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.

Alumni inspired to keep flying the Kovsie flag high at reunion weekend festivities
2015-09-01

The University of the Free State hosted alumni from all over the country on the Bloemfontein Campus during a weekend of exciting events, talks, and tours around the campus on 28 and 29 August 2015.

The celebratory events were kick-started with a leadership symposium hosted by Dr Marcus Ingram, Director: Institutional Advancement with Adv Roelf Meyer. The symposium was attended by current student leaders and the SRC Presidents Alumni Association. In his dialogue with the audience, Adv Meyer shared his experiences and personal growth in the process of bringing about democracy in the country with student leaders as change agents. “If you really want to contribute to change, it is not only an intellectual exercise; it is also a heart and soul thing,” he said.

The anchor event was the inaugural Chancellor’s Distinguished Alumnus Award Luncheon hosted by Chancellor, Dr Khotso Mokhele. Prof Jonathan Jansen, Vice-Chancellor and Rector, welcomed guests by highlighting the latest extraordinary achievements of UFS students and academic staff.

Keynote speaker of the day, Ms Nozizwe Madlala-Routledge, Executive Director of Inyathelo and a renowned politician, spoke of the role that universities have in preparing women for leadership roles and how they, in turn, can prepare society for female leadership.  She commended the UFS’s advancement efforts supported by the Kresge Foundation, which supports young people, to keep them in universities. “I am proud to say that the UFS’s efforts in advancement have achieved its goals.”

In his remarks, Dr Mokhele said “what draws a student back to his/her Alma Mater is the quality of the experience they had on campus.  This campus contributed to the transformation of this country through alumni such as Roelf Meyer and Kobie Coetsee.”  He said this initiative should create a lived experience for students on the university campus.  The Chancellor presented the Distinguished Alumnus Award to Adv Roelf Meyer, for his outstanding contributions to the human interests of South Africa, and his current work of facilitating peace processes around the world.

In accepting the award, Adv Meyer introduced Youth Zones, a project which he has been involved with for the past five years, empowering and supporting 40,000 youths in the Free State. In accepting the award, he said “I was a first-year student in 1960, my year group represented the most emphatic group of this university. There are many who came before and after us who well deserve this award, therefore, I accept it on behalf of all alumni.”

To wrap up the weekend’s festivities, former SRC President, Richard Chemaly, hosted the Faculty of Law alumni cocktail event at the CR Swart Auditorium.
Speaking at the event, Prof Caroline Nicholson, Dean of the Faculty of Law, said “A faculty cannot exist without its alumni, we need you to carry us.  Your continued support and collaboration is truly appreciated.”

Alumni and staff enjoyed further entertainment by well-known musical groups, Freshly-Ground and The Muses.
