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 acts fast in expelling students for serious misconduct
2014-02-22

On the evening of Monday 17 February 2014, Muzi Gwebu, a fifth-year student in BCom Economics, while walking on the Bloemfontein Campus of the UFS, was side-swiped by a vehicle driving recklessly through campus. He followed the vehicle where it stopped at one of the residences and approached the two occupants. A confrontation started and he was assaulted by one of the occupants of the vehicle.

Gwebu sustained minor injuries and was immediately assisted by the university’s residence life division. He lodged a complaint of assault at the South African Police Service (SAPS).

The senior leadership of the UFS is shocked and outraged at this blatant act of violence against one of its students. The Vice-Chancellor and Rector, Prof Jonathan Jansen, says: “We regard this incident in a very serious light and we worked closely with the SAPS throughout the night to identify and locate the perpetrators who were driving with false number plates.”

With the assistance of the student leadership in one of the residences, the owner of the vehicle and his companion were traced this morning.

The two students were immediately handed to SAPS by the university’s Protection Services and were arrested on charges of attempted murder, assault and driving with false number plates.

In addition to the criminal investigation by the SAPS, the university is also conducting an urgent and formal investigation into the incident.

The university has offered Gwebu full counselling and support until he is fully recovered.

“It is sad and disappointing that, after so much progress with the social transformation of the UFS, such a horrific incident could have occurred. It is pleasing, however, that across the board, all our students condemned these vicious acts. The students, if found guilty in the criminal and institutional investigations, will definitely not be allowed to study at the University of the Free State,” he said.

Statement by Dr Willy Nel, Residence Head of Armentum men’s residence

The Residence Head, Residence Committee and all residents of Armentum male residence on the Bloemfontein Campus unequivocally distance themselves from any behaviour which does not breathe the letter and spirit of the University of the Free State's vision of Human Embrace and Academic Excellence. We work tirelessly to upend traditions that are contradicting this vision. Therefore we add our voice to those who condemn the incident in which ex-residents allegedly assaulted a pedestrian who is also a student of our institution. We express our support to and confidence in the university's and other processes to find justice in this matter.

Dr Willy Nel
Residence Head: Armentum
