The Council of the University of the Free State (UFS) approved the lifting of the institution’s COVID-19 Regulations and Required Vaccination Policy with immediate effect.

“Since the declaration by the Government on 22 June 2022 that the COVID-19 regulations will be repealed, the UFS has conducted a risk assessment to determine the risk of exposure to staff and students. From the assessment, it was clear that the university’s COVID-19 infections are currently a low risk,” said Prof Francis Petersen, Rector and Vice-Chancellor of the UFS.

Factors that contributed to this low risk include the following:

  • No COVID-19 positive cases among UFS staff and students have been reported in the past month.
  • The high number of vaccinations among UFS stakeholders. In addition, the current national immunity level of the total South African population is high.
  • Certain faculties and postgraduate students are currently proceeding with hybrid/online learning, which minimises the risk of possible COVID-19 infections on the university’s three campuses.
  • In its correspondence of 23 June 2022, the UFS urged all staff and students to continue wearing masks should they have comorbidities and/or symptoms of illness, thus safeguarding other stakeholders.

“We believe that COVID-19 no longer poses an immediate threat to the safety of our staff and students, and that the pandemic is at a stage where they should take responsibility for their own safety. This can be mainly ascribed to the success of the implementation of the policy. Staff and students who still wish to wear masks are urged to do so at their own discretion. Those who have not yet been vaccinated against the virus and have no

known condition preventing them from doing so, are advised to get vaccinated for their own safety and protection,” said Prof Petersen.

The UFS COVID-19 Regulations and Required Vaccination Policy was approved by the University Council on 26 November 2021 and implemented on 6 December 2021. The university commenced restricting unvaccinated individuals from accessing its campuses as of 14 February 2022.

“If the national regulatory environment with respect to COVID-19 is changing to such an extent that the policy needs to be re-implemented, the university’s executive management will act accordingly, and hence the COVID-19 Regulations and Required Vaccination Policy remains a policy of the university as approved by the UFS Council on 26 November 2021.” said Prof Petersen.

NRF grants of millions for Kovsie professors

Two professors received research grants from the National Research Foundation (NRF). The money will be used for the purchase of equipment to add more value to their research and take the university further in specific research fields.

Prof Martin Ntwaeaborwa from the Department of Physics has received a R10 million award, following a successful application to the National Nanotechnology Equipment Programme (NNEP) of the NRF for a high-resolution field emission scanning electron microscope (SEM) with integrated cathodoluminescence (CL) and energy dispersive X-ray spectrometers (EDS).

Prof Bennie Viljoen from the Department of Microbial, Biochemical and Food Biotechnology has also been awarded R1,171 million, following a successful application to the Research Infrastructure Support Programme (RISP) for the purchase of a LECO CHN628 Series Elemental Analyser with a Sulphur add-on module.

Prof Ntwaeaborwa says the SEM-CL-EDS’ state-of-the art equipment combines three different techniques in one and it is capable of analysing a variety of materials ranging from bulk to individual nanoparticles. This combination is the first of its kind in Africa. This equipment is specifically designed for nanotechnology and can analyse particles as small as 5nm in diameter, a scale which the old tungsten SEM at the Centre of Microscopy cannot achieve.

The equipment will be used to simultaneously analyse the shapes and sizes of submicron particles, chemical composition and cathodoluminescence properties of materials. The SEM-CL-EDS is a multi-user facility and it will be used for multi- and interdisciplinary research involving physics, chemistry, materials science, life sciences and geological sciences. It will be housed at the Centre of Microscopy.
“I have no doubt that this equipment is going to give our university a great leap forward in research in the fields of electron microscopy and cathodoluminescence,” Prof Ntwaeaborwa said.

Prof Viljoen says the analyser is used to determine nitrogen, carbon/nitrogen, and carbon/hydrogen/nitrogen in organic matrices. The instrument utilises a combustion technique and provides a result within 4,5 minutes for all the elements being determined. In addition to the above, the machine also offers a sulphur add-on module which provides sulphur analysis for any element combination. The CHN 628 S module is specifically designed to determine the sulphur content in a wide variety of organic materials such as coal and fuel oils, as well as some inorganic materials such as soil, cement and limestone.

The necessity of environmental protection has stimulated the development of various methods, allowing the determination of different pollutants in the natural environment, including methods for determining inorganic nitrogen ions, carbon and sulphur. Many of the methods used so far have proven insufficiently sensitive, selective or inaccurate. The availability of the LECO analyser in a research programme on environmental pollution/ food security will facilitate accurate and rapid quantification of these elements. Ions in water, waste water, air, food products and other complex matrix samples have become a major problem and studies are showing that these pollutants are likely to cause severe declines in native plant communities and eventually food security.

“With the addition of the analyser, we will be able to identify these polluted areas, including air, water and land pollution, in an attempt to enhance food security,” Viljoen said. “Excess levels of nitrogen and phosphorous wreaking havoc on human health and food security, will be investigated.”
