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.

Weideman focuses on misconceptions with regard to survival of Afrikaans

On the survival of a language a persistent and widespread misconception exists that a “language will survive as long as people speak the language”. This argument ignores the higher functions of a language and leaves no room for the personal and historic meaning of a language, said the writer George Weideman.

He delivered the D.F. Malherbe Memorial Lecture organised by the Department Afrikaans at the University of the Free State (UFS). Dr. Weideman is a retired lecturer and now full-time writer. In his lecture on the writer’s role and responsibility with regard to language, he also focused on the language debate at the University of Stellenbosch (US).

He said the “as-long-as-it-is spoken” misconception ignores the characteristics and growth of literature and other cultural phenomena. Constitutional protection is also not a guarantee. It will not stop a language of being reduced to a colloquial language in which the non-standard form will be elevated to the norm. A language only grows when it standard form is enriched by non-standard forms; not when its standard form withers. The growth or deterioration of a language is seen in the growth or decline in its use in higher functions. The less functions a language has, the smaller its chance to survive.

He said Afrikaans speaking people are credulous and have misplaced trust. It shows in their uncritical attitude with regard to the shifts in university policies, university management and teaching practices. Afrikaners have this credulity perhaps because they were spoilt by white supremacy, or because the political liberation process did not free them from a naïve and slavish trust in government.

If we accept that a university is a kind of barometer for the position of a language, then the institutionalised second placing of Afrikaans at most tertiary institutions is not a good sign for the language, he said.

An additional problem is the multiplying effect with, for instance, education students. If there is no need for Afrikaans in schools, there will also be no  need for Afrikaans at universities, and visa versa.

The tolerance factor of Afrikaans speaking people is for some reasons remarkably high with regard to other languages – and more specifically English. With many Afrikaans speaking people in the post-apartheid era it can be ascribed to their guilt about Afrikaans. With some coloured and mostly black Afrikaans speaking people it can be ascribed to the continued rejection of Afrikaans because of its negative connotation with apartheid – even when Afrikaans is the home language of a large segment of the previously oppressed population.

He said no one disputes the fact that universities play a changing role in a transformed society. The principle of “friendliness” towards other languages does not apply the other way round. It is general knowledge that Afrikaans is, besides isiZulu and isiXhosa, the language most spoken by South Africans.

It is typical of an imperialistic approach that the campaigners for a language will be accused of emotional involvement, of sentimentality, of longing for bygone days, of an unwillingness to focus on the future, he said.

He said whoever ignores the emotional aspect of a language, knows nothing about a language. To ignore the emotional connection with a language, leads to another misconception: That the world will be a better place without conflict if the so-called “small languages” disappear because “nationalism” and “language nationalism” often move closely together. This is one of the main reasons why Afrikaans speaking people are still very passive with regard to the Anglicising process: They are not “immune” to the broad influence that promotes English.

It is left to those who use Afrikaans to fight for the language. This must not take place in isolation. Writers and publishers must find more ways to promote Afrikaans.

Some universities took the road to Anglicision: the US and University of Pretoria need to be referred to, while there is still a future for Afrikaans at the Northwest University and the UFS with its parallel-medium policies. Continued debate is necessary.

It is unpreventable that the protest over what is happening to Afrikaans and the broad Afrikaans speaking community must take on a stronger form, he said.
