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.

Food insecurity at university campuses a growing threat
2015-07-28

Food insecurity on university campuses in South Africa has come to the fore as one of the more pressing subjects that needs to be tackled to ensure the continuing education of disadvantaged students across the country.

On Friday 14 August 2015, the University of the Free State will host the first higher education colloquium on food insecurity on university campuses.  The one-day colloquium will take place during the Arts and Social Justice Week, in collaboration with the UFS’s Institute for Reconciliation and Social Justice Best practices will be shared, exploring the available research on student food insecurity at institutions of higher education.

Food insecurity has emerged as a pressing social justice issue affecting students countrywide. Action needs to be taken to promote the academic success of students, who will ultimately contribute to the country’s economic growth. One of the primary focus areas of the colloquium will be to establish a common practice to address this need.  Universities leaders, staff from wellness and social work departments, and SRC members from across the country who have been invited, and are expected to attend, are the University of Pretoria, the Tshwane University of Technology, North West University, UNISA, and the Central University of Technology.

Professor Jonathan Jansen will participate in a panel discussion alongside Ruda Landman and Prof Edelweiss Wentzel-Viljoen (HPCSA). This promises to be an inspiring meaningful dialogue, by asking the difficult question:  How do we change the food insecurity situation at universities?

The University of the Free State is currently the country’s leading university in addressing food insecurity on all its campuses through its flagship No Student Hungry Bursary programme, which has funded more than 500 students since it was established in 2011.
