Meet the new KovsieCyberSta team
Meet Georgina and Karabo. #KovsieCyberSistas who are doing it for themselves.

After weeks of audition submissions and campaigning for votes the #KovsieCyberSta Search winners have been selected. For the first time since the launch of the UFS Digital Ambassador programme in 2013 the team comprises an all-girl cast.

Second-years Georgina Mhlahlo and Karabo Lekomanyane,who are studying BCom Marketing and BCom Law, respectively, are very excited about the road ahead. 

Reaching the top five last year did not deter Georgina from entering the competition again this year. Being in front of the camera is nothing new to her and she has a YouTube channel on which she shares her own quirky skits and stories. 

“Expect fun, happiness and unpredictability because we love an unpredictable queen,” says Georgina.

Karabo says she plans on bringing the whole kitchen sink to the #KovsieCyberSta role for the next year. 

Georgina and Karabo are names the Kovsie community will get used to hearing and faces they will be seeing over the next year as the pair report on various campus events through short videos which will be published across UFS social media platforms.

A research project into low-energy lighting using phosphor materials for light emitting diodes (LEDs) at the Department of Physics at the University of the Free State (UFS) has received further recognition. 

The South African Research Chairs Initiative (SARChi) has awarded further funding for the Research Chair in Solid State Luminescent and Advanced Materials situated in the department. Prof Hendrik Swart, a Senior Research Professor in the Department of Physics, says this means that the Chair will carry on receiving funds from SARChi for another five years. The Initiative also awarded Prof Swart in 2012 for the research, which resulted in funding for equipment and among others, bursaries.    

Better light emission in LED’s
The research focuses on better light emission of phosphor powers in LEDs. It is also looking into improving LED displays in flat screens. The research into solar cells has shown that phosphors can also increase their efficiency by increasing the range of light frequencies, which convert into electricity. It also entails that glow-in-the-dark coatings absorb light during the day and emit it at night. 

Prof Swart says over the next five years the research will focus on developing and producing devices that emit better light using the substances already developed. “We need to make small devices to see if they are better than those we already have.” In practical terms, it means they want a farmer’s water pump that works with solar energy to work better with less energy input.” 

Device that simulates sunlight
Prof Swart says the renewal of the Chair’s funding means the department can now get equipment to enhance its research   such as a solar simulator. The solar simulator uses white LEDs whose intensity output and wavelengths can be tuned. The output is measured in number of suns. It enables researchers to work in a laboratory with a device that simulates sunlight.     

According to Prof Swart the long-term benefit of the research will result in more environmentally friendly devices which use less energy, are brighter and give a wider viewing field. 

About 10 postdoctoral researchers are working on the studies done by the Chair in collaboration with the Council for Scientific and Industrial Research. 

The Research Chair Initiative aims to improve the research capacity at public universities to produce high-quality postgraduate students, research and innovative outputs. The criterion for evaluating the department’s Chair includes aspects such as how much development has occurred over the past five years. The assessors look at features such as the number of students the research entity has trained and how many publications the research team has produced.
