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.

UFS finances are fundamentally sound

2007-12-01

The finances of the University of the Free State (UFS) remain fundamentally sound and a higher than expected surplus of about R26 million was achieved in the 2007 budget.

This announcement was made last week during the last meeting of the UFS Council by Prof. Frederick Fourie, Rector and Vice-Chancellor.

“Up to now, we could finance the considerable investments in the infrastructure from discretionary funds, in spite of the fact that Council granted us permission during 2005/06 to take up a loan of R50 million for this purpose,” said Prof. Fourie.

The higher than expected surplus of about R26 million will be used among other things for the financing of infrastructure in order to further postpone the taking up of a loan.

In support of the drive to reposition the UFS nationally as a university that is successfully integrating excellence and diversity, R5 million will be made available from the surplus for this purpose.

The Council also approved the following allocations for 2008 for the key strategic pillars of a good practice budget for the university:

Information sources: R21,1 million
IT infrastructure: R3,5 million
Replacing expensive equipment: R7,05 million
Research: R18,1 million
Capital expenditure: R28,2 million
Maintenance capital assets: R18,2 million
Reserves: R6,3 million
Personal computers for the computer laboratory: R3,5 million

For the Qwaqwa Campus R2,5 million has been set aside for these issues.

In terms of strategic priorities R8 million was allocated for the academic clusters, R2 million for equitability, diversity and redress and R6 million for equity.

The projected income for 2008 will be R849 million, while the projected expenditure, excluding transfers, will be R694 million.

“Council further approved that discretionary strategic funds be largely voted to the further upgrading of the physical infrastructure, especially the Chemistry Building, the computer laboratory building, examination venues and the Joolkol,” said Prof. Fourie.

According to Prof. Fourie, funds have been reserved for the development of the academic clusters, as well as the continuation and acceleration of the transformation programme of the UFS.

“We have also managed to revise the conditions of employment of contract appointments and align it with the latest labour practices. The phasing in of the fringe benefits of this specific group of staff members will commence in 2008,” said Prof. Fourie.

Given the dependence of the income of the UFS on student numbers, a task team was formed last year to investigate the continued financial sustainability of the UFS. The core of this task team’s recommendations is:

to increase the third income stream by using the academic clusters as the main strategy; and to apply strategies such as the recruitment and extension of the postgraduate and foreign student corps, increase the income from donations and fundraising, etc.
