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.

Former Kovsie wins Absa L’Atelier

A former Kovsie has taken top honours at the Absa L’Atelier Art Competition.

Elrie Joubert, who completed her master’s degree at the Department of Fine Arts in 2010, is the first Free Stater who has won the competition for young artists between 21 and 35. This puts her in the company of previous winners such as Penny Siopis and Diane Victor. As the overall winner, Joubert receives a cash prize of R110 000 and a six month stay at the Cité Internationale des Arts in Paris, France.

Her winning entry, Selective Unveiling, consists of a light-table with a private collection of miniature natural objects, a digital microscope used by the viewer to inspect the objects, as well as a projector that projects the microscope’s image directly on a screen.

“By making my private collection public, I expose myself to possible investigation and criticism,” says Joubert about her winning entry. “The process is, however, reversed when the viewer is also robbed of his/her ‘privacy’ in collecting images with the microscope, which are projected on a screen for other viewers to see.”

Joubert, who lectures in Drawing and History of Art of Graphic Design at the Midrand Graduate Institute’s Bloemfontein Campus, says the Absa L’Atelier is the biggest competition she has won thus far. In 2007 and 2010 she reached the final rounds of the SASOL New Signatures Art Competition.

Her advice to art students: “Keep on doing what you do, learn to handle criticism selectively, and above all, if you take no risks you’ll never win.”
