Natural Sciences at UFS receives R65 million equipment injection

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.

Kovsie student and reigning Miss Lesotho en route to Miss World 2015

2015-11-03

Relebohile Kobeli - the beauty queen of Lesotho

Relebohile Kobeli was crowned Miss Lesotho 2015 earlier this year, and is now en route to Miss World International 2015 in China to represent the mountainous Kingdom. The beauty pageant, which takes place between November and December, will see contestants from over 150 countries contending for the title.

The nineteen-year-old second-year Geography and Environmental Management student at the University of the Free State (UFS) also won Miss Lesotho in 2014. She holds other titles, such as Miss Outeniqua 2014, and First Princess Face of Lesotho 2013.

What would it mean to be the first from Lesotho to sit on the Miss World throne?

I believe that it would be a turning point for pageantry in Lesotho. We are one of the few countries that do not fully recognise pageants, and the value they add to the tourism industry. Winning the throne would be putting into practice the theory that we, as beauty queens in Lesotho, always practice what we preach.

Since beginning this Miss World contest, in what way have you reached out to your community through the Beauty with a Purpose project?

My Beauty with a Purpose project focuses mainly on introducing and helping start up sustainable projects in communities. I wanted to move away from giving people donations to giving them the skills to ensure their long-term livelihood.

What skill sets do you possess that are essential to succeeding as an international first queen?

I am a very creative individual who thinks on her feet. That is important for me because, when you are far away from home, should things go wrong, there's no room for panic. I am sociable and human-centered, I relate to different people, regardless of cultural differences, and, as an international queen, it is important to be appreciative of others’ way of life, regardless of how different it is are from your own.

Rolene Strauss, the current Miss World, stated her ambition to capitalise on promoting forgiveness, hope, and unity during her tenure. What are you hoping to achieve, given the chance as her successor?

I would definitely speak about self-reliance among young women and the youth at large. I come from a country where not everyone is lucky enough to get a job. In such cases, young men and women fall into crime, young women become victims of sexual abuse or prostitution, and, although one may argue that that is self-reliance, is it sustainable? Is it not escaping one fire to jump into another? It is important for me to represent every girl who has ever had a dream. I am spreading the message of possibilities when the world is yelling "Impossible!"

What has been the highlight of your term as Miss Lesotho?

My greatest highlight was finding myself through service to others. I discovered that the more I invest in myself, the more of me I can give and share.

The Miss Lesotho 2016 competition is around the corner, what words of wisdom would you like to share with hopefuls?

Pageantry is not all about pretty dresses and tiaras. It is hard work. Always be humble, and remember that, whatever the outcome, it is your life's journey. You are destined for greatness. Don't deny yourself that privilege.

In your experience, what is the Kovsie feeling referred to in the maxim “Only a Kovsie knows the feeling”?

It is the desire to want to be great, the motivation to live to my full potential.
