Prestige Lecture by Justice Albie Sachs

Invitation

Who actually wrote the Constitution?

The Dean of the Faculty of Law, Prof Serges Kamga, invites you to a Prestige Lecture which will be delivered by Emeritus Constitutional Court Justice Albie Sachs.

Date: 30 October 2024

Time: 17:30

Venue: Equitas Auditorium

RSVP: Before 20 October 2024 (RSVP here)


Albie Sachs is an activist, writer and former judge on the Constitutional Court of South Africa (1994 – 2009). He began practising as an advocate at the Cape Bar at the age of 21, defending people charged under the racial statutes and security laws of apartheid. After two spells of being detained in solitary confinement without trial, first for five months, then for three months, he went into exile in England, where he completed a PhD at Sussex University. In 1988, he lost his right arm and his sight in one eye when a bomb was placed in his car by South African security agents in Maputo, Mozambique. After the bombing, he devoted himself to the preparations for a new democratic constitution for South Africa. When he returned home from exile, he served as a member of the Constitutional Committee and the National Executive of the African National Congress until the first democratic elections in 1994.

Sachs is a Board member of the Constitution Hill Trust, which promotes constitutionalism and the rule of law. He has travelled to many countries sharing South African experiences that might help heal divided societies.

He is the author of several books, including The Jail Diary of Albie Sachs, Justice in South Africa, Sexism and the Law, Soft Vengeance of a Freedom Fighter and The Strange Alchemy of Life and Law. His latest books are We, the People: Insights of an activist judge (2016) and Oliver Tambo's Dream (2017). He received an honorary doctorate in Law from the UFS in 2022.

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.
