The UFS presented a number of special awards during the graduation ceremonies on its Bloemfontein Campus on 27 and 28 June 2019. 

Jannie de Villiers earns UFS Chancellor’s Medal

Chief Executive Officer of Grain SA and recipient of the 2019 Chancellor’s Medal, Jannie de Villiers, is a renowned leader in the agricultural and food sectors, nationwide and globally. He started his career as an economist for the South African Department of Agriculture in 1985, and dedicated more than 30 years of his knowledge, skills, and leadership to the agricultural sector, specifically in grain-industry development. 
Mr De Villiers is commended for a number of initiatives he has implemented to enrich people’s lives throughout his career. One of his many admirable achievements is equipping upcoming farmers with the necessary knowledge and practical skills to advance crops and establishing a sustainable livelihood for South African citizens in the process.

UFS Council honours Elzmarie Oosthuizen

Council Medal recipient, Elzmarie Oosthuizen, is the Director: Centre for Excellence in Teaching and Learning in the UFS Faculty of Natural and Agricultural Sciences (NAS). 
Oosthuizen’s experience and leadership in foundation and bridging programmes are exceptional. She has successfully initiated a programme to promote teaching and learning in Mathematics, Natural Sciences, Economics, and Agricultural subjects. Due to her active involvement in managing foundational and bridging programmes for students who do not meet the minimum requirements for mainstream higher-education degrees in NAS, the pass rate of the BSc bridging programme has increased from 34% to 83%. 

“This award inspires me to sustain my efforts and find extraordinary solutions for the challenging and complex scenarios that we are facing in higher education,” said Ms Oosthuizen. 

UFS June graduation Dean’s Medal recipients

Michelle Nöthling (Master of Arts in Africa Studies) in the Faculty of the Humanities and Megan Braithwaite (Master of Arts in Theology with specialisation in Bible Translation) in the Faculty of Theology and Religion were awarded Dean’s Medals on the morning of 28 June 2019. The Faculty of Education also honoured Deborah Lynn Fair, who achieved the best results for her master’s degree in Education with specialisation in Curriculum Studies, with a Dean’s Medal.

On the afternoon of 28 June, Teboho Mooko (Master of Medical Science with specialisation in Pharmacology) received the Dean’s Medal in the Faculty of Health Sciences. Tshanduko Mutandanyi (Master of Science majoring in Geohydrology) received the Dean’s Medal in the Faculty of Natural and Agricultural Sciences, as well as the Senate Medal for the best overall results in both under- and postgraduate qualifications in all the UFS faculties.

Dr Khotso Mokhele hosts Chancellor’s Dinner

Later that evening, the Chancellor of the UFS, Dr Khotso Mokhele, hosted the Chancellor’s Dinner in the Centenary Complex on the UFS Bloemfontein Campus, paying tribute to the outstanding achievements of the recipients of UFS honorary doctorates, Council and Chancellor’s medals, and doctorates. 

Among the honoured guests were the two honorary doctorate recipients, Dr Jerry Mofokeng wa Makhetha – world-renowned, respected television and theatre actor (DLitt Honoris Causa – Faculty of the Humanities), and Dr Bernie Fanaroff (DSc Honoris Causa – Faculty of Natural and Agricultural Sciences), who is the Co-chair of the BRICS (Brazil, Russia, India, China and South Africa) Working Group on Information and Communication Technologies and High-Performance Computing, and member of the Advisory Committee of the Breakthrough Listen project; Mr Jannie de Villiers; Ms Elzmarie Oosthuizen; the Rector and Vice-Chancellor of the UFS, Prof Francis Petersen; and Mr Willem Louw, Chairperson of the UFS Council.

Guests also enjoyed a musical performance by the Graduation Instrumental Ensemble under the direction of Anton Esterhuyse, accompanied by the vocal ensemble of Thabo Hlongwane, Jacobus Silwer, and Mario Lategan.

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

 

Prof Marian Tredoux
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.
