Choose excellence and moral uprightness graduates told
Dr Mantwa Lephoto graduated with a PhD in Physics. With her is Dr Kamohelo Tshabalala, her supervisor
It was joy all over at the Qwaqwa Campus of the University of the Free State (UFS) on Thursday 10 May 2018 when over 650 degrees, diplomas, and certificates were conferred on deserving academic achievers. Among the degrees conferred were seven PhDs and seven master’s degrees in the Faculty of Natural and Agricultural Sciences, and one doctorate in English in the Faculty of the Humanities.

Speaking to the proud graduates was the Honourable Acting Judge of the Supreme Court of Appeal, Mr Justice Tati Makgoka, and the Chancellor of the UFS, Dr Khotso Mokhele, who both congratulated the graduates on their success.

Immeasurable joy and pride
“In African culture, a child is a vessel of the community. And today you have not only brought immeasurable joy to your families, but also pride to your communities. You have also opened a window of opportunities and inspiration to the school learners in attendance here today,” said Justice Makgoka, referring to hundreds of invited school learners from as far as Rekgotsofetse Secondary School in Paul Roux.

“You have now assumed the roles of pathfinders among your people. You should therefore continue to share your talents, as well as moral and spiritual gifts, with your communities. Your qualifications today set you on a journey of lifelong learning and scholarship. It is so because your chosen fields of study are dynamic terrains constantly evolving and demanding a lifelong scholarship. We must also pay special tribute to those who contributed towards your success,” he said.

Support system is important
Dr Mokhele also encouraged graduates to thank their support systems that kept them going through the hard times of studying.

 “There are many other people who deserve to be thanked for your success and you must thank them accordingly,” he said, and asked graduates to stand up as a gesture of appreciation for their families and friends who filled up the Rolihlahla Mandela Hall.
He further edged all graduates to ‘choose excellence and moral uprightness’.

“Honest and excellent hard workers in our government are more likely to be constructively dismissed, as they prevent the stealing of state resources. It’s your responsibility to choose the kind of South Africa you want to live in and make it happen,” he said.
 
This year’s graduations also saw the first cohort of Bachelor of Administration students from the Faculty of Economic and Management Sciences graduating.

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.
