During October, the national focus is on mental health. Mental Health Awareness Month also coincides with a time when our students prepare for the end of the year exams, making it a particularly valuable time for us to think about how we can continuously assist them during their time at university. The value of peer support and genuine care can never be overstressed; that is why I want to encourage our students to reach out to their support networks such as our Department of Student Counselling and Development, as we move towards the end of the year.
Mental health is an equally important matter for our staff. During this month, I want to encourage our staff to also take cognisance of their own well-being. There is a lot of wisdom in the old adage: Healthy body, healthy mind. Many of the initiatives of our Division of Organisational Development and Employee Wellness are focused on the value of physical activity and the negative impact that inactivity can have on one’s productivity and mental health. They also present regular lunch-hour sessions for our staff, where experts share information and practical tips for mental wellness. I want to encourage our staff to attend these sessions and to make use of the services the university has to offer in this regard. It is important to note that suffering from mental and anxiety disorders is not weaknesses and it is not always indicative of a deeper psychological issue; it is an illness and hence can be treated.
On 20 September 2019, a 21-member team was sent off on their run of 1 075 km to Stellenbosch to raise awareness for mental health. The run was organised by the Division of Organisational Development and Employee Wellness and the Faculty of Health Sciences. The team ran in relay format throughout the night and handed the baton of hope to Stellenbosch University on 25 September 2019. I admire and thank them not only for their commitment and stamina, but also for addressing this crucial matter in the public domain and for raising awareness in the many towns and communities along the way.

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.
