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.

Alumni Voices heralds in festive season with Karl Jenkins production
2013-11-20

The Alumni Voices Chamber Choir, affiliated to the Alumni office of the University of the Free State, heralds in the festive season with a Christmas production with the Drakensberg Boys’ Choir.

Date: 23 and 24 November 2013
Time: 19:30 (23 November 2013)
16:00 (24 November 2013)
Venue: Odeion
Cost: R120

The production by the two choirs, under the direction of Leona Geldenhuys (Alumni Voices) and Johann van der Sandt (Drakensberg Boys’ Choir), is a compilation of new Christmas music by Karl Jenkins.

Two cycles, Stella Natalis, made up from new compositions, and Joy to the World, compiled from well-known traditional Christmas music, are combined in this production.

Stella Natalis (Star of Birth or Star of Origin) celebrates the different aspects of Christmas – Celebro – celebrations, Lullay – the sleeping child, Dona nobis pacem – message of peace, and Jubilate Deo – thanksgiving, forms part of the programme.

The part: JOY TO THE WORLD also includes traditional Christmas music. This fresh and vibrant arrangement of In dulci jubilo, Go Tell it on the Mountain, Silent Night, O Jesu so sweet, Son of Maria and The Virgin Mary had a Baby boy, all new arrangements by Karl Jenkins, promises to be an exciting experience.

This work, which conveys the Christmas message of peace, goodwill and compassion, as well as new beginnings, evokes a colour palette of sound filled with exciting musical inspiration.

The work was written for mixed choir, as well as for an optional choir suitable for children’s voices, trumpet soloist, keyboard, percussion and string ensemble.

The trumpet soloist is Paul Loeb van Zuilenburg, with Johan Cromhout as pianist. Members of the Free State Symphony Orchestra complete the picture.
