The Centre for Environmental Management (CEM) at the University of the Free State (UFS), in collaboration with Dr Dirk Jungmann from the Technical University Dresden, recently presented a virtual summer school on Blackboard, titled: Monitoring of surface water quality: General framework, tools and implementing disaster management aspects in urban areas. 

The international group of 30 persons who attended the summer school mostly comprised postgraduate students and employees from, among others, the UFS and other tertiary institutions such as the Technical University Dresden (TUD), the Cape Peninsula University of Technology (CPUT), UNISA, the University of the Western Cape, Stellenbosch University, the University of Lesotho, and the University of Zimbabwe. Members of the Council for Scientific and Industrial Research also attended the summer school.

Experts present

Dr Marinda Avenant, Senior Lecturer in the CEM, believes the summer school provides students with a wonderful opportunity to be exposed to a topic, such as aquatic biomonitoring, over and above their normal postgraduate studies. “The presenters are all experts in their field and come from a range of disciplines (from hydrology and chemistry to the social aspects of water), as well as from different countries and perspectives,” she adds. 

Some interesting topics covered during the summer school included a panel discussion on water management challenges in Southern Africa. Head of CEM, Prof Paul Oberholser, participated in this live discourse. In 2021, he won the NSTF-Water Research Commission (WRC) Award for his contribution to water resource management in SA over the past five years.

Also contributing a perspective on surface water quality was affiliated professor in CEM, Prof Anthony Turton, who delivered the keynote address on Managing surface water quality as an element of disaster management in urban areas.

Dr Alice Ncube from the UFS Disaster Management Training and Education Centre (DiMTEC) presented on women and disasters (including a case study on a stokvel in Botshabelo), and Dr Inga Jacobs-Mata from the International Water Management Institute (IWMI) provided a social perspective on the water resources sector. 

Students excel 

Five master’s students representing the UFS, the Technical University Dresden (TUD), as well as the Cape Peninsula University of Technology (CPUT), assisted with the organisation of the summer school. The Volkswagen Foundation in Germany, which funded a first summer school in 2019, provided funding that was used to appoint the five students.

According to Dr Avenant, they made provision for the appointment of these students in their project proposal to the Volkswagen Foundation. “The students played a key role in the planning of the virtual summer school; they specially came up with ideas to make the virtual sessions more interesting,” she says.

Among others, they managed the technical aspects of the sessions, introduced the speakers, arranged social activities for the virtual platform, and they produced podcasts. The podcasts of the speakers were distributed to the participants over the extent of two months, in order to learn more about the presenters. 

“We were really impressed with the work of the students, who are all from the natural sciences,” says Dr Avenant.

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.
