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.

Mandela statues and the issue of public representation
2015-09-04

   

Prof Grant Parker, Associate Professor of Classics and Co-Director of the Centre for African Studies at Stanford University, USA, presented a public lecture on the Bloemfontein Campus on 27 August 2015, in which he explored the topic of ”Memorialising Mandela after Rhodes Must Fall”. What stories do the multitude of Mandela statues tell us about the man? Our society? Ourselves? These were some of the questions Prof Parker addressed during his lecture.

Paradoxes
Prof Parker discussed some of the paradoxes presented by the Mandela statues. The huge 9m high Mandela statue at the Union Buildings in Pretoria does not necessarily reflect his humility. Iconic statues strewn across the world do not reveal Madiba’s appeal. “Madiba’s charm,” Prof Parker said, “was all about his ability to relate to people of very different backgrounds. People who were his enemies would – to their surprise – find a humanity they were not expecting. It’s very hard to reconcile that with the colossal statues.”

Rhodes Must Fall
On the topic of the Rhodes Must Fall campaign, Prof Parker said that “the debates around it seem to express the frustration of deepening equality in general and lack of demographic change.” He also believes that, although the campaign centres on statues, there are much deeper issues at play that need to be addressed.

Artists should be part of the conversation
Prof Parker also advocated that artists’ voices should be incorporated into the creative processes of public art. “There is a much greater need for creative artists,” he concluded, “to be part of conversations, not only about what we as South Africans want to commemorate, but how we do that. I would very strongly suggest that this be done by non-figural representations.”
