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.

An incident-free recess for the UFS
2010-07-19

The improved security measures at the University of the Free State (UFS) have resulted in an incident-free recess on the Main Campus in Bloemfontein during the 2010 FIFA World Cup and the annual Volksblad Arts Festival.

The UFS provided accommodation for international spectators visiting the country for the World Cup and recently also hosted the hugely popular Volksblad Arts Festival without any security glitches.

These successes could be attributed to the hard work of staff members from various divisions at the UFS to ensure that the security was improved.

“The main question we had to deal with was: should our Main Campus be fenced off? This matter had been under discussion for quite some time. In order to ensure the feasibility thereof, a second impact study was done by a consulting engineer,” said Prof. Niel Viljoen, Vice-Rector: Operations at the UFS.

“This study has shown that, given the nature of activities on the campus and the access configuration, it would be difficult, if not impossible, to effectively control access to the campus, especially as far as visitors were concerned. Any type of access control measure would result in delays at the gates, which could have a major impact on the traffic flow, delays, costs and emissions.”

“It is important that our staff and students feel safe on the Main Campus, whether they are walking on campus or working in their offices. In that way we can ensure an environment that is conducive to staff and students to work and study,” he said.

Various measures are being implemented to make the campuses safer. These include, among others:

  • The installation of alarms in buildings on the Main Campus. The project for the South Campus has been completed and the installation of a new alarm system on the Qwaqwa Campus will start soon.

     
  • Staff and students will be required to wear identification cards once the new identification system has been put in place. These cards will allow access to all buildings.

     
  • Fences around the Main Campus are being repaired and the areas around these fences are being cleaned. This project should be completed by August 2010.

     
  • Lights will be installed in badly lit areas on the Main Campus. The first phase of this project includes the area between the Mooimeisiesfontein, Welwitschia and Vergeet-my-nie residences. This project will also be completed by August 2010.

     
  • The walkways on the Main Campus will be patrolled more frequently and effectively.

     
  • Contracted security workers will be utilised more effectively.

     
  • The monitoring of security cameras on the Main Campus on a 24/7 basis. “For this purpose the security room of our Protection Services is in the process of being upgraded,” said Prof. Viljoen.

The possibility of placing security cameras and panic buttons in parking areas and walkways is investigated.
