website was also showcased during the event. Reachable through a number of avenues on the main website, the site offers a digital version of the Johannes Brill Building. Brimming with features catering specifically for local, international, current and prospective students, the website provides crucial information.

The Johannes Brill Building's refurbished interior, with staff offices, seminar rooms and social spaces, were also showcased to UFS' staff and students. The initial phase of the Supervisors' Wall of Fame was also unveiled. According to Dr van den Berg , the wall will after completion bestow much-deserved praise on a hand-picked group of 60 supervisors who have respectively been responsible for more than 300 and more than 500 successful PhD and master's candidates over the past decade.
