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.

UFS academic delivers inaugural lecture on challenges confronting political science in the 21st century

This week Prof. Hussein Solomon, Senior Professor in the Department of Political Studies and Governance delivered his inaugural lecture on the Bloemfontein Campus of the University of the Free State (UFS).

In his lecture, “Challenges confronting political science in the 21st century, A South African perspective”, Prof. Solomon explored five challenges to academic political science in general and to South African political scientists in particular.

The challenges include the need to localise international relations theory with an emphasis on the emancipatory dimensions; exploring the nexus between technology and politics; incorporating political anthropology into mainstream political science syllabi; rising to the challenge of governing Africa’s cities; and the dangers of over-specialisation in an era that demands the use of a broader academic lens.

According to Prof. Solomon, political science has come a long way from those heady days in 1950 when Lasswell could confidently state that politics was about who gets what, when and how.

“Indeed, the world of 2012 scarcely resembles the world of 1950. Immanuel Wallerstein was correct in his assessment that the modern world system is coming to an end. As political scientists, we need to interrogate our existing knowledge constructs in relation to this rapidly changing reality. We need to indigenise international relations theory and emphasise creating an emancipatory and counter-hegemonic discourse.

We need to explore the nexus between technology and politics to deepen our democracy by empowering the margins in our societies. We need to embrace political anthropology as we strive to understand non-Western forms of governance. We need to use these understandings of traditional societies as we create hybrid forms of urban governance that stress inclusivity as we overcome the politics of identity and difference. We need to heed the call of De Tocqueville and create a new political science to understand the new times by supplementing disciplinary insights with those from other disciplines. In doing so, political science will once more regain its relevance to humanity in the twenty-first century,” Prof. Solomon said.
