Students urged to help combat crime
What to do in case of an attack? The UFS taekwondo team taught students a trick or two.
Speaking at the official opening of Safety Week, newly elected Student Representative Council (SRC) president of the Bloemfontein Campus called for students to come to the party in the fight against crime. “We encourage students to participate because it cannot just be the SRC, university management, and the police. Students need to join the Community Police Forum because these platforms are there for us to engage in. You must not die in silence, if there is a problem, raise it,” said Sonwabile Dwaba.

The University of the Free State’s (UFS) Protection Services in collaboration with the university’s BSafe campaign hosted the Safety Week from 3-6 September 2018 on the Bloemfontein and South campuses with the objective of keeping students and staff members informed on the measures in place, addressing pressing safety-related concerns, brainstorm ideas on how to beef up security, and distributing safety souvenirs.

Collaborative efforts encouraged

Brigadier Maehlo Lento, reporting on behalf of the South African Police Service (SAPS) Provincial Commissioner, said: “Robbery incidents have subsided but we still need to make sure that we continue and collaborate with students and all other roleplayers to make sure that we sustain the safety.”

The collective participation sentiment was also reflected by Prof Prakash Naidoo, Vice-Rector: Operations. “We are hoping through our annual Safety Week to reiterate our commitment to the safety of students, as well as bringing all roleplayers together to reflect on areas of cooperation and collaboration in an effort to improve the safety of student.”

Not just physical safety

Issues of mental health were discussed by the Next Chapter student organisation, while Embrace a Sister student organisation spoke about femicide and the safety of women. The scourge of gender-based violence formed the focal point of the Gender and Sexual Equity office’s address. In addition the Student Counselling and Development division offered invaluable advice on where those who exhibit symptoms of depression can seek help.

Other stakeholders who contributed to the success of this year’s Safety Week were the Mangaung Metropolitan Municipality, Department of Police, Roads and Transport, as well as Sector 3 Community Police Forum.

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.
