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.

Ghanaian academic speaks about next generation of African scholars

Prof Akosua Adomako Ampofo, one of the Centre for Africa Studies’newly-appointed advisory board members, addressed students and staff on 3 October 2013. Her topic Are you the scholar Africa needs?enthralled the audience with the passionate way in which she argued for nurturing activist-scholars rather than scholars who simply produce knowledge for the sake of it. “It is more urgent than ever before that … we do not simply see our roles as researchers and teachers, but that we are committed to impacting our communities” for the better – also by “making our knowledge production globally visible,” she argued. Africa is said to contribute less than 0.5 percent of the world’s scientific publications. The fact that most of these – and nearly all of the social science production – emanate from just three nations (Egypt, Nigeria and South Africa) means that many countries are absent from the radar.

According to her, the next generation of African scholars will have to compete within a hostile terrain where private universities are proliferating and costs of higher education are on the rise. These scholars will have to possess 22nd century skills, but a 20th century heart and sensitivity for the continent and its people.

Drawing on Kwame Nkrumah, Prof Ampofo proposed three guiding principles for becoming the scholars Africa needs. Firstly, by having a passion for knowledge as well as an Africa-centred knowledge – “nobody can tell our stories better than we can.”. Secondly, to translate our research into outputs not only in the form of internationally-recognised publications, but also in popular sources that will be read by a much wider public. And lastly, to carrying the torch for teaching and learning in the classroom – preparing our students to serve Africa or, as Nkrumah said, producing “devoted men and women with imagination and ideas, who, by their life and actions, can inspire our people to look forward to a great future.”.

Akosua Adomako Ampofo is a Professor of African and Gender Studies, and Director of the Institute of African Studies at the University of Ghana, Legon. An activist-scholar, her current work addresses African knowledge systems; race, ethnicity and identity politics; gender-based expressions of violence; constructions of masculinities; women and work; and popular culture. She is currently co-editing a volume titled, Transatlantic Feminisms: Women and Gender in Africa and the African Diaspora.In 2010, she was awarded the Sociologists for Women in Society Feminist Activism Award.
