Tennis the bright spark at USSA
The Kovsie Tennis team was crowned as USSA victors for the eighth consecutive time at the recent University Sports South Africa tournament

Even though some Kovsie sport codes came close, it was eventually only the tennis team who were able to grab hold of a gold medal at the various USSA (University Sport South Africa) tournaments taking place in numerous cities across the country during the student winter holidays.

It was the eighth consecutive USSA crown for the Kovsie tennis team. They won all their matches with ease and even the final against Tuks was a one-way affair, winning eight games to one.

The other sport that came close to winning their tournament, was the netball girls. They came unstacked in the final, losing 30-48 to Tuks. It was the first time since 1998 that Kovsies hosted the USSA netball tournament.

The Kovsie female hockey team claimed third spot and the men, playing in the B section, ended second. They only lost once (against the University of KwaZulu-Natal by a single goal), which denied them promotion to the A section.

The Shimlas nearly obtained bronze, but a penalty try for Wits in the closing minutes cost them in the play-off match for 3rd/4th position.

Both the men and women’s football teams ended sixth, but more importantly, the women qualified for the 2019 Varsity football competition. The women improved by two positions and the men by four places from the 2017 tournament.

The table tennis team didn’t have an official final position. They lost in the quarterfinals.

The basketball men ended ninth and the women tenth, improving by ten and six places respectively.

The volleyball men’s team finished in 11th position and the women took 15th spot.

Lithium-ion batteries research set to improve ordinary lives

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.
