Proteas next goal for Khanyisa
Khanyisa Chawane is going places with her netball career. She finds inspiration from God and the people she surrounds herself with.
Netballer Khanyisa Chawane singles out friends, teammates and her Kovsie coach as the ones who have had the biggest hand in promoting her career.

“Coach Burta de Kock has had an impact on me as a player and person. She took me in, groomed me and taught me the ins and outs of becoming the player I am today,” Chawane says.

They picked me up when I was down

“Maryka Holtzhausen (Free State teammate) has played quite a role in my career as a teammate and mentor. Tiisetso Mashele is a very good friend who has always been there to lend a helping hand during the tough times and remind me where my strength comes from. Then there’s Khomotso Mamburu and Sikholiwe Mdletshe who’ve become more than teammates. They understand me and always manage to pick me up when I’m down and there’s never a dull moment when they are around.”

At the age of 22 Chawane is making huge strides on the netball court.

Crowned player of the tournament

Hardly a month after she was named Player of the Tournament of the Brutal Fruit Netball Premier League, her performances at the National Championship mid-July earned her the Player of the Tournament once more. She is the first player to receive these accolades at both these tournaments in the same year. 

“The people I surround myself with keep me motivated in every aspect of my life. The grace of God upon my life is what inspires me to keep going. 

“I would love to represent the Proteas at the Quad Series and Diamond Challenge later this year and also to win the Varsity Netball Series,” Chawane says about future goals.

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.
