Prof Pearl Sithole, Campus Vice-Principal: Qwaqwa Campus


An increase in post- and undergraduate qualifications, including ten doctoral and seven Master of Science qualifications, for graduates on the Qwaqwa Campus. These were some of the achievements celebrated on the second day of the UFS virtual graduation ceremonies hosted from 6 to 9 October 2020, with students from the Qwaqwa Campus receiving their qualifications. 

Highlighting graduates’ accomplishments, the Rector and Vice-Chancellor, Prof Francis Petersen, said the Qwaqwa Campus had an impressive milestone to celebrate – the significant increase in the number of undergraduate and postgraduate qualifications obtained in 2019. "This includes ten doctoral degrees. This is indeed a remarkable milestone for the campus, well done!"

The campus awarded qualifications to students in the Faculties of Economic and Management Sciences, the Humanities, Education, and Natural and Agricultural Sciences. The Faculties of Education and Natural and Agricultural Sciences had the highest number of postgraduate qualifications, 62 and 43 degrees respectively. 

Boasting a record number of 10 PhD qualifications, the Faculty of Natural and Agricultural Sciences had even more reason to celebrate, producing seven Master of Science graduates. Of the seven MSc students, five were women.
Celebrating these achievements, Prof Aliza le Roux, Assistant Dean of the Faculty of Natural and Agricultural Sciences, said as the first female assistant dean of the faculty, she is impressed with the large number of women graduating with postgraduate degrees. "I am extremely proud of our Faculty of Natural and Agricultural Sciences in Qwaqwa, because our science students are succeeding at some of the hardest degrees you can get. I love working on the Qwaqwa Campus, as the students here give me such hope for the future of science in South Africa," Prof Le Roux said.

One such student is Portia Mosolloane, who obtained her MSc degree in Zoology cum laude. Her dissertation is titled: Rapid detection of escherichia coli in treated and untreated wastewater and the impact of wastewater on riparian macroinvertebrate assemblages.

The following students received their honours and master’s degrees cum laude:

Mmabatho Sebusi – Bachelor of Education Honours with specialisation in Curriculum Studies. 
Matsubela Chakela – Bachelor of Education with specialisation in Management and Governance. 
Unathi Gwama – Bachelor of Education with specialisation in Management and Governance. 
Bongani Msibi – Bachelor of Education with specialisation in Management and Governance. 
Portia Mosolloane – Master of Science in Zoology
Dorah Muthee – Master of Science in Physics.


Virtual Graduation ceremony – Day 1

UFS celebrates the achievements of its newest alumni

"Perhaps this is not the graduation day you envisaged; however, like all graduations, it is a celebratory event that marks the culmination of much hard work, dedication, and commitment to the realisation of your dreams. Graduations are joyous events, occasions of celebration and achievement."

With these words, the Rector and Vice-Chancellor of the University of Free State, Prof Francis Petersen, opened the first in the series of virtual graduation ceremonies taking place this week.
As a highlight on the university's calendar, 6 497 students from the three UFS campuses will be virtually awarded undergraduate and postgraduate qualifications over a period of four days as an alternative to the traditional ceremonies, due to COVID-19 restrictions.

Prof Petersen said the virtual ceremonies did not erase the magnitude of the occasion. "This virtual graduation ceremony is about celebrating your success and achievements. A lot of sacrifices have been made for you to be able to graduate – whether financial, emotional, or in any other way."

Prof Petersen said that, along with the qualifications received, he hoped the graduates would leave the University of the Free State filled with values that would shape their journey as they entered the world of work and society as professionals – the values of critical inquiry, social responsiveness, and integrity.
"When we send out graduates from the University of the Free State, we would like to believe that we send out graduates with impeccable integrity who can make a massive difference in society."

His words were echoed by the university's new Chancellor, Prof Bonang Mohale, who began his term of office in June. Prof Mohale implored graduates to draw and build from their own humanity for the growth and development of all society, to work for a cause, and to make their presence felt in the world.

"To our newest alumni, congratulations. You have earned your academic qualifications, grown intellectually, and accomplished much more than when you first began your studies.”

“Through today's graduation, may I kindly implore all of us to rededicate ourselves to the unfinished task of attaining social justice, defending democracy, and being change agents," Prof Mohale said. 

Making the most of an unprecedented ceremony, scores of people took to the university's YouTube channel to identify and congratulate their loved ones and to celebrate their achievements.

The following students received the Dean's Medal in the various faculties:

Faculty of Economic and Management Sciences:
Jan Johannes van Niekerk – Bachelor of Accounting
Pierré Ludwig Koekemoer – Bachelor of Commerce Honours with specialisation in Marketing

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.
