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.

Through her profound insight, vast experience, and unfaltering belief in humanity, Prof Pumla Gobodo-Madikizela, has secured a R10 million grant from one of the world’s most prestigious foundations funding human sciences research.

“This is one of the biggest grants that the Andrew W. Mellon Foundation has awarded to a university”, said Dr Saleem Badat, Program Director: International Higher Education and Strategic Projects at the Mellon Foundation. Prof Badat attended the press event that took place on 16 February 2015 on our Bloemfontein Campus.

UFS Trauma, Forgiveness, and Reconciliation Studies, spearheaded by Prof Gobodo-Madikizela, will manage the research project.

Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, expressed great excitement “about this particular grant and the subject on which it focuses is so incredibly timely and germane to our own situation.”

Trauma, Memory and Representations of the Past: Transforming Scholarship in the Humanities and Arts

This new-found partnership between the Mellon Foundation and the UFS will enable a five-year research programme. The focus area of this initiative will be ‘Trauma, Memory and Representations of the Past: Transforming Scholarship in the Humanities and Arts’.

The research will pivot specifically around the question of how trauma is transmitted from one generation to the next. “South Africa lends itself to these questions,” Prof Gobodo-Madikizela said, “because we are now dealing with a generation of young people who were born after the traumas of the past.” These past experiences, though, are “passed on to the younger generation and become their own stories and narratives as if they themselves experienced the traumas directly.”

“This is an investment in how we can in fact create a different kind of community,” Prof Jansen said, “in which we eventually recognise each other – not by the accident of our skin, but by that elusive sense of a common humanity.”

Arts and theatre

Other aspects critical to this study are the inclusion of the arts and theatre. Many people have great difficulty in expressing their experiences of trauma in the spoken word. The arts and theatre provide an ideal platform to engage the public and stimulate conversation. As an example of the power these platforms possess, Prof Gobodo-Madikizela highlighted the success of the Johannes Stegmann Art Gallery – situated on the Bloemfontein Campus and curated by Angela de Jesus – in engaging the public in very productive ways.

Participants

Some of the artists, directors and scholars who will join in this project include:

• Lara Foot-Newton, Director/Playwright
• Sue Williamson, Activist Artist
• Angela de Jesus, Visual Artist/Curator
• Dr Buhle Zuma, Social Psychology Research
• Dr Shose Khessi, Social Psychology Research
• Prof Tamara Shefer, Women’s and Gender Studies
• Prof Kopano Ratele, Gender/Men and Masculinities
• Prof Jan Coetzee, Sociology of Developing Societies
• Prof Helene Strauss, Literary and Cultural Studies

New intellectual frontiers

“There is an aspiration in this proposal,” Dr Saleem Badat said. “We were born through this pain of colonialism and apartheid; we even went through the TRC. Our scholars in this country, our universities, should be at the forefront of this research. This is not research we can leave to the institutions in the north.”

Prof Gobodo-Madikizela agreed. “The overarching theme of this work is new knowledge production, focusing on the experiences in South Africa as experiences that can teach us something new.”

This will serve not only South Africa, but can also establish support for, and inform, countries facing similar dilemmas. In fact, “any part of the world in which genocide and murder and racism remains as legacies from the past,” Dr Badat said.
