The University of the Free State (UFS) recently hosted its annual Research Awards function at the Wynand Mouton Theatre on the Bloemfontein campus. Present at this event on 26 September 2023 were Prof Francis Petersen, the Vice-Chancellor and Principal of UFS, Prof Crain Soudien, a globally renowned academic and the President of the Cornerstone Institute, and members of the UFS academic community, among others.

The awards ceremony

Prof Petersen stated, ‘’The purpose of the event is to recognise scholars at the University of the Free State who are conducting outstanding research in their respective fields of expertise.’’ Certificates were presented to researchers in various categories, including National Research Foundation (NRF) Rated Scholars from categories P to A. Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation at the UFS, highlighted that there are precisely 217 NRF-rated scholars within the institution. However, some of these scholars had not been acknowledged internally. Hence, the ceremony aimed to celebrate these scholars.

Furthermore, UFS staff members were acknowledged for their research at both national and international levels. Prof Abdon Atangana, named as one of five recipients of the inaugural UNESCO-Al Fozan International Prize for the Promotion of Young Scientists in Science, Technology, Engineering and Mathematics (STEM), was among these individuals. Future professors of the institution who are part of the Professoriate Programme were also recognised for their outstanding performance in transforming the programme.

The highly anticipated category of the evening was the UFS Book Prize for distinguished scholarship. Prof Reddy explained, ‘’the purpose of the award is to recognise outstanding publications produced by any permanent member of the UFS staff, which are research-based and published in a book. Prof Soudien, who was the guest speaker for the evening and one of the reviewers of the books nominated in this category, indicated that he found the books ‘’illuminating and in many ways challenging of positions I hold and positions that I think that we all ought to be reflecting on in terms of where our world is going’’.

From the four nominees vying for this award, Prof Helene Strauss was announced as the winner of the 2022 UFS Book Prize for her book entitled, ‘Wayward Feeling: Audio-Visual Culture and Aesthetic Activism in Post-Rainbow South Africa’. Strauss expressed her appreciation, saying, ‘’It is a great honour to be awarded the UFS Book Prize given the high calibre of this year's nominees. It is a lovely morale boost at this time of the year when our motivation can start to flag under the weight of the workload. It inspires me to continue to try to live up to the many examples of outstanding research produced on this campus.’’ The prize includes a certificate of honour as well as a monetary award.

The significance of the awards ceremony

While the award ceremony aims to recognise and celebrate research outputs by the UFS staff, Prof Petersen emphasises that it is also an acknowledgement of the researchers’ impact. Through their contributions, they elevate the research profile of the institution, thereby bringing the vision of becoming a research-led university, as outlined in Vision 130, closer to reality.

UFS involved in project to light up the townships

The parties involved with the project are from the left: Prof Hendrik Swart (Departmental Chairperson of the UFS Department of Physics), Dr Thembela Hillie (CSIR), Prof Neerich Revaprasadu (Department of Chemistry at the University of Zululand) and Dr Wynand Steyn (CSIR).

UFS involved in project that could light up the townships

The University of the Free State’s (UFS) Department of Physics is involved with a project that could make life easier in the townships through the use of artificial light.

“The project is based on the use of sunlight to activate nano material in for example cement and paint during the day. At night the cement or paint can then radiate light,” said Prof Hendrik Swart, Departmental Chairperson of the UFS Department of Physics.

According to Prof Swart an amount of R3,9 million has been made available by the Council for Scientific and Industrial Research (CSIR) for the further development of the project.

Prof Swart visited the University of Florida in America in 1995 for a year where he researched luminescent phosphor material that is suitable for flat panel television screens. The red, green and blue spots on the television screens originate from these kinds of phosphor materials. “At that stage plasma television screens were only a dream. Today it is sold everywhere,” said Prof Swart.

“Upon my return I started a research group at the UFS which investigated the degrading of phosphor material. We also started to concentrate on the effectiveness of nano phosphors. In the mean time our cooperation with the Americans was strengthened with follow-up visits to America of my colleagues, Prof Koos Terblans and Mr Martin Ntwaeaborwa,” said Prof Swart.

“Nano phosphors are basically luminescent powders that consist of particles that are 1 millionth of a millimetre. These particles can provide light as soon as they are illuminated with, for instance, sunlight. The amount of time these particles can provide light, is determined by the impurities in the material,” said Prof Swart.

According to Prof Swart nano particles are developed and linked to infrastructure materials in order for these materials to be excited during the day by sunlight and then it emits light during night time.

“The nano material is of such a nature that it can be mixed with materials, such as paint or cement. The yellow lines of roads can for example emit light in a natural way during night time,” said Prof Swart.

About a year ago Prof Swart and Dr Thembela Hillie, a former Ph D-student of the UFS Department of Physics, had discussions with Prof Neerich Revaprasadu from the University of Zululand and the CSIR about the possibility of mixing these nano phosphor particles with other materials that can be used as light sources in the building of roads and houses.

“Prof Revaprasadu is also actively involved in the research of nano materials. Our efforts resulted in the CSIR approving the further extension of the project,” said Prof Swart.

“The UFS and the University of Zululand are currently busy investigating ways to extend the light emitting time,” said Prof Swart.

“There are eight M Sc and Ph D-students from the UFS and about five students from the University of Zululand working on this research project. The Department of Physics at the Qwaqwa Campus of the UFS, with Francis Dejene as subject head, is also involved with the project,” said Prof Swart.

According to Prof Swart the further applications of nano materials are unlimited. “Children whose parents cannot afford electricity can for instance leave any object such as a lamp, that is covered with these phosphor particles, in the sun during the day and use it at night as a light for study purposes,” said Prof Swart.

According to Prof Swart the further extension of the project will take about two years. “During this time we want to determine how the effectiveness of the phosphors can be increased. Discussions with the government and other role players for the possible implementation of the project are also part of our planning,” said Prof Swart.
