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.

Tiny microbes may solve large problems of water contamination, says Prof Esta van Heerden
2014-12-08

Small solutions for big problems

According to Prof Esta van Heerden, professor in the Department of Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS), this might hold some truth in current terms of water treatment strategies for waste and industrial effluents.

“There is little doubt in popular literature that eminent water crises are looming, not only with respect to the supply, but quality and effectiveness of various treatment options as well. The UFS’s Department of Microbial, Biochemical and Food Biotechnology is partnering with the Technology Innovation Agency to evaluate water treatment technologies that are applied worldwide and to extend these new or adapted options to innovative and interested clients in South Africa,” says Prof Van Heerden.

“The research focuses on using extreme microbes to tackle big contaminations and the results are amazing,” says Prof Van Heerden.

These microbes are fast becoming the stars on sites and developing these exciting systems allows for greener treatment options. It is fascinating that they can deal with metals, including chromium and uranium, cyanide, petroleum and diesel.

Of utmost importance is the development of a treatment for acid mine drainage.

“Interests have been overwhelming and thus far partners have allowed pilot scale development on their sites with very promising results. These initiatives are driven by responsible partners who strive to be innovative and develop sustainable technologies for good quality water that can be released in the environment,” Prof Van Heerden says.

The research group has set up a pipeline to serve the water communities’ needs. It provides an accessible toolkit for water analysis. A tailor-made treatment option is also developed and showcased in the laboratories. It has the added benefit that Geosyntec Consultants, USA, will ensure faster roll-out by sharing their vast experience on any related aspects.
