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.

Shimlas still the only unbeaten side in 2015 Varsity
2015-03-18

The Shimlas remain the only unbeaten side in this year’s Varsity Cup rugby tournament after their bonus-point 44-24 win against the University of Cape Town Ikeys in Bloemfontein.

The home side managed a very comfortable 34-8 lead in the first half against the defending champions Ikeys. No matter how hard the Ikeys fought back, the Shimlas win was inevitable, and secured the first ever home semifinal at the UFS.

It was in the second minute that Shimlas’ Gerhard Olivier went over the try line. The Shimlas continued to press forward, and kept the game play primarily in the UCT half of the field. By the time the first Strategy Break came along, the Shimlas already had a 21-0 lead over their visitors. The Ikeys did manage one converted try before halftime, still leaving the home side with  a 34-8 lead.

After halftime, there was still no stopping the Shimlas. Even when UCT’s attempt at a comeback saw them scoring their second converted try, the point difference were still 18 points. Shortly after, Olivier scored his third try for the Shimlas. The Ikeys’ response to this was scoring a third try in their comeback effort, putting the scoreboard at 39-24 with Shimlas still in the lead after 65 minutes.

Despite Ikeys’ attempt for their bonus point try near fulltime, Shimlas’ counter-attack saw their replacement player Boela Venter cross the try line for the last  time to secure a 44-24 win for the home side.

The Shimlas will host North-West University’s Pukke side at Shimla Park in the last round of the tournament this coming Monday. For the first time since the Varsity Cup’s inauguration in 2008, the UFS side has already secured a home semifinal for the week after.

Shimlas point scorers:

Tries: Gerhard Olivier (3), Johan van der Hoogt, Danie Maartens (2), Boela Venter
Conversion kicks: Niel Marais (3)
