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.

National Human Trafficking Resource Line a victim-centred approach to combating crime

As a response to the rising number of human trafficking cases in South Africa and around the world, key role players in various fields have pulled together to come up with workable solutions on how to stop the crime and assist victims. Some of the work being done by NGOs and law enforcement agencies has been supported by insights from research conducted in communities and by academic institutions. According to Prof Beatri Kruger, Adjunct Professor of Law in the Faculty of Law at the University of the Free State and experienced researcher in human trafficking, support for victims has grown in leaps and bounds with the help of the latest technology. More and better quality information can be collected to strengthen efforts of combating the crime,” she said.

One such technological development is the national Human Trafficking Resource Line, which provides various services, including information on trafficking activities, assistance to agencies working with victims of trafficking in persons (TIP), creating a network from which data can be collected, analysed, and activities tracked, in order to ensure the best service to victims.

The resource line connects callers, often victims of TIP or anonymous tippers, to service providers in social services, law enforcement, places of safety, medical facilities, and government agencies, especially during emergencies. 

Resource line a helping hand to victims

The resource line was established in 2016 and has replaced the previous helpline. This line provides more services and resources than just a helpline. Through partnerships, it works to strengthen local and national structures that can assist victims over the phone. 

Call specialists are trained by Polaris, an American company using international standards and protocols. The call specialists are available 24/7 to take reports of human trafficking confidentially and anonymously. They put victims in touch with service providers for health screening, counselling, and repatriation if they are from another country, and also assist with case management.

Empowering service providers is the key to success

Support for service providers such as NGOs, safe houses, and government departments in the network is in the form of skills training programmes for staff, and a referral system in various provinces around the country. There are good referral partners in each province, as well as provincial coordinators ensuring accountability regarding cases, mobilising services for victims, and coordinating the referrals and response.  

To strengthen the network further, services provided in each province are being standardised to ensure that the right people are contacted when handling cases, and that key stakeholders in each province are used. The strength of the provincial provider network is key to offering victims of human trafficking the services they need.

Human trafficking is a crime that permeates multiple academic disciplines and professions. Therefore, information collected from victims through such a helpline and collated by agencies, will assist academic institutions such as the UFS in furthering their research, while strengthening the content of academic programmes in fields such as law, law enforcement, social sciences, health sciences, and international relations.

The number to call for reporting or providing tips on TIP-related crimes and activities, is 0800 222 777.
