As the UFS COVID-19 Regulations and Required Vaccination Policy has been lifted with immediate effect – allowing 100% capacity of both students and staff members and a fully operational campus – the
Office for International Affairs welcomes its first physical exchange cohort after two years. The cohort of students hail from the various international partners of the UFS, namely the
University of Bremen in Germany, the Vrije Universiteit Amsterdam, and Sciences PO Bordeaux in France. The students will be hosted in the UFS faculties of the Humanities, Economic and Management Sciences, and Natural and Agricultural Sciences, respectively.
These students have been paired with
Umoja Buddy Programme ambassadors to help ensure their smooth transition and integration into student life at the UFS. Furthermore, the students received an invitation from the President of the
International Student Association (ISA), Courtney Madziwa, to join their association, thus exposing them to students from other countries to learn about the various cultures.
On 18 July, the Office for International Affairs (OIA) arranged a hybrid orientation programme for the exchange students, including those students who have not yet arrived on the Bloemfontein Campus. The students took part in an icebreaker activity, where they had the opportunity to learn from and teach other participants about their home countries. Dr Cornelius Hagenmeier, Director of the OIA, welcomed the exchange students to the Bloemfontein Campus, and expressed excitement to have physical exchanges again. Furthermore, the guest presenters ranged from student leadership, staff members, and service providers.
The presentations were practical, demonstrating, among others, how to create a password on the institutional website – presented by Mr Molemo Mohapi from UFS ICT. The presentation on how to fully utilise Blackboard was facilitated by Ms Vuthihi Mudau from the UFS CTL division. We take the safety of all our students seriously, so Ms Elise Oberholzer from the UFS Protection Services has given the students some tips on how to safeguard themselves.
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.
