Nuclear medicine and green energy focus of international collaboration at UFS

Chemistry — 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.

“At the UFS, we want to produce graduates for the world, and we need to ensure that we use our knowledge to uplift society”
— Prof Francis Petersen, 14th Vice-Chancellor and Rector of the University of the Free State (UFS)

On Friday 19 May 2017, the University of the Free State (UFS) celebrated the inauguration of its 14th Vice-Chancellor and Rector, Prof Francis Petersen. The formal inauguration was held in the Odeion Theatre on the Bloemfontein Campus. The ceremony was preceded by a week-long welcoming programme on the three UFS campuses.

The guest list included representatives from local and provincial government, vice-chancellors and rectors from across South Africa, and senior members of the university’s executive management.

During the inaugural address, Prof Petersen paid tribute to his predecessors for the role they played in making the university what it is today. This included former rectors and vice-chancellors who attended the ceremony, such as Prof Francois Retief and Prof Frederick Fourie, and Prof Stef Coetzee and Prof Jonathan Jansen who were unable to attend.

Prof Petersen characterised 2015 and 2016 as watershed years for the South African higher-education system. “The Rhodes Must Fall, and subsequent Fees Must Fall student and staff protests challenged us, and re-energised a critical engagement around the purpose of the university in an equal society, both as a site of complicity and as a potential agent for social change,” said Prof Petersen.

He committed himself to developing the UFS into an institution that will have an even greater impact than before.

“This institution I am striving to establish will be one that responds positively to inclusivity, diversity, and transformation, and which can incorporate these values into our curriculum, scholarship, and research in a productive way,” said Prof Petersen.

Prof Petersen emphasised the importance of the three-campus model. “The University of the Free State is ONE university with three campuses: the Bloemfontein Campus, our South Campus, and the Qwaqwa Campus. I am committed to align the activities of the three campuses, and to integrate our activities to a greater extent.

“We must work together to infuse each campus with the values we have identified as essential if we are to make our mark as a united University of the Free State: academic excellence, diversity and inclusivity, and innovation.”

The Chancellor, Dr Khotso Mokhele, had the honour of handing over the gown to Prof Petersen. Prof Lis Lange, Vice-Rector: Academic, explained the relationship between the university and the Basotho people, and how this relationship is honoured through the official procession gowns of the UFS. The Basotho blanket is worn by kings, and the university therefore hopes that the symbolism of the gown would be a source of inspiration to Prof Petersen.

The event was concluded by congratulatory messages from former colleagues and the President of the Student Representative Council on the Bloemfontein Campus, SK Luwaca. The event was elegant and graceful – the inaugural address was thought-provoking and inspiring.

Welcoming Ceremonies:

The week of 11-19 May 2017 was one of the highlights in this year’s calendar for staff and students of the University of the Free State (UFS), with various ceremonies taking place to welcome Prof Francis Petersen – who assumed his duties on 1 April 2017 – as the 14th Vice-Chancellor and Rector. The festivities culminated in the official inauguration ceremony at the Bloemfontein Campus on 19 May 2017.

The Qwaqwa Campus welcoming ceremony took place on Thursday 11 May 2017, attracting a wide spectrum of community leaders from the area. Prof Petersen was welcomed by representatives from the two trade unions, National Education Health and Allied Workers Union (Nehawu) and UVPERSU, as well as representatives from the Student Representative Council (SRC), the Thabo Mofutsanyana Education District, and the House of Traditional Leaders. Paramount Queen Mopeli of the Bakoena Royal House bestowed a special honour upon Prof Petersen by clothing him in a traditional Basotho blanket and hat. She said, "From our heart of hearts, welcome, Prof Francis ..., and all Godspeed during your tenure."

The South Campus in Bloemfontein hosted a welcoming ceremony for the new Vice-Chancellor and Rector on 18 May 2017. The ceremony included a number of vocal performances and messages from various stakeholder groups. The same afternoon, the Institute for Reconciliation and Social Justice (IRSJ) also facilitated a panel discussion, titled Diversity, inclusivity, and social justice and the renewed call for decolonisation, in the Albert Wessels Auditorium (AWO) on the Bloemfontein Campus.

The welcoming ceremonies culminated in an event in the Callie Human Centre on Friday 19 May 2017 at the Bloemfontein Campus, with a number of performances by musicians associated with the UFS, marimbas, drum majorettes from Jim Fouche Secondary School, the Grey College Gumboots, and school choirs from Eunice Secondary School, Brebner Primary School, and Willem Postma Primary School. Representatives from key stakeholders such as Nehawu, UVPERSU, the Campus Ministries Forum, SRC, Alumni, Convocation, and the UFS Council had the opportunity to convey their messages of welcome to Prof Petersen.

The formal inauguration ceremony took place in the Odeion Theatre on the Bloemfontein Campus the same day.
