UFS official opening
Kovsies is on track with the firm foundation laid in previous years. 2020 is a year where visibility and impact is the key theme.

WATCH: Official Opening 2020

Tackling 2020 with rigour and vigour is the top priority for the University of the Free State’s agenda and it’s all systems go after a year of building a solid foundation. Prof Francis Petersen, UFS Rector and Vice-Chancellor, addressed staff in his official Opening speech at the Bloemfontein Campus on Friday 7 February 2020.

“The university is on track with what it set out to deliver in 2019” Prof Petersen shared the successes of 2019 with the audience and outlined his vision and plans for 2020 with visibility and impact as the key themes. 

Prof Petersen urged staff to work hand-in-hand to ensure an outcome that generations will inherit with pride. “We have our eyes firmly set on the far horizon, to ensure that we bestow an institution on the next generation that is different from the past, a place where every essence is in perpetual renewal. That means every one of us is smaller than the institution, and every one of us needs to lay a brick that builds a university that is different from the past, more impressive than the past, an institution that will grow constantly.” 

Setting the pace

As a frame of reference, Prof Petersen pointed to engagement, conversation, clear communication and decisive action to yield the type of environment in which we all want to work and study. “I can assure you that we will continue with that engagement, in a sphere of respect, tolerance for different views by always focusing on what the Integrated Transformation Plan (ITP) stands for – which is fairness and social justice.”

Reflecting on the year that was.


Prof Petersen reflected on 2019 as a year which focused on a return on investment delivery as it relates to the Strategic Plan, ITP, seven Vice-Chancellor’s projects, institutional and multi-stakeholder group and institutional Risk Register. These guiding documents laid a firm foundation for implementation processes to take place this year.

Leading the way

The Rector related some success stories which include the increased number of NRF-rated researchers. “In the area of student success, we are probably leading the country and our inputs are globally known.”

As a national leader on the infrastructural and student accommodation front, the Department of Higher Education, Science and Technology often consults the UFS for advice on how other institutions can adequately spend their infrastructure grants. Moving forward, the university also plans to partner more with national and international institutions of higher learning with the aim of strengthening research and innovation ties.

On inclusiveness and social cohesion

Pressing issues such as gender-based violence and xenophobia are constantly being tackled by the Unit for Institutional Change and Social Justice in collaboration with other academic and support services. These parties have conducted and developed critical conversations, position papers, and policies to guide the institution towards an inclusive and socially cohesive space which embraces the values of ubuntu and respect.

In closing, Prof Petersen reminded the university community of the crucial role each individual plays in building a bright future. “We must always remember that the UFS exists through its staff and students and should never let one of them feel neglected or unheard.”

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
