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.

UFS hosts colloquium on technological higher education
2016-10-27

Description: Technology colloquium Tags: Technology colloquium

Prof Lew Zipin, Prof Sechaba Mahlomaholo,
Prof Marie Brennan and Dr Milton Nkoane,
attended the Faculty of Education’s colloquium
on the field of technological higher education
and its contribution to the knowledge society,
at the UFS Bloemfontein Campus. 

The University of the Free State’s (UFS) Faculty of Education, in collaboration with the Research and Development Unit from the Central University of Technology (CUT), hosted a colloquium on the field of technological higher education and its contribution to the knowledge society. Prof Marie Brennan and Prof Lew Zipin, both from Victoria University in Melbourne, Australia, presented the keynote addresses of the colloquium.

The past, present and future
The current fees protests in South Africa have caused universities to rethink and strategise new ways of delivering knowledge. Prof Brennan cautioned that when moving towards technological solutions for teaching, a crucial balance between past knowledge and practices and present and future knowledge and practices needed to be maintained.
“Knowledge is always dynamic, always generated from live problems, and therefore always relies on social interactions. Face-to-face interaction is removed by intense interaction with technology. If knowledge is presently linked to technology, we as academics must be able to move it. However, we should not neglect the indigenous knowledge that was generated through face-to-face interaction,” said Prof Brennan.
She purported that a reconnection between social relations and technology was important but to achieve this, a clearer pedagogical understanding of knowledge production was needed.

Never simplify complex problems

Prof Zipin said academics were constantly seeking complex problems and therefore could not reduce the complexity of a problem to simplify it for students entering the higher education space.
“We need to become a knowledge society. Ideologies often sway us not to look at the complexities of knowledge otherwise these ideologies would not be persuasive,” said Prof Zipin.

Is the technological move counterproductive?
Prof Zipin also cautioned that the move towards technological means for transferring knowledge had its own drawbacks. Institutions are a knowledge economy and its product is human capital. However, producing graduates who catered only to a technological society created downward mobility.
“People’s jobs are replaced by technology. This causes wages to decrease significantly because of structural inequalities, the move towards tech-based schooling should be done cautiously,” said Prof Zipin.

Simplicity not the ultimate sophistication
Prof Zipin concluded by stating that higher education had a responsibility to give its students the best possible future, this could be done by creating hegemonic relationships between institutions of higher learning, government and the private sector. Academics needed to fill the gap and apply their knowledge by applying complexity to social issues and allowing the complexity of these issues to flourish, the professor said.
