Dr Mirriam Moleko, a lecturer in the Department of Mathematics, Natural Sciences, and Technology Education in the UFS Faculty of Education, participated in the National Research Foundation’s Black Academics Advancement Programme fellowship and got the opportunity to visit universities and schools in the USA for three weeks.

After completing the National Research Foundation’s Black Academics Advancement Programme (BAAP) fellowship, a lecturer from the University of the Free State (UFS) now wants to train more teachers on issues of access and inclusivity in different mathematics settings. She also wants to establish a centre for access and inclusivity to promote quality teaching that caters to a diverse learner population.

Dr Mirriam Moleko, a lecturer in the UFS’s Department of Mathematics, Natural Sciences, and Technology Education in the Faculty of Education, participated in the BAAP fellowship, an initiative of the National Research Foundation (NRF) and the FirstRand Foundation (FRF), from 2021 to 2022. She also got the opportunity to visit universities and schools in the USA for three weeks.

Supporting emerging academics

Dr Moleko says the BAAP is a prestigious NRF programme which supports well-structured research projects with achievable aims, sound methodologies, and demonstrated prudent use of funds. The programme supports emerging academics to ensure that they develop strong research skills, collaborate with prolific scholars in their fields, visit other universities abroad, give public lectures, and attend international conferences to establish an international footprint.

“The programme allows the candidates awarded the grant to focus on research for two years” she says. “I managed to run my teacher community research project successfully during this period. My goal as an academic and a researcher is to produce work that teachers can relate to and be able to apply in their profession. I have always aspired to empower teachers to be knowledgeable and resourceful”.

“Furthermore, my goal is to strive to partake in critical conversations that are taking place within the mathematics education field, and to contribute my skills and knowledge in addressing the existing challenges, thus being part of the solution. I believe the skills that I have gained on how to conduct quality research will assist me in achieving my goals,” she added.

Benefit from funding

During the period of her fellowship she learned about forming partnerships and collaborating with other scholars in her field, which she believes is an important skill to possess as a developing scholar.

Dr Moleko says the programme played a pivotal role in the attainment of numerous significant accomplishments in her professional career thus far. She also benefitted in terms of funding, which helped her undertake autonomous research and advanced training in her area of expertise, as well as facilitated engagement in collaborative research ventures with esteemed professionals and researchers, both domestically and abroad.

“The research leave that I got enabled me to successfully conceptualise, strategise, and implement a research endeavour that yielded a more profound comprehension of the research gap that I had identified within the teacher community, thus culminating in multiple publications in esteemed periodicals.

“The NRF-BAAP funding also enabled me to undertake training, thereby refining my skill set and augmenting my comprehension of intricate principles. The experience proved to be a crucial factor in my vocational growth and bolstered my aptitude for scholarly inquiry. It also afforded me the chance to engage in mentoring endeavours for fledgling researchers.”

Transformation of the Professoriate Mentoring Programme

Dr Moleko, who is part of the UFS Transformation of the Professoriate Mentoring Programme, says this programme is an excellent initiative which is aimed at preparing young academics for future promotions and offering them skills to be competitive. The programme’s goals include building strong academics who will follow in the footsteps of the university’s current leaders.

She says the programme is critical in supporting young academics by connecting them with seasoned mentors and scholars from various fields of study. It is essential for young academics in terms of maximising their learning, expanding their network, and gaining opportunities to help facilitate their growth.

“I see the programme as a catalyst for change necessary for the university to realise the desired results,” Dr Moleko says.

During her visit to the USA she spent two weeks at Boston College and the University of Rhode Island, and also visited the Center for Applied and Specialised Technology, the Paul V. Sherlock Center on Disabilities (Sherlock Center), and the TechACCESS Center.

“The purpose of my visit was to establish networks and collaborate with prolific scholars outside South Africa on research engagements. Furthermore, the visit was intended for me to meet with my international mentors in person regarding research engagements.

“During my research visit, Prof Elizabeth Dalton from Rhode Island University and a UDL specialist, and I focused on several academic conversations and demonstrations of Universal Design for Learning (UDL) strategies and approaches, as well as the sharing of many online resources available to support the implementation of UDL in inclusive settings.”

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
