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.

Reitz colleagues start their own company

2014-07-01

The University of the Free State (UFS) and the five colleagues implicated in the Reitz incident of 2008 reached the final chapter in the reparation process in restoring the dignity of these colleagues on Thursday 19 June 2014.

Mr Mothibedi Molete and Mss Mankoe Naomi Phororo, Emmah Koko, Nkgapeng Adams and Sebuasengwe Mittah Ntlatseng, former cleaning staff at the UFS, are now the directors of their own cleaning company, Mamello Trading.

Furthering on its promise to assist the new-found company, the UFS has also appointed Mamello Trading as a service provider responsible for services at its South Campus.

It has been six years since the Reitz incident at the UFS and Dr Choice Makhetha, Vice-Rector: External Relations, described the journey of the past six years as a learning experience for all the stakeholders.

“This journey continues as there is still work to be done, but every milestone achieved, deserves a celebration like today’s,” Dr Makhetha said.

In 2010 the UFS signed a deed of settlement with the colleagues which committed the UFS to help them establish a cleaning company. This was followed by a reconciliation ceremony in 2011.

In 2012 the UFS assisted with the registration of the company Mamello Trading.

Dr Makhetha explained that in 2013 the UFS assisted in training the new directors and mentoring them for 12 months.

Earlier this year, Mamello Trading signed a cleaning contract of four years with the UFS. Three of the directors’ daughters also received bursaries and are currently studying at the UFS.

Advocate Mohamed Ameermia, Commissioner at the Human Rights Commission, congratulated the management of the UFS on the reparation and reconciliation process they followed in restoring the dignity of the five colleagues.

The directors of Mamello Trading each had a special message of their journey and thanks. Their messages were as follows:

Rebecca Adams – After the video was exposed, I was hurt and was psychologically affected. By offering their apologies to us, the four students indicated that what they had done was a mistake. As a parent, when a child apologises you must accept that apology.
Emma Koko – I was shocked after the video was shown in public. I had a mother-child-like relationship with one of the students and that video tarnished my image as a human being. During the time of reconciliation these students showed remorse for what they had done.
David Molete – I was devastated, hurt and fearful to meet people. I ended up at a psychiatric hospital and attended counseling services which helped me to heal. The students apologised and I accepted because they were sincere.
Mittah Ntlaseng – The video impacted negatively on my dignity. The UFS assisted us with visits to psychologists. Now I feel I am a business owner and it is an opportunity for me to rebuild my self-esteem.

Naomi Phororo – Mamello Trading is a business venture which is going to bring changes to our lives and families. The training I have received has enabled me to know how to manage the business.
