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.

Is Al-Qaeda operating in South Africa?
2014-09-29

 
Our Department of Political Studies and Governance recently hosted a seminar with investigative journalist De Wet Potgieter – author of the book, ‘Black Widow White Widow’.During the seminar, Potgieter reflected on the research he has conducted for the book, revealing the unsettling presence of Al-Qaeda in South Africa.

The ‘White Widow’ in the book’s title refers to Samantha Lewthwaite, a British woman who was found in South Africa with a fraudulent passport. She was later linked to the Westgate shopping mall attack which took place in Nairobi, Kenya on 21 September 2013. In this mass shooting at least 67 people died and over 175 people were wounded. The Islamist group al-Shabaab – which is also linked to Al-Qaeda – claimed responsibility for the incident.

In contrast, the ‘Black Widow’ is the disclosed identity of an Afrikaans-speaking self-styled spy, who after being widowed became a counter-terrorist operative.

Potgieter’s book divulges details of Al-Qaeda paramilitary and urban warfare training on a secluded farm in the Little Karoo and reveals details of the support they receive from various local extremist groups. Potgieter’s investigation spans across two years and suggests possible future attacks from, or on, South African soil.

“South Africa plays a role in the bigger picture for Al-Qaeda Islamic terrorism,” Potgieter said. “For instance, the Navy Seal team who killed Bin Laden found reports pointing to active Al-Qaeda/Islamist presence in South Africa. South Africans need to know we are under siege by a small, well-trained Al Qaeda terrorist cell. Yet, operations – of which I know, but cannot disclose much – are also underway to contain these matters,” Potgieter added.

Potgieter’s sources suggest that Al-Qaeda has been active in South Africa since the 2010 FIFA World Cup already. The South African government seems to turn a blind eye, though, despite CIA and MI6 requests and enquiries on the matter.
