Lacea Loader, an award-winning communications professional.

Lacea Loader is an award-winning communications professional who heads the UFS Department of Communication and Marketing as Director. She works with a multi-talented team that takes care of all aspects of corporate communication and marketing at the UFS. 

What is the best thing about your job?
Having a portfolio that is ever-changing and that provides me with a broad perspective of the university’s business, which is enriching and insightful. Most of all, I enjoy the people I work with in every area of my job. In general, I stand amazed at the commitment and dedication of our staff, especially during the national lockdown. It has been encouraging to experience how my team has grown and developed their skills and transitioned to the virtual workspace during this time.  

What is the best and worst decisions you have ever made?
I learn from every decision, whether it has a good or challenging impact on my life. Marrying my best friend from school and raising two beautiful, strong, and independent children are the best decisions I could have made.

What was/is the biggest challenge of your career?
The balancing act. Balancing work life and personal life; this remains a challenge throughout my career. I am trying, but I still don’t get it right!

What does the word woman mean to you?
Being able to be powerful and assertive, yet kind, gentle, compassionate, vulnerable, and understanding at the same time. 

Which woman inspires you, and why?
I work with a team of exceptional women leaders who inspire me every day. Many women at our university have reached incredible heights and put the institution on the national and international stage with their achievements. I salute all my women colleagues in whatever role they play. Also, my involvement with professional organisations and international awards programmes has given me the opportunity to work with so many women across the world in the field of communication and marketing who are making a difference in our profession. 

What advice would you give to the 15-year-old you?
Grab the opportunities that may come your way, and always think of ways to enrich yourself personally and as a professional. Remember that your character is like a tree and your reputation is like its shadow. The shadow is what others think of you; the tree is the real you.

What is the one self-care thing that you do? 
I make time to drink tea, and lots of it! Walking with my husband, spending time with my family and friends, camping and enjoying nature are some of my favourite things.

What makes you a woman of quality, impact, and care?
My intuition and sixth sense, positive mindset, and deep belief that nothing will get me down. If you ask my children, they will say it is my work ethic – as it inspires them in their studies, my kind heart, and my resilience. 
 
I cannot live without … my music playlist and a good night’s sleep.
My secret weapon is … knowing when to pause and to take time out.
I always have … a plan B.
I will never … jump from anything higher than five times my length.
I hope … to visit Easter Island, Alaska, and Norway.

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.
