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 appoints Jansen as rector
2009-03-15

The Council of the University of the Free State (UFS) is pleased to announce that it has agreed to offer the post of Rector and Vice-Chancellor of the UFS to internationally renowned academic Prof. Jonathan Jansen, making him the first black Rector and Vice-Chancellor of the institution in its 105-year history.

This decision was taken by an overwhelming majority, signalling the commitment of the UFS to continue as a world-class university that will at the same time pursue the objective of transformation in the interests of the entire university community.

Announcing the decision today (Friday, 13 March 2009), the Chairperson of the UFS Council Judge Faan Hancke said the UFS was privileged to have had candidates of the highest calibre apply for the position. An international executive search agency specialising in academic appointments had assisted the UFS Council in its search for top quality candidates.

“This has been a truly vibrant, transparent and participatory selection process, which has resulted in our institution being able to make this historic appointment,” said Judge Hancke.

“I appeal to the entire UFS community, staff, students and alumni to support the new Rector and Vice-Chancellor in his endeavour to lead this institution to greater heights. This is an important moment in the life our institution. We should celebrate this achievement as a united university community,” Judge Hancke said.

“As a council we are now unanimously behind Prof. Jansen and want to assure him of our full support,” Judge Hancke said.

In response to his appointment, Prof. Jansen said it was a great privilege and that he would really do his utmost best to be of service to the UFS.

In his statement of intent which was submitted earlier as part of his application for the post, Prof. Jansen indicated that if appointed he “would be deeply honoured to lead one of South Africa’s great universities”.

“The University of the Free State has gained a national reputation for three things: [1] its turnaround strategy in terms of financial stability in a context where external funding has been uncertain; [2] its research strategy which has seen a steady and impressive growth in research outputs; and [3] its managerial decisiveness in the wake of the Reitz incident,” Prof. Jansen said.

Regarding the challenges facing the UFS, Prof. Jansen said in his statement of intent: “The UFS has to find a way of integrating classroom life while at the same time ensuring the promotion of Afrikaans, an important cultural trust of the institution, as well as Sesotho and other indigenous languages. It has to bring academic staff, administrative staff, workers, students, as well as the parent community behind a compelling vision of transformation that works in the interest of all members of the university community. And it has to rebuild trust and confidence among students and staff in the mission of the university.”

Prof. Jansen is a recent Fulbright Scholar to Stanford University (2007-2008), former Dean of Education at the University of Pretoria (2001-2007), and Honorary Doctor of Education from the University of Edinburgh. He is a former high school Biology teacher and achieved his undergraduate education at the University of the Western Cape (BSc), his teaching credentials at UNISA (HED, BEd) and his postgraduate education in the USA (MS, Cornell; PhD, Stanford).

He is also Honorary Professor of Education at the University of the Witwatersrand and Visiting Fellow at the National Research Foundation.

His most recent books are Knowledge in the Blood (2009, Stanford University Press) and his co-authored Diversity High: Class, Color, Character and Culture in a South African High School (2008, University Press of America). In these and related works, he examines how education leaders balance the dual imperatives of reparation and reconciliation in their leadership practice.
