The University of the Free State is pleased to present the second Bram Fischer Memorial Lecture, which will be delivered by award-winning biographer and professor of English literature, Stephen Clingman. Well-known author and advocate Tembeka Ngcukaitobi will respond. 

The lecture, titled Bram Fischer, Or What Happens When the World Becomes Inhospitable, will consider the continuing importance of Bram Fischer in a South African and global context. Bram Fischer was born in Bloemfontein in 1908 into one of the most prominent of Afrikaner families. While never surrendering his Afrikaner identity, he also transformed it by identifying with the struggle for liberation of all South Africa’s peoples. Sentenced to life imprisonment, he faced an inhospitable world, yet his commitment was to make the world more hospitable to all. 

Date: Wednesday 11 October 2023
Time: 18:00 to 21:00
Venue: Equitas Auditorium, Bloemfontein Campus, UFS

RSVP here to attend this lecture by 6 October 2023.

The Speaker

Stephen Clingman is Distinguished University Professor of English and former Director of the Interdisciplinary Studies Institute at the University of Massachusetts Amherst. He has held several fellowships internationally and written widely on a range of topics. His books include The Novels of Nadine Gordimer: History from the Inside, The Grammar of Identity: Transnational Fiction and the Nature of the Boundary, Birthmark (a memoir/autofiction), and William Kentridge (the catalogue of Kentridge’s exhibition at the Royal Academy of Arts, 2022). His biography, Bram Fischer: Afrikaner Revolutionary, was co-winner of the Sunday Times Alan Paton Award, South Africa’s premier prize for non-fiction.

The Respondent

Tembeka Ngcukaitobi is a South African lawyer, public speaker, author, and political activist. He is a member of the South African Law Reform Commission. Ngcukaitobi has authored the books The Land Is Ours: South Africa's First Black Lawyers and the birth of Constitutionalism and Land Matters: South Africa's failed land reforms and the road ahead.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

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.
