Dr Kamohelo Tshabalala, Senior Lecturer in the Department of Physics, shares his UFS journey.

The University of the Free State (UFS) is celebrating Youth Month by showcasing the positive influence of the institution on career development. As part of this initiative, we are sharing the stories of UFS alumni who are now working at the university.

Dr Kamohelo Tshabalala, Senior Lecturer in the Department of Physics, shares his UFS journey:

Q: Year of graduation from the UFS: 

A: 2004 and 2015.

Q: Qualification obtained from the UFS: 

A: BSc in Physics and Mathematics and PhD in Solid State Physics.

Q: Date of joining the UFS as a staff member: 

A: 2003 to 2004 and 2012 to date.

Q: Initial job title and current job title: 

A: I began my journey as a Lab Assistant, but over time, I advanced to higher positions within the academic realm. Presently, I proudly serve as a Senior Lecturer and Subject Head in the esteemed Department of Physics. Additionally, I have taken on the role of acting Assistant Dean in the distinguished Faculty of Natural and Agricultural Sciences.

Q: How did the UFS prepare you for the professional world? 

A: First and foremost, I successfully completed my BSc degree, followed by the attainment of a Doctor of Philosophy (PhD). I firmly believe that these educational achievements serve as a solid foundation for excelling in both teaching and leadership roles.

Q: What are your thoughts on transitioning from a UFS alumnus to a staff member? 

A: It is a very interesting aspect; however, this transition may entirely depend on an individual’s interest in whether to continue with their studies or not. The stimulation may come from the undergraduate teachings that exhibit real interventions for new developments towards empowering the society at large.

Q: Any additional comments about your experience? 
A: As both an academic and a departmental leader for the past nine years, I am very grateful for all the support from the university community. I would encourage young scholars to explore more leadership roles that are available in the sector, because one is always up to date with new initiatives and strategies for the betterment of human and academic projects.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
