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.

It was a proper party at this year’s Kovsie Stage Extravaganza, with red-hot performances by two of South Africa’s most celebrated artists.

Singers Lira and Karen Zoid had the audience in the Callie Human Centre at the Bloemfontein Campus on their feet with some of their greatest hits. With the artists on stage,were some of Kovsies’ most talented students, who hold their own among the two music stars.

Lira, a ten-time SAMA prize-winner, showed why she performed at US President Barack Obama's inauguration ball earlier this year. She had the audience eating from her hand with songs from her own albums, as well as from other artists. Between songs, she also offered advice to students and encouraged them to make their mark in life. "The knowledge you acquire here, will open doors for you," she told students, before singing favourite songs likeSomething inside so Strong, Rise Again and Ixesha.

Zoid, also a SAMA prize-winner, enchanted the audience with favourites like Afrikaners is Plesierig and Small world. Things heated up when she did a cover version of Johnny Clegg’s Asimbonanga with Kovsie students joining her on stage. She gave R200 to one lucky student to take his girlfriend for coffee later on.
