Lefébre Rademan
Lefébre Rademan, new captain of the Free State Crinums netball team, could be one of the star players in the Premier League. She is a fifth-year Education student.

The Free State Crinums netball team, a de facto Kovsie team with all 15 squad members enrolled for courses at the University of the Free State (UFS), will draw inspiration from their success in last year’s Varsity netball tournament. The Kovsies won the student competition for a record third time. 

During the weekend of 10 May 2019, the Crinums will play their first match in the 2019 Premier League. They lost a couple of key players in captain Alicia Puren, Protea Khanyisa Chawane, (both playing for the national invitational team in the league), Khomotso Mamburu (moved to Cape Town), and Meagan Roux (injured). They do, however, still have the services of players such as Tanya von Berg (playing in her sixth Premier League, one of only a handful of players to do so), Lefébre Rademan, Sikholiwe Mdletshe, Ané Retief, Gertriana Retief, and Rieze Straeuli. Rademan is the new captain and was one of the standout players in last year’s Varsity netball, earning three Player of the Match awards, including the Player of the Final. 

The team will again be coached by Burta de Kock, who is also the head coach of the Kovsies. Under her leadership, the Crinums won the Premier League for the first three years (2014 to 2016). Last year, the Crinums ended fourth. De Kock will be assisted by Martha Mosoahle-Samm. She is a former Protea assistant coach who also captained South Africa and played for the UFS between 1997 and 1999.

There are four first-year students in the squad of 15 players: Oageng Khasake (wing attack), Ancia Pienaar (goalkeeper), Rolene Streutker (goal shooter), Boitumelo Mahloko (goal defence). Pienaar and Mahloko both represented South Africa at junior level in 2018.

■ Crinums squad: Ané Retief, Gertriana Retief, Jana Scholtz, Lefébre Rademan, Sikholiwe Mdletshe, Tanya von Berg, Rieze Straeuli, Claudia van den Berg, Zandré Smit, Oageng Khasake, Bianca de Wee, Ancia Pienaar, Rolene Streutker, Chanel Vrey, Boitumelo Mahloko.

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.
