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.

“The first 1 000 days, from conception to two years, is a critical time to ensure that the early environment is optimal to guarantee the best outcomes,” Prof Corinna Walsh, Professor in the Department of Nutrition and Dietetics at the University of Free State (UFS), said. She delivered her inaugural lecture on Nutrition in Transition on 30 October 2017. 

During her lecture, Prof Walsh explained how an unfavourable early environment impacts on the health and well-being of both children and adults. She gave an overview of the prevalence of hunger and food insecurity in the Free State, and described the shift that has occurred from healthier traditional diets to more unhealthy Western diets accompanied by sedentary lifestyles. These patterns are closely linked to the triple burden of malnutrition, including undernutrition, micro-nutrient malnutrition, and obesity. Finally, Prof Walsh highlighted the double burden of disease, focusing on chronic lifestyle diseases on the one hand, and infectious diseases such as HIV/AIDS and TB on the other hand.

“Preparing for this lecture has given me the opportunity to reflect on the almost thirty years of my research journey, a process that I thoroughly enjoyed,” said Prof Walsh.

“It was a privilege to share the work of my research team with fellow colleagues as well as with family and friends,” she said. Prof Walsh is a National Research Foundation C-rated researcher and also served on the Board of the Medical Research Council from 2005 to 2010.

Foundations for health, growth established early
The first 1 000-day window focuses on the time between conception and the second birthday. “This is a critical period for growth and development,” Prof Walsh said. It is a unique period, as the foundations for health, growth, and neuro-development are established. It also focused on the implications of malnutrition, which is the biggest risk factor contributing to the global burden of disease.


Research identifies burden of disease
Her research has made a considerable contribution to identifying the burden of disease in the Free State. “It focuses on both malnutrition and infectious diseases such as HIV and TB on the one hand, and chronic lifestyle diseases such as obesity, diabetes, and hypertension on the other,” she said. The research team have also implemented a number of interventions to address these challenges, including programmes that have assessed the impact of nutrition-education programmes, household food gardens, and nutrition supplementation.
