The University of the Free State (UFS) has joined The Conversation Africa (TCA) as a funding partner.  TCA, a not-for-profit media initiative, is part of a global platform that publishes articles written by academics and researchers.  The platform’s objective is to make the knowledge produced in the academy accessible, easy to understand, and freely available to the general public. Articles are published daily on the TC-Africa website - https://theconversation.com/africa. 

The platform uses a Creative Commons republishing model. This means articles can be republished by other media on the continent and internationally, ensuring even greater reach to audiences including academics, policy makers, funders, and the general public. 

To date, more than 55 UFS researchers and academics have published with TCA, and their articles have garnered more than 1,3 million readers globally. UFS researchers and academics are encouraged to publish with The Conversation. 

As part of the partnership, TCA will run writing workshops for UFS academics and researchers who want to enhance their writing and science communication skills. Dates for these will be announced soon.

How you can publish with The Conversation Africa

• Engage with The Conversation Africa editors when they contact you directly to write about your research area and expertise. The articles are short, ± 800 to 1 000 words.

• Pitch your idea for an article directly to The Conversation Africa here   

• Register as an author, and set up a profile

• Engage with the Communication and Research offices. Every week, The Conversation Africa sends an expert request for expert authors on topical issues to the Communication and Research offices, which can identify researchers. 
- Interested researchers are put into contact with the relevant editor at The Conversation to discuss the potential article

Why should you get published on The Conversation Africa?

Benefits for researchers and academics:

• Articles on the platform help to raise the profile of academics, often leading to policy engagement with governments, businesses, industry or professional bodies, conference invitations, academic collaborations, and further media exposure. 
• In the course of writing, academics get bespoke editorial assistance from the team working in consultation with them. 
• The opportunity to take part in a hands-on science communication writing workshop.
• Readership and republication metrics for each published article.
• A global readership with up to 1,2 million readers monthly.

Benefits for Communication and Marketing and the Research office:

• Provides well-curated, ready-to-use communication material for websites and social media. 
• Helps to profile the work of the university for marketing, communication, and awareness.
• Provides media exposure to the talent pool of UFS academics and researchers. 

Benefits for and across the university:

• Shines a spotlight on the excellent research and innovation at the UFS.
• Demonstrates the UFS’ commitment to facilitating greater engagement with society and promoting interdisciplinary communications.
• Visibility for the institution and researchers nationally and globally.
• Access to institutional analytics, including detailed data on the content published by UFS researchers.

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.
