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.

Before and After Hector
2014-03-05

The apartheid years. The Anglo-Boer War. Mix these two topics together and you are ensured of a vigorous debate.

This was exactly the result at the Centenary Complex Gallery recently. During a round-table discussion, Kovsie students analysed an artwork by Gerrit Hattingh entitled “Before and After Hector”. The artwork depicts the iconic photo of Hector Pieterson – taken during the 1976 Soweto Uprising – staged as an event in the Anglo-Boer War.

The artwork functioned as the focal point at an exhibition curated by Angela de Jesus.The exhibition formed part of the International Research Forum hosted by the UFS which explored the topic of Societies in the Aftermath of Mass Trauma and Violence.

The ensuing conversation did not disappoint. The photograph evoked a wide range of views and emotions as the students reflected on the historic image representing violent and painful events of our collective past. As the students robustly exchanged their opinions, they developed strategies to support the reconciliation process. The dialogue assisted these students in formulating ways to look back at our history and use this knowledge to carry our society past traumatic experiences.

Prof Pumla Gobodo-Madikizela, Senior Research Professor in the Office for Research on Trauma, Forgiveness and Reconciliation, was astounded at the level of insight and wisdom the students displayed. “I am pleased that our students came to join us around the table to discuss this portrait which is iconic globally; to engage and also give their own interpretations of what they know, and what they do not know about our historical past. The dialogue about the interweaving of the Hector Pieterson photograph with the story of black victims of the British concentration camps is one of the ways of exploring the views of the younger generation in the aftermath of mass trauma and violence in our collective history,” Prof Gobodo-Madikizela concluded at the end of the conversation.
