The repositioning of The Journal for Contemporary History in the Faculty of the Humanities can be likened to the French word ‘renaissance’; maybe an overused cliché even in this lofty academic arena, but with a new editor, the journal will construct a new identity for itself and the faculty.

“In my view, this journal occupies an important place in the faculty’s strategy. It is not only a vehicle to promote interdisciplinarity and internationalisation, but also serves as an important space for building capacity,” said Prof Heidi Hudson, dean of the Faculty of the Humanities.

Prof Neil Roos, new editor of the journal, succeeds Prof Pieter Duvenage. He will steer the journal along with Prof Heidi Hudson and Dr Chitja Twala, Vice-dean of the Faculty of the Humanities.

On Thursday 14 February 2019, Prof Heidi Hudson, hosted a function on the Bloemfontein Campus of the University of the Free State to reset the journal’s agenda.

Finding a new focus

Prof Roos pointed out that the Journal for Contemporary History has a long history; it is an archive in itself because it contains published work which would probably not have been published elsewhere. He added that History as a discipline has changed over time and that “the journal needs to change to where the discipline finds itself these days”.

“It has been interdisciplinary, and it must remain that way, as it invites work from other fields. I would like to encourage submissions that cover a stronger theoretical engagement.”

Commenting on how the journal might be repositioned, Prof Roos said, “We can ground the journal in the Global South and soften the restriction that articles must come from sub-Saharan Africa”. Prof Roos is also of the opinion that this could encourage articles from other parts of the Global South, stimulate theoretical and comparative discussions beyond South Africa, and potentially enrich debates about history, politics, and global ethics. He suggested to the editorial board that the name of the journal be changed to the Southern Journal for Contemporary History. 

Making the journal a first choice for scholars across disciplines

The Journal for Contemporary History first appeared in 1975; until 2015, 94 issues have appeared, 764 articles and 240 book reviews were published, and the journal had five editors. “The journal has shifted from the histories of whites, while a growing number of liberation histories were included in the journal,” said Prof Roos.  Only essays with its empirical core focusing on sub-Saharan Africa since 1945, were considered. The journal was accredited by the Department of Higher Education in 1991.

Prof Roos insisted that in order to make this a journal of choice, “we must be quite clear about its identity and what it stands for”. It will retain and strengthen its current interdisciplinary feel, although all submissions will be expected to address the unique disciplinary feature of History, namely, the study of change over time. In addition, it will include a section for shorter review essays (dealing, for instance, with the regional or comparative historiographies of any number of topics; or the oeuvre of major scholars and commentators on the contemporary history of the Global South). Providing a platform for essays of this sort, or where several authors take on a particular theme, would further mark the journal’s unique identity.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
