The Faculty of Natural and Agricultural Sciences held its very first virtual Academic Awards Ceremony this year, where 103 prizes were awarded in 75 different categories. Prof Danie Vermeulen sponsored the award for the best undergraduate student in the faculty.

The Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) presented its very first virtual Academic Awards Ceremony this year, celebrating the achievements of students.

According to Tracy Isaacs and Heidiry White, both from the Office of the Dean: Natural and Agricultural Sciences and organisers of the event, the aim of this event is to award and reward skills, knowledge, talent, and abilities. They believe the event contributes to encourage, inspire, and motivate other students to excel.

“Academic awards in the faculty create meaningful moments of recognition that inspire others and reinforce the behaviour that led to the reward. Rewarding students for their hard work forms an integral part of creating a competitive spirit among students. Competition is essential, as it encourages every student to do their best to stand out,” says Isaacs. 

Support and innovation

During this year’s ceremony, 103 prizes were awarded in 75 different categories. Dedicated academic staff who went the extra mile to ensure that no student was left behind, played a major role in the faculty awarding this number of prizes. 

The quality of the programmes and the curriculum, together with innovative teaching and learning activities and approaches, form the basis for academic excellence in the faculty. Lecturers and students are also provided with ongoing support and proper resources to maintain a high quality of teaching.

An achievement that stood out was the work of Philip Schall, who received the Dean’s Award for best undergraduate student in the faculty. Schall obtained his degree with distinction. The Dean, Prof Danie Vermeulen, sponsored this award.

Search for knowledge encouraged

Lecturers and researchers encourage students on a daily basis to pursue academic excellence by challenging them to obtain the highest level of success in their work. 

Students are also provided with an academic, creative, and enterprising spirit that not only prepares them for their academic journey, but also for the world of work. “While being exposed to a range of valuable and relevant learning experiences, students are prepared for further study, ongoing learning, and for their future work environment,” says Isaacs.

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.
