The University of the Free State Qwaqwa Campus is celebrating a significant boost to its academic and research standing with the recent achievement of National Research Foundation (NRF) ratings by several esteemed academics. These ratings not only recognise the individual accomplishments and impact of these researchers but also underscore the campus' commitment to Vision 130 and the university's overarching strategy for academic and research excellence.

The Deputy Vice-Chancellor: Research and Internationalisation, Prof Vasu Reddy, explained the ratings, saying, “Ratings embody high ideals and recognition of scientific merit and impact in a knowledge-intensive economy, aligned with the UFS’ aspirations.”

Prof Jared McDonald, Assistant Dean of the Faculty of The Humanities, Dr Calvin Mudzingiri, Assistant Dean of the Faculty of Economic and Management Sciences, and Prof Richard Ocaya from the Department of Physics have all been awarded C2 ratings, signifying that they are established researchers with considerable international recognition for the quality and impact of their research outputs. This level of recognition highlights their consistent contribution to their respective fields and positions them as key players within the global research landscape.

Building on this impressive achievement, Prof Aliza le Roux, Assistant Dean of the Faculty of Natural and Agricultural Sciences, has attained a C1 rating, indicating that she is a leading international researcher recognised for the high quality and impact of her recent research outputs. This prestigious rating stresses Prof Le Roux's significant contributions and her standing as a prominent figure in her area of expertise.

Adding to the growing cadre of research talent on the Qwaqwa Campus, Dr Nthatisi Nyembe, Lecturer in the Department of Zoology and Entomology, and Dr Victor Gwande – Senior Lecturer in the Department of History – have both received Y1 ratings. Dr Regret Sunge, Lecturer in the Department of Economics and Finance within the Faculty of Economic and Management Sciences, has received the NRF Y2 rating for the period 1 January 2025 to 31 December 2030. This rating is awarded to promising young researchers who have demonstrated the potential to establish themselves as researchers with strong international recognition within five years after obtaining their doctorates. These Y1 ratings signal a bright future for research on the campus, highlighting the emergence of a new generation of impactful scholars.

NRF ratings are a crucial benchmark within the South African academic and research sector. They provide a peer-review assessment of the quality and impact of researchers' work, lending credibility and prestige to both the individual and their institution. For academics, a strong NRF rating can enhance their research collaborations, funding opportunities, and overall academic standing. For the institution, a growing number of rated researchers reflects a vibrant research environment and contributes to its reputation as a leading centre of knowledge production.

These achievements align directly with the UFS' Vision 130, which aims to elevate the university's academic and research profile, fostering a culture of innovation and impactful scholarship. The success of these Qwaqwa Campus academics demonstrates the tangible progress being made towards realising this vision and strengthening the university's strategic goals in academic and research excellence.

The UFS is committed to nurturing and supporting its academics in their research endeavours. Initiatives such as the Future Professoriate Programme and the Emerging Scholars Advancement Programme (ESAP) play a vital role in providing mentorship, resources, and opportunities for academics to develop their research careers and achieve their full potential. The recent NRF ratings are a testament to the effectiveness of these support structures and the dedication of the academics on the Qwaqwa Campus.

The University of the Free State proudly celebrates the accomplishments of Prof McDonald, Dr Mudzingiri, Prof Ocaya, Prof Le Roux, Dr Nyembe, Dr Gwande, and Regret Sunge. Their success is a source of inspiration for the entire university community and reaffirms the Qwaqwa Campus' growing prominence as a hub of impactful research.

In his congratulatory remarks, Prof Reddy said: “Our colleagues’ ratings confirm their dedicated and sterling work in advancing research and innovation. It is commendable to also see academic leaders in professional support being beacons to inspire others.”

He further commented: “We value your hard work and determination. Congratulations, you make us proud as a university. You inspire us all to follow you and we support you in reaching our research-intensive goals. We are confident that your ratings will inspire you, personally and professionally – as well as other colleagues – to grow further. Your efforts will help us as we move to new heights,” Prof Reddy concluded.

Lithium-ion batteries research set to improve ordinary lives
2016-02-11

Description: Dr Lehlohonolo Koao  Tags: Dr Lehlohonolo Koao

Dr Koao is making a much-needed contribution in improving lives of ordinary people through his research on lithium-ion batteries.

The future of relevant and top-notch scientific research at the Qwaqwa Campus is in good hands. Dr Lehlohonolo Koao is one of the five members of the Vice-Chancellor’s Prestige Scholars Programme (PSP) on the Qwaqwa Campus.

The need to improve the efficiency of heating mechanisms in his immediate community in Qwaqwa, and the support he receives from the PSP, have become catalysts for his current research project on lithium-ion batteries. According to Dr Koao, the study will focus on producing batteries that last longer, store more energy, are cheaper to manufacture, and are environmentally friendly when being disposed of. These are key factors in solar energy.

‘’The majority of households in my neighbourhood have benefited from the government’s project of providing households with solar panels to help with lighting, cooking, and heating without worrying about the ever-increasing electricity costs,’’ said Dr Koao.

‘’Since my arrival in the area, I have realized that the heat absorption rate of the batteries used by solar panels is not enough. As a result, these batteries also lack enough power to sustain the supply throughout the day, especially on a cloudy day,’’ he said.

His research project focuses on improving the efficiency of lithium-ion batteries that are now commonly used in portable electronics, such as cell phones and laptops. This kind of battery is rapidly replacing the usual lead-acid batteries. Dr Koao’s determination to contribute towards a safer and more efficient heating absorption system has made him move away completely from his PhD study on lighting material.

‘’My previous study was on reducing the power usage on domestic and industrial lights as they use more electricity. This study, on the other hand, will enhance power retention in the batteries for improved daily life since cell phones, solar panels, and laptops, to mention only a few, are now a way of life,’’ he added.

Dr Koao is a Senior Lecturer in the Department of Physics, where he specializes in solid state materials.
