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.

Meet our Council: Christo Dippenaar, 'n oud-Kovsie vir oud-Kovsies
2016-12-26

Christo Dippenaar knows the University of the Free State (UFS) very well. He started his studies at the UFS in 1992 and later obtained a BProc degree. During his years at university, he was Prime of Hendrik Verwoerd Residence (1994), served on the Student Representative Council in the portfolio Men Intern (1995), and in the following year he was Deputy President of the Student Representative Council. He was also residence head of the former Reitz Apartments.

A thorough knowledge of the university
Thanks to this broad background, he has a thorough knowledge of the university, its history, procedures, principles and its people. It is therefore no surprise that Dippenaar was elected to the Council by UFS alumni. Dippenaar, or “Dippies” as he is also known, has served on the Council since 2014. In addition, he has a child who is currently studying at the UFS and therefore he has more than just a theoretical interest in what is happening at the UFS.

He is of the opinion that, in his capacity as UFS councillor, he could be a true mouthpiece for former Kovsies.

"As councillor, I can ask the necessary questions to ensure fair and just treatment of all stakeholders."

A man with diverse interests
His legal knowledge also comes in handy in his role as councillor. Dippenaar was formerly employed at Honey Attorneys and at Horn and Van Rensburg, but in 2008 he started his own practice which is also operating in Lesotho.

He describes his wife, Hanlie, as his best friend and soul mate. His eldest son, Johann, is studying BSc Quantity Surveying at the UFS, while another son, Pieter, is in Grade 10 in Grey College. His daughter, Anneke, is in Grade 6 in Universitas Primary.

Asked about his passions, he says rugby and fine Brahman cross-breed cattle are equally attractive to him. Thus, a man with diverse interests and a highly demanding career, but also a former Kovsie with a passion for other former Kovsies and for his alma mater.
