Muhammad Cassim, a second-year student in the Department of Engineering Sciences in the Faculty of Natural and Agricultural Sciences at the University of the Free State, will participate in the winter university project in Pskov, Russia, from 25 November to 9 December 2024.
The winter school aims to strengthen relationships among young engineers and deepen international interaction via skills improvement, joint projects, and social cohesion. The programme boasts a densely packed education block, project block, and cultural block.
Cassim is part of the UFS Grid Related Research Group and actively participates in research centred on complexity science. He intends to complete his BSc Physics degree with Engineering subjects and progress towards postgraduate studies in the UFS Department of Physics.
He is currently working on verifying experimental developments in the field of synchronisation in complex networks. While he has already completed this high-performance computing training in his first year under the leadership of Albert van Eck (Director, UFS E-research), he is looking forward to the masterclasses in holographic modelling, deep learning, direct laser deposition, and database. Closely resembling his current research, he will have the opportunity to gain more experience in the use of set theory and graph theory in solving digital information processing problems.
For more information about international scholarships for study abroad opportunities, contact Mbali Moiketsi in the Office for International Affairs.
Cassim’s student profile is the culmination of the department’s strategy to produce young applied scientists who are subjected to the culture of research during their undergraduate study and could articulate with ease to other departments for postgraduate studies. The department aims to align with the UFS’ Vision 130 by producing competitive students who can operate in the postgraduate paradigm with the digital themes of veterinary science and ecological engineering science.

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.
