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.

Premiere of the documentary on King Moshoeshoe - Address by the Rector
2004-10-14

Address by the rector and vice-chancellor of the University of the Free State, prof Frederick Fourie, at the premiere of the documentary on King Moshoeshoe, Wednesday 13 October 2004

It is indeed a privilege to welcome you at this key event in the Centenary celebrations of the University of the Free State.

We are simultaneously celebrating 100 years of scholarship with 10 years of democracy

Today is a very important day with great significance for the University. This Centenary is not merely a celebration of an institution of a certain age. It is a key event in this particular phase of our history, in our transformation as an institution of higher learning, in taking the creation of a high-quality, equitable, non-racial, non-sexist, multicultural and multilingual university seriously.

This is about building something new out of the old, of creating new institutional cultures and values from diverse traditions.

It is about learning together - as an higher education institution - about who we are where we come from – to decide where we are going.

It is about merging the age-old tradition of the university, of the academic gown, with the Basotho blanket, the symbol of community engagement.

Then why is it important that we remember Moshoeshoe, where does he fit into our history?

In the Free State province, where large numbers of Basotho and Afrikaners (and others) now live together, a new post-apartheid society is being built in the 21st century.

The challenge is similar to that faced by Moshoeshoe 150 years ago. As you will see tonight, he did a remarkable thing in forging a new nation out of a fragmented society. He also created a remarkable spirit of reconciliation and a remarkable style of leadership.

Not all people in South Africa know the history of Moshoeshoe. Many Basotho – but not all – are well versed in the history of Moshoeshoe, and his name is honoured in many a street, town and township. Many white people know very little of him, or have a very constrained or even biased view of his role and legacy. In Africa and the world, he his much less known than, for instance, Shaka. (In Lesotho, obviously, he is widely recognised and praised.)

We already benefit from his legacy: the people of the Free State share a tradition of moderation and reconciliation rather than one of aggression and domination.

With Moshoeshoe, together with Afrikaner leaders and reconciliators such as President MT Steyn and Christiaan de Wet, we have much to be thankful for.

Our challenge is take this legacy further: to forge a new society in which different cultural, language and racial groups – Basotho, Afrikaners and others – will all feel truly at home.

Bit by bit, on school grounds, on university campuses, in each town and city, people must shape the values and principles that will mould this new non-racial, multicultural and multilingual society.

A shared sense of history, shared stories and shared heroes are important elements in such a process.

Through this documentary film about King Moshoeshoe, the UFS commits itself to developing a shared appreciation of the history of this country and to the establishment of the Free State Province as a model of reconciliation and nation-building.

Moshoeshoe is also a strong common element, and binding factor, in the relationship between South Africa / the Free State, and its neighbour, Lesotho.

For the University of the Free State this also is an integral part of real transformation – of creating a new unity amidst our diversity.

Transformation has so many aspects: whilst the composition of our student and staff populations have been changing, many other things change at the same time: new curricula, new research, new community service learning projects.

In also includes creation of new values, new (shared) histories, new (shared) heroes.

It includes the incorporation of the Qwaqwa campus, which serves a region where so many of the children of Moshoeshoe live, including her majesty Queen Mopeli.

We see in Moshoeshoe a model of African leadership – of reconciliation and nation-building – that can have a significant impact in South Africa and Africa as a whole.

We also find in the legacy of King Moshoeshoe the possibility of an “founding philosophy”, or “defining philosophy”, for the African renaissance.

To develop this philosophy, we must gain a deeper understanding of what really happened there, of his role, of his leadership.

Therefore the University of the Free State will encourage and support further research into the history, politics and sociology of the Moshoeshoe period, including his leadership style.

We hope to do this in partnership with National University of Lesotho.

The Moshoeshoe documentary is one element of a long-term project of the UFS. The other elements of the project that we are investigating are possible PhD-level research; a possible annual Moshoeshoe memorial lecture on African leadership; and then possible schools projects and other ways and symbols of honouring him.

It is my sincere wish that all communities of the Free State and of South Africa will be able to identify with the central themes of this documentary, and develop a shared appreciation for leaders such as King Moshoeshoe and the legacy of peace, reconciliation and nation-building that they have left us.
