UFS puts first solar-powered vehicle on the road

UFS Sasol Solar car — Team UFS, which has entered its solar-powered vehicle, Lengau (meaning Cheetah in Sesotho), will compete against more than 11 other teams, both local and international. Pictured here is the entire team during one of the road tests at Brandkop in Bloemfontein.

It is almost three years after Team UFS first decided to put a solar-powered vehicle on the road. Within a few days, this dream of participating in the international Sasol Solar Challenge will become a reality when they depart from Carnival City in Johannesburg on 9 September 2022.

For the challenge, the team of ten members will stop at six points between the departure point and the V&A Waterfront in Cape Town, where they will arrive on 16 September 2022.

Completing the estimated distance of 2 500 km

“The team that finishes with the greatest distance covered within the allotted time, will win the challenge,” says Dr Hendrik van Heerden from the UFS Department of Physics and project manager of Team UFS.

The UFS, which has entered its solar-powered vehicle, Lengau (meaning Cheetah in Sesotho), will compete against more than 11 other teams, both local and international.

Dr Van Heerden’s two main objectives in entering the challenge, are to build a solar-powered vehicle robust enough to complete the estimated distance of 2 500 km during the 2022 Sasol Solar Challenge. Furthermore, he aims to establish capacity in the students and staff through acquired practical knowledge on the management, design, construction, and actual racing of solar-powered vehicles, which is to form the basis for participation in future projects and event competitions.

Bringing together expertise from the UFS Departments of Physics, Engineering Sciences, Computer Sciences and Informatics, Electronics and Instrumentation, and Geography, the team of 23 started with the construction of their vehicle on 18 October 2021.

Just over 10 months later and the car is fully functional, already passed a few road tests, and the crew is ready for the big challenge ahead.

The three drivers, Albert Dreyer, Monica van der Walt, Denver de Koker, together with back-up driver Lukas Erasmus, will travel on public roads via a predefined route over eight days, driving every day between 07:30 and 17:00. The aluminium-frame vehicle will weigh up to 370 kg, including the frame, the five solar panels, and the driver, and can reach a maximum speed of 60 km per hour (they aim to average 45 km/hour).

According to the Sasol Solar Challenge rules and regulations, no driver is allowed to drive for longer than two hours. The capacity of the batteries and the availability of sun will determine how often the drivers will need to stop to recharge the solar batteries.

Popularising electric vehicle technologies

This is the first time that Team UFS will be participating in the Sasol Solar Challenge. A guardedly optimistic Dr Van Heerden says their goal is to complete the full distance without breakages, and to accumulate as much knowledge and information as possible. With the next Sasol Solar Challenge in two years’ time, they plan to enter again.

“Our long-term aim is to continually improve on the design, technology, science, and project implementation to participate in events and challenges around ‘green’ energy and relevant technologies. An additional aim is the popularisation of electric vehicle (EV) technologies through outreach programmes,” says Dr Van Heerden.

Prof Koos Terblans, Head of the Department of Physics, says one of the key benefits of this project was that the group, consisting of personnel and students from different departments, learned to work together as one team. “Together, they worked and made plans to collect and apply the maximum amount of energy. Looking at the bigger picture, they are solving a worldwide problem, that of harvesting and applying energy. I am very excited that they have come this far; this is a first for the university.”

Team UFS will compete against more than 11 other teams, both local and international.

The teams will depart on 9 September from Carnival City in Gauteng to reach their destination at the V&A Waterfront on 17 September

UFS boasts with most advanced chemical research apparatus in Africa

The University of the Free State’s (UFS) Department of Chemistry now boasts with some of the most advanced chemical research apparatus in Africa after the latest addition, a nuclear magnetic resonance (NMR) spectrometer, was inaugurated today by the Rector and Vice-Chancellor, Prof Frederick Fourie. The NMR is used to analyse molecular structures.

Last month the Department of Chemistry celebrated the installation of the most advanced single crystal X-ray diffractometer in Africa. The diffractometer provides an indispensable technique to investigate among others the solid state of compounds for medicinal application.

“Three years ago the UFS executive management realised that, if we want to build a university of excellence, we should invest in research. We started to think strategically about chemistry and decided to bring the apparatus at the Department of Chemistry on a more competitive standard. Strategic partnerships were therefore secured with companies like Sasol,” said Prof Fourie during the inauguration ceremony.

“The installation of the NMR symbolises the ability of the UFS to turn academic areas around. I hope that this is the beginning of a decade of excellence for chemistry at the UFS,” said Prof Fourie.

”The catalogue value of the Bruker 600 MHz NMR is approximately R11 million. With such an advanced apparatus we are now able to train much more post-graduate students,“ said Prof Jannie Swarts, head of the Division Physical Chemistry at the UFS.

”The NMR is the flagship apparatus of the UFS Department of Chemistry that enables chemists to look at compounds more easily at a molecular level. Research in chemistry is critically dependent on NMR, which is a technique that can determine the composition of reactants and products in complicated chemical reactions, with direct application is most focus areas in chemistry,“ said Prof Swarts.

”Parts of the spectrometer consists of non-commercial items that were specifically designed for the UFS Department of Chemistry to allow the study of unique interactions in e.g. rhodium and platinum compounds,” said Prof Swarts.

According to Prof Swarts the NMR enables chemists to conduct investigations on the following:

To evaluate for example the complex behaviour of DNA in proteins as well as the analysis of illegal drugs sometimes used by athletes.
It provides an indispensable technique to investigate compounds for medicinal application for example in breast, prostate and related bone cancer identification and therapy, which are currently synthesised in the Department of Chemistry.
It can also be applied to the area of homogeneous catalysis where new and improved compounds for industrial application are synthesized and characterised, whereby Sasol and even the international petrochemical industry could benefit. This analytical capacity is highly rated, especially in the current climate of increased oil prices.
The NMR can detect and identify small concentrations of impurities in feed streams in the petrochemical industry, e.g. at Sasol and also the international petrochemical industry. These minute amounts of impurities can result in metal catalyst deactivation or decomposition and can cause million of rands worth in product losses.
It is indispensable for studying the complexity of samples that is non-crystalline. These materials represent the vast majority of chemical compounds such as solvents, gasoline, cooking oil, cleaning agents and colorants as examples.

According to Prof Swarts the general medical technique of MRI (magnetic resonance imaging) in use at larger hospitals, is based on NMR technology.

”The NMR apparatus enabled the Department of Chemistry to characterise complex molecules that were synthesised for the multi-national company, FARMOFS-PAREXEL, and to negotiate research agreements with overseas universities,” said Prof Swarts.
