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.

“Africa Month provides an opportunity
to every student and staff member to
commemorate African unity and celebrate
our rich cultural heritage, diversity,
energy and social dynamism.”

The University of the Free State (UFS) celebrates Africa Month to commemorate African unity and praise cultural heritage, as well as to take ownership of the future of the continent. According to Prof Heidi Hudson, Director of the Centre for Africa Studies, these are reasons to take part in the festivities.

Formation of Organisation of African Unity

Africa Day is the day on which Africa observes the creation of the Organisation of African Unity (OAU) on 25 May 1963. A total of 32 independent African states attended the formation.

The OAU’s aims were to promote unity and solidarity of the African states and act as a collective voice for the continent, in order to secure Africa’s long-term economic and political future and to rid it of remaining forms of colonialism. The OAU later gave birth to the African Union, which formally replaced the OAU in July 2002.

Prof Hudson says celebrating Africa Month forms part of her centre’s institutional mandate to promote an African focus in research, teaching, as well as public debate.

“Africa Month provides an opportunity to every student and staff member to commemorate African unity and celebrate our rich cultural heritage, diversity, energy and social dynamism. Secondly, by participating we all begin to take ownership of our future on this continent.”

She adds that Africa month provides a platform for reflecting on past experiences and achievements, as well as to critically assess the failures, challenges and the lessons learnt for the sake of a better future for the continent’s people.

Working relations across the continent

The UFS has working relations with universities, embassies and consulates in African countries such as Zimbabwe, Mozambique, Botswana, Zambia, Kenya, Namibia, Nigeria, Ghana, Uganda, and Tunisia.

Five cooperation agreements exist – they are with the Botho University (Botswana), Greater Zimbabwe University, Universidad Eduardo Mondlane (Mozambique), Trinity Theological Seminary Ghana, and Namibia Evangelical Theological Seminary.

According to Kanego Mokgosi, Senior Officer at Internationalisation, there are also working relations between the university and The Council for the Development of Social Science Research in Africa, Swedish International Development Agency and The United Nations Educational, Scientific and Cultural Organization. All of these focus on research development in Africa.

Most of the international students at the UFS come from the Southern African Development Community (SADC) and the continent. It hosts 1393 students from SADC countries.

“The UFS employs SADC protocol guidelines which, among others, enjoin SADC universities to admit at least 5% of their student population from the SADC region,” says Mokgosi.

Memorial Lecture by Dr Zeleza

On 24 May 2017 the Centre for Africa Studies hosted an Africa Day Memorial Lecture by Dr Paul Tiyambe Zeleza, the Vice Chancellor (President) of the United States International University Africa, Nairobi, Kenya.

The UFS library, in collaboration with the Department of English and the Office of International Affairs, also celebrated Africa Day on 25 May 2017. They hosted a conversation on the Land Debate in South Africa, together with the launch of a book titled White Narratives: The depiction of Post-2000 Land Invasions in Zimbabwe by Prof Irikidzayi Manase. He is an Associate Professor in the Department of English.
