Prof Motlalepula Matsabisa, Professor and Director of Pharmacology, will play host to the various stakeholders to network and share knowledge on current developments in indigenous knowledge research and product development, biodiversity, innovation, and commercialisation of the IK-based research products. The Indigenous Knowledge System (IKS) for Health unit in the Department of Pharmacology within the UFS Faculty of Health Sciences was last year awarded an annual Technology Innovation Agency Platform (TIA) grant of R17 million for the next five years.
The research and teaching programme in the School of Clinical Medicine has since been rebranded and is now known as the African Medicines Innovation and Technology Development Platform (AMITD), which will strive to respond to community health needs and address industry research needs and challenges.
The indaba will showcase progress made by TIA and other entities in enriching the development and commercialisation of IK-based innovations. It will take place from 24 to 25 November 2022 in the Equitas Senate Hall at the UFS.
Prof Matsabisa is the chairperson of the World Health Organisation’s (WHO) Regional Expert Advisory Committee on Traditional Medicines for COVID-19. He is also a visiting professor at the Beijing University of Chinese Medicine (BUCM) in Beijing, China, and the Deputy President of the South African Society for Basic and Clinical Pharmacology.
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.
