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.

KovsieTennis wins gold at USSA – again
2014-12-10

The annual University Sport South Africa (USSA) tournament was hosted by the KovsieTennis Club from 1 – 5 December 2014 in Bloemfontein.

This year was the first time that KovsieTennis entered two teams in the tournament. Our first team played in section A, while our second team competed in section B. Both sections were divided into two pools with round robin matches during the first three days. Thursday presented the cross-over with the finals taking place on that Friday.

During the round robin phase, our first team beat Rhodes University, University of Witwatersrand and University of Pretoria. On the Thursday, they met North West University (Pukke) in the semi-final and beat them 8-5 in matches. The last match was not played, since Kovsies already won the semi-final. For the third year in a row, Kovsies faced Stellenbosch University (Maties) in the final. After some brilliant tennis in sweltering heat, Kovsies found themselves 7-5 down in matches with the last two mixed doubles still to be played.

Janine Erasmus and Duke Munro, as number one couple, and Arne Nel and Heidi Murray, as number two couple, played outstanding mix doubles to win both matches, tying the score on 7-7. Due to the fact that Kovsies lost three of their matches in three sets they were crowned champions, winning with 17-14 on sets.

It is the eighth year in a row that the Kovsie club managed to win gold during USSA. We are also the only team that has won the tournament since the format changed to combined teams from 2010.

After the tournament Arne Nel, Duke Munro and Christi Potgieter were included in the squad from which a team will be selected, should tennis feature at the World Student Games in Korea during July 2015. Janine de Kock , KovsieTennis manager, was also appointed as manager of the SA Student team and Marnus Kleinhans from Kovsies will be their coach.

The second team beat Tshwane University of Technology, University of Kwa-Zulu- Natal and University of Cape Town during the round robin and in the semi-finals they won against University of Pretoria. Unfortunately they lost in the final against the North West University, but the club is extremely proud of the players since it was the first time all of them played in a USSA tournament. They gained a lot of experience that will greatly contribute to the value they will add to the team next year.
