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.

Humans need to adapt their thinking to the world’s changes. This is Pieter Geldenhuys’s conviction.

The Information and Communication Technology Services (ICT) at the University of the Free State hosted a seminar on 22 April 2016 at the Bloemfontein Campus. Geldenhuys, the Director of the Institute for Technology Strategy and Innovation at North-West University and internationally-renowned futurist, presented his views on technology, innovation, and corporate management on this occasion.

Geldenhuys, a well- known speaker, academic, and futurist, is in the business of identifying opportunities in the changing technological and social landscape with the aim of assisting companies to prepare for the future, while being an active agent in defining it. Lately, he has been exploring the concept of a new kind of management science, which he believes is a prerequisite for institutions such as ours.

This management science incorporates physics in improving corporate management. “We have an unbelievable grasp of the world of physics,” he said, suggesting that we use our knowledge of nature to capitalise on individual and collective strengths within institutions.

He said that minor changes can change one’s future or that of an organisation completely. He even went as far as to state that the culture of an organisation is the one that determines how well you do. Relating to the adaption of organisations in a constantly changing and dynamic environment, Geldenhuys advised that, “when faced with disruption, don’t retaliate; accept.” 

By making use of different tools, such as technology aw well as social and business trends, Geldenhuys is adamant that corporations and institutions will adapt easily to the world’s complex systems.
