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.

B. Iur. programme in Occupational Risk Law first of its kind in the country
2010-11-26

The University of the Free State (UFS) will offer a B.Iur. degree programme in Occupational Risk Law from 2011.

This programme of the Faculty of Law is the first of its kind to be offered in South Africa and positions the UFS in the forefront of this field of study.

The programme is designed to develop and qualify professionals, knowledgeable in the field of occupational risk law as prescribed by South African legislation and international best practices. It further offers a qualification based on a well-researched basis of applicable legal principles, combined with safety, health, environmental and quality risk management principles applicable to employers and employees in a specialised industry.

The B.Iur. (Occupational Risk Law) has been developed by experts within the parameters of international comparability, according to research-based identification of career demands and requirements in the fields mentioned.

By introducing this programmesignificant progress will be made towards achieving the nationally stated objective of legal safety, health and environmental quality assurance in the workplace and within the broader community. The programme will also encompass the values and standards prescribed by the Institute of Safety Managers. This will provide them with a further step towards the regulation of the professional en ethical standards in the field of legal safety, health and environmental quality assurance.

With the programme, the UFS not only creates a unique opportunity for stakeholders and learners to add meaningful value to their careers, but also exerts a meaningful influence on the industry and society in terms of the acquisition of a most appropriate type of qualification. The B.Iur. (Occupational Risk Law)degree therefore offers a meaningful contribution towards the industry through addressing the increasing demand for career opportunities in the field of legal safety, health and environmental quality compliance.

The new programme is the result of an agreement between the faculty and its partner, IRCA Global. The university officially launched its partnership with IRCA Global, an international supplier of risk management solutions pertaining to safety, health, the environment and quality in 2008. As part of the agreement, the UFS will offer short learning programme, a diploma and a degree in Risk Management.

IRCA Global is a South African company in the international risk control and SHEQ environments with filials in Africa, Australia, India, Eastern Europe, and South America.

In the interim IRCA Global has continued with the marketing of the programme, with the result that hundreds of potential students are waiting for the launching of the programme. The faculty is geared towards offering the programme in e-learning. New modules will also be offered with the help of IRCA’s trained and skilled facilitators. The faculty also utilises the partnerships entered into with IRCA to appoint practising specialists as part-time lecturers for the occupational risk law component of the programme as well as to develop a new specialist component amongst the permanent staff.

The programme is already active and students can register for the first semester 2011 (study code 3324, programme code M3000). Direct your enquiries to Cora-Mari de Vos at 051 401 3532 or devosc@ufs.ac.za.

The programme consists of fundamental modules of the LL.B. and B.Iur., as well as short learning programmes in the Faculty of Law and specially developed core modules in occupational risk law. The B.Iur.in Occupational Risk Law enables successful candidates to enrol for applicable Post Graduate Diplomas or a cognate Honours Degree. Obtaining one of these qualifications provides the platform to articulate to Magister degrees. Horizontal articulation possibilities exist with the accredited Baccalaureus of Law (LL.B.) which is presented by several institutions in the country.
