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.

Shortage of quantity surveyors discussed at UFS

Shortage of quantity surveyors discussed at UFS

“The South African building industry is experiencing an unprecedented high level of economic growth and prosperity. This is causing a definite shortage of registered quantity surveyors,” said Mr Egon Wortmann, Director of the Association of South African Quantity Surveyors(ASAQS) during the association’s recent visit to the Department of Quantity Surveying and Construction Management at the University of the Free State (UFS).

“This shortage is especially noticeable in local and national governments where unqualified and inexperienced staff, consultants and/or facilitators are now appointed,” said Mr Wortmann.

In doing so, the authorities that have adopted this approach are according to Mr Wortmann actually acting illegally and are not in compliance with the legal and statutory requirements of South Africa. “These unprofessional practices are unproductive, it leads to frustration and is strongly condemned by the ASAQS,” he said.

“The service delivery of these unqualified and unregistered service providers is often sub standard and does not comply to the legal requirements of the profession. It may also result in the tarnishing of the image and high professional standards set by the quantity surveying profession,” said Mr Wortmann.

“Universities offering programmes in quantity-surveying and construction management are also negatively affected by the high levels of activity in the building environment. Suitable lecturing staff are leaving the academic institutions as they are attracted to better opportunities being offered in the building industry. The ability of the tertiary institutions to attract young academics, to train them and to keep them in the longer term, is therefore almost impossible”, said Prof Basie Verster, head of the Department of Quantity Surveying and Construction Management at the UFS and representative of the Free State on the ASAQS.

According to Prof Verster the UFS supplies more than its quota of qualified quantity surveyors to the South African building industry. “Although more than 460 students are registered in construction related programmes at the UFS, we are as the ASAQS’s concerned about the shortage of students that can enter the construction industry. In our case, we are experiencing a shortage in black female students,” he said.

“Of the 460 postgraduate students, 38% are black of which 20% are female students. Graduates do also not necessarily stay in the country. As the UFS’s programmes are accredited overseas, a lot of our students leave the country for working opportunities elsewhere,” said Prof Verster.

Mr Patrick Waterson, President of the ASAQS, appealed to quantity surveyors to, when they are approached, consider academic careers or to make themselves available to lecture on a part time basis. “I also appeal to quantity-surveying practices, construction companies and developers to consider taking part in training activities,” he said.

The ASAQS has over the years developed a proud tradition within the quantity-surveying profession. Consequently membership of this organisation is a sought after goal for many members within the building environment. International agreements with various countries are also in place whereby it is mutually agreed that local as well as overseas qualifications are mutually acceptable on a reciprocal basis.

A more recent addition to the list of agreements is the reciprocity agreement entered into with the Royal Institution of Chartered Surveyors which makes it possible for South African based quantity surveyors to practice in over 120 countries worldwide.
