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 increases admission requirements
2010-07-26

Admissions criteria for entry to undergraduate programmes at the University of the Free State (UFS) will be increased with immediate effect. This means that students who begin their undergraduate studies in 2011 will need to meet the new admissions criteria in order to register.

“Increasing admissions requirements is a critical component of our unwavering commitment to excellent academic standards and educational quality at the UFS,” said Prof. Driekie Hay, Vice-Rector: Teaching and Learning at the UFS.

“The challenge of student success at most South African universities is something that has attracted increasing attention over the past few years. We believe that it is our responsibility as an educational institution to admit students that we are confident are likely to be successful, and also to provide the very best quality of teaching and learning to ensure success.”

The university is also acutely aware that large numbers of young people in the country attend schools that are not adequately resourced to provide the quality of schooling needed for successful university study.

“We are thus committed to working with schools and with talented learners in order to address this challenge,” said Prof. Hay.

“The university currently has several initiatives in this regard. Further, our innovative and extremely successful University Preparation Programme (UPP) provides an opportunity for students with potential who do not meet the university entrance criteria to complete a bridging year that prepares them for the rigours of university.”

For students who begin their studies in 2011 the following changes will come into effect:

  • The minimum requirement for entry into undergraduate programmes will increase from 28 points to 30 points.
  • The minimum requirement for entry into extended programmes will increase from 23 points to 25 points.
  • The minimum requirement for entry into the University Preparation Programme will increase from 17 points to 20 points.
  • Subject-specific requirements specified by faculties will remain the same, except for Natural and Agricultural Sciences (contact the Faculty Manager at 051 401 3199).
  • All programmes that already require a minimum score of 30 points and above will not be changed.
  • The minimum entrance criteria for the B.Ed. Foundation Phase and B.Ed. Intermediate Phase will increase from 23 points to 25 points.
  • The minimum entrance criteria for B.Soc.Sc. Nursing will increase from 28 to 29 points.

Performance in the National Benchmark Tests will be used for placing students into academic support modules as needed.

These test results will not be used for admissions decisions in 2011, except for Faculties where it is used as part of their selection process.
Prospective students are encouraged to submit their applications for study in 2011 as soon as possible.
For telephone enquiries, please dial 051 401 3000.
