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.

Research at the University of the Free State (UFS) has indicated that nearly 60% of students are victims of food insecurity and suffer from hunger most of the time. The research by the UFS Faculty of Health Sciences shows that a further 25% are food insecure but are not hungry most of the time.

Senior Lecturer in the Department of Nutrition and Dietetics, Dr Louise van den Berg, says food insecurity is common among student populations across the world. However, local research shows that it is almost double that of tertiary institutions in developed countries.

Food insecurity among students caught many people off-guard
Dr Van den Berg says in South Africa nobody had really looked at the problem until recently “It seems student food insecurity has caught many people off-guard.” She says people tend to think of tertiary students as a privileged group.

The research has now indicated how deep the problem really is on campus. The students that most likely go hungry are single, male, black or coloured, and are generally first-generation students.

They are also mostly undergraduates, those paying their studies from non-bank loans or bursary means, those not living with their parents or guardians or those that need to support somebody else financially.

The results further indicate that those that are likely to suffer from hunger seldom or never have enough money for food but have to borrow money for food, have to ask for food, sell items to get food or steal food.

“A healthy student is a
successful student.”

Bursary money send back home for parents to survive
Dr Van den Berg agrees that one of the main reasons for the situation is economic stress. Research has shown students rarely spend money on food when resources are scarce. Furthermore, parents of students studying with bursaries are not always able to fully support them on campus. Some students send bursary money back home for their parents to survive.

She says other factors that contribute to campus food insecurity are that all over the world universities have terminated catered food halls due to high costs. “To a large extent this has created a food desert for students and now they need to look after themselves.”

To throw money at the problem does not seem to be the answer. 

Students are food-uncertain beings
The research indicates that young people on campus do not know where to buy food, much less the correct, nutritional food they need. Dr Van den Berg says most universities are now aware of the problem and have been taking steps. This includes teaching students how to budget and making them aware how important nutrition is for their success and their responsibility for themselves.

Universities are also looking at private funding for food aid and food schemes. Dr Van den Berg says other solutions are the restructuring of bursary fees, student self-help initiatives and food gardens.

The Faculty of Health Sciences is taking the initiative to manage a food blog on the UFS website. It will also use other social media platforms to post food-preparation videos and recipes for students.

Dr Van den Berg says it is important to grow the 15.6% group of students who indicated they are food secure because a healthy student is a successful student.
