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.

SRC elections: A first for UFS main campus

2005-08-14

Students on the main campus of the of the University of the Free State (UFS) will this week for the first time vote for the Student Representative Council (SRC) using two voting systems: proportional representation (PR) and first-past-the-post.

According to the Vice-Rector, Student Affairs, Dr Ezekiel Moraka, this year’s elections are a milestone for the UFS as it will be the first time that the main campus SRC will be elected according to the amended SRC constitution, which was approved by the UFS Council in June 2005.

“It is also a major breakthrough for student governance and transformation of the UFS main campus and constitutes a legitimate basis for the democratic participation of all students at the UFS main campus in the governance of the university,” said Dr Moraka.

The amended constitution of the main campus SRC determines that nine of the 18 SRC members must be elected by means of proportional representation and nine on the basis of an individual, first-past-the-post election.

According to Dr Moraka, the introduction of the proportional representation system follows earlier calls by some student formations, notably Sasco and the ANC Youth League, for such a system to be introduced at the UFS main campus in Bloemfontein.

The new main campus SRC constitution is the result of consensus reached during a lengthy negotiation process involving diverse student formations such as Sasco, the ANC Youth League, the Young Communist League, the ACDP, HEREXVII, KovsieAlliance, as well as the democratically elected SRC members of the main campus.

“Independent persons such as Mr Jack Klaas and Mr Kobus van Loggerenberg, a former SRC President, facilitated the negotiation process,” said Dr Moraka.

Students on the main campus in Bloemfontein will vote for a new SRC on Monday 15 August 2005.

SRC elections will also take place on the other two campuses of the UFS, which have their own SRC structures.

Students on the UFS-Vista campus in Bloemfontein will vote for a new SRC on Monday 15 August 2005 and Tuesday 16 August 2005.

At the Qwaqwa campus of the UFS, students will vote for a new SRC on Friday 26 August 2005.

The election processes on all three campuses will be closely monitored by independent electoral bodies.

After the three campuses have elected their respective SRCs a central SRC will be constituted. The central SRC will have 12 members made up of delegates of the three campus SRCs, including the presidents of these three SRCs. The main campus will have five representatives, the Qwaqwa campus will have four representatives and the Vista campus will have three representatives.

Main campus voting schedule:
Monday 15 August 2005 from 07:00-21:00. Ten voting stations will be set up across the campus. The results will be announced on Tuesday 16 August 2005.

Vista campus voting schedule:
Monday 15 August 2005 and Tuesday 16 August 2005 from 09:00-18:00 in the administration building. The results will be announced on Wednesday 17 August 2005.

Qwaqwa campus voting schedule:
Friday 26 August 2005 from 09:00-18:00 in the Senate Hall. If there is no objection to the final results, it will be announced on the same day.
