Dr Refilwe Mogale
Dr Refilwe Mogale received her PhD in Chemistry. She is fascinated by the ability of chemistry and science in general to solve some of the world’s most pressing issues, such as water scarcity.

“Chemistry chose me,” says Dr Refilwe Mogale, who wanted to enrol for Psychology years ago when she decided to study at the University of the Free State (UFS). 

“On the day of registration, however, as I was standing in the queue, something inside me said this was not the right choice for me. Ultimately, I chose my second option, which was a BSc degree majoring in biology, physics, and chemistry.”

“Once I started the BSc programme, I gravitated towards chemistry, and as difficult as it was juggling classes and six-hour practical sessions, I loved it. I am fascinated by the ability of chemistry and science in general to solve some of the world’s most pressing issues, such as water scarcity, alternative generation, access to antibacterial hygiene products, as well as novel strategies to cure diseases, among many other things.”

The UFS awarded Dr Mogale a PhD in Chemistry on 9 December 2022.

Addressing a global challenge

Being passionate about applied chemistry – where scientific research can be used to create products to address everyday problems – Dr Mogale focused her thesis on Aluminium- and Zirconium-based metal organic frameworks with azobenzene and stilbene dicarboxylate ligands for use in wastewater treatment. 

She has also published multiple articles on topics of environmental chemistry and wastewater management in international journals. 

Dr Mogale is of the opinion that water pollution by financially lucrative industries and access to clean drinkable water is one of our planet’s most challenging environmental and health issues. “The waste generated by some of the industries that contribute heavily to our country’s economy, such as the textile, agricultural, and medical industries, may end up in the limited drinking water resources we have. I chose my research topic because I wanted to positively contribute to this global challenge,” she says.

“My research was based on making highly porous metal-organic frameworks (MOF) to be used in the wastewater treatment technique called adsorption,” explains Dr Mogale, describing MOFs as “really cool three-dimensional ‘sponges’ that can suck up very high amounts of gases and pollutants, trapping them in their pores. These trapped materials can later be released from the pores to be re-used when MOFs are exposed to certain stimuli.”

She continues, “Low cost and simplicity make this method attractive for industrial use. Considering our current energy crisis, other methods are not ideal, since they require large amounts of energy.” 

Focused on developing highly effective adsorbent for wastewater purification systems, Dr Mogale synthesised a novel MOF with one of the highest adsorption capacities compared to existing counterparts.

According to her, should MOFs with their incredibly high surface areas – which allow them to absorb more waste than their existing counterparts – be implemented in wastewater purification systems, they would be able to address the environmental issue of water pollution and the health issue of access to drinkable water.

Tackling everyday societal issues

She is currently doing a postdoctoral fellowship in the UFS Department of Chemistry – to broaden her knowledge in chemistry beyond MOFs. Her plans are, however, to transition to industry and ultimately entrepreneurship, where she will be able to develop scientific products that can tackle everyday societal issues. 

Dr Mogale dreams of adding value to society by practically contributing to the water crisis issue through the development of low-cost water generation and purification products.

Student Bursary Fund Campaign launched: #FundAFuture and make a difference
Motho ke motho ka batho. A person is a person through others

 

We live in a world filled with want. Often, we ache to make a difference, but become overwhelmed and despondent when we look into this chasm of need. However, the University of the Free State (UFS) has created a way for each of us to change lives, in much the same way that the life of Nozi Bonje has been changed.

“Through the opportunities given to me, I realised that you don’t have to be defined by the school you went to. You can do so much more – and you can dream big dreams and realise them.”

Then
The early chapters of Nozi’s life story reveal a shy girl, hiding between the pages of her books on the playground of a township school. With barely a whisper, Nozi was slipping into a desolate future where dreams existed only in sleep.

Now

Today, that timid young girl has grown into a woman who throws her head back in effortless laughter, confidence sparking off her in bright arcs. What changed the trajectory of her future? Financial support for a tertiary education altered Nozi’s life permanently.

“If I didn’t go to university, I would have been this sad little person,” she remarks. “Studying is not just about learning from a textbook, though. It also challenges you to think critically. You start seeing things in a different perspective, and respond differently.”

Giving back
Funding enabled Nozi to obtain a BSc degree in Human Molecular Biology at the UFS in 2015. She was one of the top students in her class. Inspired and driven, she is currently pursuing an honours degree in Molecular Genetics, also at the UFS.

“My main dream is to make a difference in people’s lives. For me, it’s all about giving back, because so many people helped me throughout my journey.”

Student Bursary Fund Campaign

In order to help increase the number of lives transformed through higher education – such as Nozi’s – the UFS has established the Student Bursary Fund Campaign. This campaign aims to raise money to fund talented, deserving students who lack the financial means of obtaining a university degree. We cannot do this alone, though.

Your support is crucial.

Each contribution will bring us closer to our goal while changing the future of our youth. Visit our Giving page for ways to donate.
