Residence members who led the project, included:
Bohlokwa Rantja, the Residence Prime, and Transformation Committee members Nsuku Mutemela, Ofentse Motlakeng, Phindile Tjale, Madinku Mabala, Mmapopi Motshoso, Karabo Shuping, and Tagane Sekete.
The University of the Free State (UFS) Council approved and adopted Lehakwe House as the new name for the
NJ van der Merwe residence on the Bloemfontein Campus. The approval on 26 November 2020 followed a lengthy process of deliberation, consultation, and public engagement that has taken place since November 2019 and is aligned with the UFS Policy on Naming and Renaming. The name-change process was initiated by the Prime and Transformation Committee of the residence, guided by the
Unit for Institutional Change and Social Justice and supported by a multi-stakeholder committee representative of the residence, the Housing and Residence Affairs Office, the Department of Student Affairs, the Student Representative Council, and alumni.
Lehakwe – a precious gem
Following a lengthy evaluation process of the names submitted through a public voting and recommendation platform in July 2020, ‘Lehakwe’ – a Sesotho word referring to a ‘precious gem’ – emerged as the front runner. As many current and past members of the residence attest, this womxn’s residence has come to occupy a significant space within the hearts and minds of UFS students and the UFS community, given that its spirit has always been closely aligned with the constitutional values of dignity, equality, and freedom and with the human values of ubuntu. In this vein, the new name of ‘Lehakwe’ presents a consolidation of constitutional and university values into the day-to-day thinking, learning, living, and legacy spaces of students, as well as everyone who interacts and engages with the UFS.
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.
