Geraldine Lengau, Senior Officer in the UFS Gender Equality and Anti-Discrimination Office within the Unit for Institutional Change and Social Justice, calls on men to take the lead in ending gender-based violence.

Gender-based violence is a phenomenon deeply rooted in gender inequality and the scourge continues to be one of the most notable human rights violations, with many communities – especially women and children – suffering the most from the atrocious acts. 

South Africa remains the country with the highest number of violent acts, especially against women, and Statistics South Africa reports that one in five partnered women has experienced physical violence. 

Gender-based violence can take many forms, including 

• sexual harassment; 
• rape and/or sexual violence;
• stalking (deliberately and repeatedly following, watching, and/or harassing another person);
• physical, emotional, and economic abuse; and
• child abuse.

Geraldine Lengau, Senior Officer in the Gender Equality and Anti-Discrimination Office within the Unit for Institutional Change and Social Justice, says: “Individuals must be vigilant of toxic environments where emotional and physical abuse are rampant.”

 “Even in the workplace, individuals can experience gender-based violence and it can play itself out in the form of power dynamics, prejudice, and discrimination.”

To help end gender-based violence at work, Lengau says, “Institutions have a duty to implement policies and procedures to increase awareness and sensitisation about this pandemic.”

Societal norms often contribute to victims deciding not to report these criminal acts for fear of being judged, with many women still being considered guilty of attracting violence against themselves through their behaviour.

“It is important for communities to provide support to victims and for organisations to have a zero gender-based violence tolerance policy. Victims must report any act, and in extreme cases, they must not be shy to get a protection order,” Lengau says. 

With the 16 Days of Activism for No Violence against Women and Children Campaign in full swing, Lengau says, “It is a great international initiative to tackle and raise awareness around issues of gender-based violence; however, it is not enough. It should go beyond the 16 days.”

 “To rid society of gender-based violence, our communities – men and women – should work together to root it out. Men should take the lead in tackling issues and bringing about solutions. Women should never get tired of speaking out; there is help for them.”

“Gender-based violence is a societal ill and women need to know that they should not bear the shame,” she says.

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.
