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.

JN Boshoff Memorial Lecture: Dr Charles Nwaila

2005-09-13

Dr Charles Nwaila, Director-General of the Free State Provincial Government and Vice-Chairperson of the University of the Free State's (UFS) Council, recently discussed the repositioning of the Free State Provincial Government to respond to the 21st century demands during the JN Boshoff Memorial Lecture at the UFS.

Free State government to focus on training of public servants

The Free State provincial government in collaboration with higher education institutions in the province is to establish the Free State Association of Public Administration to get public servants to work effectively towards the growth and development of the province.
This was announced by the Director-General of the Free State provincial government, Dr Charles Nwaila, during a lecture he delivered at the University of the Free State (UFS) in Bloemfontein this evening (Thursday 8 September 2005).

Delivering the annual JN Boshoff Memorial Lecture at the UFS, Dr Nwaila called on higher education institutions to play a critical and leading role in the re-engineering of the existing Provincial Training and Development Institute housed at the Vista campus of the University of the Free State in Bloemfontein.

Dr Nwaila was formerly the Superintendent-General (head) of the Free State Department of Education and currently serves as the Deputy Chairperson of the Council of the University of the Free State.
He said the proposed Free State Association of Public Administration is a joint initiative with the National Academy of Public Administration based in Washington DC.

“We take this opportunity to invite the University of the Free State and other knowledge based institutions to join the Provincial Government in fostering a collaborative network to help us develop our public servants,” Dr Nwaila said.
He said there were accelerating demands and a lot of pressure on limited resources, with Free Staters expecting more from their government than ever before.

“Civil servants in a developmental state are servants of the people, champions of the poor and the downtrodden and not self-serving individuals that seek only advancement on the career ladder,” Dr Nwaila said.
According to Dr Nwaila, the Free State Growth and Development Strategy has identified 11 areas that need to be addressed by the year 2014, including:

• To reduce unemployment from 38% to 20%
• To improve the functional literacy rate from 69,2% to 85%
• To stabilize the prevalence rate of HIV and AIDS and reverse the spread of the disease
• To provide a free basic service to all households
• To provide adequate infrastructure for economic growth and development

Dr Nwaila said that the Free State government will continue to follow a people-centred approach towards these development objectives with a keen sense of unity and unwavering determination to create the best of times for the Free State and all its people.
