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 awards honorary degree to Justice Richard Goldstone
2012-01-26

 
Justice Richard Goldstone

A huge honour will be bestowed upon the University of the Free State (UFS) when the world renowned Justice Richard Goldstone will be receiving an honorary degree at the official opening of our university.

The Doctor of Laws (honoris causa) degree will be conferred on Justice Goldstone on Friday 3 February 2012 at 10:00 on our Bloemfontein Campus.

Mr Richard Freedman, Director of the South African Holocaust and Genocide Foundation, and Judge Mahube Molemela, Justice of the Free State High Court, are amongst the prominent figures expected to attend this event.

Justice Goldstone served in the Constitutional Court from 1995 to 2003. Prior to that, he was a judge of the High Court and from 1989 a judge of the Supreme Court of Appeal. From 1994 to 1996 he was the first Chief Prosecutor of the United Nations Criminal Tribunals for the former Yugoslavia and Rwanda. He is presently a Senior Fellow at the Jackson Institute at Yale University in the United States. Over the past 18 years he has become a leading expert on international criminal law.

Prof. Neels Swanepoel, Head of the Department of Law of Procedure and Law of Evidence, said the faculty is proud to honour Judge Richard Goldstone for his outstanding legal career and in particular for his contribution to the development of international criminal justice.

“As Chief Prosecutor for both the International Criminal Tribunal for the former Yugoslavia (ICTY) as well as the International Criminal Tribunal for Rwanda (ICTR), he has contributed to precedent-setting judgments on genocide, war crimes and crimes against humanity. His publications on various aspects of International Criminal Justice have contributed towards the stage where those bearing the greatest responsibility for human and humanitarian rights violations, will face justice.”

Prof. Swanepoel says judge Goldstone has contributed towards laying the foundations for conflict resolution in societies that have transformed from repressive to democratic rule and to what is now referred to as ‘transitional justice’.

On Thursday 2 February 2012 at 19:00, Judge Goldstone will deliver a Prestige Lecture on ‘The Future of International Criminal Justice’ in the Auditorium of the C.R Swart Building on the UFS Bloemfontein Campus.
