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.

South African born biophysicist and Nobel Prize-winner in Chemistry, Prof Michael Levitt, paid a visit to the University of the Free Sate (UFS) as part of the Academy of Science of South Africa’s (ASSAf) Distinguished Visiting Scholars’ Programme. 

Early this week the professor in structural biology at Stanford University in the US presented a captivating lecture on the Bloemfontein Campus on his lifetime’s work that earned him the Nobel Prize in 2013. His lecture launched the UFS Vice-Chancellor’s Prestige Lecture series, aimed at knowledge sharing within, and beyond our university boundaries. 

Prof Levitt was one of the first researchers to conduct molecular dynamics simulations of DNA and proteins and developed the first software for this purpose. He received the prize for Chemistry, together with Martin Karplus and Arieh Warshel, “for the development of multiscale models for complex chemical systems”.

Attending the lecture were members of UFS management, academic staff from a range of faculties and other universities as well as young researchers. “Multiscale modelling is very much based on something that makes common sense,” Prof Levitt explained. “And that is to makes things as simple as possible, but not simpler. Everything needs to have the right level of simplicity, that is not too simple, but not too complicated.”  

An incredible mind
Prof Levitt enrolled for applied mathematics at the University of Pretoria at the age of 15. He visited his uncle and aunt in London after his first-year exams, and decided to stay on because they had a television, he claims. A series on molecular biology broadcast on BBC, sparked an interest that would lead Prof Levitt via Israel, and Cambridge, to the Nobel Prize stage – all of which turned out to be vital building blocks for his research career. 

Technology to the rescue
The first small protein model that Prof Levitt built was the size of a room. But that exercise led to the birth of multiscale modelling of macromolecules. For the man on the street, that translates to computerised models used to simulate protein action, and reaction. With some adaptations, the effect of medication can be simulated on human protein in a virtual world. 

“I was lucky to stand on the shoulder of giants,” he says about his accomplishments, and urges the young to be good and kind. “Be passionate about what you do, be persistent, and be original,” he advised.
