Global Citizen Invitation Prof Thuli Madonsela 4 July 2024

The University of the Free State (UFS) and the South African Chamber of Commerce United Kingdom (SACC UK) are pleased to present a Global Citizen Series conversation, South Africa’s Future in Focus: the post-election impact on social justice, service delivery, higher education, and the economy, from the perspective of Prof Thuli Madonsela, Director of the Centre for Social Justice in the Faculty of Law at Stellenbosch University and Professor of Law in the Law Trust Research Chair in Social Justice Studies.

As part of the Global Citizen Webinar Series, Prof Madonsela – a member of the International Anticorruption Advisory Council and Global Justice Leaders – will join UFS Vice-Chancellor and Principal, Prof Francis Petersen, and SACC UK Chairperson, Sharon Constançon, for a conversation that explores what the future holds for social justice, service delivery, higher education, and the economy in South Africa.

After thirty years of democracy, South Africans once again made their mark on 29 May 2024 in one of the most pivotal elections since 1994. Join us in person during the Free State Arts Festival or online as we explore South Africa’s Future in Focus: The post-election impact on social justice, service delivery, higher education, and the economy.

Date: Thursday 4 July 2024
In-person event SA time: 18:00-20:00 SAST, Centenary Complex, UFS Bloemfontein Campus
Webinar SA time: 18:30-19:30 / UK time: 17:30-18:30

The livestream link will be shared with those who RSVP

About Prof Thuli Madontsela

Prof Thuli (Thulisile) Madonsela is the Director of the Centre for Social Justice (CSJ) in the Faculty of Law at Stellenbosch University and Professor of Law in the Law Trust Research Chair in Social Justice Studies. She is the founder of the Thuma Foundation for Democracy Leadership and Literacy and a member of the African Academy of Sciences. She was recently appointed to the UN Scientific Advisory Board and as Chairperson of Cities Alliance. She is a member of the International Anticorruption Advisory Council and Global Justice Leaders.

The former Public Protector of South Africa and full-time Commissioner in the South African Law Reform Commission was one of the 11 technical experts who helped draft the South African Constitution, and is a co-architect of several constitutionally mandated laws, including the Equality Act, Employment Equity Act, and the Promotion of Administrative Justice Act. She has an extensive background in applied constitutional, social justice, and administrative law principles, mainly based on her years of public service and her investigation of improper conduct in state affairs as Public Protector. A regular sought-after keynote speaker, Prof Madonsela has written, taught, presented papers, and published on these matters and ethical leadership, good governance, and gender mainstreaming for decades.

Prof Madonsela helped draft several international human rights instruments at UN, AU, and SADC levels, as well as country reports on such matters. She currently teaches Constitutional Law, Social Justice Law, Administrative Law, and Constitutional Governance and Ethical Leadership. She holds eight honorary law doctorates, in addition to two law degrees, a Harvard Advanced Leadership Certificate, and other postgraduate qualifications.

Named one of Time’s 100 most influential people in the world in 2014, Prof Madonsela’s global recognition includes more than 70 awards, including Rotary’s Paul Harris award, the Commonwealth Lawyers Truth and Justice award, and the global ACFE’s Cressy award. Prof Madonsela is a mother of two, a philanthropist, and an avid mountaineer who has summited Mt Kilimanjaro twice under the #Trek4Mandela-#Caring4Girls anti-period poverty campaign and the Musa Plan for Social Justice, and regularly hikes for the #Action4Inclusion campaign, a quest to end student debt.

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.
