Ntebohiseng Sekhele hopes her PhD study will address conservation conflicts that exist between communities and protected areas.
The University of the Free State’s Afromontane Research Unit (ARU) based on the Qwaqwa Campus has recently concluded the process of recruiting candidates for the University Capacity Development Programme (UCDP). Through this programme, two historically disadvantaged South African universities; Universities of the Free State (Qwaqwa Campus) and Venda (UNIVEN) and three universities in the United States will be collaborating on a number of PhD research projects.

“The programme is funded through the US-SA Higher Education Network and will give candidates and their supervisors the opportunity to regularly travel to the USA and spend time at participating US universities where their co-promoters will be based and allow them to collaborate with identified suitable academics based at those institutions,” said Prof Geofrey Mukwada, Associate Professor in Geography and the coordinator of the project.

One of the young academics selected for this is Ntebohiseng Sekhele from the Geography Department. She will be doing her research in collaboration with the Colorado State University.

“I am delighted to be part of this programme and it still feels like a dream. I feel honored to be selected to participate in such a prestigious programme. To be chosen amongst other applicants means the coordinators believe in my potential, and I look forward to working towards my full potential,” said Sekhele, who describes herself as ‘a simple and ambitious village girl from Monontsha in Qwaqwa.’ 

Sekhele’s proposed PhD study will focus on determining strategies and impacts of conservation practices by the local communities. “It will address conservation conflicts that exist between communities and protected areas; different interpretations of sustainability (including indigenous knowledge) and offer recommendations of harmonising the conservation practices with the sustainability of conservation areas. There is a great need to develop management strategies that will simultaneously satisfy conservation and human needs. She will be graduating with an MSc (Environmental Geography) degree in 2019.

Other US universities involved in the UCDP are Appalachian State University (ASU) and University of Montana (UoM).

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.
