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 awards centenary bonuses to staff

2004-11-25

The University of the Free State (UFS) will award a special Centenary bonus of R3000 (three thousand rand) to all qualifying staff in December 2004 .

As far as general salary increases for 2005 are concerned, plus an inflation- based linked salary increase adjustment of 1,4 percent and a further 4,6 percent salary increase as a final dividend from the financial turn-around strategy that began in 2000, will be instituted .

The final percentage salary increase is dependent on whether the expected government subsidy, of which the UFS must still receive notification from the Department of Education, is received.
, if the expected government subsidy realizes .
In addition, the salaries of service workers in low remuneration groups, as well as full professors have been adjusted retroactively to 1 January 2004. This restructuring was agreed upon to address market-related backlogs for these two groups , who display the biggest backlog relative to comparable institutions . A similar professional bench-marking exercise for support service staff has not been finalised.

This agreement was signed on Wednesday 24 November 2004 between the UFS Council and the UVPERSU-NEHAWU Joint Forum regarding salary negotiations for 2005.

“With this Centenary bonus and the significant above-inflation salary increase payment the UFS wants to pay recogni se tion to the sterling role that staff

have played in a difficult period of transition and fast growth and the contributions that they made to promote excellence at the UFS to a

university of excellence,” said Prof Frederick Fourie, Rector and Vice-

Chancellor of the UFS.

He said that the extra payment of this final 4,6 percent increase due to benefit from the financial turn-around strategy means that in real terms average salaries at the UFS had increased over the past 3 to 4 years by well over more that the 15 percent target that was set initially.

According to Prof Fourie all staff members who were in the employ of the UFS on UFS conditions of service on 15 November 2004 and who assumed duties before 1 October 2004, will qualify for the bonus. The same criteria will apply as for the 2004 bonuses.

However, there are some exceptions who do not qualify for the bonus eg learning facilitators, professors extraordinary, affiliated lecturers, departmental assistants, laboratory assistants, student help, all staff appointed for less than 20 hours per week, persons who are paid on a claims basis etc.

“Although the UFS’s actual subsidy amount is not yet known, an increase of 6,6 % in the total remuneration costs was budgeted for in the budget serving before the Executive Management and Council. It was further agreed with the UVPERSU-NEHAWU Joint Forum that the first 6 % increase will be used as general pensionable salary adjustment with implementation date 1 January 2005,” said Prof Fourie.

According to Prof Fourie the agreement also applies to all staff members of the Qwaqwa and Vista campuses whose conditions of service are already aligned with those of the main campus.
