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.

The University of the Free State (UFS) took a further step in reducing its carbon footprint and its dependency on coal fired electricity with the installation of a solar heating system at one of its residences. The contractor handed the system over to the UFS on Wednesday, 2 June 2010.

The system installed at the Vergeet-my-nie Residence is the first commercial solar water heating project in both Bloemfontein and at the UFS. It is estimated that it will provide in 70% of the residence’s energy needs and save approximately R101 000 per annum in electricity cost. The project was completed at a cost of R2,4 million.

More residences at the UFS will be refurbished with solar systems as the existing heating systems in the rest of the twenty residences are due for replacement.

The energy crisis of 2008, and the challenges and necessity to reduce the use of electricity, sparked the initiative around the installation of solar heating systems at the UFS. The UFS is the second largest energy user in Bloemfontein.

Mr Nico Janse van Rensburg, Manager: Physical Planning at the UFS, says the management of the UFS saw an opportunity in the crisis and pro-actively embarked to become a market leader. Solar heating would not only alleviate the electricity problem of South Africa, but will impact the ever increasing electricity bill of the UFS.

“Protecting the environment and being on the cutting edge of technology are core issues to the UFS,” says Janse van Rensburg. “We are an educational institution and take pride in practicing what we preach.”
