Tebogo Motsei
Tebogo Motsei, a PhD student in Physics at the UFS, has been awarded the prestigious CV Raman International Fellowship for African Researchers.

Imagine a supercapacitor/battery made right here in South Africa that could change the way we store energy for the better. A product that can store energy in real time, thus solving energy problems as they happen, which makes a huge difference especially during power outages. A product that is not just good for the environment – transitioning away from lithium-ion batteries – but that can also create jobs and boost the local economy.

What we are talking about is a type of technology known as a sodium-ion supercapacitor/battery, which is the focus of Tebogo Motsei’s research. This technology serves as a power source for lighting, power plants, cars, and phones. Motsei, a PhD student in the Department of Physics on the Qwaqwa Campus of the University of the Free State (UFS), explains that – unlike lithium batteries, which have undergone extensive research and are expensive to produce – they are conducting experimental work and characterisations to determine if sodium-ion supercapacitor/batteries can perform as well or even better, using more affordable and eco-friendly materials.

“Our results, inspired by the urgent need for improved energy storage solutions in South Africa amid its energy challenges, have been very promising. We have successfully developed a sodium-ion supercapacitor/battery that stores as much energy as a lithium-ion battery. Moreover, it was crafted from recycled materials, making it a more cost-effective and environmentally friendly option,” states Motsei, adding that their battery is unique, as no one else in the world has created anything quite like it, despite numerous attempts.

She is also pleased with this supercapacitor/battery’s ability to repair itself. Motsei explains, “Imagine if your toy could fix itself whenever it got broken – that's kind of what our sodium-ion supercapacitor/battery does!”

Motsei is part of a group of scientists in the Department of Physics at the UFS who are working on this research and who have published a scientific article on their work, titled Composite super-capacitor/Na-ion battery with self-healing Fe–Cr alloy electrodes. 

“We're proud of what we have accomplished,” she remarks.

Fellowship: a dream come true

Being part of this impactful research contributed to Motsei receiving the prestigious CV Raman International Fellowship for African Researchers (2023). The fellowship is for African researchers engaged in research at an African institution, providing opportunities for research collaboration in India. Motsei will be the only candidate from South Africa.

This award is merit-based. Motsei attributes her selection to factors such as her strong academic record, research accomplishments, and innovative approach to solving complex problems. She also believes her experience in research, collaboration, and publication reflects her potential to make meaningful contributions to the field during the fellowship period. 

Another key factor contributing to her selection for this fellowship is her skill in fabricating actual devices/prototypes. “The hands-on nature of this research, allowing me to create devices from scratch, has always been my passion. Making my first device – the ‘Magnetron Sputtering Unit’ – during my master’s studies, was a turning point. It made me realise that I had made the best decision ever by choosing this research field. I'm truly passionate about my work,” says Motsei. 

For her PhD studies, she is supervised by Prof Richard Ocaya, Associate Professor in the Department of Physics, and co-supervised by Dr Kamohelo Tshabalala, Senior Lecturer in the Department of Physics. Prof Ocaya, proud of Motsei’s achievements, believes that this fellowship not only serves as a great motivation for students – especially on the Qwaqwa Campus – but also highlights the global relevance of the UFS, particularly the Department of Physics.

Motsei says receiving this fellowship is a dream come true and a profound, life-changing moment for her. “I feel deeply honoured to be concluding this programme at the CSIR-Electrochemical Research Institute, the host institution in India, under the guidance of Prof Arul Manuel Stephan, whose invaluable assistance has been instrumental in my preparations.” Motsei also expressed her gratitude towards everyone who has supported her during this process, including Sudhir Kumar from the Indian Embassy in Pretoria.

“I am excited about how I can use this opportunity to make a difference. Whether it’s tackling significant global energy issues or finding new ways to solve everyday problems, I know this fellowship will give me the tools and support needed to make a real impact. Overall, I see this fellowship as a stepping stone to exciting new opportunities and adventures in the world of research,” she comments.

Making a meaningful impact

Motsei will be leaving for India on 23 February for a period of six months. She is excited about this new chapter in her research journey. “This fellowship will enhance my abilities as a scientist and leader in physics, providing me with essential skills, connections, and experience to make a meaningful impact in science and energy. I'm genuinely happy about this opportunity, which I thank God for.”

  • Sir Chandrasekhara Venkata Raman, after whom the fellowship is named, was a renowned Indian physicist who made great contributions to physics, winning many prizes and awards, including the 1930 Nobel Prize in Physics. He was known for his work in the field of light scattering and was the first Asian and non-European to receive a Nobel prize in any branch of science.

Prof. Barry Rider, respected amongst others for the vital role he is playing in the struggle to combat money laundering and organised and economic crime delivered a lecture, Stewardship in Islamic Financial Law, at our university as part of the Faculty of Law’s Prestige Series of seminars.

He has taught mainly at Cambridge and London Universities and has delivered a valuable contribution as an academic in various fields of law. He has read papers and taught at more than 300 universities and conferences in more than 63 countries. He has also authored more than 35 legal handbooks and has made a substantial contribution to several more specialist publications. He is editor of, amongst others, The Company Lawyer, the International and Comparative Corporate Law Journal and the Journal of Financial Crime. His main areas of research are in financial law and the control of economic crime.
 
Prof. Rider has a relationship of more than twenty years with our university. In this time, he received the Doctor Legum (honoris causa) for his involvement with the drafting of money laundering and insider trading legislation. The university has also appointed him as Professor Honorarius in the Faculty of Law (only the second in its more than hundred-year history) for his vast and pivotal role in international law reform as an academic law reformer.
 
As part of his appointment as Honorary Professor in the Faculty of Law, Prof. Rider often delivers lectures in the faculty. During his recent visit, Prof. Rider’s lecture on Islamic Financial Law shed light on the importance of this topic in today’s economy, as money generated from Islamic businesses make up $750 billion to $trillion of the world’s economy. After 9/11, the West wanted to understand more about Islamic Financial Law.
 
The Islamic Financial Law system is determined by the Koran. For instance, Muslim business people cannot allow any payment of interest, as it is forbidden by the Koran.
 
Prof. Rider’s lecture on this very relevant topic was very insightful. As consultant to the Islamic Financial Services Board (IFSB) he spoke with authority on the topic. He is the only British academic lawyer assisting this body.
 
Prof. Rider currently serves in an advisory capacity at the international law firm Bryan Cave LLP. Apart from the IFSB, he is also consultant to the Asian Development Bank.
