Prof Richard Ocaya from the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) Qwaqwa  Campus has achieved a significant milestone with a newly patented invention. This patent, developed in collaboration with researchers from Turkey and Saudi Arabia, is the result of work that began in 2017, focusing on a special material known as graphitic carbon nitride.

This breakthrough in temperature measurement technology aligns perfectly with the university's Vision 130 commitment to innovation and addressing global challenges. The new device offers a unique solution to a longstanding issue in the field, providing accurate temperature measurements across an extremely wide range. Existing solutions often require multiple devices, leading to increased costs and reduced accuracy, but this invention simplifies the process.

The device, based on a combination of graphitic carbon nitride and silicon, can measure temperatures from -250°C to 250°C with exceptional consistency and linearity. This range and accuracy set it apart from current technologies, making it suitable for various applications, from standard temperature measurement to specialized settings involving extreme temperatures. It could be especially valuable in deep-space exploration, where equipment faces drastic temperature fluctuations.

The patent underscores the university's commitment to fostering collaborative research, a key aspect of Vision 130. Prof Ocaya attributes the success of the invention to the robust nature of the team, established in 2015. The team is now seeking to commercialize the technology by licensing it to a suitable partner, with organizations like NASA expected to show significant interest.

Prof Ocaya advises other academics considering patenting their inventions to ensure the patent solves a real problem uniquely and is based on sound principles. This makes the invention reproducible and protects it from being copied, assigning exclusive rights to the patent holder. Patenting allows for either manufacturing the devices or licensing them to third parties for royalties and profit. He notes that the main consideration is that the innovation must be practical and solve a specific problem in a novel and commercially viable way. He also acknowledges the challenge many academics face, as the "publish or perish" mentality often leads to choosing scientific articles over patents.

Despite securing the patent, Prof Ocaya and his team continue their research efforts, exploring new possibilities while balancing practical research with academic pursuits. He believes the invention will significantly impact the field of temperature measurement, being integrated into many new designs requiring such measurements.

The university proudly supports this innovative research and anticipates its real-world impact, furthering Vision 130's commitment to increasing UFS's research capacity and capability.

“I will continue to try and make you guys proud and represent Kovsies in a positive light.” With these words Wayde van Niekerk thanked his University of the Free State (UFS) family and emphasised the importance of this community in his life.

After returning from the Olympic Games in Rio de Janeiro, Brazil, the 400 m Olympic champion made his first appearance on the Bloemfontein Campus at Mooimeisiesfontein on 9 September 2016. This formed part of a hero’s welcome on an open-top bus, arranged by the Department of Sport, Arts, Culture and Recreation. The bus also stopped at Hoffman Square, Grey College, the Mangaung Outdoor Sports Centre, and Twin City Mall in Bloemfontein.

However, UFS students and staff will have their own opportunity to honour this achievement in true Kovsie spirit with a celebration ceremony on 15 September 2016 on the Bloemfontein Campus. Van Niekerk and fellow Olympian Rynardt van Rensburg, who reached the semi-finals in Rio and ran a personal best of 1:45.33 in the 800 m, will be welcomed back with this special event.

A humble Van Niekerk isn’t known for many words and his brief visit at Mooimeisiesfontein was no exception.

“Thank you to everyone who came out to support me,” he said from the open-top bus to a festive crowd close to the Main Entrance of the UFS.

“I really appreciate each and every one of you. It is something I will always cherish.”
