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.

Meet our Council: Ndaba Ntsele – Inspiring entrepreneurs

 To call Mr Ndaba Ntsele just a businessman seems like a bit of an understatement. The Executive Chairman and co-founder of Pamodzi Group Limited lives and breathes business, entrepreneurship, and wealth creation. He is also a member of the Council of the University of the Free State (UFS) since September 2013.

His greatest passion is entrepreneurship, and sharing his ideas of self-employment with young (and old) South Africans. “I preach self-employment wherever I go. Everyone knows that unemployment is a major problem in our country. However, people often expect the government or big corporations to provide them with jobs. I like to influence people to start thinking about working for themselves, thereby creating opportunities for employing others,” he says.

His entrepreneurial drive extends even to his time on the UFS Council. Now in his second term, Mr Ntsele has been well placed to get a sense of the kind of contribution the university and its students could make to South Africa, and even further afield.  

“In addition to training students for all the other important industries in South Africa, I think the UFS is ideally situated to create agricultural entrepreneurs. The Free State is one of South Africa’s prime agricultural areas, after all. Food security is an issue worldwide, and it is an area in which we could make a real contribution by training food producers, food technologists, and agricultural specialists. In fact, I think the UFS could become the leading agricultural institution in the country.”

Being the best is something that he strives for continually, while high standards are not something he shirks. In fact, he believes that Council members should hold an institution accountable for maintaining the highest standards possible, whether it is in governance, financials, procurement, or any other areas of importance in an institution.

As the executive chairman of a multi-billion African-owned group with assets across the globe, Mr Ntsele does not have a great deal of free time. However, he enjoys sitting down with MBA students and graduates to share his views about entrepreneurship.

“If I can change their mind-set from ‘others must employ me’ to ‘I need to create my own employment’, then I will feel as if I have accomplished something,” he says.
