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.

Up to 60% of students do not have enough to eat
2013-11-15

 

15 November 2013

A report of the University of the Free State has revealed the shocking statistics that almost two-thirds of the students at the university don’t have enough money to buy food, and suffer from hunger during terms.

The study, conducted internally by the university’s Department of Nutrition and Dietetics, was a response to a growing international concern that students worldwide were not getting enough to eat. While studies were conducted in the USA and Australia, no similar research has been done in South Africa.

“There have been many studies on the impact of poor nutrition on school kids,” says Dr Louise van den Berg, Senior Lecturer in the Department of Nutrition and Dietetics, “but almost no research on university students. South Africa is, overall, a food-insecure country, and the university wanted to establish how widespread this problem is among our students.”

The reasons given by students invariably referred to a lack of money, as many students were also supporting families. Some students admitted they lacked the knowledge to feed themselves properly, some admitted to borrowing money to buy food, and some even admitted to stealing food to survive.

“This research has confirmed something we have suspected for a long time,” Dr van den Berg states.

A number of students disclosed that they were reluctant to resort to the university feeding scheme, as they were ashamed to admit they did not have money to buy food.

This study is the first of its kind in South Africa, and underlines the fact that tertiary students are particularly vulnerable when it comes to food security. Often a student has to juggle their studies with their role as breadwinner.

A tiny ray of hope to students who find themselves as food insecure, is the No Student Hungry Programme that offers a food bursary to qualifying students.

This programme, initially established by Prof Jonathan Jansen, UFS Vice-Chancellor and Rector, and now managed by Grace Jansen and Karen Buys, offers a small allowance of about R30 per day to hungry students with an average academic achievement of 60% and above. This criterion discourages entitlement thinking and builds a strong sense of responsibility on the part of those who benefit from the food bursary.

Melanie, a second-year Geography and Environmental Management student, as well as a single mother, is a beneficiary of the NSH Programme. “This bursary helps me to get a balanced meal every day. It is one less worry for me. I dream of completing my studies so that I can be independent and provide my son with the life he deserves.”
