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.

Academic and security arrangements on the Bloemfontein and South Campuses for the coming week
2016-02-28

All academic and administrative services on the Bloemfontein and South Campuses of the University of the Free State (UFS) will resume on Monday 29 February 2016.

The following academic and security arrangements have been put in place:

1.    Academic arrangements:

It is important to remember that losing an academic week has major implications for all students, particularly for first-year students, and for purposes of academic planning. The university will therefore resume its normal work on Monday 29 February 2016. Losing any additional time will severely disadvantage students, especially those who desperately need the time to catch up with lectures ahead of the coming tests and examinations. Many more students will struggle to complete the academic year if any further time is lost.

In order to ensure that the academic work of the university is not undermined, the UFS will extend this academic term by one week.
This will allow the completion of the work scheduled for last week. Given the impact that disruptions had on the emotions and concentration of many of our students, academics are requested to manage the setting and re-setting of all tests and assignments scheduled for last week with sensitivity, and to be supportive of students as they re-start their academic work.  No student should be disadvantaged in terms of tests or assignments as a result of last week’s closure. We know you would do this anyway, but this is a reminder to all staff of what we expect to be a common approach and understanding on the part of lecturers.

We rely on the leadership of the deans in the seven faculties to support staff and students in dealing with the lost time in the most appropriate manner and in supporting all efforts to refocus energies on the academic project.

As the senior leadership and management of the university, we will continue to do everything in our power to make sure that the academic programme continues uninterrupted.

2.    Security arrangements:
The Bloemfontein Campus is secure and we have more than doubled the security arrangements, with the interdict firmly in place.

The university management condemns in the strongest possible terms the violence that took place at Xerox Shimla Park on the night of Monday 22 February 2016. It also condemns the disruptions of the university that followed Monday’s event, which resulted in the suspension of academic and administrative activities on the Bloemfontein Campus. In line with the terms of the interdict - and now that we are at full capacity to secure this very large and spread-out campus - the university will act swiftly and firmly if any protests or disruption recur.

The following security arrangements are in place:
2.1  Staff and students must have their staff and student cards with them when entering the campus. Passengers in motor vehicles will have to present their cards to security personnel before access could be granted. Security personnel will check this physically by verifying that each person has a valid staff or student card.

2.2  Buses will not be allowed to enter the campus and passengers will have to be dropped off outside the gates - passengers will enter through the turnstiles with their valid access cards. Anyone without a valid access card will have to go to the Visitors Centre and present positive proof of ID (SA ID, passport or driver’s licence).

2.3  Pedestrians will have to swipe their cards at the turnstiles at the gates. Those without cards will have to enter through the Visitors Centre by presenting positive proof of ID (SA ID, passport or driver’s licence).

2.4  Visitors must report to the Visitors Centre (at Gate 5 in DF Malherbe Drive) and present positive proof of ID (SA ID, passport or driver’s licence).

2.5  Due to anticipated delays, it is advised that people allow some additional time when planning their routes to campus and to also make use of the less busy gates, such as Gate 4 (Furstenburg Road) and Gate 2 (Roosmaryn Residence).

2.6  It is advised that walkways be used, especially at night, and that pedestrians should keep to areas that are well lit.
