Pictured here are the Department of Chemistry graduates and their promoters/ co-promoters.

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.

Postgraduate studies can open doors to a successful career – Top 50 Economics students advised

The Department of Economics in the Faculty of Economic and Management Sciences held a reception for its top 50 students on 10 October 2016 on the Bloemfontein Campus.

Speaking at the event, Mr Rocco Carr, business development manager at Glacier Investments by Sanlam, encouraged students to enrol for postgraduate studies in Economics and Financial Economics. He said the South African economy was not stable at the moment due to various factors such as politics. However, it was interwoven with the global economy and circumstances might change to make the country prosperous again in the future. ”The interest rates, the upcoming presidential election in the US, the economic changes in China, Brexit, and the economic changes in the European Union are some of the factors that are at play in the South African economy,” he said.

He further encouraged students to be prepared for the workplace by developing their work ethic and learning to take responsibility as this would help them grow a successful career despite economic volatility.

Dr Johan Coetzee, acting head of the Department of Economics, said the three honours programmes – Economics, Financial Economics and Investment Management, and Applied Econometrics – were internationally accredited and could open many doors to students. “Training is not only about what you can do, also how you think and how you manage people. Managing people has become more important than ever before,” Coetzee said.

The department hosts its top 50 students each year to expose them to courses they can take at postgraduate level and the career opportunities that lie ahead.
