Staying safe during the coronavirus pandemic extends to ensuring that students at the University of the Free State (UFS) are safe from crime. Crime in South Africa remains an unfortunate reality which continues to affect students, staff and the institution in general. 

“Crime requires constant vigilance from the community and this can only be achieved through initiatives that are aimed at informing the community on what to do and what not to do. To this end the BSafe Safety First flyer is geared at informing specifically the student community on safety measures that must be taken,” said Cobus van Jaarsveld, Assistant Director: Threat Detection, Investigations and Liaison at Protection Services.

The Safety First flyer is a guide for students to be crime-conscious whether at their accommodation, on the street, or in their vehicles. It also offers tips on how to act responsibly as far as alcohol and drugs are concerned.

Engaging students on their safety 

UFS Protection Services recently engaged with off-campus residence students in Bloemfontein in order to provide tips on how to stay safe in their neighbourhoods. During the engagement, the new Safety First pamphlets were distributed, and students were encouraged to join the Student Crime-Stop Brandwag WhatsApp group.

As from 15 June 2020, Nissi Armed Response was deployed from 18:00 to 06:00. This initiative has already led to them responding to several suspicious persons and vehicles, as well as some minor incidents and disturbances. Two arrests were made on different occasions as a result of the deployment. In the first incident, a suspect was arrested on 27 June 2020 after a burglary in Brandwag, and the second relates to a suspect who was arrested on 10 July 2020 after threatening students at Universitas.

These successes were the result of student and community participation in providing information, coupled with excellent response from private security companies, including Nissi Armed Response, VR Security, and BloemSec.

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.
