UFS celebrates excellence through its research hubs
The university considers its research chairs and the possibility of future chairs as an integral and strategic initiative to increase its national and international standing through excellent academic and research leadership.

The University of the Free State (UFS) is proud of its research leaders. As of 2018 the UFS has 156 NRF-rated researchers and five Sarchi Research Chairs. These chairs are designed to attract and retain excellence in research and innovation at South African public universities.

Getting the better of vector borne and zoonotic viruses

Prof Felicity Burt leads the Vector Borne and Zoonotic Virus Research Group in the Department of Medical Microbiology and Virology at the UFS. She was awarded a Research Chair to, among others, investigate medically significant vector-borne and zoonotic viruses currently circulating - mainly viruses transmitted by mosquitos and ticks, and viruses transmitted from animals to humans. 

“Years ago, no one knew what Ebola was. One outbreak later, backed by many media reports, and it is almost a household name. The same goes for the recent Zika virus outbreak in South America,” she explains the public’s interest and fears. To prevent the spread of vector-borne viruses to new areas, surveillance and awareness is important. Here in Bloemfontein, Prof Burt and her team are establishing surveillance programmes.

Why research on fungal infections?

“Many diseases no longer pose a threat to humans and life expectancy is prolonged. However, this has also caused an increase in various opportunistic infections, and most of all, fungal infections,” says Prof Carlien Pohl-Albertyn, who is heading the Research Chair for Pathogenic Yeasts in the Department of Microbial, Biochemical and Food Biotechnology. And the rise in resistance to antifungal treatments requires research into pathobiology, including new drug and treatment options. 

Activities of the Research Chair in Pathogenic Yeasts builds on existing research strengths and will contribute towards understanding pathobiology of medically significant pathogenic yeasts belonging to the genera Candida and Cryptococcus. 

Understanding higher education for more equality and justice

Prof Melanie Walker, from the Centre for Research on Higher Education and Development (CRHED) does research on higher education, inequalities and social justice, and how, or if, universities foster the human capabilities and aspirations of students. Does higher education make a difference to the lives of students, their families and communities? 

Prof Walker says the Research Chair on Higher Education and Human Development looks at issues of access, participation and transitions into work, as well as gender, race and social class. They use both quantitative and qualitative methods and includes a strand of participatory research projects with students. Ultimately, the research must contribute to debates, policy and practices in higher education, and a scholarly knowledge base.

Reduced emissions make for a better world

Prof Hendrik Swart chairs the research project that looks into low-energy lighting, using phosphor materials for light emitting diodes (LEDs). The Research Chair on Solid State Luminescent and Advanced Materials is situated at the Department of Physics

The research mainly focuses on better light emission of phosphor powers in LEDs.  According to Prof Swart, the long-term benefit of the research will result in more environmentally friendly devices which use less energy, are brighter and give a wider viewing field. Over the next five years they will develop and produce devices that emit better light using the substances already developed. “We need to make small devices to see if they are better than those we already have,” he says. 

Solutions to food insecurity
 

The Department of Plant Sciences’s research project dives into disease resistance and quality in field crops. Heading this Research Chair is Prof Maryke Labuschagne who focuses on crop quality breeding and disease resistance in field crops. 

Her, and her students’ research focuses on the genetic improvement of food security crops in Africa, including such staples as maize and cassava. “These crops are genetically improved for yield, drought tolerance, disease, and insect resistance, as well nutritional value,” she says. Her disease resistance research will focus on crop protein quantity and quality as well as iron, zinc, and beta-carotene biofortification of staple crops such as wheat, maize and cassava. The disease resistance-breeding project will be a continuation of the internationally acclaimed wheat rust research. 

The university considers the research chairs and the possibility of future chairs as an integral and strategic initiative to increase its national and international standing through excellent academic and research leadership.

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
