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.

Self-help building project helps to change lives

UFS PhD student Anita Venter did not know it in the beginning, but her doctoral research would eventually change her life and the lives of many others. 

The research was whether South Africa’s housing policies were socially and culturally responsive to grassroots reality in informal settlements. Venter agreed her research approach might have raised a few eye brows, but it was a journey she holds had more benefits than failures. 

Green living
For her case studies, Venter looked at ‘Start Living Green’ as a concept and further examined the implementation models of Earthship Biotecture Academy in New Mexico and Central America and the Long Way Home non-profit organisation in Guatemala. 

These groups train people with no specialised construction skills in applying and managing environmentally sound self-help building projects. Furthermore, their primary objectives were not building-related, but people-centred, with an advocacy role to create social, environmental and educational change through utilising the building technologies. 

It resulted in Venter signing up for a course in Guatemala to get the skills to implement her case studies here at home in Bloemfontein. 

An experimental mud, straw and waste material structure in her back yard grew into similar houses built in informal settlements, through the transfer of knowledge of indigenous building methods.  

Are rickety corrugated iron shacks only alternative?

Her case studies, one in Freedom Square in the Mangaung Metro Municipality, highlighted, among others, baffling tenure insecurities and “tangible conflicts” entrenched between Westernised and African perspectives on home ownership.

Venter says her thesis, in essence, did not oppose existing housing strategies but did challenge the applicability of an economically inclined model as the most appropriate housing option for millions of households living in informal settlements. 

The main findings of the case studies were that self-help building technologies and skills transfer could make a significant contribution to addressing housing shortages in the country; in particular in geographical locations such as the Free State province and other rural areas.

Venter’s own words after her academic endeavour are insightful: “These grassroots individuals’ courage to engage with me in unknown territories, gave me hope in humanity and inherent strength to keep on pursuing our vision of transforming informal settlements into evolving indigenous neighbourhoods of choice instead of only being living spaces of last resort.”

Positive results 
The study has had many positive results. The City of Cape Town is now looking at new innovative building technologies as a result. Most importantly Venter's study will open further discussions that necessarily challenge the status quo views in housing development.
