First Sesotho soundtrack for fulldome film launched at Naval Hill Planetarium

In December, the Naval Hill Planetarium used the voice of a well-known South African actress for yet another trailblazer: the first Sesotho soundtrack for a full-dome film.

“It is important for our children to become interested in science and astronomy through exposure to good language use in their mother tongue from an early age, so that we can still make a sound contribution to these fields in the future,” said Prof Matie Hoffman from the Department of Physics at the University of the Free State.

Space Shapes, a child-friendly fulldome film by the Ott Planetarium at the Weber State University in Utah in the US, was translated into Sesotho as Dibopeho tsa Sepakapakeng by Khantlapane Selina Ketla and Dr Andries Hoffman, following last year’s release of the short film by the Naval Hill Planetarium as Ruimtevorms in Afrikaans. The film, created by participants of the 2010 Blender Production Workshop in Utah, takes young audiences on a journey to explore the different shapes found in space.

The voice artist, Tshireletso Nkoane, a star in her own right, is best-known for her television roles in the drama series, Tshisa, the comedy series, Moferefere Lenyalong, as well as the miniseries, Naledi. She has several theatre and radio credits to her name, and also boasts a diploma in Electrical Engineering.

The premiere of this Sesotho trailblazer, as well as the CosmoQuest and Ward Beecher Planetarium’s English fulldome film, Cosmic Castaways, will take place at the Naval Hill Planetarium on Saturday 17 February 2018 at 17:30. Cosmic Castaways is an exciting work that reaches out to places where there are no constellations; where there are still isolated stars to be found in the voids between the galaxies.

Tickets for this double premiere, as well as for the weekly Saturday 17:30 shows, are available from Computicket – just search under ‘planetarium’ on the Computicket website or visit Checkers.

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.
