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.

Qwaqwa Campus’s Teaching and Learning Champs scoop up award

Action research to improve classroom practice and student success rates, recently received a boost when the Qwaqwa Campus’s Teaching and Learning (TL) Champions were honoured with the prestigious UFS Vice-Chancellor’s Team Award. The award was in recognition of the team’s efforts to enhance professional development and was accompanied by a R50 000 prize that will be utilised to further encourage and develop a scholarly culture on the Qwaqwa Campus.

“An active learning community has developed over the past four years, which led to the creation of a scholarly forum for sharing problems, experiences and new knowledge”, revealed Dr Elize Smuts, who has been the pillar of strength in the development of TL Champs.

“This”, Dr Smuts said, “has continuously motivated the group to persevere in challenging and often under-resourced circumstances.”

 “Over a four-year period, 44 projects were undertaken, many with great success. Thirteen scholars participated in a pilot of CLASSE (Classroom Assessment of Student Engagement) in 2013. This survey, contextualised by staff from the Centre for Teaching and Learning, was a first in South Africa,” said Dr Smuts.

“The team undertook extensive literature reviews and attended numerous workshops on principles and practices of good teaching, research and writing. The two summarising booklets they prepared from two publications (How Learning Works: 7 Research-based Principles for Smart Teaching and Student Engagement Techniques) in 2013, will serve as guides and inspiration for the larger academic community of the UFS for many years.”

Since the formation of this team, TL scholars have presented 25 papers at 12 national and two international conferences.

“Taking into consideration that it is not easy to get an abstract accepted for presentation, these are impressive achievements,” Dr Smuts said.

“Some of the immediate results of scholars engaged in this project, include improved student success rates averaging 20% compared to only 8% improvement by academics who are not part of the project.”
 
“In 2013, one TL scholar reported student success rates that increased by 29%; another reported 80% on average; and another reported an increase from 65% to 95% in a class bigger than previous years.”

In congratulating the team, Centre for Teaching and Learning’s (CTL) Prof Annette Wilkinson said that she was very proud of the team.
 
“The team’s dedication and growth in scholarly practice – amidst challenging circumstances – are in my mind, the outstanding features of the project. I am very proud of the entire team”, said Prof Wilkinson.

The two presentations at international conferences were delivered by Ms Lea Koenig at the 32nd Annual Conference on the First-Year-Experience in Orlando, Florida and by Dr Elize Smuts in North Carolina. Both of these were presented in 2013.
