Sikhululekile Luwaca named 100 Young Mandelas of the future
Sikhululekile Luwaca was recently named as one of 100 Young Mandelas of the future by News24 for his embodiment of Nelson Mandela’s characteristics.
On Tuesday 3 July 2018, News24.com announced the 100 Young Mandelas of the future. Among those nominated was Sikhululekile Luwaca, a former president of the Student Representative Council (SRC) at the University of the Free State (UFS).
 
“It is humbling. I embrace collective action and it would be unfair not to appreciate all the great minds I have encountered over the years and had the privilege to work with. Our individual progress can never be separated from that of the community. It is no longer I that lives, but us, we,” said Luwaca.

Six million readers nominated 1 000 South Africans from all walks of life who could be considered Mandelas of the future. Luwaca emerged in the Visionary category as one of the 100 who made the cut. The initiative was inspired by what would have been Nelson Mandela’s 100th birthday on 18 July 2018. “News24 set out to honour 100 young South Africans who embody the characteristics Mandela was best known for,” said a statement by News24.

While he was the SRC president, Luwaca’s office played a critical role in raising R1.2 million for underprivileged students. He continues to make major strides as the current chairperson of the UFS African National Congress Youth League (ANCYL). 

His social and political influence goes back to when a 13-year-old Luwaca founded an association that sought to address school dropouts in rural areas. In high school, the young philanthropist established an organisation that collected and distributed food for needy elders of Cathcart township in the Eastern Cape. For five years Luwaca served the Student Christian Organisation as chairperson. In 2013, he co-founded the Ubuntu School Project that donated 100 full school uniforms to Phomolong High School learners in Tembisa.

Later on as a UFS student, Luwaca helped found the Hand2Hand Student Association which drives fundraising initiatives, as well as the collection of non-perishable food items and second-hand textbooks for disadvantaged students. In 2015 he was elected a Residence Committee representative for House Outeniqua and SRC: Dialogue and Association. 

Luwaca was instrumental in facilitating a series of dialogues on transformation such as the Fees Must Fall movement and the Shimla Park incident.

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.
