Abe Bailey Bursary victor
“I believe in self learning,” says 2018 UFS Abe Bailey victor, Nkahiseng Ralepeli.
The Abe Bailey Trust is a leadership-development opportunity that targets university students or junior lecturers who are academically strong and have shown exceptional qualities of leadership and service. Recipients of the bursary are required to have a good record of accomplishments, not only on campus but also in a broader social context, where they function as an integral piece of a select and highly-skilled group of individuals.

Ralepeli, the over-achiever

Final-year Law student, Nkahiseng Ralepeli, embodies this exact description and exemplifies the essence of distinction and merit when it comes to who he is. Ralepeli  who has represented the university at various international debate platforms, an alumni of the F1 programme to Thailand and other leadership programmes such, recently, International Youth Leadership Conference (IYLC) programme in Prague, will represent the University of the Free State (UFS) during the Abe Bailey Travel Bursary tour in the UK in December 2018. He, along with 16 other candidates from other South African tertiary institutions, will participate in the tour for its full duration and will take part in the exciting developmental programme that is planned.

With an intense but fruitful leadership-training schedule, he said he was looking forward to meeting the British members of parliament as well as other persons of stature in the British government.

Travelling: A catalyst for critical thinking

Ralepeli, who was also 3rd overall Kovsie Dux student, underlined that he truly enjoys travelling. He has subsequently mastered the art of constantly positioning himself among the best academically and socially, and this has aided his mission to trot the globe extensively, which he has been doing since his junior years.

A man of value

“I have a small yet select and impactful network of people in my life who play an influential role in reminding me during times of triumph that, while it is important to celebrate, each win is just a step towards the ultimate goal of success,” said Ralepeli. 

He emphasised the importance of the roles played by those close to him, describing them as “my double-edged sword who played a crucial role in carving out the inner Nkahiseng, who, hopefully, will do great things”. The Kovsie Dux believes that those you surround yourself with, channel the kind of energy that will either make or break you.

UFS involved in project to light up the townships
2006-06-06

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.
