Abe Bailey Bursary victor
“I believe in self learning,” says 2018 UFS Abe Bailey victor, Nkahiseng Ralepeli.
The Abe Bailey Trust is a leadership-development opportunity that targets university students or junior lecturers who are academically strong and have shown exceptional qualities of leadership and service. Recipients of the bursary are required to have a good record of accomplishments, not only on campus but also in a broader social context, where they function as an integral piece of a select and highly-skilled group of individuals.

Ralepeli, the over-achiever

Final-year Law student, Nkahiseng Ralepeli, embodies this exact description and exemplifies the essence of distinction and merit when it comes to who he is. Ralepeli  who has represented the university at various international debate platforms, an alumni of the F1 programme to Thailand and other leadership programmes such, recently, International Youth Leadership Conference (IYLC) programme in Prague, will represent the University of the Free State (UFS) during the Abe Bailey Travel Bursary tour in the UK in December 2018. He, along with 16 other candidates from other South African tertiary institutions, will participate in the tour for its full duration and will take part in the exciting developmental programme that is planned.

With an intense but fruitful leadership-training schedule, he said he was looking forward to meeting the British members of parliament as well as other persons of stature in the British government.

Travelling: A catalyst for critical thinking

Ralepeli, who was also 3rd overall Kovsie Dux student, underlined that he truly enjoys travelling. He has subsequently mastered the art of constantly positioning himself among the best academically and socially, and this has aided his mission to trot the globe extensively, which he has been doing since his junior years.

A man of value

“I have a small yet select and impactful network of people in my life who play an influential role in reminding me during times of triumph that, while it is important to celebrate, each win is just a step towards the ultimate goal of success,” said Ralepeli. 

He emphasised the importance of the roles played by those close to him, describing them as “my double-edged sword who played a crucial role in carving out the inner Nkahiseng, who, hopefully, will do great things”. The Kovsie Dux believes that those you surround yourself with, channel the kind of energy that will either make or break you.

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.
