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.

South Campus delivers out-of-the-box solutions

The IDEAS Lab on our South Campus supports learners in 83 schools by means of academic videos transmitted via the Internet Broadcast Project (IBP) and its own custom-built All-in-One (AIO) device. The project is a collaboration between UFS and the Department of Education in the Free State. It includes support for Mathematics, Physical Science, Life Science, Economics, Accounting, and Geography.

The AIO was purpose-built by the team at IDEAS Lab to facilitate the delivery of video lectures from highly-qualified teachers to identified schools. It comprises a projector, speakers, and a computer, which are housed in a custom-made, hard-wearing frame. The AIO is then set up at each school to which lessons are broadcast.

On-the-job training for educators

Educators have not been overlooked, either. UFS was the very first university to provide an Advanced Certificate in Teaching in a fully digital format, the ACT Online programme. It is designed for practicing teachers to upskill themselves in order to better address the needs in the classroom, not only advancing their career, but strengthening their knowledge, competencies, and subject specialisation as well. Ultimately, this leads to an improved quality of education, which has a profound impact on multitudes of students around South Africa.

CSIR joint initiative

Coupled with these projects is a new joint initiative termed ICT For Education. This project sees the CSIR collaborating with the national Department of Education, the Department of Rural Development and Land Reform, and the UFS. For this project, 24 primary and secondary schools in South Africa were identified to promote technological advancement in the education sector. Tablet computers have been allocated and already deployed at these schools, to learners as well as nearly 400 teachers.

South Campus is involved in the training of the teachers and learners in the use of the tablets in the classroom and other educational opportunities. In addition, training for 48 unemployed young people who will be providing first-line support began in March at a school in Thaba Nchu. The course on IT support is structured in such a way that anyone in the community can take it, starting out with topics such as My role in the community.
