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.

Armentum and Emily take honours in first combined SingOff attempt

A few months before the McDonald's SingOff finals, they almost didn’t have a group. But on 19 August 2017, Emily Hobhouse and Armentum were the big winners in the Kovsie Church.
In the second annual SingOff – with many new additions – combined serenade groups could take part for the first time. Emily and Armentum were crowned best combined group, and were the overall winners. Armentum followed up their 2016 performance when they won their first ever serenade competition as best male residence.
According to Tato Mpeteng, RC Arts and Culture of Armentum, the praise must go to Zoë Adonis. “She is a Music student and the RC Arts and Culture of Emily. She was our coach. She didn’t ask for any fee, and we put her under a lot of stress. She sacrificed a lot,” he says.

“We almost didn’t have a SingOff group two months ago, because we didn’t have participants.”
Villa Bravado was the best male residence and finished second overall, while Kagiso was second in the combined group category. Harmony took the honours as best female group, with Soetdoring the runners-up. Vishuis was the second-best male residence.
