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.

The Kresge Foundation has awarded $400 000 (about R4 million) to the University of the Free State (UFS) to increase student success through improved data analysis.

This four-year grant, as part of Kresge’s Siyaphumelela initiative, was recently announced by Mr Rip Rapson, Kresge’s President and Chief Executive Officer. This announcement was made at a symposium on South African higher education and philanthropy in Cape Town.

“Universities across South Africa are grappling with how to improve persistence and graduation rates for their black students in particular,” Mr Rapson said. “These universities will work together with the South African Institute for Distance Education to develop their data analytics capacity to find and share solutions and interventions based on solid information to improve student success.”

The UFS was only one of four universities receiving funding from Kresge. The other universities include the Nelson Mandela metropolitan University in Port Elizabeth, the University of the Witwatersrand in Johannesburg and the University of Pretoria.

The grants will help the universities build their capacities to use data to better integrate institutional research, information communication technology, academic development, student services and academic departments. Beyond the improvements sought for the UFS, Kresge hopes to see new approaches to data become mainstream for higher education in South Africa.

The Siyaphumelela initiative provides four years of institutional support and hope to create a community of practice that learns lessons that may benefit not only individual institutions and the cohort, but also potentially all of South African higher education.

Dr Lis Lange, Vice-Rector: Academic at the UFS, said improving student successes is a university goal that operates in the interface between the Human and Academic Projects of the university.

“We are delighted to be part of an initiative that is going to help us develop greater capability for data analytics and deeper integration between data and teaching and learning practices; and, at the same time, will bring the Centre for Teaching and Learning, the Directorate for Institutional Research and Academic Planning (DIRAP) and the faculties into a closer cooperation.”

Over the past four years donor income to the UFS increased considerably, both from governmental sources, trusts and foundations. By the end of 2013, governmental funding increased from about R5 million in 2011 to over R35 million. Funding by trusts and foundations increased from R5 million in 2011 to over R15 million in 2013. A general increase of 25% in funding is expected for 2014.

Dr Marcus Ingram, UFS Director for Institutional Advancement, says as the UFS begins to settle into a refined academic identity, the Department for Institutional Advancement intends to support these efforts by helping to facilitate the telling of a more integrated narrative to the university’s friends, prospects and donors.
