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 academics serve high in ranks of Cereal Science institutions
2017-10-10

Description: Cereal Science Tags: Cereal Science

Dr Angie van Biljon, Senior Lecturer in the Department of Plant Sciences at the University of the Free State (UFS), was elected as president of Cereal Science and Technology South Africa (CST-SA) at their bi-annual general meeting, in Pretoria.

Prof Maryke Labuschagne, Professor in Plant Breeding at the UFS and official representative of South Africa in the American Association for Cereal Chemists International from 2007, was re-elected as the South African representative to the American Association for Cereal Chemists. She attends the annual conference in the US as well as the International Association for Cereal Science and Technology (the European counterpart of AACC) regularly. “I use these conferences to report on the research done by the research team at the UFS on gluten protein, baking quality and nutritional value of cereals,” she said.

Prof. Labuschagne was also involved in a training course for the baking industry. 

Both Dr Van Biljon and Prof Labuschagne are involved in research on wheat gluten proteins, which is critical to the baking industry. CST-SA is a platform to disseminate this and other research, not only locally but also internationally. The aim of this society is to advance cereal science and technology both in the public sector and in the industry of Southern Africa.

CST-SA creates an opportunity for staff and
students working on cereals to interact
with the industry. This prevents research
from being just academic and creates
an opportunity to bring the research and the
industry together.

Wheat research not just academic
According to Prof Labuschagne CST-SA creates an opportunity for staff and students working on cereals to interact with the industry. This prevents research from being just academic and creates an opportunity to bring the research and the industry together. This has been very useful for students at the university working on cereals, as they have made presentations at the “New Voices” symposium, a forum for postgraduate students to present their research.

“Through CST-SA we have also, through the years, presented our research on an international level at the annual meetings of the American Association for Cereal Chemists and the International Association for Cereal Science and Technology,,” said Prof Labuschagne.

The science of cereals
CST-SA is an association of organisations and individuals, from both the private and public sectors, who are actively involved in the science and technology of cereals. Its aim is to promote the dissemination of knowledge and information on cereal science and technology through meetings, publications, workshops and other means. CST-SA also organises training courses for the industry. In the past years there was a course for the baking industry and one for the milling industry and also the “New Voices” symposium”.
