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.

Enough is enough. The UFS took a vocal and visual stand against gender violence and rape with a march joining the national protest movement. With banners reading: ‘No to rape,’ ‘Stop sexual terrorism’ and ‘Enough is enough’, hundreds of Kovsie men and women took part in the Enough is Enough: Are you man Enough march held on the Bloemfontein Campus. Led by Mr Rudi Buys, Dean of Student Affairs, staff and students, mostly men, told the world what they think about the scourge of violence and rape in the country.

Addressing protestors, Prof Jonathan Jansen, Vice-Chancellor and Rector, highlighted shocking rape statistics, saying that it is dangerous to be a woman these days with a woman raped every minute somewhere in the country. “Women can hardly breathe without being worried.Culture has deceived our young men. The country is experiencing a tragic time. We need to raise our children, mostly boys, to respect women from an early age. They must also learn how to deal with their emotions – boys must learn how to cry.”

Joining Prof Jansen on stage was the Student Representative Council (SRC) presidents of three universities in South Africa – William Clayton from the UFS, Horne Hallendorff from the University of Cape Town and Clinton du Preez from Stellenbosch University. “Enough is indeed enough and men should take their role seriously to ensure that we say NO to gender violence and rape against women,” Clinton told protestors.

At the request of the Dean of Student Affairs, all the men that were present kneeled as a sign of apology of the selfish acts of men against women.

The university will continue the fight against gender violence with a series of dialogues creating awareness, but also facilitating broader understanding of gender violence.
