Betsy Eister 2_read more — Keitumetse Betsy Eister says the information they provide is used by researchers “in conducting much-needed research aimed at contributing towards the knowledge base of South Africa, knowledge aimed at building our nation towards a developed country”.

The role of Keitumetse Betsy Eister, Director: Library and Information Services – who leads a diverse team of 65 staff members – is to ensure that the University of the Free State community has access to information. This is done to “support lecturers in teaching researched content to undergraduate and postgraduate students and to assist students in their learning expedition by supporting them towards academic success and life-long learning”. Giving an overview of the role of the UFS Library and Information Services, Eister adds that the information they provide is used by researchers “in conducting much-needed research aimed at contributing towards the knowledge base of South Africa, knowledge aimed at building our nation towards a developed country”. This information is also beneficial to support staff and the management of the university, who are using it to deliver well-researched services.

With a masters’ degree in Library and Information Services and working on her PhD, Eister is the right person to ensure that the right information gets to the right people. A mother of two and someone that colleagues look up to, there is much to learn about this UFS champion woman.

Tell us about yourself

I was born and bred in Thaba Nchu 56 years ago. I remain grateful and proud of the type of parents I had, who instilled in me the belief and love for education, a foundation that has grounded me and led me to where I am today.

I believe in the teachings of the late Steven Covey, one of which is “the main thing is to keep the main thing the main thing”. In short, he says you need to stay focused on what you choose to do. In staying focused, I prefer to be driven by principles that have proven to have worked well in humanity, such as the government’s batho pele principles, ubuntu principles, ethical leadership principles, and so on.

On being a UFS staff member

I am proud of the 10 years I have spent as a Kovsie, with staff members who always remind me about the positive contributions I have made in their lives. Many of them have worked on their qualifications, some have obtained their first degrees, while others have improved their qualifications. At this stage, I can safely say the UFS LIS is a learning organisation, with four of us busy with doctoral studies, four with master’s studies, three with their honours, and six with their first degrees. We have also been working on our research capabilities, with two articles already published.

Advice to her 15-year-old self

Looking back, I see a little girl who fortunately made the right choices in life. The most important one was to listen to my parents. I went to a girls’ high school, the St Anne’s High School. At one stage, we performed the Bible story, Joseph and the Amazing Technicolour Dreamcoat, and I played the role of one of Pharaoh’s dancers. I developed a love for dancing and wanted to turn it into a career. My parents advised me to get my education first; I wasn’t very pleased with that, but I listened to them. I am glad that this 15-year-old worked on her education; I believe I would never have been the self-actualised woman I am today, given the dancing-career opportunities that were scarce for black people during those years. I believe education is key, whether you want to work as an employee or run your own business. It brings with it the maturity and knowledge required in both areas of productivity.

Women who inspires her

Prof Mamokgethi Phakeng, the UCT Vice-Chancellor. She is a classic example of what it means to spend the 24 hours we all have in a day; what you do with it depends on you. I see her using it to make an impact on a number of fronts within her circles of life, showing what ‘woman power’ is capable of. UCT students call her ‘Deputy Mother’, hooking up with them on social media. I, for example, join her every Sunday at 16:00 during her one-hour sessions, taking us through all aspects of postgraduate studies; this is for anyone to join, not only UCT students. She has now started sessions on building a career in academia. She seems to be living a balanced life, also making time for exercising and hiking.

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.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast 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.
