Samson Diamond, Jeanne-Louise Moolman, Prof Anmari van der Westhuizen-Joubert, and Sharon de Kock with the QoP instruments created by luthier Brian Lisus to honour SA’s Nobel peace laureates.

Hope, the viola; Freedom, the first violin; Peace, the second violin; and Reconciliation, the cello, collectively known as the Quartet of Peace (QoP), have found their home at the UFS. The Odeion String Quartet (OSQ) has been made the custodians of this world-famous quartet created by Brian Lisus. The instruments were created by Lisus in 2010 to commemorate the four Nobel peace laureates of South Africa, namely Albert Luthuli, Nelson Mandela, FW de Klerk, and Desmond Tutu. In March 2022, Lisus presented a lecture in the Odeion Theatre to officially present these instruments to the UFS.

Many new performing opportunities 

“The trustees found that justice will be done by making the Odeion String Quartet the new custodians, since they are the only quartet-in-residence at a South African university,” says Prof Anmari van der Westhuizen-Joubert, cellist and Head of the OSQ.

As the custodians of the QoP, it brought many new performing opportunities, both nationally and internationally. “It can also be used in presentations of lectures on all subjects and not only of a political nature. In this way, string quartet music reaches more people than just those who go to concert halls,” Prof Van der Westhuizen-Joubert says. The OSQ consists of Prof Van der Westhuizen-Joubert (cellist), Samson Diamond (violinist and leader of the string quartet), Sharon de Kock (violinist), and Jeanne-Louise Moolman (violinist).

Unique part of UFS identity

The uniqueness of the QoP instruments will be an important element of the OSQ, the Odeion School of Music, the Faculty of the Humanities, as well as the entire UFS community. “One of the plans is to raise money to enable students to come and study with the Odeion String Quartet members at the UFS,” Prof Van der Westhuizen-Joubert says. Another historic moment with these instruments took place in October 2022, when the instruments took centre stage at a concert hosted by Prof Francis Petersen, UFS Rector and Vice-Chancellor, at Constitution Hill in Johannesburg. At this event, the QoP instruments were introduced to the public, important stakeholders, and to guests of the UFS. Other plans include trips to international festivals such as the Ojai Music Festival in the USA in 2023 and the String Quartet Biennale in Amsterdam in 2024.

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.
