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.

“Mother of African Freedom, heroine, teacher, unifier and true revolutionary.”

That is how dignitaries such as President Jacob Zuma, African Union (AU) Commission Chairperson Dr Nkosazana Dlamini Zuma, Basic Education Minister Angie Motshekga and others described Charlotte Maxeke, the woman they came to celebrate at the University of the Free State on 4 August 2012.

President Zuma honoured the life of the ANC Women’s League stalwart in delivering the fifth annual Charlotte Maxeke Memorial Lecture. The event officially kicked off the national Women’s Month celebrations and thousands of people made their way to the Bloemfontein Campus to listen to the President’s address.

President Zuma told the audience in the Callie Human Centre that women activism had not started with the 1956 march to the Union Buildings – it began much earlier. He spoke about Charlotte Maxeke’s leading role in the landmark 1913 march against pass laws in Bloemfontein and said this had inspired bravery and enthusiasm in the hearts of many in the struggle.

“As a collective, we must emulate the contribution of Mama Maxeke. In her honour, we must continue to open new paths for women, enable them to break new ground in leadership." President Zuma said Charlotte Maxeke, who believed a woman’s place was everywhere, had to be smiling with regard to Dr Dlamini Zuma’s appointment as Chairperson of the AU Commission.

In her speech, Dr Dlamini Zuma encouraged women to embrace the African Decade of Women, saying it was their responsibility to define and implement the changes they want to see. “We should define for ourselves what this decade means, define that we want to do, the role we want to play and achieve during this decade.”
