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.

Like Idols for scientists
2014-04-10

Kovsie student and scientist Karabelo Moloantoa recently represented the Free State in the South African finals of the FameLab competition during the Sci-Fest in Grahamstown.

Karabelo is a 24-year-old student doing his master’s in Biotechnology. He completed his Bachelor’s degree in Medical Microbiology, as well as his Honours degree in Biochemistry at Kovsies. His research is focused on Bioremediation of mine waste waters.

“FameLab is like the scientists Idols taking place annually,” says Karabelo.

“In the competition we are given three minutes to explain a science aspect to a non-science audience. There are 25 countries that participate. South Africa is the only African country participating.”

“I was called by one of my lecturers an hour before the local competition took place at the National Museum in Bloemfontein. I was actually still tired from playing volleyball the night before,” he explains. “I was unprepared and without slides, but I did my presentation.”

This was the first year Karabelo entered FameLab and although he was somewhat unprepared for the local competition in Bloemfontein, he was nominated to represent the Free State in Grahamstown at the Sci-Fest event. From the 18 semifinalists, Karabelo qualified to go the finals where the 9 finalists were competing to represent South Africa in the United Kingdom for the international finals.

“I did not win the UK trip, but I made it to the finals, which is an achievement as half of the semi-finalists could not make it to the finals,” says Karabelo.

“I feel like I have done well to represent the university and the province as a whole. It was amazing to speak in front of more than 800 people, delivering my presentation. I learnt a lot and improved my skills of communicating scientific aspects. I will definitely enter again next year.”
