Study Bug Bites Historian Early
Prof Corene de Wet, South Campus researcher, is a dedicated historian and educator.

From a childhood dream of being a historian, to a decades-long educator and double doctorate-holder, Prof Corene de Wet has led an eventful life. Realising that her undergrad qualification on its own would not get her a job, she completed the Higher Diploma in Education at the then Potchefstroom University for Christian Higher Education. However, “just to buy some time for myself,” she decided to study part-time while teaching in Winburg.

Prof De Wet calls it “being bitten by the part-time study bug.” By 1991, she had obtained her BEd (an honours degree at the time), MEd, and DEd degrees. In 1999, she graduated with a PhD in History. Today, Prof De Wet is still a research associate on our South Campus.

Tremendous milestones and mentors

Dr Lynette Jacobs, co-researcher on several projects, says, “Prof De Wet was the first woman to receive a full professorship in the Faculty of Education, and the first woman in the faculty to obtain an NRF rating. She received her professorship at a time when the academic world belonged to men. She outclassed her peers, rising head and shoulders above the crowd.”

Prof De Wet says her superhero is Prof Daniella Coetzee, South Campus Principal and long-time colleague. “Prof Coetzee is a brilliant academic and organiser. She makes every member of her staff feel special. I am ever thankful that she saw the need for a researcher on the South Campus and that she appointed me in this position,” says Prof De Wet.

“She is a seasoned academic who
still enjoys international recognition.”

Generational history and work ethic

Although much has changed in education since her initial research, Prof De Wet believes that both her doctoral dissertations still bear scrutiny. Regarding the zeitgeist and its impact on the written history of a nation, Prof De Wet says, “We regularly hear many voices today who say that history must be ‘rewritten’. My thesis dealt with exactly that: How different generations of historians wrote histories influenced by the spirit of the time, or by textbooks, or by their own political or world views, or their philosophy on life. Thus, different generations interpret the same events differently.”

During a career spanning more than four decades, Prof De Wet has upheld a strong work ethic. This has enabled her to maintain her C-rating as an NRF researcher. “If one doesn’t dare, if you are too afraid of critique or failure, you won’t get anywhere in academia,” she says, adding, “Criticism is part of academic life. Therefore, take chances, and learn from healthy, constructive criticism.”

NRF grants of millions for Kovsie professors

Two professors received research grants from the National Research Foundation (NRF). The money will be used for the purchase of equipment to add more value to their research and take the university further in specific research fields.

Prof Martin Ntwaeaborwa from the Department of Physics has received a R10 million award, following a successful application to the National Nanotechnology Equipment Programme (NNEP) of the NRF for a high-resolution field emission scanning electron microscope (SEM) with integrated cathodoluminescence (CL) and energy dispersive X-ray spectrometers (EDS).

Prof Bennie Viljoen from the Department of Microbial, Biochemical and Food Biotechnology has also been awarded R1,171 million, following a successful application to the Research Infrastructure Support Programme (RISP) for the purchase of a LECO CHN628 Series Elemental Analyser with a Sulphur add-on module.

Prof Ntwaeaborwa says the SEM-CL-EDS’ state-of-the art equipment combines three different techniques in one and it is capable of analysing a variety of materials ranging from bulk to individual nanoparticles. This combination is the first of its kind in Africa. This equipment is specifically designed for nanotechnology and can analyse particles as small as 5nm in diameter, a scale which the old tungsten SEM at the Centre of Microscopy cannot achieve.

The equipment will be used to simultaneously analyse the shapes and sizes of submicron particles, chemical composition and cathodoluminescence properties of materials. The SEM-CL-EDS is a multi-user facility and it will be used for multi- and interdisciplinary research involving physics, chemistry, materials science, life sciences and geological sciences. It will be housed at the Centre of Microscopy.
“I have no doubt that this equipment is going to give our university a great leap forward in research in the fields of electron microscopy and cathodoluminescence,” Prof Ntwaeaborwa said.

Prof Viljoen says the analyser is used to determine nitrogen, carbon/nitrogen, and carbon/hydrogen/nitrogen in organic matrices. The instrument utilises a combustion technique and provides a result within 4,5 minutes for all the elements being determined. In addition to the above, the machine also offers a sulphur add-on module which provides sulphur analysis for any element combination. The CHN 628 S module is specifically designed to determine the sulphur content in a wide variety of organic materials such as coal and fuel oils, as well as some inorganic materials such as soil, cement and limestone.

The necessity of environmental protection has stimulated the development of various methods, allowing the determination of different pollutants in the natural environment, including methods for determining inorganic nitrogen ions, carbon and sulphur. Many of the methods used so far have proven insufficiently sensitive, selective or inaccurate. The availability of the LECO analyser in a research programme on environmental pollution/ food security will facilitate accurate and rapid quantification of these elements. Ions in water, waste water, air, food products and other complex matrix samples have become a major problem and studies are showing that these pollutants are likely to cause severe declines in native plant communities and eventually food security.

“With the addition of the analyser, we will be able to identify these polluted areas, including air, water and land pollution, in an attempt to enhance food security,” Viljoen said. “Excess levels of nitrogen and phosphorous wreaking havoc on human health and food security, will be investigated.”
