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.

Dean of the Faculty of Law delivers farewell lecture
2013-12-04

Prof Johan Henning, Dean of the Faculty of Law at the University of the Free State (UFS), delivered his farewell lecture during an event attended by distinguished guests from law circles in Bloemfontein, staff from the faculty, as well as family and friends.

The topic of his farewell lecture was: From leonine to universal partnerships. This theme was also the focus of his inaugural lecture and his later research. “It was a privilege to have been part of the development of universal partnership law,” Prof Henning said.

During the event, Prof Henning was honoured by colleagues, as well as members of the law profession, for his contribution to the academy. Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, thanked Prof Henning for his part in preparing a new generation of academics for the future.

Prof Elizabeth Snyman-Van Deventer from the Department of Mercantile Law, described Prof Henning as someone with an excellent knowledge of history, especially with regard to the Anglo-Boer War and the World Wars. “He is also one of only a few academics of which four postgraduate students became professors. He has lots of empathy with other people and, despite his long list of academic achievements, he is a very humble man. Two of his outstanding characteristics are his humanity and his modesty,” said Prof Snyman-Van Deventer.

Judge Faan Hancke, former chairperson of the UFS Council and Judge of the Supreme Court, said Prof Henning is a multi-faceted person. “He is an incredible academic who has published widely and is the author of several textbooks. He is also editor of a number of journals and serves on the editorial board of several publications. I have great admiration for his academic excellence and his absolute knowledge of partnership law. He is the best in South Africa and is also highly regarded internationally in this aspect of the law (he was, among others, director of the Centre for Comparative Partnership and Company Law at the Institute of Advanced Legal Studies of the University of London). He is the ideal academic, who has achieved the highest rating in his specialist field of Mercantile Law in South Africa, namely a B1 received in 2012, and he is an excellent dean,” Judge Hancke said.

Prof Henning has a long association with the UFS. In 1968 he reported as a first-year student. Later, in 1974, he was appointed in the Department of Mercantile Law on a temporary basis. In 1998 he was appointed as Dean of the Faculty of Law. Some of the highlights in his career include his appointment as African representative of CIDOEC, Jesus College, Cambridge, and becoming the first South African being awarded an honorary fellowship to the Society of Advanced Legal Studies in Brittain, as well as the American Order of the Coif.

Prof Henning will continue his partnership with the university in 2014, acting as dean and continuing his research.
