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.

Music was always something this singing sensation wanted to do from a very early age.

Sonet du Plessis, more famously known by her stage name, Hailey Clark, is a third-year BA Drama and Theatre Arts student at the University of the Free State (UFS). Her electronic pop debut album, titled Deurmekaar, was finally launched after a year of hard work and sacrifice.

Success in English and Afrikaans

Hailey, whose album features Afrikaans and English songs, says her music is influenced and inspired by a variety of local sounds and artists. “Dirk van der Westhuizen and Refentse – a new and upcoming artist – are two of the locals I look up to,” she says.

Reaching success at such a young age is the result of setting goals and achieving them. “Success is when you grow as a person and an artist in your music. You need to enjoy every moment of what you do and share it with other people,” Hailey says.

Future music producer and actress

With a bright future ahead of her, Hailey wants to become a full-time musician, but also wants to focus on acting, especially in films. “I want to perform as much as possible and hopefully become a music producer. I also have plans to do some acting as well.”

For all those who dream of becoming a musician, it’s hard work, Hailey says. “You have to know it is something you want to do and you have to commit to it. If it is what you want, keep focused and surround yourself with positive and encouraging people.”
