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.

Renowned forensic scientist speaks at the UFS

It is necessary for more research to be done in the field of forensic science in South Africa. This is according to Dr David Klatzow, well-known forensic scientist, during a lecture delivered at the University of the Free State (UFS) last week.

The university is offering, for the first time this year, a BSc degree in Forensic Science in the Department of Genetics. This three-year degree is, among others, directed at people working for the South African Police Service on crime scenes and on criminal cases in forensic laboratories. Students can also study up to PhD level, specialising in various forensic fields.

There is no accredited forensic laboratory in South Africa. “It is time to look differently at forensic science, and to deliver research papers on the subject. In light of the manner in which science is applied, we have to look differently at everything,” Dr Klatzow said.

Dr Klatzow praised the university for its chemistry-based course. “Chemistry is a strong basis for forensic science,” he said.

A paradigm shift in terms of forensic science is needed. Micro scratches on bullets, fingerprints, DNA, bite marks – all of these are forensic evidence that in the past led to people being wrongfully hanged. This evidence is not necessarily the alpha and omega of forensic science today. DNA, which seems to be the golden rule, can produce problems in itself. Because a person leaves DNA in his fingerprint, it is possible that DNA is transferred from one crime scene to another by forensic experts dusting for fingerprints. According to Dr Klatzow, this is only one of the problems that could be experienced with DNA evidence.

“No single set of forensic evidence is 100% effective or without problems. Rather approach the crime scene through a combination of evidence, by collecting fingerprints, DNA, etc. It is also very important to look at the context in which the events happened.

“A person sees what he expects to see. This causes huge problems in terms of forensic science. For example, if a criminal fits the profile of the perpetrator, it doesn’t follow that this specific criminal is the culprit. It isn’t what we don’t know that gives us trouble, it’s what we know that isn’t so,” Dr Klatzow said.
