Best assigment winners

The University of the Free State Library and Information Services (UFS LIS) is partnering with faculties in acknowledging top-performing students at the university. Together with the Faculties of the Humanities and Natural and Agricultural Sciences, the Best Assignment project was launched – meant to inspire, motivate, and encourage students to put extra effort into producing assignments of high quality.

Legopheng Maphile, Assistant Director: Library Marketing and Community Engagement at UFS LIS, says the project is meant to harness and nurture undergraduate research in line with the university’s research-led vision. 

“There are requirements as to how assignments should be presented. This demonstrates the level of knowledge acquisition and academic writing skills. The library contributes to this activity by training students in library research skills to access scholarly, academic, specialist, and expert information resources to support academic excellence. This is a collaborative practice between the library and academics.

“In 2019, only third-year assignments were considered in a pilot project, and at this stage, students are expected to understand what is required for writing assignments.”

Recognising the effort that students put into their assignments, the UFS LIS, in collaboration with the Departments of Sociology and Zoology and Entomology, recently handed out prizes of R2 500 to deserving students. 

Johandré J de Haan and Christoffel de Lange each received gift vouchers to the value of R1 250, courtesy of Van Schaik and Sherwood Books, in collaboration with Juta and Oxford University Press. De Haan was recognised for his assignment titled Marx and the impact of his theoretical concepts in the South African context and its relevancy and De Lange received a nod for his Differences in Heat Uptake Rate between White and Black Sand-filled Cans of Similar Size. 

Legopheng says going forward, the best undergraduate research assignments will be considered for publication in the Kovsie Undergraduate Research Journal, the library’s open-access journal that is being developed.

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.
