The Centre for Microscopy (CFM) in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) unveiled a sophisticated JEOL High Resolution Transmission Electron Microscope (HRTEM) during a two-day microscopy conference on 14 and 15 March 2023. The microscope is part of a larger investment into research equipment worth R65 million.

Speaking at the opening of the conference, Prof Corli Witthuhn, out-going Vice-Rector: Research and Internationalisation, said the microscope purchase “is a significant milestone in the university’s bid for cutting-edge research”. The HRTEM is part of a larger consignment of JEOL equipment at the UFS and, according to Dr Sarah Harper from JEOL UK, it places the UFS in a unique position.

UFS at the forefront in using electron microscopes

The HRTEM microscope can be utilised across disciplines and will give the UFS an advantage in uncovering new solutions and creating national and international interdisciplinary research collaborations. “The UFS is at the forefront in this field in SA and continues to push the boundaries,” Prof Witthuhn said. This move will also positively impact the training of honours, master’s, and doctoral students.

Prof Danie Vermeulen, Dean of the Faculty of Natural and Agricultural Sciences, reiterated Prof Witthuhn’s sentiments by saying that this equipment will set the faculty apart from its competitors. “The faculty already reached the goals of Vision 130 by being proactive,” he said. In the past seven years more than R300 million worth of equipment was acquired by the faculty, but he added that to be the best is not just about the best equipment – “the data coming from using this equipment is what will make the real difference”.

Road to the JEOL HRTEM started in 2018

The process of acquiring a HRTEM microscope started in 2018 and was concluded with the purchasing of the JOEL microscopes in March 2020, a few weeks before the first COVID-19 lockdown. The purchase was made possible through the collaboration between the faculties of Natural and Agricultural Sciences and Health Sciences. Thanks to the dedication of staff members in the Centre for Microscopy and Physics, it was possible to accept delivery of the new HRTEM in June 2021. Prof Koos Terblans, Head of the Physics Department and the Centre for Microscopy, who led the entire project, said this was one of the “proudest moments in my career”.

Installing the equipment involved various university resources, including the University Estates Department, which had to make additional structural changes to the room where the equipment is housed. This included digging two metres into the existing floor and placing the HRTEM on a 70-tonne solid concrete block, to ensure that the equipment was secure and vibration free.

Prof Terblans said now that the HRTEM from JEOL and its supporting equipment – the final piece of the R65 million research investment puzzle – is part of the faculty’s resources, it is up to the scientists and academics to utilise it for innovative research, enhance research productivity, and foster new collaborations.

To be an ambassador for the University of the Free State (UFS) is a goal of the Odeion String Quartet (OSQ) and that is exactly what it will do through international visits to Tanzania and Austria. The OSQ, the only residential university quartet in South Africa, will play concerts abroad, share knowledge and build relationships.

It visits Dar es Salaam, Tanzania, from 17 to 20 November 2016 and Austria from 29 November to 4 December 2016. The quartet, which constitutes string lecturers at the Odeion School of Music, consists of Samson Diamond, Sharon de Kock, Jeanne-Louise Moolman and Prof Anmari van der Westhuizen Joubert.

A humbling experience
The OSQ was invited by Hekima Raymond, founder and conductor of the Dar Choral Society, to Tanzania to assist the symphony orchestra. Raymond is a self-taught pianist and conductor and was nominated for a BBC Outlook Inspirations award in 2016.

The quartet will lead the string sections of the orchestra, consisting of members from Uganda, Kenya and Tanzania, performing Beethoven’s fifth symphony and Verdi’s Requiem.

According to Diamond it is a humbling experience, an opportunity to extend their services and help establish the Dar Choral Society. “You are part of something really special, because the circumstances are remote if you compare it to what we have here.”

He means it is important to have a real African footprint and being involved there can later serve as a platform for UFS recruitment.

“You are part of something really special,
because the circumstances are remote if
you compare it to what we have here.”

South African and Austrian collaboration
According to Prof Van der Westhuizen Joubert it is an honour to play in Austria, as Europe is a centre for classical music. The OSQ will play concerts at the Alte Schmiede, Vienna, and the University of Salzburg.

The concert on 4 December 2016 at the University of Salzburg’s Mozarteum is a highlight because the UFS will have the opportunity to build relationships with the famous music school.

Prof Van der Westhuizen Joubert said it would be a South African/Austrian collaboration. “We will bring them South African works (Mokale Koapeng, AJ Feder, Arnold van Wyk and Peter-Louis van Dijk) and will be playing Austrian contemporary string quartets.”
