Young researcher to jet out to UK

When Mamosa Ngcala jets out to the United Kingdom (UK) on 31 July 2018, she will not only be doing research and improving herself academically at the Durham University, but she will also put yet another feather in the growing research profile cap of the Qwaqwa Campus.

“I am looking forward to my study visit under the mentorship of Dr Steve Chivasa, my supervisor’s co-researcher in the Department of Biosciences at the renowned Durham University. This will enable me to grow academically as much as it will get me closer to concluding my research on climate change and food security,” said Mamosa, a master’s student in Science (Botany). Her supervisor is Dr Rudo Ngara.

“Going there will fast-track my research that looks at how food security can be enhanced in as far as growing sorghum is concerned. This study in Plant Biotechnology aims to identify heat responsive genes in sorghum, which is the fifth most important cereal crop in the world. The information obtained in this study will serve as fundamental knowledge regarding molecular responses of plants to heat stress and will be used in breeding programmes to develop crops that can tolerate high temperature stress conditions caused by climate change, thus resulting in high crop yield in agriculture as well as food security,” she said. She will be in the UK until 12 September 2018.

Mamosa has recently won the 3-Minute thesis competition for graduates that was part of the ‘Sorghum in the 21st Century’ international conference held in Cape Town.

Talking about this achievement, she said: “Going head-to-head with PhD students from all over the world gave me extra motivation and drive to do well, and I did. This goes to show that we can achieve whatever we put our minds to. Having to summarise my entire study in three minutes for a non-specialist audience, using one PowerPoint slide, was a challenge that had to be overcome,” said Mamosa. The conference was organised by the Collaborative Research on Sorghum and Millet and the University of Pretoria.

Mamosa graduated with distinction in Botany for her honours degree. She is a member of the Golden Key International Honour Society and Chairperson of the Postgraduate Student Council and is looking forward to advancing her studies to PhD level.

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.
