Prof Prince Ngobeni, newly appointed Campus Principal of the UFS Qwaqwa Campus.
The University of the Free State (UFS) has appointed Prof Prince Ngobeni as Principal of the Qwaqwa Campus as from 1 February 2024.
Prof Ngobeni completed his first qualification in Analytical Chemistry at the then Technikon North-West before furthering his studies at the then Technikon Pretoria. He completed a DTech in Chemistry at the Tshwane University of Technology (TUT) in 2003. In 2016, he enrolled for a Doctor of Business Administration in Higher Education at the University of Bath in England.
His lecturing career began at TUT in 1995 where he progressed from Head of Department: Chemistry in 2003 to Associate Dean: Faculty of Science in 2010, before being appointed as Executive Dean of the Faculty of Sciences at TUT in 2015 – a position he held until 2023. He also served as Interim Campus Rector of TUT’s Pretoria Campus from 2018 to 2020.
“With extensive years of academic leadership experience, Prof Ngobeni has the experience required to guide the Qwaqwa Campus towards the university’s Vision 130. The campus is already recognised as a leader in some of its unique research fields, and Prof Ngobeni’s strong research background will be valuable in this regard,” says Prof Francis Petersen, Vice-Chancellor and Principal of the UFS.
Prof Ngobeni is a member of several professional bodies in his field of expertise, including MatTEK at the Council for Scientific and Industrial Research (CSIR), the South African Chemical Institute (SACI), the Society for Atomic Spectroscopy, and the South African Council for Natural Scientific Professions (SACNASP). During his career, he has also secured research funding for individual projects and international partnerships. Prof Ngobeni also initiated chemistry practical sessions for local schools and participated in the Technology Station in Chemicals project, which offers a wide range of services designed to assist small and medium enterprises (SMEs) in the chemical sector.
His substantial list of publications in journals and books covers a range of chemistry-related and managerial topics. He is also a well-versed presenter at local and international conferences.
“The Qwaqwa Campus has experienced major developments in recent years; I look forward to further contributing to the growth of the campus and to support the university in achieving its Vision 130,” says Prof Ngobeni.
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.
