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.

Artistic development at UFS to transform the face of Bloemfontein creatively
2015-07-02

The 7-metre high ‘Urban Fox’ is one of Alex Rinsler's artworks adding a fragment of the wild to the city of Shanghai in China.

Bold, bright, and beautiful public art sculptures are in the inception phase at the university’s Bloemfontein Campus. Manchester-based public artist, Alex Rinsler, of the Programme for Innovation in Artform Development (PIAD)’s forum for artist development, is to install three enthralling sculptures in the city of Bloemfontein.

The PIAD forum for artist development is an initiative of the Vrystaat Arts Festival, formerly known as the Vryfees, which aims to celebrate art in the Free State by hosting experimental art practices. In its capacity as a PIAD partner, the University of the Free State promotes increased access to, and participation in, culture as a form of human development.

Presenting an artist’s talk titled ‘Urban Safari: Art in public space,’ on the Bloemfontein Campus recently Rinsler introduced himself and his creative ideas to students, staff, and the public at the Johannes Stegman Art Gallery. The talk served as an invitation to the active participation of Bloemfontein citizens in all phases leading to the installations. Dispersed across the Mangaung Metropolitan, the giant sculptures are intended to capture and reflect different aspects of the community’s lived experiences. 

As a public artist based in the United Kingdom (UK), Rinsler has exhibited in cities nationally and internationally, with the intention of bringing a touch of the wild to urban lives. His vision is to witness the development of cities into cultural boulevards, and explore “what we can do to bring back the sense of nature, the wild” by adding new symbolism to urban lifestyle.

“I believe in creating work accessible to the public, which stimulates conversation,” said the Clore Leadership Programme Fellow (University of Manchester) and Founder of Pirate Technics - an artistic practice company.

In 2012, he worked with 31 Master’s students from 24 countries on an icon for global peace named “Under the Baobab” in London. The colourful and magnificent Baobab tree made from pieces of fabric representing distinct cultures told the story of migration to London.

Rinsler is determined that the Bloemfontein “project, similar to the London installation, will create imagery that people will remember.”

Dr Ricardo Peach, Director of the Vrystaat Arts Festival and PIAD, hopes the project fosters diversity while producing a “communal cultural product." 

“What I know about Alex’s work is that he will be working with what he calls a self-selected community, people who are interested in this, and who want to work together to build these sculptures, as part as a process for them to get a sense of where they belong, and their input into the city. It’s about people telling their own stories.”

The public installations are a way of transforming the landscape, and connecting people of “a place like Bloemfontein where communities are often still so divided,” said Peach.
