Dr Ismari van der Merwe was instrumental in establishing the new Department of Sustainable Food Systems and Development.

Dr Ismari van der Merwe believes that by forging strong relationships, women can affect virtually every aspect of their students' lives, teaching them vital life lessons that will help them succeed beyond term papers and standardised tests. 

She states that it is not always easy to change a student's life, so it takes a great teacher to do so. “You, as a teacher, have a very significant, lifelong impact on all your students. This impact involves not only the teaching of particular academic skills, but as importantly, the fostering of student self-esteem.”

“Reinforcing self-esteem in the classroom is associated with increased motivation and learning,” she says.

Dr Van der Merwe is Lecturer and Programme Director in the Department of Sustainable Food Systems and Development at the University of the Free State (UFS).

On 11 February – International Day of Women and Girls in Science – the UFS is celebrating her not only for the impact she has on her students, but also for being instrumental in establishing the new Department of Sustainable Food Systems and Development, putting the UFS on the international forefront.

A sustainable food system

“We want our students to be part of a sustainable food system that provides healthy food that meets food needs, while maintaining healthy ecosystems that can also provide food for generations to come, with minimal negative impact to the environment,” she says. 

“The right to food is a fundamental human right.”

Dr Van der Merwe believes that a healthy personal food system and how it is managed is now more critical than ever before. 

Her current work involves managing the five main food-related values of taste, health, cost, time, and social relationships, as well as other less prominent values of symbolism, ethics, variety, safety, waste, and quality within these personal food systems. She feels the prominence of these values varies among us as well as across our eating situations. “More research on this will be fascinating,” says Dr Van der Merwe. 

A male-dominated field

On the role of women in science, Dr Van der Merwe says it is often considered a male-dominated field. “According to United Nations data, less than 30% of scientific researchers worldwide are women,” she states.

Telling her story about becoming a scientist, she says that science chose her. “Many scientists have reported that their interest and curiosity in science or the natural world started in early childhood.”

“I started as a teacher and ended up working for the Agricultural Research Council, where I was responsible for a research programme on dry beans and started a small-scale research factory.”

“Later when we moved to Bloemfontein, I joined the UFS. Here I am privileged to be able to do research and teach. Science chose me as part of my life journey, and I never looked back.”

Nanoscience, which is revealing new properties of very small arrangements of atoms, called nanoparticles, is opening a new world of possibilities. The Department of Physics at the University of the Free State is undertaking fundamental research with potential commercial applications. Its equipment and expertise is giving solid state physics research the edge in South Africa.

The UFS team of researchers and students are passionate about studying planets and atoms, all under one roof. Recently, the department, in collaboration with the South African Agency for Science and Technology Advancement (SAASTA), hosted a nanotechnology facility tour to give the public, learners and the media the opportunity to familiarise themselves with the science of nanotechnology, its origins, potential applications and risks.

Successes of the department
According to Prof Hendrik Swart, Senior Professor in the Department of Physics, the increase in resources since 2008 is playing a big role in the success rate of its research outputs. The Sarchi Chair awarded to Prof Swart in 2012 (bringing with it funding for equipment and bursaries) also contributed to the successes in the department.

The UFS Directorate Research Development also availed funding that was used for bursaries. These bursaries made it possible for the department to appoint 10 post-doctoral fellows, not one of them originally from South Africa.

The investment in people and equipment resulted in researchers and students publishing some 80 articles in 2016. Their work was also cited more than 900 times by other researchers in that year.

Another highlight in terms of the department’s growth in the past 10 years is the new wing of the Physics Building. Physics at the UFS is the only place in sub-Saharan Africa where state-of-the art equipment is found under one roof.

Application of research
The department is a unique research facility with equipment that includes the X-ray Photoelectron Spectrometer (for the study of atoms), the Scanning Auger Microscope, as well as the Ion Time-of-Flight Secondary Ion Mass Spectrometer (revealing the chemical bonds in a sample, and drawing maps of the positions of atoms).

One of the areas on which the department is focusing its research, is phosphors. Researchers are exploring light emitting diodes (LEDs) which use less energy, are brighter and provide a wider viewing field. They are also looking into LED displays (LCDs) which are used in flat screens – the phosphors create the different colours and backlighting.

The research on solar cells reveals that phosphors can increase their efficiency by increasing the range of light frequencies which can be converted into electricity. Glow-in-the-dark coatings absorb light in the day and emit it later so cells can charge at night. As glow-in-the-dark phosphors become cheaper and more effective, they can be used as a lighting substitute on the walls of houses, street numbers and stop signs.
