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.

As part of celebrating 20 years of existence, the Centre for Environmental Management at the University of the Free State (UFS) hosted a public lecture themed, ‘The Future of Environmental Management’. Mr Tshepo Moremi, Deputy Director-General of the Department of Environmental Affairs and Tourism (Free State), portfolio Environment, Conservation and Tourism, delivered this lecture.

Mr Moremi said, “The environmental performance of South Africa must be seen in the context of our history and the country’s transition. South Africa has taken the lead in being a responsible global citizen, and we also participate in international projects in this field.”

South Africa hosts one of the richest biodiversities in the world. However, the country’s economy is still very energy - and carbon intensive.

“According to the World Health Organisation, approximately 16% of all deaths and one-third of diseases in children under the age of five years are environmentally related. Inadequate sanitation and indoor pollution are key factors,” Mr Moremi said.

“Academic institutions like the UFS and the government need to take the role of equipping citizens with skills and training so that we can overcome the challenges and seize opportunities related to the environment.

“Financing mechanisms for projects related to environmental sustainability were introduced in 2011. However, we still lack skilled capacity to run these projects smoothly and to use international and national funding strategically.

“Looking forward and responding to our challenges, it is vital that we transform our economy to be an international competitor and job-creation hub, and to be sustainably climate resilient, as outlined by the National Development Plan. Minimum standards will also be put in place to regulate emissions and monitor air quality. The sustainability of society’s well-being is important to the long-term role of environmental management in boosting our socio-economic status as a nation,” Mr Moremi said.

He emphasised that it must not only be about conserving and preserving. “Our people should benefit economically and socially,” he said.

Mr Moremi encouraged the audience to defend ideas that protect our non-speaking natural resources. “Let’s all do what we can and rise to this advocacy challenge,” he added. He also expressed his gratitude towards the university for honouring him during such a celebration and for working together in advocating for environmental issues.

The Centre for Environmental Management also hosted a strategic colloquium, discussing issues such as demography, resources, climate, water, environmental management, academic pursuance, as well as curriculum and the role of professional registration which may have an influence on the nature of its programmes.
