Prof Paul Oberholster
Prof Paul Oberholster was one of 29 scholars and scientists that were inaugurated as new ASSAf members in earlier this month (19 October 2022).

Prof Paul Oberholster, Director of the Centre for Environmental Management at the University of the Free State (UFS), is the newest academic from the university to be inaugurated as a member of the Academy of Science of South Africa (ASSAf). 

Prof Oberholster was one of 29 scholars and scientists who were inaugurated as new ASSAf members earlier this month (19 October 2022). At the same time, 10 new members of the South African Young Academy of Science (SAYAS) were inaugurated.

As the official Academy of South Africa, ASSAf honours the country’s most outstanding scholars by electing them to membership of the Academy. ASSAf members are drawn from the full spectrum of disciplines. New members are elected each year by the full membership of the Academy in recognition of scholarly achievement. Members are the core asset of the Academy and give of their time and expertise voluntarily in the service of society. The 29 new ASSAf Members bring the total membership of ASSAf to 659.

Science must be in the service

“I feel very honoured to have been selected as a member of the official national academy of science which represents South Africa in the international community of science academies. I am a strong believer that science must be in the service of society. In all my research, I have shown an interest and determination to bring practitioners, students, and scholars together to pursue and foster the betterment of the human condition through its intimate relation to the natural world. The latter is in strong relationship with the vision and mission of the Academy,” says Prof Oberholster about being included in the academy of science.

This honour comes almost a year after Prof Oberholster won the NSTF-Water Research Commission (WRC) Award for his contribution to water resource management in SA over the past five years, with special reference to the field of biological passive wastewater treatment.

According to him, the ASSAf membership means providing evidence-based scientific advice on water resource issues of public interest to government and other stakeholders. He was nominated by Prof Eugene Cloete, the previous Vice-Rector Research and Innovation at Stellenbosch University for his research focus related to water resource management.

Research has direct impact on the most important resources

Prof Corli Witthuhn, Vice Rector: Research and Internationalisation, says the UFS staff and students are proud of the national recognition that Prof Oberholster received for his lifetime achievements in research on water resource management. His research has direct impact on the managing, protection and rehabilitation of one of the country’s most important resources.  

“The demands on our water supplies will increase in the future as a result of climate change globally. We believe his research will become even more important and relevant in the next decade. We are looking forward to his future achievements and will work with him to provide him with the appropriate UFS support.  Congratulations,” says Prof Witthuhn.

State-of-the-art physics equipment and investment in students result in academic success

Nanoscience, which is revealing new properties of very small arrangements of atoms, called nanoparticles, is opening a new world of possibilities. The Department of Physics at the University of the Free State is undertaking fundamental research with potential commercial applications. Its equipment and expertise is giving solid state physics research the edge in South Africa.

The UFS team of researchers and students are passionate about studying planets and atoms, all under one roof. Recently, the department, in collaboration with the South African Agency for Science and Technology Advancement (SAASTA), hosted a nanotechnology facility tour to give the public, learners and the media the opportunity to familiarise themselves with the science of nanotechnology, its origins, potential applications and risks.

Successes of the department
According to Prof Hendrik Swart, Senior Professor in the Department of Physics, the increase in resources since 2008 is playing a big role in the success rate of its research outputs. The Sarchi Chair awarded to Prof Swart in 2012 (bringing with it funding for equipment and bursaries) also contributed to the successes in the department.

The UFS Directorate Research Development also availed funding that was used for bursaries. These bursaries made it possible for the department to appoint 10 post-doctoral fellows, not one of them originally from South Africa.

The investment in people and equipment resulted in researchers and students publishing some 80 articles in 2016. Their work was also cited more than 900 times by other researchers in that year.

Another highlight in terms of the department’s growth in the past 10 years is the new wing of the Physics Building. Physics at the UFS is the only place in sub-Saharan Africa where state-of-the art equipment is found under one roof.

Application of research
The department is a unique research facility with equipment that includes the X-ray Photoelectron Spectrometer (for the study of atoms), the Scanning Auger Microscope, as well as the Ion Time-of-Flight Secondary Ion Mass Spectrometer (revealing the chemical bonds in a sample, and drawing maps of the positions of atoms).

One of the areas on which the department is focusing its research, is phosphors. Researchers are exploring light emitting diodes (LEDs) which use less energy, are brighter and provide a wider viewing field. They are also looking into LED displays (LCDs) which are used in flat screens – the phosphors create the different colours and backlighting.

The research on solar cells reveals that phosphors can increase their efficiency by increasing the range of light frequencies which can be converted into electricity. Glow-in-the-dark coatings absorb light in the day and emit it later so cells can charge at night. As glow-in-the-dark phosphors become cheaper and more effective, they can be used as a lighting substitute on the walls of houses, street numbers and stop signs.
