Lefébre Rademan, the country’s top student netball player in 2019, has been snatched up by English netball club London Pulse to play in England in 2021.

 

Attempting to become an even better netballer, former Kovsies netball captain Lefébre Rademan decided to jet off to England to play in their league.

Rademan was contracted by London Pulse to compete in the European Superleague in 2021. She will be the fourth Kovsie after Maryka Holtzhausen (2015 and 2018-2019), Karla Pretorius (2016), and Khanyisa Chawane (2020) to play in the league.

Rademan said it was an easy decision, even though it will be far and a long time away from home. The league runs from February to July, with a pre-season in December. She will continue with her master’s degree at the University of the Free State next year.

“I am not going to play netball forever and such an opportunity doesn’t come often. Having competed against England, New Zealand, and Jamaica earlier in the year, I realised they play at a much higher level and if I want to improve and become the best, I would also need to move to a next level.”

“As a goal attack, having Protea teammate Sigi Burger (goal shooter) at the same club, will be an advantage for both of us and for the Proteas as a combination.”

Rademan has had a great past two years, making her Protea debut (12 tests in total) and receiving a number of accolades, such as the Varsity Netball Player of the Tournament in 2019.

In the Telkom Netball League in October, captaining the Free State Crinums, she was named Shooter of the Tournament. She was Player of the Match twice. Her goal average of 88,1% was the highest in the competition.

“Last year was such a good year for me personally, but that remains in the past. You can’t become complacent. I want to keep working hard and become a much better player,” Rademan said.

UFS researcher engineers metal surfaces
2015-03-03

Shaun Cronjé, a PhD student, in a surface characterisation laboratory at the UFS.

It is well known that the surface of a component is much more vulnerable to damage than the interior, and that surface-originated degradation such as wear, corrosion, and fracture will eventually destroy the component.

“Engineering the surface, based on scientific knowledge, is essential to control these damaging processes. It also creates electronic and geometric structures on the surface which opens up a world of new devices, especially considering the properties on the nano-length scale,” said Prof Wiets Roos from the Department of Physics at the University of the Free State (UFS).

At elevated temperatures, atoms are more mobile and can migrate to grain boundaries and surfaces, which have a major influence on material properties. The redistribution of solute atoms between the surface and the bulk of the material is known as segregation. Knowing the behaviour of segregation at the surface/environment interface can be very useful in the development of new materials. As an example materials can be improved higher efficiency and lower fuel consumption, thus reducing environmental pollution.

The main aims of Prof Roos’s research are to understand surface segregation, use it as a tool, and contribute to the various surface engineering fields.

The surface characterisation laboratories at the UFS are well equipped to do high temperature segregation measurements, and have already proven a success, not only in the ability to prepare the specimens for characterisation, but also in developing models and procedures to quantify the segregation parameters.

The most recent results have demonstrated the importance of taking evaporation into account during quantification.” This has laid the foundation for future studies by installing the necessary hardware in a surface characterisation spectrometer, establishing experimental protocols, and improving an existing model (developed in this laboratory) for simulating segregation profiles,” said Prof Roos.

Segregation parameters allow the researcher to predict and utilise the surface concentration behaviour as a function of temperature and time. “This not only contributes to fields involving corrosion, oxidation, sintering, wear, chemical poisoning, powder metallurgy, and lubrication but adds to the development of self-healing devices,” said Prof Roos.
