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.

When entrepreneurship meets industrial innovation
2014-12-13

Internationally acclaimed Argicon Pelleting is a worldwide supplier of pelleting machinery and equipment as well as agri-processing factories. The company was established in 1993 by André and Johan Eksteen, UFS 2004 MBA graduate. After taking over sole ownership, the company grew from a one-man business to an internationally respected specialist in the design and manufacturing of pelleting solutions for the agricultural industry.

A common practice in industrial procedures, pelleting involves processing material into small dry pellets. This is used globally by manufacturers of animal feed or recycling facilities that specialise in processing materials for reuse. This process, however, can only be successfully accomplished with specialised equipment, namely a pelletizer. With fifteen years’ experience in agriculture, and international exposure in countries such as Uganda, Australia, Singapore and New Caledonia, this was not a tall order for Johan.

Agricon focuses on consistently developing innovative ways to add value to its offering. The business has successfully installed pelleting equipment for a range of products, including tobacco dust, rooibos tea, human sludge waste, organic fertilizers and vermi-compost. In addition to the manufacturing of machines and equipment, the company also provides training and on-site installation for clients, as well as support following a sale or the provision of spare parts. The company also provides advice on new product developments and business opportunities for clients within the sector.

Apart from doubling its sales between 2013 and 2014, the company gained great recognition within the industry. Johan was awarded the University of the Free State Business School’s Entrepreneur award in 2013 and he is the first-prize winner of the ILO Free State EnterPRIZE Job Creation Challenge for 2014. He is currently one of 15 finalists countrywide in the Entrepreneur of the Year competition sponsored by Business Partners and Sanlam. Johan is the mentor and stand-in manager for Almenta, a skills development company (winner of the ILO Best Social Entrepreneur for Skills Development award) and Equus Groom School (winner of the ILO Social Entrepreneur in Youth Development award).

Johan was also announced as the winner of the SA entrepreneur of the year for small businesses.
