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.

New Rector and Chancellor inaugurated at UFS

NEW RECTOR AND CHANCELLOR INAUGURATED AT UFS

 Newly inaugurated Rector and Vice-Chancellor of the University of the Free State, Prof Frederick Fourie, has recommitted the university to the service of the broader community, through the pursuit of academic excellence and contributing to building a non-racial, democratic and just South Africa.

To make this a reality Prof Fourie proposed a social contract or accord between university constituencies and the community to chart the way forward to establishing a university that can meet the challenges of a developing democracy.

Prof Fourie was speaking at his inauguration ceremony on the Bloemfontein campus, where the former Ambassador to the United States, Dr Franklin Sonn, was also inaugurated as Chancellor of the UFS.

The twin inauguration ceremony – the first in the history of the UFS - was attended by former President Nelson Mandela, Education Minister, Kader Asmal, Free State Premier Winki Direko, and the executive mayor of Mangaung, Mr Pappie Mokoena, who all endorsed the appointments as evidence of the transformation of the UFS.

According to Prof Fourie, the greatest contribution that any university could make to social and economic development in South Africa was by being an excellent university that encouraged critical inquiry, scientific knowledge as well as community service.

“So whilst we cherish and foster the continuity of the university as part of the ageold international tradition of universities, this University embraces its particular role in this country now, embraces the changes in the form and scope of its role in this crucial period of our history. We are committed to making a real difference to the new nation,” he said.

His vision for the UFS was “to be a university of excellence, equity and innovation – a leader in research, teaching, community service, adult learning, transformation, non-racialism, non-sexism, multi-culturality and multilingualism – a contributor to our country and our continent’s growth and development – a truly South African university”.

Prof Fourie said the recent incorporation of the Qwaqwa campus of the University of the North into the University of the Free State, which is the first such incorporation to take place, would contribute to broadening access for poor communities to higher education. Introducing an innovation to the inauguration ceremony, Prof Fourie and the UFS staff pledged to their commitment to excellence and justice, quality and equity. Fourie is the 13th Rector of the University of the Free State, succeeding Prof. Stef Coetzee, and Dr Sonn is the 6th Chancellor, succeeding Ms Winkie Direko, Premier of the Free State.

In his inaugural address, Dr Sonn said the significance of today’s ceremony was that the UFS - as a former institution of the Afrikaner – had chosen to walk the path of justice and not merely survival. “This university has seemingly liberated itself. It is inclusively South African.

He said the academic community must play its role of vigilance and not indifference”. Referring to the stature of former president Mandela in international affairs, Dr Sonn said: “We must bring the weight ot science and critical analysis and interpretation to bear in support of Madiba and other moral giants.”
