In its quest to inspire excellence, the University of the Free State (UFS) is in the process of installing state-of-the-art microscopy instruments that will differentiate them as leaders in materials research.

This project to the value of R65 million will not only promote research in, among others, the fields of Chemistry, Physics, Microbiology, Geology, Plant Sciences, Zoology, and Cardiothoracic Surgery, but it will also increase the number of research articles published. 

Prof Koos Terblans, Head of the Department of Physics and Director of the Centre for Microscopy at the UFS, indicates that the university recently purchased a high-resolution transmission electron microscope (HRTEM), a scanning electron microscope (SEM), and a focused ion beam secondary electron microscope. 

“The installation of the equipment that was delivered on 1 March 2021 will take approximately three to six months,” he says. 

Research at another level

The biggest instrument, the HRTEM, allows for direct imaging of the atomic structure of samples. This powerful tool will allow researchers to study the properties of materials on an atomic scale. It will, for instance, be used to study nanoparticles, semiconductors, metals, and biological material.

The instrument will also be used to optimise heat treatment of materials, as it can heat the sample up to 1000 °C while recording live images of the sample. “With this apparatus, the UFS is the only institution in South Africa that can perform this function,” says Prof Terblans. 

He says to install the apparatus, they had to dig a hole of 2 m deep in a special room where the machine was to stand. The machine was then mounted on a solid concrete block (4 m x 3 m x 2 m) in order to minimise vibration. The instrument also acquired a special air conditioner that minimises the movement of air in the room. 

The focused ion-beam secondary electron microscope that was purchased, is used together with the HRTEM, explains Prof Terblans. It is used to cut out samples on a microscopic level to place inside the HRTEM. 

Having access to both the HRTEM and the ion-beam secondary electron microscope places the UFS at another level with its research, says Prof Terblans. 

At the forefront of microscopy 

The third machine acquired, the SEM – which is an electron microscope – allows researchers to produce images of a sample by scanning the surface of the sample with a focused beam of electrons. Prof Terblans says this machine will be used to serve researchers in the biology field with high-resolution SEM photos. 

The UFS Centre for Microscopy can, besides UFS researchers, be accessed by researchers from the Central University of Technology, the national museum, and other research facilities. 

With this injection of state-of-the-art equipment, the UFS is now more than ever at the forefront of research in South Africa.

“Greening my community and touching lives is my purpose in life. We were put on this beautiful Earth to serve others and make a difference in the world.”

This is what Elnè van Coller, final-year Occupational Therapy student at the University of the Free State, had to say after being selected as a national finalist in Miss Earth South Africa (SA) leadership programme.

She has set out to be the change. Not only does she want to see change in her own community but in the rest of the world. The reason she entered the Miss Earth SA programme is to inspire others.

Leadership programme to inspire others

The Miss Earth SA is a leadership programme which aims at empowering young South African women with the knowledge and platform to create a sustainable difference. It helps create awareness of sustainable development, the environment, wildlife, and the conservation of the natural legacy.

 “Miss Earth SA is an amazing platform for me to develop leadership skills, raise awareness, and be actively involved in environmental affairs as well as serving the community,” said Elnè.

Getting the community involved is important

The theme for this year’s Miss Earth SA programme is Waste Stops With ME, so clean-ups are a major part of the programme. Elnè started a Facebook page, Team Up-To-Clean-Up Bloemfontein. “This page is to share environmental facts, inform the people of Bloemfontein about the clean-ups, as well as get them involved”.

The Miss Earth SA gala week will take place in Johannesburg from 5 – 9 September 2016 when the Miss Earth SA 2016 will be announced.
