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.

MBA Programme - Question And Answer Sheet - 27 May 2004
2004-05-27

1. WHAT MUST THE UNIVERSITY OF THE FREE STATE (UFS) DO TO GET FULL ACCREDITATION FOR THE MBA PROGRAMMES?

According to the Council on Higher Education’s (CHE) evaluation, the three MBA programmes of the UFS clearly and significantly contribute to students’ knowledge and skills, are relevant for the workplace, are appropriately resourced and have an appropriate internal and external programme environment. These programmes are the MBA General, the MBA in Health Care Management and the MBA in Entrepreneurship.

What the Council on Higher Education did find, was a few technical and administrative issues that need to be addressed.

This is why the three MBA programmes of the UFS received conditional accreditation – which in itself is a major achievement for the UFS’s School of Management, which was only four years old at the time of the evaluation.

The following breakdown gives one a sense of the mostly administrative nature of the conditions that have to be met before full accreditation is granted by the CHE:

a. A formal forum of stakeholders: The UFS is required to establish a more structured, inclusive process of review of its MBA programmes. This is an administrative formality already in process.

b. A work allocation model: According to the CHE this is required to regulate the workload of the teaching staff, particularly as student numbers grow, rather than via standard management processes as currently done.

c. Contractual agreements with part-time staff: The UFS is required to enter into formal agreements with part-time and contractual staff as all agreements are currently done on an informal and claim-basis. This is an administrative formality already in process.

d. A formal curriculum committee: According to the CHE, the School of Management had realised the need for a structure – other than the current Faculty Board - where all MBA lecturers can deliberate on the MBA programmes, and serve as a channel for faculty input, consultation and decision-making.

e. A system of external moderators: This need was already identified by the UFS and the system is to be implemented as early as July 2004.

f. A compulsory research component: The UFS is required to introduce a research component which will include the development of research skills for the business environment. The UFS management identified this need and has approved such a component - it is to take effect from January 2005. This is an insufficient element lacking in virtually all MBA programmes in South Africa.

g. Support programmes for learners having problems with numeracy: The UFS identified this as a need for academic support among some learners and has already developed such a programme which will be implemented from January 2005.

The majority of these conditions have been satisfied already and few remaining steps will take effect soon. It is for this reason that the UFS is confident that its three MBA programmes will soon receive full accreditation.

2. WHAT ACCREDITATION DOES THE UFS HAVE FOR ITS MBA PROGRAMME?

The UFS’s School of Management received conditional accreditation for its three MBA programmes.

Two levels of accreditation are awarded to tertiary institutions for their MBA programmes, namely full accreditation and conditional accreditation. When a programme does not comply with the minimum requirements regarding a small number of criteria, conditional accreditation is given. This can be rectified during the short or medium term.

3. IS THERE ANYTHING WRONG WITH THE ACADEMIC CORE OF THE UFS’s MBA PROGRAMMES?

No. The UFS is proud of its three MBA programmes’ reputation in the market and the positive feedback it receives from graduandi and their employers.

The MBA programmes of the UFS meet most of the minimum requirements of the evaluation process.

In particular, the key element of ‘teaching and learning’, which relates to the curriculum and content of the MBA programmes, is beyond question. In other words, the core of what is being taught in our MBA programmes is sound.

4. IS THE UFS’s MBA A WORTHWHILE QUALIFICATION?

Yes. Earlier this year, the School of Management – young as it is - was rated by employers as the best smaller business school in South Africa. This was based on a survey conducted by the Professional Management Review and reported in the Sunday Times Business Times, of 25 January 2004.

The UFS is committed to maintaining these high standards of quality, not only through compliance with the requirements of the CHE, but also through implementing its own quality assurance measures.

Another way in which we benchmark the quality of our MBA programmes is through the partnerships we have formed with institutions such as the DePaul University in Chicago and Kansas State University, both in the US, as well as the Robert Schuman University in France.

For this reason the UFS appreciates and supports the work of the CHE and welcomes its specific findings regarding the three MBA programmes.

It is understandable that the MBA review has caused some nervousness – not least among current MBA students throughout the country.

However, one principle that the UFS management is committed to is this: preparing all our students for a world of challenge and change. Without any doubt the MBA programme of the UFS is a solid preparation.
