UFS makes groundbreaking advance in temperature measurement technology, fulfilling Vision 130

10 June 2024 | Story Precious Shamase | Photo Supplied

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.

First doctorate in Thoracic Surgery in Africa awarded

2009-05-12

The University of the Free State (UFS) has become the first university in Africa to award a Ph.D. degree in Thoracic Surgery. The degree was conferred on Prof. Anthony Linegar from the university’s Department of Cardiothoracic Surgery during its recent graduation ceremony.

Thoracic surgery is a challenging subspecialty of cardiothoracic surgery. It began in South Africa in the 1940s and is a broad medico-surgical specialist discipline that involves the diagnosis, operative and peri-operative treatment of acquired and congenital non-cardiac ailments of the chest.

Prof. Linegar became the first academic to conduct a mixed methods analysis of this surgical specialty, which included a systematic review of all the research done in this field in South Africa. The title of his thesis is A Model for the Development of Thoracic Surgery in Central South Africa. The research was based on the hypothesis of a performance gap between the burden of disease in the community and the actual service provision. It makes use of systems theory and project management concepts to develop a model aimed at the development of thoracic surgery.

The research proved that there is a significant under provision of clinical services in thoracic surgery. This was quantified to a factor of 20 times less than should be the case, in diseases such as lung and oesophagus cancer. According to Prof. Linegar, there are multiple reasons for this. Listed amongst these reasons is the fact that thoracic surgery is not part of the undergraduate education in medical training. There tends to be a low level of awareness amongst clinicians as to what the thoracic surgeon offers their patients. The diagnostic and referral patterns in primary and secondary health facilities, where diseases must be picked up and referred early, are not functioning well in this regard. In addition, relatively few cardiothoracic surgeons express an interest in thoracic surgery.

Prof. Linegar’s model is named the ATLAS Mode, which is an acronym for the Advancement of Thoracic Surgery through Analysis and Strategic Planning. It includes the raising of awareness of the role of the specialist thoracic surgeon in the treatment of patients with thoracic diseases as part of the solution to the problem. Furthermore, it aims to develop an accessible and sustainable specialist service that adequately provides for the needs of the community, and that is appropriately represented in health administration circles.

His promoters were Prof. Gert van Zyl, Head of the School of Medicine at the UFS, Prof. Peter Goldstraw, from the Imperial College of London, United Kingdom (UK) and Prof. Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS.

Prof. Linegar has been with the UFS since 2004, is a graduate from Stellenbosch University in 1984 and completed his postgraduate training in Cardiothoracic Surgery at the University of Cape Town. He was granted a Fellowship in Thoracic Surgery at the Royal Brompton Hospital in London, UK and has since held consultant positions at the UFS, Stellenbosch University and in private practice. He has been involved in registrar training since returning from the UK in 1994 and has extensive experience in intensive care medicine. He has published widely, has presented papers at many international conferences, has been invited as a speaker on many occasions and has won awards for best presentation on three occasions.
