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.

Research at the UFS on the acceptability and modern use of earth building in newly settled urban areas can help the poorest of the poor to acquire hou
2003-08-26

The University of the Free State and the Technische Universiteit van Eindhoven in the Netherlands received a research bursary of R316 000 from SANPAD (South African Netherlands Research Programme on Alternatives in Development).

The aim of the research is to determine the public acceptability of sustainable, high quality, earth constructed public and private buildings as an alternative to the conventional way of building with bricks and steel.

“European countries like the Netherlands are far advanced with studies in earth construction and this is why the partnership was formed with the Technische Universiteit van Eindhoven,” says Prof Das Steÿn, Head of Urban and Regional Planning at the UFS and project leader.

Although research regarding mapping, typology and availability of natural and local resources has been done on a national level, little research has been done on the acceptability and the modern use of earth building in newly settled urban areas.

“South Africa has a large housing shortage and traditional methods such as earth building techniques are not used in urban informal housing. Preference is given to corrugated iron sheets and plastic,” says Prof Steÿn.

The use of upgraded earth construction might be more sustainable as far as the environment and the economy is concerned. “If we can make a breakthrough in the development and propagating of these methods it will help the poorest of the poor to acquire housing of a better quality.”

The research team from the UFS consists of Prof Steÿn, Ms Petria Jooste-Smit, Head of the Unit for Earth Construction in the Department of Architecture and Mr Gerhard Bosman of the Department of Architecture.
