After two years of lockdown, online meetings, and limited contact with colleagues, academy at the University of the Free State (UFS) is gradually returning to normal. This month (February 2022), staff, students, and members of related industries will convene on three different occasions to learn about cutting-edge scholarship, to reconnect with each other, and to discuss issues impacting society in the fields of theology, the humanities, and agriculture.
Seminar on ‘The Limits of Decolonisation’ with Prof RW Johnson
Date: 24 February 2022
Time: 09:00-16:00 SAST
Venue/Platform: Equitas Auditorium, UFS Bloemfontein Campus, and Microsoft Teams
Decolonisation has been a heated point of discussion for some time now, but have you ever wondered if there could be limitations hindering the decolonisation project? The Departments of Political Studies and Governance and Philosophy and Classics at the UFS will host an array of academics and experts for a hybrid seminar on the topic The Limits of Decolonisation.
If decolonisation is an important issue for you or if you are interested in the topic and its relevance and influence in the world and academia, you should join or attend the seminar – either online via Microsoft Teams or in person in the Equitas Auditorium – on 24 February 2022 from 09:00.
The keynote speaker is political scientist
Prof RW Johnson from the University of Oxford. Prof Johnson is an emeritus fellow at Magdalen College and is the author of several acclaimed political books. The other speakers are all from the Departments of Political Studies and Governance, and Philosophy and Classics. Terrence Corrigan from the
South African Institute of Race Relations will speak on The relationship between critical race theory and decolonisation.

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.
