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.

Statement by Judge Faan Hancke, Chairperson of the Council of the University of the Free State (UFS)
2008-03-08

The Council of the University of the Free State today (Friday, 7 March 2008) unanimously condemned the offensive and racist Reitz video in the strongest possible terms.

Council further labeled the video as an insult to women, to older persons and to poor working people who are defenseless and vulnerable and expressed its disgust at the action of the students concerned.

Council also apologised unreservedly and sincerely to the five UFS employees who were shown in the video and offered all emotional and counselling assistance necessary as well as in the current criminal matter under way or possible civil action they may undertake.

At the same time the university must also provide counseling to current first year students of Reitz who were not present at the time of the filming of the video.

Council also mandated the management, in addition to the other disciplinary steps under way, to consider the possibility of closure and of conversion of Reitz into a beacon of transformation, hope and liberation (either as a residence or in some other form).

This must take place in accordance with due process of the law to give residents and other stakeholders reasonable opportunity to make submissions so that all relevant considerations can be taken into account.

The Council expressed its full confidence in the management and supported the steps taken by management thus far under trying circumstances concerning transformation, residence integration, the Reitz video and the vandalism of the campus.

It reaffirmed the decision taken in June 2007 to increase diversity in student residences and recommitted the UFS to implement the policy.

The Council condemns all forms of racism and committed itself to eradicate racism and racial prejudice in any form and from any quarter on the UFS campus.

The meeting also approved the appointment of an external expert agency to assist the university in:

  • understanding and identifying the current challenges relating to the implementation of the integration policy 
  • supporting the university management and making recommendations on how to enhance the process of implementation

The intention is to provide additional capacity to the management in order to accelerate the transformation and integration process.

It called on management to take firm action against any staff or student who violates the law, is involved in threats, racism, disruptions, intimidation and vandalism and condemned these actions in the strongest possible terms.

The Council reassured all staff, students, parents and other stakeholders that firm action will be taken against persons who are guilty of disorderly conduct, intimidation, disruption or similar actions with the full force of the law.

The management was requested to maintain law and order so as to create a conducive environment in which academic excellence can be furthered. The Council appreciates the steps that have been taken in this regard.

The Council supported a management initiative to investigate the fundamental issues underlying many of the current problems in residences, including:

  • residence culture, including initiation, as well as race, racialism and racism
  • alcohol and drug abuse role,
  • place, organisation and management of residences constitution of student structures
  • and the role of political parties in student politics and structures
  • the physical structure of residences as part of a campus accommodation strategy

The Council agreed that social cohesion and racial tolerance will be highlighted as a strong theme in the academic cluster initiatives of the UFS and that management should find additional ways to strengthen existing programmes regarding diversity on the campus among all staff and students.

The Council called on all stakeholders to honour the high values of the Constitution of the country, to maintain these values and to further them in an orderly and peaceful environment.
