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.

The Olympic Games – then and now
2012-05-04

4 May 2012

The first victory at the Olympic Games in the little Greek town of Olympia was recorded in the year 776 B.C. For the next 1 000 years, athletes congregated to compete at Olympia every four years in August/September.

The 27th modern Olympic Games will commence in London, England on 27 July this year. Counting from 1896, the year of the first modern Olympic Games, this year’s Games should have been the 30th. However, the Games did not take place three times: In 1916 during the First World War and again in 1940 and 1944 during the Second World War.

Prof. Louise Cilliers of the Department of Classical and Near Eastern Studies will look at certain aspects of the ancient Olympic Games and compare them with the nature of the items and the records of today in a lecture titled “The Olympic Games – then and now” on Tuesday 8 May 2012.

Numerous questions will be discussed, such as what the nature of the records are that were held in the absence of stop watches and standard distances, why the games were held in August/September from the start, what the differences are between ancient and modern items, where all the symbols that have become associated with the Olympic Games came from, and if Baron de Coubertin was right in his glorifying of amateur sport during the ancient times.
