The University of the Free State (UFS) recently had the honour of hosting a thought-provoking guest lecture delivered by His Excellency Dr Reuben E Brigety II, the United States Ambassador to South Africa. Held on 23 April 2024 at the Centenary Complex, on the UFS Bloemfontein campus, the lecture delved into the vital role of higher education in fostering and safeguarding democracies.

Describing the occasion as a pivotal moment for the institution, Prof Francis Petersen, Vice-Chancellor and Principal of the UFS, articulated, "Having the United States Ambassador to South Africa visit our institution and deliver this guest lecture presents an invaluable opportunity. It allows us to gain unique insights into the parallel dynamics and challenges facing our sister democracies, particularly as both our countries approach significant electoral periods.”

Dr Brigety, in his address, underscored the significance of higher education in the context of Freedom Day, celebrated in South Africa on 27 April 2024. He emphasised the role universities play in advancing democratic values, drawing upon the UFS motto, “In truth is the light of wisdom” to elucidate this connection. Highlighting the inspirational figure of the late Charlotte Maxeke, a prominent social and political activist, Dr Brigety noted her pivotal role in both South African and American contexts.

Maxeke, a graduate of Wilberforce University, and her husband Marshall Maxeke, founded the Wilberforce Community College upon returning to South Africa. Dr Brigety underscored the significance of Maxeke’s commitment to civil liberties and education, along with her enduring ties to the Wilberforce University network, in shaping subsequent generations of activists and leaders.

Moreover, Dr Brigety stressed the importance of collaborative efforts between South African and American universities amidst today’s complex global challenges. He advocated for initiatives such as collaborative research projects, joint academic programmes, and student exchanges, citing their role not only in knowledge creation but also in fostering mutual understanding and strengthening bilateral relations.

In concluding his address, Dr Brigety urged the audience to emulate the examples set by individuals like Charlotte Maxeke and Prof Jonathan Jansen, the former Rector and Vice-Chancellor of UFS. He encouraged them to champion the cultivation of the next generation of leaders, thinkers, and change-makers.

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.
