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.

UFS establishes links with the University of Ghent

2007-11-15

The University of the Free State (UFS) recently formalised its co-operation ties with the University of Ghent in Belgium. The two universities signed a memorandum of understanding during the Accenta Trade Fair, an annual event that incorporates activities such as business seminars, cultural events and exhibitions.

The signing of the memorandum of understanding took place via a live video conference linking the two institutions of higher learning.

“It was a wonderful moment because, after signing the memorandum of understanding on the Main Campus in Bloemfontein, the Rector and Vice-Chancellor, Prof. Frederick Fourie, actually showed us his signature on the screen while we were in Ghent”, said Prof. Koos Bekker of the Department of Public Management at the UFS, who was part of the delegation from the Free State.

The delegation consisted of the Premier, Ms Beatrice Marshoff, and several MECs and senior officials from the Free State provincial government, as well as the mayor, councillors and senior officials of the Mangaung Local Municipality. Several staff members of the UFS were also part of the delegation.

According to Prof. Bekker, the two universities will co-operate in various areas in terms of the memorandum of understanding.

“In the short term the collaboration will be focused on bio-fuels, public management and the digital divide, while discussions in other areas such as health services and organised crime are also under way,” he said.

As part of the memorandum of understanding, the following collaborative efforts are also envisaged:

Mr Lyndon du Plessis, a lecturer in the Department of Public Management, will be enrolled for a Ph.D. at both universities as from September 2008.

A research project involving both universities, the Mangaung Local Municipality and the City of Ghent, will be undertaken.
An investigation will be conducted by both universities regarding the possibility of writing a book on performance management in the public sector (negotiations with the publisher in this regard are under way).

An exchange programme involving students and staff from both universities will be established.

Academics from the UFS delivered papers during one of the forums that formed part of the Accenta Trade Fair programme in Ghent. Prof. Koos Bekker and Mr Lyndon du Plessis from the Department of Public Management delivered papers on strategic planning in practice on the first day of the event, which was devoted to scientific seminars. On the second day Prof. Lucius Botes, Director of the Centre for Development Support at the UFS, delivered a paper on economic development issues, and on the third day Prof. Gustav Visser, Associate Professor in the Department of Geography at the UFS, delivered a paper on tourism.

Papers on bridging the digital divide were presented during the video conference by academics in both Bloemfontein and Ghent.

As guests of honour at the Accenta Trade Fair, the Free State delegation was allocated the main exhibition floor space, covering 1 092 m². The Main Exhibition Hall covers a total surface area of 40 000 m². The Accenta Trade Fair attracts an average of 100 000 visitors annually. The UFS also participated as an exhibitor at the Trade Fair.

This visit was a follow-up of the previous visit, during which the Free State delegation was hosted by the City of Ghent and the provincial government of East Flanders for planning purposes from 14 to 24 April 2007.
