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.

“Indonesia and South Africa share one common trait which is diversity,” were the opening remarks of Suprapto Martosetomo, ambassador of the Embassy of Indonesia to South Africa. The ambassador drew parallels between the two republics at a public lecture hosted by the Department of Political Studies and Governance at the University of the Free State Bloemfontein Campus on 10 May 2016.

Professor Ikrar Nusa Bhakti, Research Professor in the Indonesian Institute of Sciences, presented the lecture on “Managing Political Diversities: The Indonesian Experience.” He outlined the history of Indonesia’s political and economic development, political system, and government’s policy in dealing with political and economic challenges, as well as the lessons learned from its experience.

Diversity and governance
As is South Africa, Indonesia is a ‘rainbow nation’. Being the largest country in the Southeast Asia, it boasts a population of approximately 250 million people, 300 ethnic groups, and 650 local languages. However, despite such diversity, the nation has been united behind the motto of “unity in diversity”, which was adopted when Indonesia proclaimed its independence in 1945.

Indonesia and SA also bear similarities in terms of a multiparty parliamentary system. Their current Joko Widodo and our Jacob Zuma administrations are governed by policies including anti-corruption, economic prosperity, equity and equality, quality education and healthcare, and maintenance of security.

International relations
The two countries have a long-standing relationship since 1955 when the Asia-Africa conference was held in Bandung, Indonesia. The conference represented solidarity against colonisation.

Prof Hussein Solomon, Senior Professor at the UFS Department of Political Studies and Governance, attributes Indonesia’s success as a product of education and leadership - something South Africa could learn from..“Indonesia like SA has been struggling with how to balance social diversity, democracy, and a political system. Despite this, they have managed to develop a functioning democracy and a vibrant economy. They are one of the top 20 economies in the world, and by the year 2035 will be in the top seven economies in the world, according to the Goldman Sachs, report,” he said.
