Residence members who led the project, included:
Bohlokwa Rantja, the Residence Prime, and Transformation Committee members Nsuku Mutemela, Ofentse Motlakeng, Phindile Tjale, Madinku Mabala, Mmapopi Motshoso, Karabo Shuping, and Tagane Sekete.
The University of the Free State (UFS) Council approved and adopted Lehakwe House as the new name for the
NJ van der Merwe residence on the Bloemfontein Campus. The approval on 26 November 2020 followed a lengthy process of deliberation, consultation, and public engagement that has taken place since November 2019 and is aligned with the UFS Policy on Naming and Renaming. The name-change process was initiated by the Prime and Transformation Committee of the residence, guided by the
Unit for Institutional Change and Social Justice and supported by a multi-stakeholder committee representative of the residence, the Housing and Residence Affairs Office, the Department of Student Affairs, the Student Representative Council, and alumni.
Lehakwe – a precious gem
Following a lengthy evaluation process of the names submitted through a public voting and recommendation platform in July 2020, ‘Lehakwe’ – a Sesotho word referring to a ‘precious gem’ – emerged as the front runner. As many current and past members of the residence attest, this womxn’s residence has come to occupy a significant space within the hearts and minds of UFS students and the UFS community, given that its spirit has always been closely aligned with the constitutional values of dignity, equality, and freedom and with the human values of ubuntu. In this vein, the new name of ‘Lehakwe’ presents a consolidation of constitutional and university values into the day-to-day thinking, learning, living, and legacy spaces of students, as well as everyone who interacts and engages with the UFS.

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.
