Five PhDs for Chemistry group at June 2018 graduation
Pictured here are the Department of Chemistry graduates and their promoters/ co-promoters. From the left are: Dr Alebel Belay, Dr Dumisani Kama, Dr Orbett Alexander, Dr Pennie Mokolokolo and Dr Pule Molokoane; back: Prof Andreas Roodt, Dr Marietjie Schutte-Smith, Dr Alice Brink and Dr Johan Venter. Prof Roodt was either promoter or co-promoter to four of the graduates, while Prof Deon Visser (promoter; not present) and Dr Alice Brink (co-promoter) supervised Dr Orbett Alexander.
What is the common factor among metal extraction from mineral reserves, the treatment of cancer, and nanomaterials in cellular phones? The answer is Chemistry. 

For the first time since the Department of Chemistry at the University of the Free State (UFS) was founded some 114 years ago, a single research group in Chemistry delivered five PhD students.  This was achieved in the division of Inorganic Chemistry at the 2018 Winter graduation ceremony by the group under leadership of Prof Andreas Roodt and senior colleagues, Drs Johan Venter, Alice Brink and Marietjie Schutte-Smith. Prof Deon Visser, a former group member, was promoter for one of the students. 

The five graduandi are Drs Alebel Belay, Dumisani Kama, Pennie Mokolokolo, Pule Molokoane and Orbett Alexander. Their research involved the use of special chemical groups which are attached to metals such as platinum, rhodium, niobium, technetium and rhenium to create compounds with special pre-selected properties. 

The combination of these special groups with the metals allow many different potential applications – all adding value. These include metal extraction from South Africa’s rich mineral reserves, the treatment of diseases such as cancer, the diagnosis of heart and brain damages, nanomaterials which are used in cellular phones, catalysts to produce cleaner petrol, special light devices which by themselves ‘glow in the dark’, and more. 

Three of the students completed part of their research in Switzerland.

We must rise again, says Dr Luescher

Dr Thierry Luescher, Assistant Director of University of the Free State Directorate for Institutional Research and Academic Planning, was one of the guest speakers at the first TEDxUFS event of the year on the Bloemfontein Campus. Here he is explaining where the #movements started, and how to change the way we think. Photo: Marli du Plessis.

The student protests, known as the #MustFall movements, started on 9 March 2015, when students protested in a well-rehearsed manner at the Cecil John Rhodesstatue at the University of Cape Town. After this protest, students all over South Africa started their own movements from #OpenStellies to #SwartsMustFall, the latter happening on the Bloemfontein Campus of the University of the Free State (UFS) in March 2016. But, as Dr Thierry Luescher, Assistant Director of UFS Directorate for Institutional Research and Academic Planning, says: “We shall soon run out of #MustFalls. Maybe it is time that we rise again.”

The first TEDxUFS was held on Friday 15 April 2016 at the New Education Building on the Bloemfontein Campus of the UFS. Dr Luescher shone light on the way we look at hashtag movements. At the conference, he was one of the guest speakers who shared their perspectives on the theme of #ImpossibleIsNothing. The others were Ndumiso Hadebe, and Fezile Sonkwane.

Changing angles

No matter what the issue, whether it is on a campus or not, the same reaction can be expected by all: they burn things to get attention. In retrospect, this is our political culture. This is what we have been told to do if we need answers. There is a much faster and cheaper way to attract people’s attention: the hashtag movements, says Dr Luescher.

Stop the fire

He argues that we should stop burning down buildings and vandalising properties. What we need is people with intellect to use their words. We, as students, have to take back our voice. We need to stop this self-pitying, and take a stand.

Students have the power to change lives. We would be able to reach as many as 1.4 million people with our tweets or instagram accounts. According to Dr Luescher, the time for violence has come to an end.
