We are pleased to host Bertus Jacobs in our second episode of the Voices of the Free State podcast series. As Chief Technology Officer at IoT.nxt. (Internet of Things), Bertus’ mind is constantly searching for new techniques, and imparting these to his team of developers. Evident from his ‘always on’ approach, Jacobs has optimised his passion for turning ideas into mainstream realities. He co-founded a successful software company, CSS Software, which saw its humble beginnings grow from Bloemfontein-based to an international-footprinted company. CSS Software is regarded as having some of the most innovative products in its market segment and was acquired by a JSE-listed group.

François van Schalkwyk and Keenan Carelse, UFS alumni leading the university’s United Kingdom Alumni Chapter, have put their voices together to produce and direct the podcast series.  Intended to reconnect alumni with the university and their university experience, the podcasts will be featured on the first Monday of every month, ending in November 2021.  Our featured alumni share and reflect on their experiences at the UFS, how it has shaped their lives, and relate why their ongoing association with the UFS is still relevant and important. The podcasts are authentic conversations – they provide an opportunity for the university to understand and learn about the experiences of its alumni and to celebrate the diversity and touchpoints that unite them.

While studying towards his BScHons (Computer Science) at the University of the Free State, Bertus developed an SDK (Software Development Kit) with low-level integration into various graphics hardware.  

Bertus has researched many ways of contributing to the growing IT industry – from developing point-of-sale systems that still run today, qualifying as MCP and MCSE, engineering telematic and biometric solutions for clients (UFS was one of them). After being approached to consult in developing a solution for the government, his search for a certain hardware problem and his expertise in the IT realm resulted in his invention of a controller and the birth of the RAPTOR.  Reports that took eight weeks to compile previously, are now at the fingertips of those who need it – all through data harvesting and dashboarding that combines software and hardware. The world-changing RAPTOR delivers a complete IoT solution, which has been internationally validated as being at the forefront of the emerging IoT wave.  IoT.nxt was named Best Commercial and Best Overall Winner at the MTN Business M2M Awards in 2017.  

Stay tuned for episode three to be released on 5 April 2021.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

17 September 2013

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.
