The Faculty of Economics and Management Sciences (EMS) at the University of the Free State (UFS), in collaboration with Allan Gray, proudly hosted the annual Allan Gray Achievement Awards on 11 October 2023. This special event, held at the Awela Restaurant on the UFS’s Bloemfontein campus, was designed to celebrate the academic achievements of top-performing students within the faculty, recognising their excellence based on their year of study. 

The award ceremony was attended by distinguished members of the EMS Faculty, the Commercio Students Association, and a delegation from Allan Gray, including Katherine Swartland, Managing Business Analyst, Yonela Makalima, Business Analyst, and Steven Motloung, Manager. The evening's guest speaker was Liz Letsoalo, a renowned entrepreneur and TEDx speaker. Notably, this ceremony marked a significant return to in-person events since the outbreak of the COVID-19 pandemic, and Katherine Swartland, who served as the programme director, described this resurgence as truly exciting. 

The award winners

The Allan Gray Achievement Awards highlighted outstanding students from various year levels. In the second-year category, Modisaotsile Seekoei received a prestigious award of R5 000 along with a Thule backpack, while Melissa Mlotshwa was granted a prize of R3 000. Among the third-year students, Anthea Ralane was recognised with an award of R8 000 and a Thule backpack, and Modiehi Mpakathe was the recipient of a R5 000 prize. In the fourth-year category, Kelebogile Motlhanke earned a remarkable R12 000 reward and a Thule backpack, and Rykers Lues was presented with a prize worth R8 000. 

Although not all students attending the ceremony received awards, Prof Brownhilder Neneh, the Vice Dean for Research Engagement and Internationalisation, aptly reminded the audience, ’It is important to recognise that each of you here is already a winner, as your presence signifies that you are among the top achievers in your field. You have demonstrated that with passion, perseverance, and a commitment to your goals, there are no limits to what you can accomplish.’’ 

A longstanding relationship

The Allan Gray Achievement Awards holds deep roots in a special relationship between the UFS and Allan Gray. Swartland noted that this initiative was founded by Faizil Jakoet, an executive at Allan Gray, and the awards ceremony, in part, celebrates the continued partnership between the UFS and Allan Gray. This enduring relationship has thrived for over a decade, despite changes in leadership, creating opportunities for meaningful engagement between Allan Gray and UFS students. Swartland further emphasised the importance of this bond, saying, ‘’Another special relationship is formed every time we visit the UFS, between us and you, a lot of exceptional students.” 

As the event approached its conclusion, the audience had the privilege of hearing from guest speaker Liz Letsoalo, Founder of Masodi Organics, a prominent beauty and wellness brand. Letsoalo’s address centered on the ‘practicality of creating’, encouraging students to view themselves as creators, allowing them to pivot and adapt as their aspirations evolve. She urged students to stay dedicated to their dreams, emphasising that taking necessary actions and persevering is essential to turning their dreams into reality.

The Allan Gray Achievement Awards signify the remarkable achievements and potential of the UFS EMS Faculty students. This event not only celebrates academic excellence, but also reinforces the enduring partnership between the University of the Free State and Allan Gray, paving the way for further opportunities and engagement.

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.
