Martin Nyaka, Secretary General of the 2024-2025 Institutional Student Representative Council (ISRC) and Policy and Transformation Officer (CSRC) on the Bloemfontein Campus of the University of the Free State (UFS), has been elected as Second Deputy Secretary General (DSG) of the South African Union of Students (SAUS)

Nyaka was elected during the first leg of the SAUS conference, held in Gqeberha from 10-13 July 2025. His election is historic, as this is the first time the union has appointed a second DSG. In his new role, he joins the National Executive Council (NEC) alongside the SAUS President, Deputy President, Secretary General, Treasurer-General, and the First DSG.  

“It is a great honour for me to have represented the University of the Free State at this important platform, and I remain deeply grateful for the support and assistance I received from the institution throughout this journey,” said Nyaka. He will serve in this role until the next election in 2028. 

 

Anticipated impact

Nyaka explained that his decision to stand for election was influenced by challenges he and his SRC colleagues encountered when addressing certain student-related issues. He noted that some concerns, such as those linked with the National Student Financial Aid Scheme (NSFAS), can only be resolved at a national level. 

“This position places us in a better position to assist students and to ensure that our students are funded,” he said.  

In addition to his role as Second DSG, Nyaka also chairs the SAUS Monitoring and Evaluation portfolio, which oversees several sub-committees within the organisation.  

 

Lessons from leadership 

As his SRC term draws to a close, Nyaka reflected on the lessons he will carry into this new role. 

“Previously, as student leaders our mindset was very radical, and if ever things would not go our way, we would take to the streets,” he explained. “However, over this last term, the SRC resolved matters and reached agreements with management without protest. An important lesson I take with me is that radicalism is not always the answer. In an organisation like SAUS, we need to sit down and have discussions with stakeholders when there is a deadlock.”

Nyaka emphasised that what excites him most about the opportunity is the chance to work alongside student-leaders from across the country who are equally committed to making a meaningful impact.

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.
