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.

Colloquium focuses on rural education
2012-10-10

Some of the international delegates during the second annual colloquium on rural education recently held at the Qwaqwa Campus.
10 October 2012

 The second edition of the Sustainable Rural Learning Ecologies (SuRLEc) Colloquium was held at the University of the Free State's Qwaqwa Campus this week. This three-day international event provided the Faculty of Education's postgraduate students with a platform to present their research and to learn from experienced researchers from all over the world.

In his opening address, the Faculty's Programme Head, Dr Dipane Hlalele, challenged all delegates to translate their research into achievable goals to address all the challenges facing rural education.

"Excellence in teaching and learning in a rural context remains a challenge for all sectors and levels of the education endeavour," Dr Hlalele said.

"Urban and metropolitan schools, colleges and universities may unintentionally structure their learning programmes in such a manner that they neglect rural attributes. This results in the marginalising of learners and students from rural environments. To complete the loop, these institutions are more likely to fail in preparing graduates for decisive contributions to sustainable rural learning ecologies," Dr Hlalele added.

The colloquium was officially opened by the Vice-Rector: External Relations, Dr Choice Makhetha, who highlighted the fact that the UFS was already doing its bit in levelling the learning playfields in higher education.

"We are aware that many of our students who come from disadvantaged backgrounds find it hard to cope at university. As a result, we are not waiting for them to come through to us. We are already in partnership with a number of schools where we help learners to improve their results," Dr Makhetha said.

The crucial role played by rural teachers was celebrated during a gala dinner to honour and acknowledge their efforts despite a myriad of daily challenges.

Ms Jabulile Mabaso (The Mills Primary Farm School) was honoured for 'Excellence in multi-grade teaching in Foundation and Intermediate phases'. Ms Rekha Mathew (Sibonakaliso Primary Farm School) and Mr Andries Motsoere (Tshebedisano Primary Farm School) were awarded for 'Excellence in managing multi-grade curriculum'.

The 2012 SuRLEc Honorary Award went to Ms Motshedisi Damane for her valuable contribution to the development of rural education in the Thabo Mofutsanyana Education District. Last year's recipient was the Dean of the Faculty of Education, Professor Dennis Francis.

Delegates and keynote speakers came from Thailand, Malaysia, the Unites States of America as well as the SADC countries of Botswana, Zimbabwe and Lesotho. South Africa was represented by the Universities of the North-West, Limpopo, KwaZulu-Natal and CUT, amongst others.
