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.

FF Plus court case against UFS withdrawn
2007-10-23

The University of the Free State (UFS) is pleased to announce that a Supreme Court application to have the racial integration of its student residences set aside has been withdrawn unconditionally by the Freedom Front Plus (FF+). The political party has offered to pay the assessed costs of the UFS.

The Rector and Vice-Chancellor of the UFS, Prof. Frederick Fourie, welcomed this decision by the FF+, saying all energy should now be focused on making a success of this very important nation-building initiative in the student residences. “We have been convinced all the time that we had followed a fair and inclusive consultation process which led to a thorough and well-considered decision by the Council,” he said.

The decision to integrate student residences as from January 2008 was approved by the UFS Council on 8 June 2007. This last decision was confirmed by the Council – which is the highest decision making body at the UFS -  on 14 September 2007 with an overwhelming majority, with only one vote against.

“There is now no legal obstacle to student participation in the work being done to implement Council’s decision. In fact I want to urge all students in our residences to play an active role in implementing Council’s decision,” he said.

According to Prof. Fourie much work has been done in preparation for the intake of first-years into the residences in January 2008.

Since the initial decision of 8 June 2007, the Vice-Rector: Student Affairs, Dr Ezekiel Moraka, has been leading a team of staff members and student representatives who are doing work in various sub-task teams.

“One of the main reasons for working in this way through sub-task teams, is to ensure the widest possible participation of the affected students in the implementation of the Council’s decision,” said Prof. Fourie.

These sub-task teams are working on aspects of residence life in order to make the racial integration of residences as successful as possible. These aspects of residence life include, among others:
 

  • governance structures
  • traditions and character of residences
  • diversity education and training
  • security
  • placement and recruitment

“This list is not exhaustive, but merely to illustrate the kinds of areas being looked into. I would like to encourage all students in residences to make an input into the work of these sub-task teams through the primes, the Student Representative Council (SRC) or through the offices of the Dean or the Deputy Dean of Student Affairs.

“We have already begun to implement an interpreting service at the house meetings of three ladies residences, namely Emily Hobhouse, Roosmaryn and Vergeet-my-nie. From next year this service will be extended to other residences on the Main Campus,” said Prof. Fourie.  

“In the light of withdrawal of the court case, I am appealing to all students in our residences, to join hands with fellow students and with management in creating a campus of respect and appreciation for all languages, cultures and backgrounds,” he said.

“We want our students to assist the UFS in successfully managing the rich diversity on this campus, particularly in its student residences, and in so doing become an example to South Africa of a truly non-racial, multi-cultural and multi-lingual campus, where students are appropriately educated for the workplace,” Prof. Fourie said.
