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.

"Service" needs to return to public service

There is a serious need for the concept of “service” to be reintroduced to the public service. In addition to this, public servants need to behave ethically and honestly if the public service were to achieve its main aim of service delivery to South African citizens and thereby also restore the trust of citizens in the state.

This was the central theme of the JN Boshoff Commemorative Lecture hosted by the Department of Public Administration and Management at the University of the Free State UFS). The lecture by Prof. Chris Thornhill, emeritus professor of Public Administration and Management at the University of Pretoria, focused on “Administrative and Governmental Challenges: Lessons from the Past”. He drew pertinent parallels with the administrative and governmental practices during the times of Pres. JN Boshoff, second president of the Orange Free State in 1855, and the challenges faced in this regard by the current government and public service.

Prof. Thornhill highlighted important aspects such as globalisation, the environment, public service and democratic government in his presentation.
He said the borders between countries have all but vanished and governments therefore have to carefully consider the effects of globalisation on its domestic affairs. The strength of a country’s currency, for example, was not only determined by how that country viewed or perceived it, but also by the international community’s perception of that country’s political and economic stability. This, in turn, could have serious implications for that country’s investment and economic prospects.

Governments are compelled to attend to the utilisation of its natural resources as these resources are finite and therefore irreplaceable. Policy interventions have to be introduced to decrease or regulate the use of certain natural resources or alternative measures need to be introduced. The example of bio-fuel production in various countries was highlighted.

He said the South African public service is characterised by three debilitating factors, namely the prevalence of corruption, the interference of politicians in administrative functions and a lack of appropriate skills and therefore a lack of commitment on the part of officials. In the municipal sector, for example, 46% of municipal managers have less than one year’s experience and this mainly occurs because of the practice of deployment (the appointment of a person based on political affiliation). An amendment to the Local Government: Municipal Systems Act is currently under consideration, in terms of which municipal managers will be disallowed to hold party political positions simultaneously.

According to Prof. Thornhill this is a step in the right direction, but more needs to be done to neutralise the impact of these debilitating factors in order to restore the credibility of the public service.

On democratic government Prof. Thornhill said the fact that the majority of a country’s citizens elect a political party to power does not automatically make the government capable of governing effectively and efficiently. It is therefore important for the rulers to understand their governing role within a democratic context, but more importantly to act accordingly. It is also important not to centralise power unduly as this could be a serious threat to accountable government. The 17th amendment to the Constitution, 1996, currently under consideration, and in terms of which national and provincial government will be allowed to intervene in local government matters, was highlighted as a case in point.

Prof. Thornhill said it was essential for those involved to sincerely and honestly and ethically deal with the above matters for the public service to overcome current challenges.
