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.

MSc student plans to FEED our hungry planet

Since attending the 2014 Youth Ag-Summit in Canada, Lisa Coetzee – an MSc student in Plant Pathology in the Department of Plant Sciences at our university – developed a plan to address hunger:

FEED – Forum of Education, Empowerment and Development.

Coetzee, together with a junior lecturer at Plant Sciences, Marguerite Westcott, started this student association to tackle the issue of food insecurity head-on.

Education, empowerment and development “are keywords vital to the solutions to poverty. Hunger is an issue which is found in our own homes. One in every four South Africans is food insecure. Hunger kills more people every year than Aids, malaria and TB combined,” says Coetzee.

“This forum allows awareness to be raised about the hunger situation locally and globally. FEED is talking about hunger and it is assisting in reducing it by reaching out to communities which are in need.

“FEED is the generation which is going to make a difference in eradicating hunger,” Coetzee continues. “We want students to think about how they can feed the hungry through what they are studying”. For Coetzee it is a high priority to ensure that the youth are aware of the importance to feed our hungry planet in a sustainable way.

Her philosophy on relieving hunger and increasing food safety is to enhance the efficiency of crop production, ensure crop security and reduce mycotoxins in the food we eat.

During the 2014 summit, Coetzee was elected to represent the African delegates on the Youth Ag Summit Committee. Ever since, she has been enthusiastically active in the agricultural community. As 43% of the globe’s farmers are women, Coetzee also feels she acts as a voice for female farmers in South Africa.

An important lesson Coetzee has learned is that there is power in one person to make a change – that we should start small but think big.
