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.

Heart diseases a time bomb in Africa, says UFS expert
2010-05-17

 Prof. Francis Smit

There are a lot of cardiac problems in Africa. Sub-Saharan Africa is home to the largest population of rheumatic heart disease patients in the world and therefore hosts the largest rheumatic heart valve population in the world. They are more than one million, compared to 33 000 in the whole of the industrialised world, says Prof. Francis Smit, Head of the Department of Cardiothoracic Surgery at the Faculty of Health Sciences at the University of the Free State (UFS).

He delivered an inaugural lecture on the topic Cardiothoracic Surgery: Complex simplicity, or simple complexity?

“We are also sitting on a time bomb of ischemic heart disease with the WHO (World Health Organisation) estimating that CAD (coronary artery disease) will become the number-one killer in our region by 2020. HIV/Aids is expected to go down to number 7.”

Very little is done about it. There is neither a clear nor coordinated programme to address this expected epidemic and CAD is regarded as an expensive disease, confined to Caucasians in the industrialised world. “We are ignoring alarming statistics about incidences of adult obesity, diabetes and endemic hypertension in our black population and a rising incidence of coronary artery interventions and incidents in our indigenous population,” Prof. Smit says.

Outside South Africa – with 44 units – very few units (about seven) perform low volumes of basic cardiac surgery. The South African units at all academic institutions are under severe threat and about 70% of cardiac procedures are performed in the private sector.

He says the main challenge in Africa has become sustainability, which needs to be addressed through education. Cardiothoracic surgery must become part of everyday surgery in Africa through alternative education programmes. That will make this specialty relevant at all levels of healthcare and it must be involved in resource allocation to medicine in general and cardiothoracic surgery specifically.

The African surgeon should make the maximum impact at the lowest possible cost to as many people in a society as possible. “Our training in fields like intensive care and insight into pulmonology, gastroenterology and cardiology give us the possibility of expanding our roles in African medicine. We must also remember that we are trained physicians as well.

“Should people die or suffer tremendously while we can train a group of surgical specialists or retraining general surgeons to expand our impact on cardiothoracic disease in Africa using available technology maybe more creatively? We have made great progress in establishing an African School for Cardiothoracic Surgery.”

Prof. Smit also highlighted the role of the annual Hannes Meyer National Registrar Symposium that culminated in having an eight-strong international panel sponsored by the ICC of EACTS to present a scientific course as well as advanced surgical techniques in conjunction with the Hannes Meyer Symposium in 2010.

Prof. Smit says South Africa is fast becoming the driving force in cardiothoracic surgery in Africa. South Africa is the only country that has the knowledge, technology and skills base to act as the springboard for the development of cardiothoracic surgery in Africa.

South Africa, however, is experiencing its own problems. Mortality has doubled in the years from 1997 to 2005 and half the population in the Free State dies between 40 to 44 years of age.

“If we do not need health professionals to determine the quality and quantity of service delivery to the population and do not want to involve them in this process, we can get rid of them, but then the political leaders making that decision must accept responsibility for the clinical outcomes and life expectancies of their fellow citizens.

“We surely cannot expect to impose the same medical legal principles on professionals working in unsafe hospitals and who have complained and made authorities aware of these conditions than upon those working in functional institutions. Either fixes the institutions or indemnifies medical personnel working in these conditions and defends the decision publicly.

“Why do I have to choose the three out of four patients that cannot have a lifesaving operation and will have to die on their own while the system pretends to deliver treatment to all?”

Prof. Smit says developing a service package with guidelines in the public domain will go a long way towards addressing this issue. It is also about time that we have to admit that things are simply not the same. Standards are deteriorating and training outcomes are or will be affected.

The people who make decisions that affect healthcare service delivery and outcomes, the quality of training platforms and research, in a word, the future of South African medicine, firstly need rules and boundaries. He also suggested that maybe the government should develop health policy in the public domain and then outsource healthcare delivery to people who can actually deliver including thousands of experts employed but ignored by the State at present.

“It is time that we all have to accept our responsibilities at all levels… and act decisively on matters that will determine the quality and quantity of medical care for this and future generations in South Africa and Africa. Time is running out,” Prof. Smit says.
