All 23 grade 10 learners taking part in the University of the Free State’s (UFS) Creative Clubs Programme were awarded medals at the Bloemfontein regional Eskom Expo for Young Scientists (EYS) competition from 3 to 5 August 2023.

The learners, who attend Bloemfontein township schools, had been working on their projects for over a year as part of the Creative Clubs Programme, which is run by the UFS Faculty of Education. Guided by veteran Expo facilitators Dr Angela Stott and Coretha van den Heever, they attended 30 sessions on the UFS South Campus, with a total of 140 hours of face-to-face contact time, coupled with many hours of individual work at home, to prepare for the competition.

Their hard work paid off handsomely, with all 23 learners (who worked on 21 projects) achieving medals: six bronze, seven silver, and eight gold. Additionally, five of the learners won best-in-category awards, three won SA Youth Water prizes, and three were shortlisted for the international EYS competition.

“As an introvert, I found it difficult to explain my project to people, but I’ve developed communication skills and confidence through Expo,” said 15-year-old Nicolas Hugo, from Kagisho Secondary School, whose project won a gold medal. Nicolas studied water pollution levels at two inflow sites in the Bloudam catchment area, as well as the dam itself and its outflow, showing the astounding cleaning effectiveness of water reeds.

In addition to his gold medal he won the prize for the best project in his category, a special award in the category of water projects, and for the Best Development Project.

The UFS has a strong commitment to community engagement, and has been working with township schools throughout the province via school-university partnerships for over a decade. The 2023 Bloemfontein EYS competition celebrated the legacy of these partnerships not only through the 23 learners who were directly involved in the UFS programme over the past year, but also through the participation of 14 learners from two schools (Senakangwedi and Setjhaba Se Maketse) in Botshabelo as a direct result of the UFS’s work in those schools in the past. Before UFS ended its partnership with these schools, learners who had been involved in Expo programmes conducted by Dr Stott established science clubs in their schools. These clubs have continued to operate years after UFS exited the schools and the founding learners matriculated. This year these clubs yielded the winning project, Solar Power Stand, by Simthembile Hlahliso and Kabelo Sekoere from Senakangwedi High School.

Many of the learners said they have learned important skills through this process. “I didn’t know how to use a computer, but now I’m so good,” said Sylvia Hlangabeza, who won a gold award.

“I’m so proud of her, I cried,” said Sylvia’s proud mother.

Student excels at international level with research in Inorganic Chemistry

Carla Pretorius completed her PhD in Inorganic Chemistry recently, with a thesis entitled “Structural and Reactivity Study of Rhodium(I) Carbonyl Complexes as Model Nano Assemblies”, and has just received her results. The assessors were very impressed, and she will graduate at the next UFS Summer Graduation in December 2015.

She is currently conducting research in St Petersburg, Russia, by invitation. She is working in the group of Prof Vadim Kukushkin of the St Petersburg University, under a bilateral collaboration agreement between the groups of Prof Kukuskin (SPBU) and Prof André Roodt (Head of the Department of Chemistry at the UFS).

Her research involves the intermetallic rhodium-rhodium interactions for the formation of nano-wires and -plates, with applications in the micro-electronics industry, and potentially for harvesting sun energy. She was one of only three young South African scientists invited to attend the workshop “Hot Topics in Contemporary Crystallography” in Split in Croatia during 2014. More recently, she received the prize for best student poster presentation at the international symposium, Indaba 8 in Skukuza in the Kruger National Park, which was judged by an international panel.

Carla was also one of the few international PhD students invited to present a lecture at the 29th European Crystallographic Meeting (ECM29) in Rovinj, Croatia (23-28 August 2015; more than 1 000 delegates from 51 countries). As a result of this lecture, she has just received an invitation to start a collaborative project with a Polish research group at the European Synchrotron Research Facility (ESRF) in Grenoble, France.

According to Prof Roodt, the ESRF ID09B beam line is the only one of its kind in Europe designed for time-resolved Laue diffraction experiments. It has a time-resolution of up to one tenth of a nanosecond, after activation by a laser pulse 100 times shorter (one tenth of a nanosecond when compared to one second is the equivalent of one second compared to 300 years). The results from these experiments will broaden the knowledge on light-induced transformations of very short processes; for example, as in photochemical reactions associated with sun energy harvesting, and will assist in the development of better materials to capture these.
