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.

The Faculty of the Humanities and Centre for Africa Studies rewarded the contributions of Dr Lakhdar Brahimi, a prominent global peace leader, with an honorary doctorate on Thursday 2 July 2015.

The conferment formed one of the highlights of the 2015 Winter Graduations. Dr Brahimi’s work as a United Nations’ (UN) envoy, and African peace leader of note, was deeply respected by the university. Professor Heidi Hudson, Director of the Centre for Africa Studies at the UFS, accepted the PhD on his behalf.

In his acceptance speech, read by Prof Hudson at the Chancellor’s Dinner the same evening, Dr Brahimi expressed his gratitude to the university. “I deeply appreciate your generous recognition, and even now, in the twilight years of my life, I shall try to be worthy of your confidence in everything I say or do.”

“My generation did its share: its successes and its failures are things of the past. We must accept to be judged by you, the graduates. You, the young graduates here at the University of the Free State, and your fellow members of the African intellectual elite, have an exciting opportunity to take on the challenges and fulfil the dreams you have. We must accept to be judged by you.”

Algerian-born Dr Brahimi was first involved with the UN in 1992 as rapporteur to the Earth Summit. Distinctively, he is the most-frequently appointed special envoy of the UN. Amongst many other countries, he has worked as a mediator for South Africa, Haiti, Afghanistan, Iraq, Syria, Democratic Republic of Congo, Cameroon, Burundi, Angola, Liberia, Nigeria, Sudan, and Côte d’Ivoire on behalf of the UN.

Significant peacekeeping efforts in South Africa (1993- 1994)

The ambassador– in his capacity as special representative to South Africa from December 1993 to June 1994 –played a direct role in South Africa’s democratic transition.

Prof Hudson expressed appreciation for the ambassador’s role in facilitating a peaceful transition from South Africa’s Nationalist government into the current democratic dispensation.

“One of the reasons we selected him as recipient of the honorary doctorate, is because of what he did for the African continent,” she said.

In addition, she commented Dr Brahimi for being a living testament of Ubuntu. “He has displayed an ethic of humanism in everything that he has done, in the way that he has mediated in certain conflicts - his main contribution is as a mediator.

According to Hudson, his humility, modesty, and generosity are the epitome of Ubuntu which states that “I am because we are.”

Dr Brahimi as a global peace practitioner

Dr Brahimi served as Undersecretary-General of the Arab League, Arab League Special Envoy for Lebanon, and Foreign Minister of Algeria.

The UN Peace-building Commission was established as a result of recommendations in his2000 Report of the Panel on United Nations Peace Operations (Brahimi Report).

Since 2007, Dr Brahimi has been a member in The Elders - an alliance chaired by Kofi Annan -of peace and human rights advocates including Desmond Tutu, Graça Machel, Mary Robinson, and Jimmy Carter. His passion for justice led to his membership in the Commission on Legal Empowerment of the Poor.

In 2010, he was Laureate of the Special Jury Prize for Conflict Prevention, awarded by the Chirac Foundation (France), which promotes international peace and security.

Dr Brahimi’s influence in Peace Education

The Brahimi Report has had an indelible impact on scholars specialising in the broad field of peace operations. Dr Brahimi’s writings have also contributed to knowledge on post-conflict reconstruction and development (PCRD), a signification part of the African Union’s narrative.

He is a distinguished senior fellow at the Centre for the Study of Global Governance at the London School of Economics. He has taught a postgraduate course on Conflict Resolution at Sciences Po, Paris (2011); is Andrew D. White Professor-at-Large at Cornell University; and is affiliated to the Institute for Advanced Studies at Princeton, where he was a visiting professor from 2006 to 2008.

In addition, Dr Brahimi is a founding member of the French-language Journal of Palestine Studies, and a board member of the Stockholm International Peace Research Institute.
