Dr Nthatisi Nyembe, a faculty member in the Department of Zoology and Entomology at the University of the Free State (UFS) Qwaqwa Campus, is making notable advancements in the field of parasitology. A native of Qwaqwa, Dr Nyembe embodies the potential for academic achievement within the community she serves, representing a commendable instance of homegrown talent.

A respected graduate of the UFS, Dr Nyembe completed her Bachelor of Science degree in Botany expeditiously before pursuing a Bachelor of Science Honours and Master of Science in Zoology, specialising in Parasitology, all on the UFS Qwaqwa Campus. Her postgraduate studies centred on evaluating medicinal plants for compounds with the potential to treat parasitic gastrointestinal nematodes in sheep – an area of significant importance for the sustained well-being of livestock.

Dr Nyembe broadened her academic horizons by earning a Doctor of Philosophy in Animal and Food Hygiene from the Obihiro University of Agriculture and Veterinary Medicine in Hokkaido, Japan. Her doctoral studies widened her scientific understanding and enhanced her expertise in the treatment of parasitic ailments.

Currently, her research focuses on the evaluation of naturally derived substances, synthesised compounds, and nanoscale particles for their potential efficacy in combating parasitic illnesses. Her broader research interests include pharmacological evaluation, the diagnosis and epidemiology of diseases transmissible from animals to humans, cell biology, and animal management, making her contributions essential to both human and veterinary medicine.

Her academic and research background is extensive. She has held research assistant positions at both the Obihiro University and the UFS, and she also concluded a postdoctoral fellowship at the North-West University in the North West province of South Africa.

Beyond her scholarly pursuits, Dr Nyembe engages in activities such as skiing, travelling, reading, and community involvement, reflecting a well-developed character and a commitment to creating a positive impact beyond the academic sphere.

With her international academic experience and firm local connections, Dr Nyembe continues to be a symbol of distinction, inspiring students and contributing to pioneering research that addresses practical challenges.

Prof Tredoux turns theories regarding the formation of metals on its head

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.
