WomenOfKovsies Dr Hoppener research affects access of rural youth to university
Dr Mikateko Höppener is also the author of a book titled, Engineering Education for Sustainable Development: A Capabilities Approach, which is based on her PhD research.

Since September 2016, Dr Mikateko Höppener and a team of researchers have been engaged in a four-year long investigation of the multidimensional factors and dynamics that influence low-income learners’ opportunities to access, participate, and succeed in higher education.

Dr Höppener is a Senior Researcher at the university, working under the leadership of Prof Melanie Walker, South African Research Chairs Initiative (SARChI) Chair and Director of the Higher Education and Human Development Research Programme.

Women in academia

Dr Höppener is part of a team comprised of women whom she constantly learns from and who inspire appreciation.. “I am filled with gratitude for being in the position I am in as a young woman. I have the privilege of working with a team of very inspirational, motivating and encouraging women. The Miratho Project is led by a woman and the rest of the team members are also women,” she says.

Access to higher education
The Miratho Project is undertaken in collaboration with Thusanani Foundation, a youth-led, nonprofit organisation. It is funded by the Economic and Social Research Council, and the UK’s Department for International Development. Rural and township learners from low-income backgrounds are the subject of this multimethod, longitudinal study which tracks their progress into higher education and through to employment.

Among its key objectives, Miratho aims to develop a multidimensional learning outcomes index as an instrument of public debate and guiding government policy. As such it contributes to transforming and decolonising higher education.

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.
