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 don’t see myself as a star, says Wayde

The environment surrounding him has changed a lot over the past few weeks, but Wayde van Niekerk doesn’t see himself as superstar. The 400 m Olympic champion is embracing being back home and is feeling the love of the Kovsie family that helped him reach great heights.

“I see this (the Bloemfontein Campus) as a place where I can find peace,” the University of the Free State (UFS) athlete said at a celebration ceremony on 15 September 2016 for him and fellow Olympian, Rynardt van Rensburg. The event celebrated their achievements after participation in the Olympic Games in Rio de Janeiro, Brazil. Their coaches, Tannie Ans Botha and Derek van Rensburg, were also honoured.

Van Niekerk looks ahead
“I am always excited to get back home,” Van Niekerk said. Everybody who means something to him is in Bloemfontein and on this campus. “I thank you for believing in me. I am only 24 years old and still have quite a few years left to keep on doing what I do.” He also conducted the official opening of the new KovsieFit gymnasium in the Callie Human Centre.

According to Prof Nicky Morgan, acting Vice-Chancellor and Rector, the attendees had “Wayde fever”. “We can’t really say thank you enough – at least for the association we have had with you (Van Niekerk) over the years.”

Rynardt didn’t expect best in Rio

 “I see this (the Bloemfontein Campus)
as a place where I can find peace.”

Van Rensburg reached the semi-finals in Rio and ran a personal best of 1:45.33 in the 800 m. “If we don’t have support, we won’t be able to do this,” he said.
Although his form was improving prior to the Olympics, he didn’t expect to run a personal best. “My dad (and coach) kept believing in me and telling me it is possible to do.”
