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.

Forgive and forget? Or remember and retaliate?
2015-10-08

Cover of the novel Kamphoer

Fact and fiction came together at the Bloemfontein Campus recently to discuss the traumatic repercussions of the South African War. The event forms part of a three-year project – headed by Prof Pumla Gobodo-Madikizela (University of the Free State Trauma, Forgiveness, and Reconciliation Studies) – which investigates transgenerational trauma in the aftermath of the South African War.

The discussion explored the theme, ‘Working through the Past: Reflections on the novel Kamphoer’.

Together, Emeritus Prof Chris van der Merwe (University of Cape Town) and the author of the novel, Dr Francois Smith (University of the Free State, Department Afrikaans and Dutch, German and French), engaged in a thought-provoking, insightful conversation, tracing themes of trauma and issues of forgiveness presented in Kamphoer. Prof Van der Merwe and Dr Smith demonstrated how both fiction and historical fact can inform our present, and guide us into the future.

discuss the novel Kamphoer and how the book relates to
current issues of transgenerational trauma.

“On a societal level,” Prof Van der Merwe said, “we need to work through trauma by putting it into words, and putting it into a narrative.” When it comes to historical trauma, should we forgive and forget, though? Or rather remember and retaliate? Neither, proposed Prof Van der Merwe. “What I want to plead for is the difficult challenge: remember and forgive.” But Prof Van der Merwe also pointed out that, although forgiveness blesses both the giver and receiver, it is an ongoing process.

Dr Smith agreed wholeheartedly. “One of the discoveries of my book is that forgiving is a continuous process. It’s not something that gets completed at a particular stage in your life. By the same token, you can’t say that you are ever able to leave the past behind.” These issues of trauma, forgiveness, the past versus the present, remembering and forgetting are all integral questions confronting the main character of the novel, Susan Nel .

They are also questions we, as a nation, are currently confronted with, too.

“At this moment in our society,” Prof Van der Merwe said, “we have enough killers. We have a greater need now for caring nurturers.”
