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 research sheds light on service delivery protests in South Africa

UFS research sheds light on service delivery protests in South Africa

Service delivery protests in the country have peaked during 2014, with 176 major service delivery protests staged against local government across South Africa.

A study by the University of the Free State (UFS) found that many of these protests are led by individuals who previously held key positions within the ANC and prominent community leaders. Many of these protests involved violence, and the destruction had a devastating impact on the communities involved.

This study was done by Dr Sethulego Matebesi, researcher and senior lecturer at the UFS. He focused his research on the dynamics of service delivery protests in South Africa.

Service delivery protests refer to the collective taken by a group of community members which are directed against a local municipality over poor or inadequate provision of basic services, and a wider spectrum of concerns including, for example, housing, infrastructural developments, and corruption.

These protests increased substantially from about 10 in 2004 to 111 in 2010, reaching unprecedented levels with 176 during 2014.

The causes of these protests are divided into three broad categories: systemic (maladministration, fraud, nepotism and corruption); structural (healthcare, poverty, unemployment and land issues); and governance (limited opportunities for civic participation, lack of accountability, weak leadership and the erosion of public confidence in leadership).

In his research, Dr Matebesi observed and studied protests in the Free State, Northern Cape and the North-West since 2008. He found that these protests can be divided into two groups, each with its own characteristics.

“On the one side you have highly fragmented residents’ groups that often use intimidation and violence in predominantly black communities. On the other side, there are highly structured ratepayers’ associations that primarily uses the withholding of municipal rates and taxes in predominantly white communities.”

 

Who are the typical protesters?

Dr Matebesi’s study results show that in most instances, protests in black areas are led by individuals who previously held key positions within the ANC - prominent community leaders. Generally, though, protests are supported by predominantly unemployed, young residents.

“However, judging by election results immediately after protests, the study revealed that the ANC is not losing votes over such actions.”

The study found that in the case of the structured ratepayers’ associations, the groups are led by different segments of the community, including professionals such as attorneys, accountants and even former municipal managers.

Dr Matebesi says that although many protests in black communities often turned out violent, protest leaders stated that they never planned to embark on violent protests.

“They claimed that is was often attitude (towards the protesters), reaction of the police and the lack of government’s interest in their grievances that sparked violence.”

Totally different to this is the form of peaceful protests that involves sanctioning. This requires restraint and coordination, which only a highly structured group can provide.

“The study demonstrates that the effects of service delivery protests have been tangible and visible in South Africa, with almost daily reports of violent confrontations with police, extensive damage to property, looting of businesses, and at times, the injuring or even killing of civilians. With the increase of violence, the space for building trust between the state and civil society is decreasing.”
