An ode to the Odeion String Quartet

30 January 2025 | Story Jacky Tshokwe | Photo Supplied

In the world of music, certain instruments resonate not just with sound, but with profound emotion and history. For Samantha Durrant, her journey with the violin began at the tender age of seven, inspired by the heartfelt story of Music of the Heart. This film, coupled with her exposure to the harmonious symphonies of the KwaZulu-Natal Philharmonic Orchestra, planted seeds that grew into a lifelong devotion to the violin and classical music.

Now, as part of the Odeion String Quartet – the only quartet in residence at a South African university – Durrant stands at the forefront of a mission that transcends performance. She sees her role not only as a performer, but as a steward of South Africa’s string-playing legacy. Her vision is bold yet grounded: to make the Odeion String Quartet the centrepiece of string training and performance in the country.

Reflecting on her journey, Durrant emphasises the critical role of mentorship, exposure, and perseverance. "There wasn’t one pivotal moment in my career," she shares. "It was the culmination of experiences with colleagues, mentors, and friends, all encouraging me to push my boundaries."

The Odeion String Quartet is bridging South African talent with global excellence, performing works by masters such as Haydn and Beethoven while celebrating contemporary compositions, including those from South Africa's rich tapestry of composers. For Durrant, the opportunity to collaborate with living composers is an unparalleled gift, offering insights into their inspirations and musical intentions.

Education and community are at the heart of the quartet's mission. Through school concerts, youth orchestra engagements, and performances at prestigious events such as the Vice-Chancellor’s Concert and the Rector’s Farewell, the quartet inspires audiences of all ages. "Youth orchestras represent unity," Durrant notes. "They bring people together, showcasing our shared humanity."

To those stepping into the challenging world of music, Durrant offers sage advice: "Be patient with yourself. Understand that this field is not easy, but the journey of self-discovery it offers is unparalleled."

With a packed performance calendar and ambitious goals for the quartet’s future, Durrant remains hopeful about music's place in society. "Music has the power to heal, inspire, and unite," she says. "In these challenging times, it is balm for the soul – an essential part of our humanity."

As the Odeion String Quartet continues its journey, its melodies remind us of the transformative power of music, resonating with hope and possibility across generations.

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.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast 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.
