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.

Qwaqwa Campus launches No Student Hungry Programme

The Qwaqwa Campus of the University of the Free State launched the No Student Hungry (NSH) Programme on Friday 26 April 2013. The programme aims to provide needy students with a daily balanced meal to enable them to concentrate in class and ultimately obtain their degrees. The programme – initiated by Vice-Chancellor and Rector Prof Jonathan Jansen in 2011 on the Bloemfontein Campus – already feeds hundreds of students.

Rudi Buys, Dean of Student Affairs who represented the Rectorate, encouraged students in need to focus more on their desire for greatness.

“Through this programme, you will be able you to shift your focus from the hunger pangs and rather focus all your energy on the hunger to make Africa great,” said Buys. “We want you to be different from the rest of your generation that is reluctant to compete for greatness. Many of your peers prefer mediocrity and it is our wish that through this programme, you can start learning to compete with the best,” Buys impelled.

According to the Qwaqwa Campus programme co-coordinator, Selloane Phoofolo, NSH operates on a primary and a secondary level.

“The primary level offers a food bursary to the students whose academic performance is above 65 percent and not receiving any form of financial assistance. For the 2013 academic year, we had 53 students applying and 31 have qualified. They are getting a meal for R25.00 a day at the Dining Hall,” said Phoofolo.

She further explained that, “On the secondary level, we provide monthly food parcels to 19 students who did not qualify for the food bursary. These food parcels are donated by Pick n Pay and Stop Hunger Now SA. For this, beneficiaries must undertake 40 hours of community service during the year. They must also partake in student activities. Their academic progress is monitored by the Office of Social Work.”

One of the beneficiaries, a final-year BA degree student Samkelo Duma, expressed his gratitude towards the UFS for giving him an equal opportunity to those in more fortunate situations to do his best in his studies. “It is difficult to study and concentrate on an empty stomach and I must say that the NSH is very helpful. I do not just get a meal, but I get a healthy meal to keep me going throughout the tough day,” Duma said.

Also present at the launch were the patrons of the programme, Ms Grace Jansen and Dr Carin Buys. They volunteer their time and energy to raise funds for the project.

Students apply for the allowances and are selected on the basis of financial need, academic results, active participation in student life programmes and commitment to give something back to the community.

You can also invest in these students' future by contributing R10.00 each time you sms the word 'Answer' to 38722.
