Muhammad Cassim, a second-year student in the Department of Engineering Sciences in the Faculty of Natural and Agricultural Sciences at the University of the Free State, will participate in the winter university project in Pskov, Russia, from 25 November to 9 December 2024.
The winter school aims to strengthen relationships among young engineers and deepen international interaction via skills improvement, joint projects, and social cohesion. The programme boasts a densely packed education block, project block, and cultural block.
Cassim is part of the UFS Grid Related Research Group and actively participates in research centred on complexity science. He intends to complete his BSc Physics degree with Engineering subjects and progress towards postgraduate studies in the UFS Department of Physics.
He is currently working on verifying experimental developments in the field of synchronisation in complex networks. While he has already completed this high-performance computing training in his first year under the leadership of Albert van Eck (Director, UFS E-research), he is looking forward to the masterclasses in holographic modelling, deep learning, direct laser deposition, and database. Closely resembling his current research, he will have the opportunity to gain more experience in the use of set theory and graph theory in solving digital information processing problems.
For more information about international scholarships for study abroad opportunities, contact Mbali Moiketsi in the Office for International Affairs.
Cassim’s student profile is the culmination of the department’s strategy to produce young applied scientists who are subjected to the culture of research during their undergraduate study and could articulate with ease to other departments for postgraduate studies. The department aims to align with the UFS’ Vision 130 by producing competitive students who can operate in the postgraduate paradigm with the digital themes of veterinary science and ecological engineering science.
Prof Tredoux turns theories regarding the formation of metals on its head

Prof Marian Tredoux 17 September 2013 |
The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.
The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.
This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.
Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.
The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.
For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.
“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”
Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
