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 UFS issues a statement regarding the outcome of recent court case
2014-09-15

A significant number of reports appeared in the media the past week regarding this alleged attack, which happened on the Bloemfontein Campus of the UFS on 17 February 2014.

Although the senior leadership of the UFS is always in favour of good and objective journalism, we find it unfortunate that some of the facts are reported in a misleading and/or inaccurate way by some of the local media.

It is important to us that the true facts are stated. Not only for the sake of those involved, but also for our staff, students, alumni and other important stakeholders.

Here are the facts:

1.    The university was not the complainant. The alleged incident was reported to the South African Police Service (SAPS) by the victim, Muzi Gwebu, and the charges were laid by the State.

2.    At no point did the university management in any of its public statements describe this incident as a case of racism; not once. Charges of racism, then and now, must be proven, not assumed to be true simply because someone alleges racism. That is our standard approach, then and now.

3.    Cobus Muller and Charl Blom were suspended by the university, not expelled – pending the results of the court case. Emotions were running high among members of the student body and, on grounds of the evidence available to the university management at the time, as well as concerns for student and campus safety, they were suspended pending the outcome of a court hearing. This is normal procedure. Suspension does not mean you are guilty; it means you have a case to answer, either according to the university's disciplinary procedures or in the courts. For these reasons the university management will not apologise for the suspension.

4.    The university awaited the outcome of the court case before deciding whether disciplinary action should also be taken against Cobus Muller and Charl Blom. In the light of both the South African Human Rights Commission (SAHRC) and the Regional Court rulings, the university management subsequently decided to lift the suspensions of both Muller and Blom from all campuses of the university with immediate effect.

Muzi Gwebu laid serious charges with the SAPS almost immediately after the incident, and the university management believed, on the evidence then available, that the students had a case to answer.
 
5.    As the Director of Public Prosecutions decides on who will be prosecuted and who not, there are no grounds for the university to pay the legal fees of any of the students in this case.
 
Finally:
The University of the Free State will not be fazed by inaccurate and distorted information, rumour and exaggerations. We are still striving to become a truly excellent university, with a focus on the academic, but also the human development of our students.
