Mineral named after UFS professor
Tredouxite (white) intergrown with bottinoite (light grey), a complex hydrous alteration product. The large host minerals are nickel-rich silicate (grey), maybe willemseite, and the spinel trevorite (dark grey).

More than five thousand minerals have been certified by the International Mineralogical Association(IMA). One of these minerals, tredouxite, was recently named after an academic at the University of the Free State (UFS). 

Tredouxite was named after Prof Marian Tredoux, an associate professor in the Department of Geology, to acknowledge her close to 30 years’ commitment to figuring out the geological history of the rock in which this mineral occurs. The name was chosen by the team which identified the new mineral, consisting of Dr Federica Zaccarini and Prof. Giorgio Garuti from the University of Leoben, Austria, Prof. Luca Bindi from the University of Florence, Italy, and Prof. Duncan Miller from the UFS. 

They found the mineral in the abovementioned rock from the Barberton region in Mpumalanga, in May 2017.

In the past, a mineral was also named after Marie Curie
With the exception of a few historical (pre-1800) names, a mineral is typically named either after the area where it was first found, or after its chemical composition or physical properties, or after a person. If named after a person, it has to be someone who had nothing to do with finding the mineral.

Prof Tredoux said: “As of 19 September 2017, 5292 minerals had been certified by IMA. Of these, 81 were named after women, either singly or with a near relation. Marie Curie is named twice: sklodowskite (herself) and curite (plus husband). Most of the named women are Russian geoscientists.”

Another way to assess the rarity of such a naming is to consider that fewer than 700 minerals have been named after people. Given that there are by now seven billion people on the planet, it means that a person who is granted a mineral name becomes one in 10 million of the people alive today to be honoured in such a way. To date, over a dozen minerals had been named after South Africans, three of them after women (including tredouxite).

It contains nickel, antimony and oxygen
The chemical composition of tredouxite is NiSb2O6 (nickel antimony oxide). This makes it the nickel equivalent of the magnesium mineral bystromite (MgSb2O6), described in the 1950s from the La Fortuna antimony mine in Mexico.  

“This announcement is of great academic importance: the discovery by the Italian team of a phase with that specific chemical composition will undoubtedly help me and my co-workers to better understand the origin of the rock itself,” she said. She also expressed the hope that it may raise interest in the Department of Geology and the UFS as a whole, by highlighting that world-class research is being done at the department. 

The announcement of this new mineral was published on the International Mineralogical Association Commission on New Minerals, Nomenclature and Classificationwebsite, the Mineralogical Magazine and the European Journal of Mineralogy.

UFS gives recognition to excellent researchers
2004-11-16

p>The University of the Free State will give recognition to excellent researchers at UFS on Tuesday 16 November 2004. “This recognition function will also serve as the first annual lecture in research excellence,” says Prof Frans Swanepoel, Director of Research Development Division at the UFS.

 

This is the first occasion of its kind in the UFS. It coincides with the university’s centenary celebrations. The recognition of excellent research shows the UFS’s commitment and innovative focus on research as one of its core functions,” says Prof. Swanepoel.

Recognition will be given in different categories. They are female researchers, black researchers, young researchers, C- and L-Rated researchers, researchers with significant research outputs, B-Rated researchers and distinguished professors in research.

The promotion of equity and development of research capacity of designated groups is one of the objectives of the UFS’s research strategy therefore the university is recognising the research achievements of 21 women and 16 black persons. Amongst these are Prof. Margaret Raftery (English and Classical Languages), Dr Liesl van As (Zoology and Entomology), Prof. Peter Mbati (head of the Qwaqwa campus) and Prof. Charles Ngwena (Constitutional Law and Philosophy of Law).

The UFS is also recognising nine young researchers. They must hold a doctorate and have the potential to establish themselves as researchers within a five-year period based on their performance and productivity as researchers during their doctoral studies and/or early post-doctoral careers. Amongst them are Dr Esta van Heerden (Microbial Biochemical and Food Biotechnology) and Prof. André Jooste (Agricultural Economics).

Fifty-eight established researchers with a sustained recent record of productivity are receiving recognition in the C- and L-rated researchers’ category. Amongst them were Prof. Hennie van Coller (Afrikaans, Dutch, German and French) and Prof. Gert Erasmus (Animal- and Wildlife- and Grassland Sciences).

Prof. Francois Tolmie (New Testament) and Prof. Gina Joubert (Biostatistics) are two of the twelve researchers that are receiving recognition for having excelled in research outputs during recent years.

Nine researchers are acknowledged in the B-category for the international recognition they receive from their peers for the high quality and impact of their recent research outputs. Amongst them were Prof. Johan Grobbelaar (Plant Sciences) and Prof. Hendrik Swart (Physics). Prof. Grobbelaar focused in his research on limnology, algal biotechnology, plant stress and Prof. Swart focused on solid state physics and degradation mechanisms that are responsible for the degradation of field emission and TV displays.

Seven individuals are recognised for their exceptional achievements as researchers. Prof. Frederick Fourie, Rector, but previously in the Department of Economics, is recognised for his research in two policy areas: Political Economics, Government Finance and Fiscal Policy, and Industrial Economics, in particular analysis of the South African industrial structure and competition policy, where his research contributions played a key role in reforming South Africa’s competition policy.

Prof. Lodewyk Kock (Microbial, Biochemical and Food Biotechnology) focuses in his research mainly on pure and oxidised edible oil where yeasts are used as a study model. He obtained national as well as international recognition for this research program.

The UFS is also awarding the S2A3 Bronze Medal to recognise a Master’s degree student who has delivered outstanding research in one of the sciences. Mr Pieter Taljaard and Ms Tania Venter are recognised in this category.
