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.

“I am primarily fascinated in the travelling or movement of images in different spaces and media. By moving images from one medium into another, or posting and reposting them in different urban and virtual spaces, I ask questions about media presence and space.”

According to the late artist Dot Vermeulen, this is what the work for her Master’s degree was about. She was still completing it at the Department of Fine Arts at the University of the Free State (UFS).

Her work, called Posting Presence, is currently on display at the Johannes Stegmann Art Gallery on the Bloemfontein Campus. The exhibition is running from 1-30 October 2015.

Vermeulen was a junior lecturer at the Department of Fine Arts before she passed away in a car accident in April 2015.

According to Angela de Jesus, curator of the UFS Art Galery, the exhibition would have been part of Vermeulen’s final evaluation for her Master’s degree. She was one of South Africa’s most promising young artists, and won the prestigious Sasol New Signatures art competition in 2013.

In the work she had done in Posting Presence, Vermeulen said the spaces represented were derived from areas under bridges in an urban space where the visual messages left, speak of an accumulation of movement.

Exhibition event

An exhibition event was held on Friday 16 October 2015 at the Johannes Stegmann Art Gallery to celebrate Vermeulen’s work.

Janine Allen-Spies
and Prof Suzanne Human, the supervisors of her Master’s degree,spoke about the work to those attending.

Catalogue


De Jesus said a catalogue of Vermeulen’s research for Posting Presence had also been compiled, and would be available at the UFS Sasol Library in order for others to “use her work for further research”.

•    Vermeulen’s work can be seen from 08:30-16:30 daily until 30 October at the Johannes Stegmann Art Gallery on the Bloemfontein Campus.
