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.

Learning Afrikaans for foreign-language speakers

Staff Development of CHESD and the Department of Afrikaans and Dutch, German and French, offers the following professional enrichment programme:

Learning Afrikaans for foreign-language speakers

The course start on Tuesday, 17 February 2009 (introductory meeting) at 17:00 in the Benito Khotseng Building, E-Learning Laboratory, room 107B. The contact time is two hours per week for ten weeks. Ms Ida Meiring, Department of Afrikaans and Dutch, German and French will present the course. Contact her at x2816. The closing date is Wednesday, 16 February 2009.

Please confirm your attendance with Ms Clidean Swiegelaar at swiegcc@ufs.ac.za. For any enquiries regarding the course you can contact Prof. Angelique van Niekerk, Department of Afrikaans and Dutch, German and French at vnieka@ufs.ac.za or x2339/2816.

More information about the course is available at:

Would you like to learn to speak Afrikaans? Every semester the Department of Afrikaans and Dutch, German and French offers a very basic as well as a little more advanced CD-ROM course for foreign-language speakers who have little or no prior knowledge of Afrikaans. The duration of the course is ten weeks and classes usually take place on Tuesday and Thursday evenings. Successful participants will receive a certificate. Use is made of Afrikaans language jokes and Afrikaans music in the course, which promotes self-activity. Contact Mrs I Meiring at meiringi@ufs.ac.za for enquiries.

The course and CD are offered free of charge to staff members who enrol, whilst persons who are not employed by the university pay R800 per course.
