Keafon Jumbam is gearing herself for the institutional Three Minute Thesis competition.
Keafon Jumbam is a PhD candidate whose research on food and foxes has won her the first prize of R8 000 in the recent Faculty of Natural and Agricultural Sciences’ Postgraduate Flash Fact Competition. Her brief in the competition was to
summarise her research in three minutes, using only one static slide.“The competition started at departmental level on both campuses. The idea was that the best student in each department is then selected to go for the faculty-level competition on the Bloemfontein Campus. Summarising the entire research into three minutes is no easy feat, but a great way to gauge how well one has mastered your work,” she said.
Far-reaching research
“Thought-provoking presentations on research, ranging from technology to track academic progress, traditional medicine as alternatives to expensive prescriptions, and suggesting insects as food alternatives to curb hunger in this era of severe droughts and food shortages. The competition was tough, but it highlighted the level of research competitiveness on the Qwaqwa Campus. I hope that more students will join in such opportunities to build themselves up and to showcase our research output as Qwaqwa students,” added Jumbam from the
Department of Zoology and Entomology.
Institutional finals
Her next challenge is the institutional competition to be held on 23 August 2019, which could qualify her for the national competition.
UFS Physics Research Chair receives more funding

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.
