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.

Description: Association of women judges gala dinner 2017 Tags: Association of women judges gala dinner 2017


The University of the Free State Faculty of Law, in conjunction with the International Association of Women Judges (IAWJ) South Africa Chapter, hosted a gala dinner on 25 February 2017, in Bloemfontein, to raise awareness on the development programmes that women judges in South Africa, and specifically in the Free State, are involved in.

Focus on development of upcoming legal professionals
The event was a glamorous occasion attended by high-ranking officials in the Free State judiciary and Faculty of Law staff and students. Central to the evening’s events was the launch and presentation of the IAWJ/UFS Faculty of Law bursary that was presented to Mbali Mathebula, who is enrolled for an LLM at the UFS in 2017. Judge Mahube Molemela, Judge-President of the Free State High Court, and Chancellor of the Central University of Technology (CUT), presented the bursary to Mbali, commending her for choosing a poignant research thesis that focused on the rights of children with disabilities in South Africa. Judge Molemela expressed the importance of perseverance through study, and self-development as the key to a successful career in Law.

Transformation in the legal profession still a challenge
Some of the speakers of the evening included Prof Caroline Nicholson, Dean of the Faculty of Law and programme director, Judge Soma Naidoo, who gave introductory remarks, and Judge Mandisa Maya. In her remarks, Judge Maya outlined some of the prevailing challenges that women judicial officers still face, despite decades of reforms in the legal profession. She said: “Women in the judiciary are torchbearers who inspire and empower others, especially young women, and should strive to achieve high moral standards and exceptional scholarship.”

IAWJ mentors upcoming legal professionals
Judge Naidoo said the association had, over the past seven years, partnered with universities such as UFS, University of Pretoria (UP), University of South Africa (Unisa) and University of Cape Town (UCT) to support students through social outreach programmes. She noted the involvement of corporates and other legal professionals as key to their success. Judge Naidoo said the IAWJ had been instrumental in providing training for legal professionals in areas such as trafficking in persons across the Southern African Development Community (SADC), supported by the US Embassy in Pretoria, and had held health and wellness programmes for legal officers around the country.

The gala dinner was a celebration of the successes of the association over the years, and an opportunity to reflect on the important issues that women face in the legal profession, as well as a call to action for students and young legal professionals. The proceeds from the evening will be used to further mentor and develop law students around the country.
