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.

UFS to honour past and present Cabinet ministers

2010-04-19

The University of the Free State (UFS) is going to confer honorary doctoral degrees on former Minister of Arts, Culture, Science and Technology, Dr Ben Ngubane, and the current Minister of Finance, Mr Pravin Gordhan, during the university’s autumn graduation ceremony next month.

They will receive their honorary doctorates on 18 and 19 May respectively.

“It is an honour for the UFS to confer these honorary doctorates on people like these who have made, and continue to make outstanding contributions towards the wellbeing of this beautiful country. Being associated with people of this stature signifies the direction that the UFS is taking in our quest to be a great university, one of the best in the world,” said Prof. Jonathan Jansen, the Rector and Vice-Chancellor of the UFS.

Dr Ngubane will be honoured for his immense contribution towards positioning South Africa as a major and an influential player in the development of arts, culture, science and technology internationally.

He was the first Minister of Arts, Culture, Science and Technology in the new, democratic South Africa appointed by the former President, Nelson Mandela, in 1994. He was re-appointed to lead this ministry again by former President Thabo Mbeki in 1999.

As Premier of KwaZulu-Natal from 1996 to 1999, Dr Ngubane is credited for his role in bringing about peace and reducing the political violence that ravaged the province at that time.

In 2004 he was appointed as Ambassador to Japan where he initiated, among other projects, the South Africa-Japan University Forum (SAJU).
He has been honoured for outstanding contributions to higher education and community development and holds Honorary Doctorates from the universities of Natal, Zululand, the Medical University of South Africa (Medunsa) and the Tshwane University of Technology.

He is currently the Chairperson of the SABC Board.

Minister Gordhan, on the other hand, formed an integral part of the constitutional transition of South Africa between 1991 and 1994. He chaired the Convention for a Democratic South Africa (CODESA) Management Committee – the midwife and negotiating forum for a free South Africa. He was also co-chair of the Transitional Executive Council, which was a governance structure tasked with ensuring South Africa’s transition process prior to the historic 1994 elections.

In 1994, with the dawn of a new democracy in South Africa, Mr Gordhan became a Member of Parliament and was elected as Chairperson of the Parliamentary Constitutional Committee, which oversaw the implementation of the new constitutional order. At the same time he played a leading role in drafting the present constitution of the democratic South Africa. He also led the process of formulating a new policy framework for local government transformation.

Mr Gordhan was appointed as Deputy Commissioner at the South African Revenue Service (SARS) in March 1998 after being deployed from Parliament as part of the government’s drive to transform the public service. The following year he was appointed as Commissioner for SARS with the important task, amongst others, to transform South Africa’s Customs and Revenue administration – a strategic governmental institution.

He has represented South Africa in many international undertakings, including several peacekeeping missions, as Chairperson of the Customs Workshop for the Second Global Forum on Fighting Corruption and Safe-Guarding Integrity (2001), and is often called upon to make presentations at tax seminars and customs conferences.

In 2000 he was appointed Chairperson of the Council of World Customs Organisation (WCO), based in Brussels, a position to which he was re-elected twice, thus serving from 2000 to 2006.
