Two postgraduate students from the University of the Free State (UFS) were honoured at this year’s Women in Science Awards (SAWiSA) hosted by the Department of Science and Innovation (DSI).

Thandokuhle Gama, a Master of Medical Science student with specialisation in Pharmacology, and Anele Mthembu, who is working on her master’s degree in Disaster Management in the Disaster Management Training and Education Centre for Africa (DIMTEC), are both recipients of the DSI-Esther Mahlangu Master's Fellowships.

This fellowship is awarded to women scientists and researchers who are pursuing their master’s or doctoral studies and already hold scholarships from the National Research Foundation or other DSI agencies. The fellowships for Gama and Mthembu are worth R75 000 each and can be used towards their tuition fees or to enhance academic programmes by covering the costs of attending conferences or specialised research materials and equipment required to complete their degrees.

Honouring Dr Esther Mahlangu

The prestigious 2024 SAWiSA, which honour the exceptional contributions of women to science, technology, engineering, mathematics and innovation (STEMI) in South Africa, took place on 15 August 2024 in Mbombela. The theme was “Transition towards an Innovation Economy: The Role of Women Leaders in STEM”.

This year, the awards honoured world-renowned artist, Dr Esther Mahlangu, by renaming this year's master's and doctoral fellowships the DSI-Esther Mahlangu Fellowships.

“I feel honoured and grateful for the recognition, although it's been difficult to process what it actually means. It has been an overwhelming experience. It came as a surprise, because when I applied, I was not sure what to expect because these are national awards with many other applicants,” says Gama.

She was nominated by Innocensia Mangoato, lecturer in the UFS Department of Pharmacology and a previous winner at the awards. Gama is doing research on medicinal plants that are used in traditional medicine to treat diabetes.

“Winning this award means that my work thus far is being recognised. It is all through God’s grace. I'm also grateful to everyone who has contributed towards my journey: my family, teachers, mentors and sponsors, and everyone else. It will allow me to continue to advance research in the field of diabetes treatment using traditional medicines or medicinal plants.”

Bettering lives

Mthembu, who was nominated by her mentor, Dr Tlou Daisy Raphela-Masuku, a lecturer at DIMTEC, says it is a fantastic feeling winning this award. “Before the awards, Dr Raphela-Masuku and I dreamt I could win the SAWiSA. But before then, I was surprised and grateful for being acknowledged by DSI as a finalist; I focused on being a DSI finalist, and that winning would be a bonus,” she says.

She continues: “It means a lot to me to win the DSI Master’s Fellowship, as it is a testimony of God’s grace in my life. It is the destiny for helpers God has placed in my life, including my mentor, supervisor, and the DIMTEC postgraduate school. We all won!”

Mthembu is working her master’s thesis on the integration of risk-informed development (RID) and nature-based solutions (NbS) into sustainable human settlements in eThekwini Municipality, KwaZulu-Natal.

“The overarching aim is to evaluate the integration of both these concepts into human settlements’ strategic planning to offer eThekwini Municipality innovative and ecosystem-based approaches to achieving sustainable and resilient human settlements and achieving Sustainable Development Goal (SDG) 11 on building resilient cities.

“I hope to publish my findings and contextualise the enabling environments for RID (EE4RID) Framework in eThekwini Municipality so they can make risk-informed decisions on development and human settlements to achieve SDG 11,” explains Mthembu.

Gama says the aim with her research is to determine if these medicinal plants can treat diabetes by stimulating stem cells to differentiate and become insulin-producing cells. She hopes that through this research diabetes treatment can advance from a level where it is being continuously managed, to a level where we can cure the disease.

UFS researcher engineers metal surfaces

It is well known that the surface of a component is much more vulnerable to damage than the interior, and that surface-originated degradation such as wear, corrosion, and fracture will eventually destroy the component.

“Engineering the surface, based on scientific knowledge, is essential to control these damaging processes. It also creates electronic and geometric structures on the surface which opens up a world of new devices, especially considering the properties on the nano-length scale,” said Prof Wiets Roos from the Department of Physics at the University of the Free State (UFS).

At elevated temperatures, atoms are more mobile and can migrate to grain boundaries and surfaces, which have a major influence on material properties. The redistribution of solute atoms between the surface and the bulk of the material is known as segregation. Knowing the behaviour of segregation at the surface/environment interface can be very useful in the development of new materials. As an example materials can be improved higher efficiency and lower fuel consumption, thus reducing environmental pollution.

The main aims of Prof Roos’s research are to understand surface segregation, use it as a tool, and contribute to the various surface engineering fields.

The surface characterisation laboratories at the UFS are well equipped to do high temperature segregation measurements, and have already proven a success, not only in the ability to prepare the specimens for characterisation, but also in developing models and procedures to quantify the segregation parameters.

The most recent results have demonstrated the importance of taking evaporation into account during quantification.” This has laid the foundation for future studies by installing the necessary hardware in a surface characterisation spectrometer, establishing experimental protocols, and improving an existing model (developed in this laboratory) for simulating segregation profiles,” said Prof Roos.

Segregation parameters allow the researcher to predict and utilise the surface concentration behaviour as a function of temperature and time. “This not only contributes to fields involving corrosion, oxidation, sintering, wear, chemical poisoning, powder metallurgy, and lubrication but adds to the development of self-healing devices,” said Prof Roos.
