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.

Ivory Coast too dependent on UN to combat violence against women

The Ivory Coast is still too dependent on the work of the United Nations (UN) to combat violence against women in the country. There is much talk about ways to address the problem, but the government is still not acting quickly and effectively enough to make a difference in the long term.

These were some of the findings by Dr Peace Medie from the University of Ghana, guest speaker during a seminar series held by the Centre for Africa Studies (CAS) on the Bloemfontein Campus of the University of the Free State on 1 October 2015.

Dr Medie presented a seminar for students in the Gender Studies programme entitled Women, Security, and Justice: a Study of the Ivorian State’s Response to Violence against Women. Prof Heidi Hudson, Head of CAS in the Faculty of the Humanities at the UFS, facilitated the seminar.

For the sake of internationalisation, the CAS often presents guest speakers from outside South Africa to address its students. In addition , Dr Medie is from Africa.

According to Dr Medie, who conducted some 150 interviews during her research over two years, there was a shortage of resources in the Ivory Coast. This is also the case in several other African countries previously involved in war.

She believes the Ivory Coast should do more to combat violence against women successfully.

She said the UN had a great influence on the way people, especially the police, were thinking about the problem - which included sexual violence against women.

“The UN will not be there forever,” Dr Medie said.

“If response depended only on the influence of an international organisation, what would happen when the UN leaves?”

According to Dr Medie, a shortage of active women’s organisations also had a role to play. She was of the opinion that these organisations should put more pressure on the government to ensure better treatment for women.

“Local organisations are needed because it is not sustainable to depend only on the work of the UN.”
