The Faculty of Natural and Agricultural Sciences (NAS) at the University of the Free State (UFS) Qwaqwa Campus is celebrating a year of remarkable achievements, showcasing the dedication and brilliance of its students and faculty. The 2024 academic year has been marked by outstanding academic performance, prestigious awards, and groundbreaking research, solidifying the faculty's commitment to excellence.


Academic excellence shines bright

The faculty's commitment to rigorous academic standards has yielded impressive results. This year, four doctoral candidates successfully obtained their PhDs, contributing valuable research to their respective fields. Furthermore, the dedication of the honours and master’s students was evident in their exceptional performance. Out of 25 honours students, an impressive 11 achieved distinctions, demonstrating their mastery of their subjects. Similarly, 5 out of 10 master’s students passed with distinctions, a testament to their advanced research capabilities and academic prowess.


Dr Tebogo Motsei: A beacon of innovation and excellence

Among the faculty's many successes, the achievement of Dr Tebogo Motsei stands out as a testament to the calibre of talent being nurtured on the UFS Qwaqwa Campus. Dr Motsei, who recently graduated from the campus, was awarded the prestigious CV Raman Scholarship by the Government of the Republic of India – a recognition bestowed upon only the most promising postgraduate students.

This highly competitive scholarship, named after the Nobel prize-winning physicist Chandrasekhara Venkata Raman, provided recipients with a six-month research opportunity in India. Dr Motsei conducted her research at the esteemed Central Electrochemical Research Institute (CECRI), under the guidance of Prof Arul Manuel Stephan and Prof Sabu Thomas, Vice-Chancellor of the Mahatma Gandhi University. CECRI – one of the most difficult Indian institutes to get admitted into – is part of the Council for Scientific and Industrial Research (CSIR).

Dr Motsei’s research focused on sodium-ion batteries and supercapacitors with lithium-sulphur integration, resulting in significant advancements in energy storage devices. Her innovative work has the potential to revolutionise the field, contributing to more efficient and sustainable energy solutions.   

Adding to her achievements, Dr Motsei also established Lesedi Innovations Pty, a company dedicated to the manufacturing of button batteries and cells of the CR2032 and 18650 form factors. This entrepreneurial endeavour highlights her commitment to translating research into practical applications that benefit society.

For her PhD studies, she was supervised by Prof Richard Ocaya 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.


A message of pride and congratulations

Prof Aliza le Roux, Assistant Dean of the Faculty of Natural and Agricultural Sciences, expressed her immense pride in the students and staff. "I would like to congratulate the NAS students and staff members on this fantastic achievement – it’s a sign of people going out of their way to do their best and make their research work despite any obstacles thrown in their way. These distinctions show that we have smart, dedicated, creative people in NAS, and I’m very proud of all of them. For students, this means great opportunities ahead, and for staff, it is a sure sign that they did something right in their mentorship and teaching. Thank you to this wonderful team," concluded Prof Le Roux.

The UFS Qwaqwa Campus congratulates all the graduates, distinguished students, and dedicated staff of the Faculty of Natural and Agricultural Sciences. Their accomplishments are a testament to the university's commitment to fostering academic excellence and innovation. The faculty continues to fly the UFS flag high, inspiring future generations of scientists and researchers.

Dr Abdon Atangana cements his research globally by solving fractional calculus problem
2014-12-03

 

Dr Abdon Atangana

To publish 29 papers in respected international journals – and all of that in one year – is no mean feat. Postdoctoral researcher Abdon Atangana at the Institute for Groundwater Studies at the University of the Free State (UFS) reached this mark by October 2014, shortly before his 29th birthday.

His latest paper, ‘Modelling the Advancement of the Impurities and the Melted Oxygen concentration within the Scope of Fractional Calculus’, has been accepted for publication by the International Journal of Non-Linear Mechanics.

In previously-published research he solved a problem in the field of fractional calculus by introducing a fractional derivative called ‘Beta-derivative’ and its anti-derivative called ‘Atangana-Beta integral’, thereby cementing his research in this field.

Dr Atangana, originally from Cameroon, received his PhD in Geohydrology at the UFS in 2013. His research interests include:
• the theory of fractional calculus;
• modelling real world problems with fractional order derivatives;
• applications of fractional calculus;
• analytical methods for partial differential equations;
• analytical methods for ordinary differential equations;
• numerical methods for partial and ordinary differential equations; and
• iterative methods and uncertainties modelling.

Dr Atangana says that, “Applied mathematics can be regarded as the bridge between theory and practice. The use of mathematical tools for solving real world problems is as old as creation itself. As written in the book Genesis ‘And God saw the light, that it was good; and divided the light from the darkness’, the word division appears here as the well-known method of separation of variables, this method is usually employed to solve a class of linear partial differential equations”.

“A mathematical model is a depiction of a system using mathematical concepts and language. The procedure of developing a mathematical model is termed mathematical modelling. Mathematical models are used not only in natural sciences, but also in social sciences such as economics, psychology, sociology and political sciences. These models help to explain systems and to study the effects of different components, and to make predictions about behaviours.”
