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.

Professor’s research part of major global programme
2011-04-04

 

Prof. Zakkie Pretorius, professor in Plant Pathology in the Department of Plant Sciences at our university

Research by Zakkie Pretorius, professor in Plant Pathology in the Department of Plant Sciences at our university, has become part of Phase II of a mayor global project to combat deadly strains of a wheat pathogen that poses a threat to global food security.

Prof. Pretorius focuses on the identification of resistance in wheat to the stem rust disease and will assist breeders and geneticists in the accurate phenotyping of international breeding lines and mapping populations. In addition, Prof. Pretorius will support scientists from Africa with critical skills development through training programmes. During Phase I, which ends in 2011, he was involved in pathogen surveillance in Southern Africa and South Asia.
 
The Department of International Development (DFID) in the United Kingdom and the Bill and Melinda Gates Foundation will invest $40 million over the next five years in the global project led by the Cornell University. The project is aimed at combating deadly strains of Ug99, an evolving wheat pathogen that is a dangerous threat to global food security, especially in the poorest nations. 
 
The Cornell University said in a statement, the grant made to the Durable Rust Resistance in Wheat (DRRW) project at Cornell will support efforts to identify new stem-rust resistant genes in wheat, improve surveillance, and multiply and distribute rust-resistant wheat seed to farmers and their families.
 
Researchers worldwide will be able to play an increasingly vital role in protecting wheat fields from dangerous new forms of stem rust, particularly in countries whose people can ill afford the economic impact of damage to this vital crop.
 
The Ug99 strain was discovered in Kenya in 1998, but are now also threatening major wheat-growing areas of Southern and Eastern Africa, the Central Asian Republics, the Caucasus, the Indian subcontinent, South America, Australia and North America.
 
Prof. Pretorius was responsible for the first description of this strain in 1999.
 
Among Cornell’s partners are national research centres in Kenya and Ethiopia, and scientists at two international agricultural research centres that focus on wheat, the Mexico-based International Maize and Wheat Improvement Center (known by its Spanish acronym as CIMMYT), and the International Center  for Agricultural Research in the Dry Areas (ICARDA), in Syria. Advanced research laboratories in the United States, Canada, China, Australia, Denmark and South Africa also collaborate on the project. The DRRW project now involves more than 20 leading universities and research institutes throughout the world, and scientists and farmers from more than 40 countries.
