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.

Shimlas had the right attitude, says Scholtz

His rugby team had the right attitude to win in difficult conditions in Cape Town.

This is what Hendro Scholtz, Head Coach of Shimlas, had to say after the University of the Free State (UFS) started its Varsity Cup campaign on 8 February 2016 with a victory of 23-17 over Ikeys.

According to him, the UFS had to sweat hard until the end on a windy Green Mile, which has been the downfall of many opponents before. His substitutes also had a great impact.

Troublesome Cape wind

Shimlas have a tough draw this year, and to start in the Mother City was a huge task. Scholtz and his men have only three home matches and will play against most of the major teams in away matches.

“We knew it would be difficult in Cape Town. With the wind blowing as it does, one can't play as you would like to during the rest of the season,” the coach said.

“The guys had a will to win.”

The former Springbok believes that too much cannot be read from the first round results. The Shimlas will play their second match on 15 February 2016 against Tuks in Pretoria.

Replacements with good impact

Only the prop Rudolph Botha, flanker Fiffy Rampeta, and prop Teunis Nieuwoudt, who started against Ikeys, were involved in the 2015 final against Pukke.

Other big Shimla names, such as the prop Ox Nche, hooker Elandré Huggett, prop Conraad van Vuuren, and flanker Daniel Maartens, were sent onto the field in Cape Town after half-time.

“We had a plan with the replacements for the second half. They made a huge difference,” Scholtz said.

Rampeta was named Man of the Match, but it was Maartens and Co who turned the game in their team's favour in the second half.

Matsoele could be out of action for long

The Shimla fullback, Sechaba Matsoele, had to leave the game against Ikeys early because of a knee injury, and could be out of action for some time.

His scrumhalf, Zee Mkhabela, was also injured (by a blow to the head), so Shimlas will have to keep their fingers crossed for his quick recovery.

Scorers:
Shimlas 23 (7): Tries: Arthur Williams, Nardus Erasmus, Mosolwa Mafuma. Conversions: Stephan Janse van Rensburg (2).
Ikeys 17 (0): Tries: Khanyo Ngcukana, Nathan Nel. Conversion: Hilio de Abreu. Penalty: De Abreu.
Other results (home team first): Tuks 15, Pukke 38; UJ 19, Madibaz 12; Maties 40, CUT 0.
