Peet Jacobs.

Peet Jacobs is no stranger to the Deaf community in and around the UFS and Bloemfontein. He has been working at the University of the Free State (UFS) for the past six years, and he is still amazed at the amount of support our institution provides to Deaf students in particular, and to South African Sign Language (SASL) in general. “They provide excellent interpreting services,” Peet says, “not only in face-to-face classes, but also on different online platforms, as well as interpreting pre-recorded lectures and videos.” And as a SASL interpreter, Peet is an integral part of this service. 

But signing is not merely a day job for Peet. He carries his skill into the community in his spare time, where he assists as an interpreter at hospitals, doctors’ rooms, and psychiatrists’ offices – to name but a few. What gives Peet the deepest satisfaction, however, is when he can combine his love of Sign Language with his love of the Bible and his God. It was actually Peet’s devotion to his religion that inspired him to learn Sign Language in order to enable him to carry the Word of God into the Deaf community. Peet now also presents Bible courses in SASL and assists a non-profit organisation to produce SASL Bible-based publications, which are translated and recorded in video format. 

Peet aspires to become an authority on SASL subject-specific vocabulary related to subject in higher education. “Sign Language is a language in its own right,” Peet points out. “The uniqueness of Deaf culture and the variety of dialects within SASL give the language diversity and colour.” Peet goes on to emphasise how important it is that SASL is recognised as an official language in our country. “This recognition will give dignity to a group of people who have been marginalised in South Africa. This will also pave the way to providing more inclusivity and service to the Deaf community.”

Until then, Peet will continue to serve the best way he knows how: through signing.

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.
