The Trio Con Brio ensemble in the Odeion School of Music (OSM) was crowned winners of the open category during the final round of the national SASMT Ensemble competition, which took place on 22 September 2021.  The Trio Con Brio comprises OSM students Kagiso Ramosa (clarinet), Maria Yasbeck (violin), and Karlin Kock (piano).

OSM lecturers, Drs Danre Strydom, Sharon de Kock, and Anneke Lamont served as instructors and mentors during the preparation phase. “The trio prepared their concert programme with an interesting methodology, by having weekly instruction from all lecturers individually on a rotation basis,” says Marius Coetzee, Artistic Director of the Odeion School of Music Camerata (OSMC). Elsabé Raath serves as the principal instructor. 

The OSMC took second place in the concert programme, while the instructor of the OSM Brass Quintet, George Foster, and the convenor, Quinn Kakora, were also selected to participate in the first round of the competition. Their recital was highly ranked and came third in the first round.

 SASMT competition develops young musicians 

The first SASMT Pretoria Ensemble Competition took place in September 2017. It would be the first competition of this nature to be held in the northern region of South Africa. The goal was to create an opportunity for young musicians to compete in groups, rather than focusing on solo performances. The feedback from the initial competition was overwhelmingly positive, culminating in the decision to make it an annual event.

The competition aims to develop young musicians through collaborative participation and by encouraging the enjoyment of performing with others. Another objective is to foster understanding, love, and appreciation for ensemble music and the performance thereof among young musicians.

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.
