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.

UFS institute set to contribute to transformation in South Africa

Today (Thursday, 27 January 2011), almost three years after the Reitz affair, the University of the Free State (UFS) is launching its International Institute for Studies in Race, Reconciliation and Social Justice. This international institute will be inaugurated by Archbishop Emeritus Desmond Tutu, Nobel Peace Prize Laureate and Chairperson of the former Truth and Reconciliation Commission, who received an honorary doctorate in Theology from the university earlier today.

According to Mr John Samuel, Interim Director of the institute and former Chief Executive Officer of the Nelson Mandela Foundation, the institute seeks to establish itself as a premier international site for research on race, reconciliation and social justice.

“It is encouraging to see the UFS bringing to the fore such an initiative, which combines a study in race, reconciliation and social justice, all of which are indispensible elements in the process of rebuilding our nation,” said the Deputy President of South Africa, Mr Kgalema Motlanthe, in his message of congratulations to the university.

“I am confident that on the strength of its stature, coupled with its eminent experience as an academic institution, the UFS will further assist our country advance towards a united, non-racial, non-sexism, just and prosperous future.

“I wish the institute well in its arduous but noble task of contributing to the building of a better human society,” he said.

Prof. Jonathan Jansen, Vice-Chancellor and Rector, stated during his official inauguration in 2009 that the university would be an example of a place where reconciliation, forgiveness and social justice would not only be studied, but where it would also be applied in practice. “Students and scholars from across the world will come to the UFS to study the theory and practice about the building of societies across the boundaries of race, as well as religion, gender, disabilities and national origin,” Prof. Jansen said.

The institute is a critical space where engaged scholarship, public discussion, community engagement and teaching are innovatively integrated towards exploring and finding solutions to the complex and challenging work of social transformation in South Africa.

The institute furthermore works towards the realisation of its mission through a multiplicity of approaches and methods, informed by the notion that deep and complex social challenges require courageous and challenging scholarship, supported by innovative organisational forms and institutional arrangements.

Working from the inside to the outside, the institute will firstly serve the needs of the university, its staff and students. Through its research, the institute will endeavour to understand the challenges facing the UFS better, as well as how to address these challenges. For this reason, the concept of the UFS as a “live laboratory” and the use of evidence-based practice remain important for the university.

The institute will also reach out and empower its stakeholder communities through research and ongoing involvement on issues of race, reconciliation and social justice. Furthermore the institution expects to contribute to the creation of national and international networks and dialogue platforms pertaining to race, reconciliation and social justice.

For the first five years, the themes of 1) Values, Faith and Social Justice; 2) Development and Social Cohesion; 3) Teaching and Learning for Social Justice; and 4) Provincial, National, Global Perspectives and Leadership will direct the institute’s work.

The UFS will make a substantial contribution to the pursuit of reconciliation, greater social cohesion and equity in South Africa. The university is thus prepared to continue to engage the difficult, practical and trying work of building a strong, quality institution as it promotes racial healing and addresses the structural imbalances of the past. It is at this nexus that the institute commits to enabling change at the university as well contributing to transformation in South Africa.
